[Embodiment]
An example of a beverage plant producing Product A: Black Coffee, Product B: Standard Coffee and Product C: Milk Coffee is shown. In this embodiment, carbon dioxide (hereinafter referred to as "CO2") emitted in the process of obtaining each product is calculated for each product. Not only CO2 emitted from the combustion of gas in the beverage factory process, but also CO2 emitted in the upstream production process related to resources such as raw materials, parts and energy used in the beverage factory process Included in CO2 emissions. "Resources" in this embodiment is a generic term for raw materials, parts and energy required to manufacture a product.

FIG. 1A is a diagram showing a manufacturing process 106 for product A: black coffee.
Product A: The black coffee manufacturing process 106 includes a coffee liquid extraction step 100 a , a black coffee mixing step 102 and a black coffee bottling step 104 . In the coffee liquid extraction step 100a, gas and electric power are used to extract coffee concentrate from coffee grounds and water. The black coffee mixing step 102 uses gas and electricity to mix the coffee concentrate, sugar and water to produce a black coffee liquor. The black coffee bottling process 104 uses electricity to bottle and cap the black coffee liquid to produce bottled black coffee 108 . Black coffee generally refers to coffee without milk, whether sweetened or unsweetened. In the present application, sweetened coffee will be described as an example.

FIG. 1B is a diagram illustrating the manufacturing process 116 for product B: standard coffee.
Product B: The standard coffee manufacturing process 116 includes a coffee liquor extraction step 100b, a standard coffee mixing step 112, and a standard coffee bottling step 114. The coffee liquid extraction step 100b is similar to the coffee liquid extraction step 100a. The standard coffee mixing step 112 uses gas and power to mix the coffee stock, milk, sugar and water to form a standard coffee liquor. The standard coffee bottling process 114 uses electricity to bottle and cap the black coffee liquid to produce bottled standard coffee 118 .

FIG. 1(C) is a diagram showing a manufacturing process 126 for product C: milk coffee.
Product C: The milk coffee manufacturing process 126 includes a coffee liquid extraction step 100 c , a milk coffee mixing step 122 and a milk coffee bottling step 124 . The coffee liquid extraction step 100c is similar to the coffee liquid extraction step 100a. The milk coffee bottling process 124, similar to the standard coffee mixing process 112, uses gas and power to mix the coffee concentrate, milk, sugar and water to produce a milk coffee liquor. However, the mixing ratio is different from standard coffee. The milk coffee bottling process 124 uses electricity to bottle and cap the black coffee liquid to produce bottled milk coffee 128 .

FIG. 2A is a configuration diagram of planned consumption consumption data for product A: black coffee.
The basic unit indicates the expected or actual quantity of raw materials, parts, energy (fuel, electric power), etc. required to produce one product or a prescribed quantity of products. The planned basic unit indicates the basic unit scheduled at the planning stage. Raw materials, parts and energy are examples of categories of resources used to manufacture products. The planned basic unit data indicates the planned consumption of raw materials, parts, and energy resources. For example, when making one product A, it is planned to use 12 g of coffee powder, 10 g of sugar, and 0.2 L of water as raw materials. As parts, we plan to use one bottle and one cap. In addition, we plan to use 0.1 kWh of electric power and 6 L of gas as energy. Milk is not used in product A, but for comparison with other products, the expected basic unit of milk is indicated as 0 g.

FIG. 2B is a configuration diagram of planned CO2 emission data for product A: black coffee.
For each resource, the planned basic unit is multiplied by the CO2 emission rate for that resource to obtain the CO2 emissions based on the planned basic unit (hereinafter referred to as "planned CO2 emissions"). The CO2 emission rate indicates the amount of CO2 emission per unit amount of resource (eg, g (gram), L (liter), number and kWh, etc.) (see Figure 19). A CO2 emission rate may be empirically determined as the weight of CO2 produced when a unit amount of a resource is produced and when a unit amount is used.

For example, if the planned basic unit of coffee grounds "12g" is multiplied by the CO2 emission rate of coffee grounds "Rc", the planned CO2 emissions generated to obtain the planned amount of coffee grounds used for one product A is: It is calculated as “12×Rc[g]”. If 3 g of CO2 is emitted to obtain 1 g of ground coffee, the CO2 emission rate "Rc" is 3 [g/g]. This means that 12×3 [g] of CO2 will be discharged from one product A if it is carried out as planned. Since no milk is used, the projected CO2 emissions for milk is 0 g. "Rm" in the figure indicates the CO2 emission rate of milk. "Rs" indicates the CO2 emission rate of sugar. "Rw" indicates the CO2 emission rate of water. "Rb" indicates the CO2 emission rate of the bottle. "Rp" indicates the CO2 emission rate of the cap. "Re" indicates the CO2 emission rate of electricity. "Rg" indicates the CO2 emission rate of the gas. The CO2 emission rate of gas takes into account the amount of CO2 emitted during the gas production process and the amount of CO2 generated by combustion of gas in the beverage factory. Thus, the CO2 emission rate of a resource is the amount of carbon dioxide emitted by the production and/or use of the resource as a value per unit amount of the resource (e.g., g (grams), L (liters), number and kWh, etc.). Indicates the amount of carbon. Then, by totaling the planned CO2 emissions for each resource, the planned CO2 emissions corresponding to one product A can be obtained.

FIG. 3A is a configuration diagram of planned consumption consumption data for product B: standard coffee.
Product B: Standard coffee differs from black coffee in that it also uses milk as an ingredient. The planned unit consumption of ground coffee, sugar, water, electricity and gas is different from that of product A: black coffee. The planned unit consumption of bottles and caps is the same as for product A: black coffee. Product B: standard coffee has a smaller amount of raw coffee liquid to be mixed than product A: black coffee.

FIG. 3B is a configuration diagram of planned CO2 emission data for product B: standard coffee.
The method of obtaining the planned CO2 emission amount is the same as in the case of product A: black coffee.

FIG. 4A is a configuration diagram of planned consumption consumption data for product C: milk coffee.
Product C: Milk coffee also uses milk as an ingredient. The planned unit consumption of ground coffee, sugar, water, electricity and gas is different for product A: black coffee and product B: standard coffee. In addition, the planned unit consumption of milk is higher than that of product B: standard coffee. The planned unit consumption of bottles and caps is the same as for product A: black coffee and product B: standard coffee. Product C: With milk coffee, the amount of undiluted coffee solution to be mixed is even smaller, so the planned basic unit of coffee grounds is smaller than that of product B.

FIG. 4B is a configuration diagram of planned CO2 emission amount data for product C: milk coffee.
The method of obtaining the planned CO2 emission amount is the same as in the case of product A: black coffee and product B: standard coffee.

Generally, a method of calculating CO2 emissions based on the planned basic unit as described above is considered. However, the planned basic unit is an estimated value and may differ from the actual amount used. In other words, resources are not necessarily consumed according to the planned basic unit. For electricity and gas, in particular, it is difficult to accurately predict the unit consumption, and it may not match the actual amount used.

Therefore, this embodiment proposes a method of calculating CO2 emissions based on the actual amount of resource usage. For this purpose, we will obtain a basic unit (hereinafter referred to as “actual basic unit”) that is in line with the actual situation. For example, in the case of a beverage factory that manufactures the three products mentioned above, if it is possible to obtain the quantity of resources used in each of the manufacturing processes for each of the three products, divide the quantity used by the quantity produced. The actual basic unit can be obtained by In the following, the quantity of resources used will be referred to as the “quantity used,” the quantity of products manufactured will be referred to as the “manufactured quantity,” and the quantity of CO2 emitted (e.g., weight and volume) will be referred to as the “CO2 emission "Quantity". Further, the scheduled basic unit is the quantity planned to be used per product before manufacturing, and the actual basic unit is the quantity actually used per product in manufacturing. Planned basic unit and actual basic unit both mean the quantity of resources per product, and both are basic units.

FIG. 5 is a diagram illustrating an example of multiple dedicated manufacturing lines.
Ideally, a product A production line dedicated to the production process 106 of product A: black coffee, a production line of product B dedicated to the production process 116 of standard coffee, and a product C: production process 126 of milk coffee. A dedicated production line for the product C is provided separately.

The production line for product A includes a coffee liquid extraction machine 700a dedicated to the coffee liquid extraction process 100a, a liquid mixer 702a dedicated to the black coffee mixing process 102, and a bottling machine 704a dedicated to the black coffee bottling process 104. Power meter 710a measures the amount of power used by coffee brewer 700a, liquid blender 702a and bottling machine 704a. Gas meter 712a also measures the amount of gas used in coffee liquor extractor 700a and liquid blender 702a.

Then, by dividing the measured amount of power by the number of bottled black coffee 108 produced, the actual basic unit of power for product A: black coffee can be obtained. Further, by dividing the measured amount of gas by the number of bottled black coffees 108 produced, the actual unit consumption of gas in product A: black coffee can be obtained.

Similarly, the production line for product B includes a coffee liquid extraction machine 700b dedicated to the coffee liquid extraction process 100b, a liquid mixer 702b dedicated to the standard coffee mixing process 112, and a bottling machine 704a dedicated to the standard coffee bottling process 114. . The power meter 710b measures the amount of power used for the coffee liquid extractor 700b, the liquid mixer 702b, and the bottling machine 704b, and the gas meter 712b measures the amount of gas used for the liquid coffee extractor 700b and the liquid mixer 702b. measure.

Then, by dividing the measured amount of power consumption by the number of standard bottled coffees 118 produced, the actual basic unit of power for product B: standard coffee can be obtained. Further, by dividing the measured amount of gas used by the number of bottled standard coffees 118 produced, the actual gas consumption rate for product B: standard coffee can be obtained.

Similarly, the production line for product C includes a coffee liquid extraction machine 700c dedicated to the coffee liquid extraction process 100c, a liquid mixer 702c dedicated to the milk coffee mixing process 122, and a bottling machine 704c dedicated to the milk coffee bottling process 124. . The power meter 710c measures the amount of power used for the coffee liquid extractor 700c, the liquid mixer 702c, and the bottling machine 704c, and the gas meter 712c measures the amount of gas used for the liquid coffee extractor 700c and the liquid mixer 702c. measure.

Then, by dividing the measured amount of power consumption by the number of bottled milk coffee 128 produced, the actual power consumption of product C: milk coffee can be obtained. Further, by dividing the measured amount of gas used by the number of bottled milk coffees 128 produced, the actual gas consumption in product C: milk coffee can be obtained.

In this way, if a meter is installed for each product line, it is possible to measure the amount of gas and electricity used for each product. The gas meter 712d measures the total amount of gas supplied to the beverage factory from the city gas pipe. Power meter 710d measures the total usage of power supplied to the beverage plant from the power company transmission lines.

FIG. 6 is a diagram showing an example of one shared manufacturing line.
In factories that manufacture multiple types of products, the manufacturing line is often shared for each product. In this example, product A, product B and product C are manufactured on one shared manufacturing line. The shared production line includes a coffee liquor extractor 700d, a liquor blender 702d and a bottling machine 704d. The coffee liquid extractor 700d is used in the coffee liquid extraction processes 100a-100c. Liquid blender 702 d is used in black coffee blending process 102 , standard coffee blending process 112 and milk coffee blending process 122 . Liquid mixer 702d is used in black coffee bottling process 104, standard coffee bottling process 114 and milk coffee bottling process 124.

In this example, no gas meter is provided for the production line. Only a gas meter 712d is installed to collectively measure the amount of gas used in the beverage factory. As for power, similarly, no power meter is provided for the production line. Only a power meter 710d is installed to collectively measure the amount of power used in the beverage factory.

In addition, at the beverage factory, equipment that is not included in the production line is also in operation. Water heater 724 uses gas to heat water used when cleaning equipment and instruments. A lighting device 714 that illuminates the interior of the factory and an air conditioner 716 that air-conditions the interior of the factory use electric power. Since these facilities are also part of the environment necessary for the production of products, the CO2 emissions required for their energy are also included. However, it is not easy to decide how to distribute to the three products.

In this example, photovoltaic power generation is performed by the solar panel 718 as in-house power generation. The power that enters the distribution board 722 from the power controller 720 is preferentially used. Since power generated by photovoltaic power generation does not generate CO2 during power generation, CO2 emissions need only be considered for power supplied from power companies. Therefore, less power is supplied by the power company on sunny days, resulting in less CO2 emissions associated with power generation. Conversely, on cloudy or rainy days, more power is supplied by the power company, resulting in higher CO2 emissions associated with power generation. The use of photovoltaic power generation reduces CO2 emissions overall, but the extent to which photovoltaic power generation contributes to the reduction of CO2 emissions varies depending on the weather.

In this way, the CO2 emissions based on the gas consumption of the entire factory measured by the gas meter 712d and the power consumption of the entire factory measured by the power meter 710d are calculated for the manufacturing processes of the three types of products. It is a difficult problem to decide how to allocate

FIG. 7 is a diagram illustrating serial operation of multiple manufacturing processes.
In the example of FIG. 7, executing a plurality of manufacturing processes in a certain time period in parallel without executing them in another time period is called "serial operation". Specifically, coffee liquid extraction of the manufacturing process 106 of product A: black coffee is started at 9:00, and bottling of product A is finished by 11:00. 12:00 Product B: The coffee liquid extraction of the standard coffee manufacturing process 116 is started, and the bottling of Product B is finished by 14:00. At 15:00, coffee liquid extraction of the production process 126 of product C: milk coffee is started, and bottling of product C is finished by 17:00. Thus, the operating hours of the manufacturing process 106 for product A, the operating hours of the manufacturing process 116 of product B, and the operating hours of the manufacturing process 126 of product C are separated and do not overlap.

In this case, the CO2 emissions due to the amount of gas and electricity used during the operating hours (9:00 to 11:00) of the manufacturing process 106 of product A should be allocated to the manufacturing process 106 of product A. Similarly, the CO2 emissions due to the amount of gas and electricity used during the operating time (12:00 to 14:00) of the manufacturing process 116 of product B are allocated to the manufacturing process 116 of product B, The CO2 emissions due to the amount of electricity and gas used during the operating hours (15:00 to 17:00) can be allocated to the manufacturing process 126 of product C. Therefore, in the case of serial operation, it is easy to grasp the amount of electricity and gas used for each manufacturing process and reflect it in the amount of CO2 emissions for each product.

In addition, since the timing of using raw materials and parts is also divided in terms of time, it is easy to measure the quantity used for each manufacturing process. The measurement here includes the act of visually counting the number of parts, the act of measuring the volume of liquid and powder with a weighing scale, and the act of measuring the weight of the raw material itself excluding the container with a weighing scale. In other words, the measurement may be performed manually, or may be performed automatically by a sensor or the like attached to the device.

FIG. 8 is a diagram illustrating parallel operation of multiple manufacturing processes.
In the example of FIG. 8, executing multiple manufacturing processes at the same time during a certain period of time is called "parallel operation". Specifically, in the coffee liquid extraction process 100d from 9:00 to 10:00, the undiluted coffee liquids for the products A, B, and C are extracted together. That is, the coffee liquid extraction process 100d substantially corresponds to the coffee liquid extraction process 100a, the coffee liquid extraction process 100b, and the coffee liquid extraction process 100c. The amount of ground coffee used in the coffee liquid extraction step 100d is the sum of the amounts used for product A, product B and product C.

After that, between 10:00 and 12:00, the black coffee mixing process 102 is performed alone. Between 12:00 and 14:00, the black coffee bottling step 104 and the standard coffee mixing step 112 are performed simultaneously. Between 14:00 and 16:00, the standard coffee bottling process 114 and the milk coffee mixing process 122 are performed simultaneously. Between 16:00 and 18:00, the milk coffee bottling step 124 is performed alone.

In this way, depending on the time of day, a single manufacturing process may be carried out, or multiple manufacturing processes may be carried out at the same time. In practice, it may be more complicated than the example shown. Therefore, it is difficult to measure the consumption of electric power, gas, etc. according to the implementation status of manufacturing processes that are intricately combined. This embodiment proposes a method for simply estimating the actual unit consumption, assuming that the balance between products is correctly estimated regarding the unit consumption of resources such as electricity and gas. Details of the estimation method will be described later.

For example, when manufacturing 10 of each of the 3 types of products, the planned total amount of gas used is 240 L, but the total amount actually used is 480 L, double that amount. Assuming that the planned ratio of the gas consumption unit for the three types of products (example of the predetermined ratio) is 6:8:10, the ratio of the actual consumption unit is also estimated to be 6:8:10. As shown in FIGS. 2 to 4, the scheduled gas unit consumption for product A is 6 L, the scheduled gas unit consumption for product B is 8 L, and the scheduled gas unit consumption for product C is 10 L. This is the basis for the total planned usage of 240L of gas mentioned above. As mentioned above, if the actual amount used is doubled to 480 liters, the actual gas consumption of product A will be doubled to 12 liters, and the actual gas consumption of product B will also be doubled to 16 liters. As a result, it is estimated that the actual unit consumption of gas for product C has doubled to 20L. A detailed estimation method will be described later.

In addition, in cases where it is difficult to obtain the planned gas consumption rate with a high degree of accuracy, another index that is estimated to have a correlation with the gas consumption rate may be substituted. For example, if a pizzeria manufactures pizzas of different sizes, the exact gas intensity for each pizza used in the ovens for baking the large and small pizzas is not known. However, considering that large pizzas occupy a large area in the oven, while small pizzas fit in a small area and are baked in large quantities at one time, the gas usage per pizza is estimated by the weight and area of the pizza. is estimated to have a correlation with Therefore, if the gas unit consumption of the large and small pizzas is calculated so that the weight ratio or area ratio of the large pizza and the small pizza is constant, the actual unit consumption is estimated to some extent correct. Although gas is exemplified here, other resources such as electric power and coffee grounds (any resource classified into raw materials, parts, energy, etc.) are the same. In addition to weight and area, other indicators such as product volume or selling price may be substituted. It is quite possible that the volume or selling price will have a correlation with the basic unit resources related to CO2 emissions depending on the circumstances of each individual product.

FIG. 9 is a diagram showing an example of factors of variation in usage quantity.
As described above, the actual specific consumption is not necessarily the same as the planned specific consumption. One of the reasons for this is that it is difficult to accurately measure the quantity used, which is the basis of the basic unit, but another reason is that the quantity used varies due to various factors each time a product is manufactured. FIG. 9 shows an example of an event that happened at a beverage factory one day (February 10th) that resulted in different usage quantities for some resources than planned.

In the coffee liquid extraction process 100d, the amount of coffee ingredients coming out of the coffee powder was less than usual, and the undiluted coffee solution seemed to be diluted, so the amount of coffee powder was increased by 10%. Therefore, the actual amount of ground coffee used is 10% more than planned. In the black coffee bottling step 104, one cap was broken, so one cap was replenished. Therefore, the number of caps actually used is one more than planned. In the milk coffee mixing step 122, 1000 g of milk of questionable quality was discarded and 1000 g of milk was added. Therefore, the actual amount of milk used is 1000g more than planned. In addition, since the weather was fine that day (February 10), the amount of solar power generated was large, and the amount of power received from the electric power company was less than usual. Therefore, the actual amount of electricity used will be less than planned due to the amount of electricity obtained from solar power generation.

FIG. 10 is a configuration diagram of the planned usage quantity data.
Planned usage data can be generated prior to production implementation. The planned usage quantity data is generated based on the planned production quantity of each product and the planned basic unit data of each product. The term "planned production quantity" as used herein means the planned production quantity of a certain product per day.

We decided to manufacture 100 units of product A, 150 units of product B, and 50 units of product C for that day (February 10th). Therefore, the planned total production quantity (hereinafter referred to as “total planned quantity”) is 300 (=100+150+50). As shown in the figure, the planned production quantity of product A is "100", the planned production quantity of product B is "150", the planned production quantity of product C is "50", and the planned total quantity is "300". include.

For each resource of the 3 products, by multiplying the planned basic unit of the resource for that product (Figures 2(A), 3(A), and 4(A)) by the planned production quantity of that product, A planned usage quantity for that resource is determined. For example, for coffee grounds of product A, by multiplying the scheduled unit consumption of product A's coffee grounds "12 g" by the scheduled production quantity of product A "100", the planned usage quantity of coffee grounds in the manufacturing process 106 of product A is "1200g" is required.

In addition, by summing up the planned usage quantity of each product for each resource, the overall planned usage quantity can be obtained. For example, for coffee grounds, the total planned quantity to be used is ``3100'' by adding the planned quantity to be used for product A, ``1200g'', the planned quantity to be used for product B, ``1500g'', and the planned quantity to be used for product C, ``400g''. be done. Therefore, 3100 g of coffee grounds are required to manufacture products A, B, and C on February 10th. At this point, the planning stage ends.

At the manufacturing stage, the actual quantity used (hereinafter referred to as "actual quantity used") is measured. For coffee grounds, water, electricity and gas, we measure the total amount of actual usage for all products. That is, the measurement range is the "whole" including the manufacturing process 106 of product A, the manufacturing process 116 of product B, and the manufacturing process 126 of product C. On the other hand, for milk, sugar, bottles and caps, we will measure the actual quantity used for each product process. That is, the measurement range is the manufacturing process 106 of product A, the manufacturing process 116 of product B, or the manufacturing process 126 of product C. FIG. In this figure, the planned usage quantity corresponding to the actual usage quantity measured at the manufacturing stage is surrounded by a thick line frame. For example, as for coffee grounds, "3100 g" is planned to be used in "total", but how much coffee grounds are actually used is measured. As for sugar, how much is actually used in the manufacturing process 106 of product A, and how much is actually used in the manufacturing process 106 of product A? In addition, how much "2000 g" is actually used in the manufacturing process 126 of the product C is planned to be used.

FIG. 11 is a configuration diagram of calculation data for product A: black coffee.
The calculated data is the actual basic unit and actual CO2 emissions (hereinafter referred to as " This is data showing the process of calculating the actual CO2 emissions. In this figure, the measured amount of usage is enclosed in a thick line frame. For reference, planned values are shown in parentheses. The calculated data includes the actual production quantity. In this example, 100 bottled black coffee 108 were produced, all of which passed the final inspection to be shippable conforming. Non-conforming products in the final inspection are not included in the actual production quantity.

For example, for the coffee grounds, "3100g" was planned to be used for "whole", but in reality, "3410g", which is 10% more, is used. As for the caps, although "100" were planned to be used in the manufacturing process 106 of the product A, "101", which is one more, is actually used. Also, with respect to the electric power, "35 kWh" was planned to be used "total", but in reality, "17.5 kWh", which is half, is used.

Regarding the coffee grounds, water, electricity and gas for which the "total" actual usage quantity was measured, the usage quantity equivalent to the actual usage quantity of the manufacturing process 106 of product A from the actual usage quantity (hereinafter referred to as "estimated usage quantity") is estimated. The estimation method will be described later. The estimated quantity used is the quantity consumed in the manufacturing process 106 of the product A (hereinafter referred to as "consumed quantity"). For example, with respect to coffee grounds, the estimated amount of use "1320 g" of the manufacturing process 106 of the product A estimated from the actual amount of use "3410 g" of "whole" is copied as it is, and the consumption amount of the manufacturing process 106 of the product A "1320 g" is copied as it is. becomes. Consumption quantity refers to the quantity that forms the basis for calculating the actual basic unit. How to determine the estimated usage quantity of “1320 g” for the manufacturing process 106 of product A will be described later in relation to Equation 7.

On the other hand, for milk, sugar, bottles, and caps, for which the actual usage quantity was measured by manufacturing process, the actual usage quantity becomes the consumption quantity in that manufacturing process. For example, with regard to sugar, the actual usage quantity of "1000 g" in the manufacturing process 106 of product A is copied as it is and becomes the consumption quantity of "1000 g" in the manufacturing process 106 of product A.

For each resource, the actual basic unit is obtained by dividing the consumption quantity by the actual production quantity. For example, with respect to coffee grounds, by dividing the consumption amount of product A in the manufacturing process 106 of 1320 g by the actual production amount of product A of 100 pieces, the actual basic unit of product A is 13.2 g. As for sugar, by dividing the consumption amount of product A in the manufacturing process 106 of 1000 g by the actual production amount of product A of 100 units, the actual basic unit of product A of 10 g is obtained.

Then, for each resource, by multiplying the actual basic unit by the CO2 emission rate for that resource, the amount of CO2 actually emitted to obtain one piece of product A (hereinafter referred to as "actual CO2 emission amount") is calculated. be done. For example, with regard to coffee grounds, by multiplying the actual basic unit of product A "13.2 g" by the CO2 emissions of coffee grounds "Rc", the actual CO2 emissions of product A "13.2 x Rc" can be obtained. As for sugar, by multiplying the actual unit consumption of product A “10 g” by the CO2 emission amount “Rs” of sugar, the actual CO2 emission amount “10×Rs” of product A is obtained. Finally, for product A, the actual CO2 emissions of each resource are summed up to obtain the actual CO2 emissions per product A.

FIG. 12 is a configuration diagram of calculation data for product B: standard coffee.
As for ground coffee, both the amount of actual use and the amount of actual CO2 emissions have increased from the planned values. As for electric power, both the actual quantity used and the actual CO2 emissions are lower than planned values.

FIG. 13 is a configuration diagram of calculation data for product C: milk coffee.
In the case of product C: milk coffee, both the actual amount of coffee powder and milk used and the actual amount of CO2 emissions are higher than the planned values. As for electric power, both the actual quantity used and the actual CO2 emissions are lower than planned values.

The actual basic unit of each product is associated with the date of manufacture and stored as actual basic unit data in the actual basic unit data storage unit 262, which will be described later with reference to FIG. The actual CO2 emissions per product is associated with the date of manufacture and stored as actual CO2 emissions data in the actual CO2 emissions data storage unit 264, which will be described later with reference to FIG.

Here, a method for estimating the actual usage quantity of the manufacturing process 106 of product A from the "whole" actual usage quantity will be described. In this method, estimation calculation is performed so as to satisfy the following two conditions.

The first condition is that the actual usage quantity of a resource (for example, coffee grounds) measured “overall” is converted into the actual unit consumption of that resource for each type of product (for example, product A, product B, and product C). It means that it matches the sum of the values (products) multiplied by the actual production quantity of the type of product. The actual usage quantity “3410 g” measured “total” for the exemplified coffee grounds is the actual basic unit of product A “13.2 g” × the actual production quantity of product A “100”, and the actual basic unit of product B It matches the sum of "11g" x "150 pcs" of actual production quantity of product B and "8.8g" of actual basic unit of product C x "50 pcs" of actual production quantity of product B (1320g + 1650g + 440g).

The second condition is that the ratio of the actual unit consumption of the resource (eg, coffee grounds) measured “total” in each type of product (eg, product A, product B, and product C) matches a predetermined proportional division ratio. . The predetermined proportional division ratio indicates the ratio of consumption per piece of each type of product with respect to the "total" measured resource. The predetermined proportional division ratio is composed of terms for each type of product as shown in Equation (1).

Predetermined proportional division ratio = Product A term: Product B term: Product C term (Formula 1)

For example, assume that the product A term = 12, the product B term = 10, and the product C term = 8 (see Fig. 21). In this example, the value of each product item is matched with the planned basic unit of coffee grounds (“12 g”, “10 g” and “8 g”) for each product (Fig. 2 (A), Fig. 3 (A) , FIG. 4(A)). In other words, the ratio reference in this case is the scheduled basic unit of coffee grounds. A ratio basis refers to the type of information used as a predetermined proportional division ratio. An example of this predetermined apportionment ratio is that one of product A: black coffee consumes 20% more ground coffee than one of product B: standard coffee, and one of product C: milk coffee consumes product B. : Means consuming 20% less ground coffee than one cup of standard coffee.

Expression 2 holds when the estimated quantity used in the manufacturing process of each product is expressed in the form of a ratio. For those readers who need help understanding Equation 2, a supplementary explanation is provided. For example, we focus on the fact that the weight of the resource used is proportional to the amount of the extracted component. It is easy to understand if you imagine that the ratio of the weight of the resources and the ratio of the amount of the extracted components are the same for the three types of products. In other words, in this image, the left side of Equation 2 corresponds to the weight ratio of the resource, and the right side of Equation 2 corresponds to the ratio of the amount of ingredients (=the product of the amount of ingredients per product and the number of products). In this case, each product term is taken to be the amount of ingredients per product. However, the image described here is for helping understanding of Formula 2, and is not intended to limit the meaning of Formula 2. It is a convenient example, and the amount of ingredients should not necessarily be imagined, and it may be understood by imagining other concepts such as heat quantity, time, or commercial value.

Estimated quantity used in the manufacturing process 106 of product A: Estimated quantity used in the manufacturing process 116 of product B: Estimated quantity used in the manufacturing process 16 of product C = Product A term x Actual manufactured quantity of product A: Product B term x Actual production quantity of product B: Item of product C × Actual production quantity of product C (Formula 2)

Applying the numerical values exemplified for the coffee powder to Equation 2 yields Equation 3.

1320 g: 1650 g: 440 g = 12 x 100 pieces: 10 x 150 pieces: 8 x 50 pieces = 1200: 1500: 400 (Formula 3)

Therefore, the estimated usage quantity of each product in the manufacturing process can be obtained by proportionally dividing the "total" actual usage quantity according to the ratio of the estimated usage quantity in the manufacturing process of each product shown in Equation 2. The estimated usage quantity for the manufacturing process 106 of Product A is determined by Equations 4 and 5.

Estimated quantity used in the manufacturing process 106 of product A = actual quantity used of “total” × (term of product A × actual quantity manufactured of product A / denominator) (Formula 4)

Denominator = Product A term x Product A actual manufacturing quantity + Product B term x Product B actual manufacturing quantity + Product C term x Product C actual manufacturing quantity (Formula 5)

Applying the numerical values exemplified for coffee powder to Equations 5 and 4 yields Equations 6 and 7.

Denominator = 12 x 100 + 10 x 150 + 8 x 50 = 1200 + 1500 + 400 = 3100 (Formula 6)

Estimated quantity used in manufacturing process 106 of product A = 3410 g x (12 x 100/3100)
= 1320 g (equation 7)

The estimated usage quantity of the manufacturing process 116 for the product B is obtained by Equation 8, and the estimated usage quantity of the manufacturing process 126 for the product C is obtained by Equation 9.

Estimated usage quantity of manufacturing process 116 of product B = actual usage quantity of “total” × (term of product B x actual production quantity of product B / denominator) (Formula 8)

Estimated quantity used in the manufacturing process 126 of product C = actual quantity used of “total” × (term of product C × actual quantity manufactured of product C/denominator) (Formula 9)

Thus, based on the "total" actual usage of ground coffee and the predetermined proportion of ground coffee, the estimated usage of process 106 for product A, process 116 for product B, and process 126 for product C is calculated. can be asked for. Also, although coffee powder is used as an example here, water, electric power and gas are the same. In other words, based on the "total" actual amount of water used and a predetermined proportionate ratio of water, the estimated amount of water used in the manufacturing process 106 for product A, the manufacturing process 116 for product B, and the manufacturing process 126 for product C is obtained. be able to. Based on the "total" actual amount of power usage and a predetermined proportional division ratio of power, it is possible to determine the estimated amount of power usage in the manufacturing process 106 for product A, the manufacturing process 116 for product B, and the manufacturing process 126 for product C. can. Based on the "total" actual usage of gas and a predetermined proportional ratio of gas, the estimated usage of gas in the product A manufacturing process 106, the product B manufacturing process 116, and the product C manufacturing process 126 can be determined. can.

In addition, if non-conforming products are found in the final inspection, the actual production quantity will be less than the planned production quantity. For example, in the manufacturing process 106 of product A, production is started with the planned production quantity of "100", and if one nonconforming product is found in the final inspection, the actual production quantity becomes "99". Therefore, compared to the case where the actual manufacturing quantity is "100", the actual basic unit for each resource is 100/99 times, which is slightly larger. In other words, when the yield is poor, the actual basic unit increases.

The output unit 230 displays the CO2 emission rate of each resource included in the CO2 emission rate data (FIG. 19). If the CO2 emission rate has not yet been set for the first time, the CO2 emission rate will not be displayed.

A recording medium (e.g., barcode, QR code, RFID tag, etc.) is affixed to the main body, container, or package of raw materials and parts, and the storage location of CO2 emission data on the network is indicated on the recording medium. A URL (hereinafter referred to as "CO2 emission data URL") is recorded. When the input unit 220 receives a touch on the read button 802 of any resource, the graphic code reader 300 and the RFID reader 302 are ready for reading.

FIG. 18 is a configuration diagram of CO2 emission data of coffee grounds.
As shown in the figure, in the case of coffee grounds, for example, the acquisition unit 282 obtains the coffee grounds CO2 emission data URL "https://bbb.css" by reading the figure code 800a attached to the container of the coffee grounds with the figure code reader 300. xxx/trace/0122". Alternatively, the obtaining unit 282 obtains the coffee powder CO2 emission data URL from the RFID tag attached to the coffee powder container in the RFID reader 302 . Then, the obtaining unit 282 accesses the coffee powder CO2 emission data URL of the WEB server 400b of the business operator “bbb” that provides the coffee powder, and obtains the coffee powder CO2 emission data based on the response from the WEB server 400b. . The coffee powder as a product contains 100 g, and the total CO2 emission amount is shown as the CO2 emission amount (total). Also, the CO2 emission amount per 1 g is shown as the CO2 emission rate.

Return to the description of the input screen shown in FIG. The output unit 230 displays the CO2 emission rate obtained as described above. If there is no need to update the CO2 emission rate, the CO2 emission rate displayed on the input screen can be used without touching the read button 802 .

The output unit 230 displays a numeric area 804 of the actual quantity used for each resource. The worker inputs the value of the actual usage quantity in the numeric area 804, and the input unit 220 accepts the actual usage quantity of each resource and sets it in the calculation data (FIGS. 11, 12, and 13).

The output unit 230 displays a numeric area 808 of the actual production quantity for each product. The operator inputs the value of the actual production quantity in the numeric area 808, and the input section 220 receives the actual production quantity of each product and sets it in the calculation data (FIGS. 11, 12, and 13).

When the input unit 220 receives the touch of the ratio button 806 corresponding to the resource, the output unit 230 displays the proportional division ratio screen for that resource. However, the ratio button 806 is displayed only for the resource whose actual usage quantity is measured by "whole". This is because, for resources whose actual usage quantity is measured for each product, the usage quantity for each product is not estimated by proportional division (see FIGS. 11, 12, and 13).

FIG. 20 is a diagram showing an example of the proportional division ratio screen.
Here, an example of the proportional division ratio screen regarding electric power is shown. The output unit 230 displays the predetermined proportional division ratio of electric power with a large number. In this example, the term for product A is '0.10', the term for product B is '0.12', and the term for product C is '0.14' at the predetermined proportional division ratio of power. These values match the values of the planned specific consumption of electric power (FIGS. 2(A), 3(A), and 4(A)). That is, in the predetermined proportional division ratio of electric power shown in this example, the planned basic unit of electric power is used as the ratio standard.

As a general rule, we recommend that the planned basic unit of the resource be used as the ratio standard. However, it is also possible to use a ratio standard other than the planned basic unit of the resource. The output section 230 displays the ratio criterion candidates and the value of each product in the candidates. In this example, lot manufacturing time, lot heating time, capacity, product selling price, profit rate, cost rate, arbitrary criteria and scheduled unit consumption related to attributes other than those attributes are shown as candidates for ratio criteria. Not limited to this, any item can be a candidate for the ratio criterion. The operator can change the ratio criterion by selecting a ratio criterion candidate with the radio button 810 . In that case, each product's term in the proration ratio is replaced by each product's value in the modified ratio basis. When the arbitrary criterion is selected as the ratio criterion, the value input by the worker in the numeric area 812 is adopted as the arbitrary value of each product. When the decision button 814 is touched, the ratio standard selected on the proportional division ratio screen and the proportional division ratio based on that ratio basis are set as the proportional division ratio data. If the cancel button 816 is touched, the process ends without updating the proportional division ratio data. The proportional division ratio data will be described later with reference to FIG.

In addition, information on the ratio standard other than the planned basic unit is stored in the product basic data storage unit (not shown) as product basic data. A product basic data storage unit is included in the data storage unit 250 .

FIG. 21 is a configuration diagram of proportional division ratio data.
The apportionment ratio data stores the ratio standard and the ratio standard regarding the resource for which the actual usage quantity is measured "total". The figure also shows units such as g (grams) and L (liters) for ease of understanding.

Return to the description of the input screen shown in FIG. When the calculation button 809 is touched at the stage where the actual usage quantities of all resources and the actual production quantities of all products have been entered, the actual usage quantities of all resources and the actual production quantities of all products are converted into calculated data. (FIGS. 11, 12, and 13) is stored in the calculated data storage unit 260. FIG. Then, the specific consumption calculation unit 292 executes the actual consumption consumption calculation process shown in S42 of FIG. 16, and the emissions calculation unit 294 executes the CO2 emissions calculation process shown in S44. Then, the input screen processing ends, and the processing returns to S18 shown in FIG.

The actual specific consumption calculation process (S42 in FIG. 16) will be described. The basic unit calculation unit 292 calculates the actual basic unit for each resource (coffee powder, water, electric power, and gas) measured in the “total”. As described with reference to FIGS. 11, 12, and 13, the specific consumption calculator 292 first obtains the estimated usage quantity based on Equations 4, 5, 8, and 9.

Estimated quantity used in the manufacturing process 106 of product A = actual quantity used of “total” × (term of product A × actual quantity manufactured of product A / denominator) (Formula 4)

Denominator = Product A term x Product A actual manufacturing quantity + Product B term x Product B actual manufacturing quantity + Product C term x Product C actual manufacturing quantity (Formula 5)

Estimated usage quantity of manufacturing process 116 of product B = actual usage quantity of “total” × (term of product B x actual production quantity of product B / denominator) (Formula 8)

Estimated quantity used in manufacturing process 126 for product C =
= “Overall” actual quantity used x (term of product C x actual manufactured quantity of product C/denominator) (Formula 9)

The product A term, product B term, and product C term in the resource to be calculated are obtained from the proportional division ratio data of the proportional division ratio data storage unit 266 (FIG. 21). The actual production quantity of product A, the actual production quantity of product B, and the actual production quantity of product C are obtained from the calculation data (FIGS. 11, 12, and 13) in the calculation data storage unit 260. FIG. By substituting these into the above equations, the estimated quantity used in the manufacturing process 106 of product A, the estimated quantity used in the manufacturing process 116 of product B, and the estimated quantity used in the manufacturing process 126 of product C are calculated. Each estimated usage quantity is stored in the calculated data storage unit 260 as calculated data (FIGS. 11, 12, and 13).

The basic unit calculation unit 292, as described with reference to FIGS. 11, 12 and 13, specifies the consumption quantity of each resource for each product and stores it in calculation data. Then, the basic unit calculation unit 292 calculates the actual basic unit by dividing the consumption quantity by the actual production quantity of the product for each resource of each product. The calculated actual specific consumption is stored as calculation data (FIGS. 11, 12, and 13) in the calculated data storage unit 260, and is further stored as actual specific consumption data in the actual specific consumption data storage unit 262 in association with the manufacturing date. Stored.

The CO2 emissions calculation process (S44 in FIG. 16) will be explained. The emissions calculation unit 294 calculates the actual CO2 emissions for each resource for each product by multiplying the actual basic unit by the CO2 emission rate of the resource. The resource CO2 emission rate is obtained from the CO2 emission rate data (FIG. 19) in the CO2 emission rate data storage unit 254. FIG. The calculated actual CO2 emissions are stored in calculation data. The emissions calculation unit 294 adds up the actual CO2 emissions of each resource for each product to calculate the actual CO2 emissions per product. The actual CO2 emission amount of the product and the actual CO2 emission amount of each resource of the product are stored as actual CO2 emission amount data in the actual CO2 emission amount data storage unit 264 in association with the manufacturing date.

FIG. 22 is a flow chart showing the output screen processing process.
The flowchart shown in FIG. 22 shows detailed processing in the output screen processing (S18) shown in FIG. The output unit 230 repeats the following process for each product (S50). Output unit 230 processes product A, product B, and product C in this order, for example. The output unit 230 displays the output screen of each product (S52). The output screen will be described later with reference to FIG.

When the input unit 220 receives a touch on the specific consumption button (Y in S54), the process proceeds to specific consumption screen processing (S56). The specific consumption screen processing will be described later with reference to FIG. When the input unit 220 receives a touch on the registration button (Y of S58), the process proceeds to upload processing (S60). The upload process will be described later with reference to FIG. After finishing the upload process, the output screen of the product is closed. When the output unit 230 determines that there is an unprocessed product (Y of S62), the process returns to S50 and repeats the process for the next product. If there are no unprocessed products, output screen processing ends.

FIG. 23 is a diagram showing an example of an output screen.
Calculation results are mainly displayed on the output screen. Specifically, the output unit 230 displays the planned basic unit of each resource included in the planned basic unit data of the target product (FIGS. 1(A), 2(A), and 3(A)). Planned unit consumption is displayed as reference information for comparison with the calculated actual unit consumption.

The output unit 230 displays the actual basic unit of each resource of the target product included in the actual basic unit data. Furthermore, the output unit 230 displays the actual CO2 emissions of each resource of the target product included in the actual CO2 emissions data, and the total actual CO2 emissions of the target product.

When the input unit 220 receives a touch on the consumption unit button 822, the output unit 230 displays the consumption consumption screen for the product. The specific consumption screen will be described later with reference to FIG.

When the input unit 220 receives a touch on the registration button 824, the upload unit 286 uploads the CO2 emissions data to the WEB server in the upload process (S60 in FIG. 22). That is, the product CO2 emission data is stored in the storage location indicated by the product CO2 emission data URL. Alternatively, the URL recording unit 288 may record the CO2 emission data URL on a recording medium attached to the product. The process of recording on the recording medium by the URL recording unit 288 may be performed before uploading or may be performed after uploading.

FIG. 24 is a configuration diagram of CO2 emission data for product A: black coffee.
In this example, the illustrated product A: black coffee of CO2 emissions data is stored. Therefore, when the black coffee CO2 emission data URL recorded in the graphic code 800b attached to the bottled black coffee 108 is accessed, this CO2 emission data is transmitted as a response.

The CO2 emissions data includes the CO2 emissions of each resource in addition to the CO2 emissions (total) that indicates the CO2 emissions of the entire product. Each resource is associated with a CO2 emission data URL in which emission data of the resource is stored. Also included is a CO2 emission rate that indicates the amount of CO2 emitted per unit volume (ml in this example).

FIG. 25 is a diagram showing an example of a specific consumption screen.
The worker can refer to current and past actual consumption consumption on the consumption consumption screen, and can modify the planned consumption consumption.

The output unit 230 displays the planned consumption of the resources included in the planned consumption consumption data of the target product (FIGS. 1A, 2A, and 3A) in the numerical area 830 of the planned consumption of each resource. Show units. The worker can rewrite the value of the planned basic unit of resource displayed in the numeric area 830 . The input unit 220 accepts the rewritten value of the planned specific consumption of the resource.

The output unit 230 displays the current actual unit consumption and past actual unit consumption of each resource. In addition, the output unit 230 displays the average of the actual basic unit for 10 days including the current time for each resource. In this example, actual basic units and averages for 10 days including the current time are displayed, but a period longer than 10 days or a period shorter than 10 days may be targeted.

In particular, the actual unit consumption of each resource (coffee grounds, water, electricity, and gas) measured in the “total” is based on estimates, so there is a possibility of errors if the apportionment ratio does not match the actual situation. There is If the balance of the actual production quantity of each product fluctuates (for example, if there are days when more product A is manufactured and there are days when more product C is manufactured), the error in the apportionment ratio will cause the actual basic unit to increase. Variation is possible. By referring to the actual basic unit for the past, the worker can grasp the magnitude of the variation and estimate the appropriateness of the apportionment ratio. When the worker touches the apply button 832 and the input unit 220 accepts the touch on the apply button 832, the average value of the actual basic unit for 10 days is displayed in the planned basic unit numerical value area 830. copied. In other words, the average value of the actual specific consumption can be fed back to the planned specific consumption.

When the operator turns on the automatic application switch 834, the automatic updating unit (not shown) of the data processing unit updates the actual data for a predetermined period (for example, 10 days) including this time at predetermined intervals (for example, every 10 days). Find the average of the units and copy the average value to the scheduled intensity. In other words, the average value of the actual specific consumption is automatically fed back to the planned specific consumption. When the operator turns on the fully automatic application switch 836, all the displayed automatic application switches 834 are turned on. Here, an example of average is shown, but other statistical values such as mode or median may be used.

If the standard for the apportionment ratio of a certain resource is set as the planned unit consumption of that resource, and the average value of the actual unit consumption is manually or automatically fed back to the planned unit consumption, the variation in the actual unit consumption will naturally decrease, and the planned unit consumption will decrease. is expected to be adjusted to match the actual situation.

When the input unit 220 receives a touch on the enter button 838, the value of the planned consumption consumption numerical value area 830 is written in the planned consumption consumption data. Also, if the automatic application switch 834 is ON, the automatic updating unit starts the process of automatically feeding back the average value of the actual specific consumption of the resource to the planned specific consumption. Then, the processing of the basic unit screen is completed. When the input unit 220 accepts the cancel button 840, the processing of the specific consumption screen is terminated.

FIG. 26 is a diagram showing an example of a CO2 emission amount display screen.
A user such as a purchaser of the product can refer to the contents of the CO2 emission amount data shown in FIG. 24 by reading the graphic code or RFID tag with the user terminal. In the black coffee CO2 emissions data window 602 shown here, the CO2 emissions of each resource are also displayed in addition to the "whole" CO2 emissions of the product.

Also, when a reference button 850 displaying a resource name is touched, a CO2 emissions data window showing the contents of CO2 emissions data obtained from the CO2 emissions data URL of the resource is displayed. This figure shows an example in which the ground coffee reference button 850 is touched and the ground coffee CO2 emissions data window 604 is displayed. As for the content of the CO2 emission data, the graphic code or RFID tag may be changed so that the display is changed for each product lot, or the latest data may be displayed regardless of the product lot.

FIG. 27 is a functional block diagram of the user terminal 500. As shown in FIG.
The user terminal 500 includes a user interface processing section 510 , a data processing section 580 , a network communication section 540 , a near field communication section 542 and a data storage section 550 . The user interface processing unit 510 receives user operations via a mouse or a touch panel, and is in charge of user interface processing such as image display and audio output. A network communication unit 540 is in charge of communication processing via a network. The short-range wireless communication unit 542 takes charge of communication processing by short-range wireless. The data storage unit 550 stores various data. The data processing unit 580 executes various processes based on the data acquired by the network communication unit 540 and the short-range wireless communication unit 542 and the data stored in the data storage unit 550 . Data processing unit 580 also functions as an interface for user interface processing unit 510 , network communication unit 540 , short-range wireless communication unit 542 and data storage unit 550 . In addition, user terminal 500 incorporates RFID reader 544 and camera 546 (or graphic code reader). The RFID reader 544 and camera 546 (or graphic code reader) may be external.

The user interface processing unit 510 has a reception unit 520 for inputting data by user operation and an output unit 530 for outputting data to be provided to the user. Output unit 530 includes a CO2 emission data output unit 532 that outputs CO2 emission data.

The data processing unit 580 includes a URL acquisition unit 582 that acquires the CO2 emissions data URL, and a window control unit 584 that controls windows displayed on the display.

The URL acquisition unit 582 causes the camera 546 (or a graphic code reader) to photograph the graphic code (for example, bar code or QR code) attached to the product, or causes the RFID reader 544 to read the RF tag attached to the product. to obtain the CO2 emissions data URL of the product.

The network communication unit 540 accesses the acquired CO2 emission data URL and downloads the product's CO2 emission data. Downloading means receiving data from a computer (for example, a WEB server) on a network. The received data may be stored in a non-volatile storage area (e.g. hard disk drive) or only in a volatile storage area (e.g. random access memory) without being stored in non-volatile storage area. may be stored. The CO2 emission data output unit 532 generates a product CO2 emission data window based on the downloaded CO2 emission data and displays it on the display. The CO2 emission data output unit 532 may display part of the CO2 emission data of the product, or may display all of the CO2 emission data of the product. The CO2 emission data output unit 532 may output part or all of the product CO2 emission data in a manner other than display (for example, printing or transmission).

When accepting portion 520 accepts a touch on reference button 850, window control portion 584 refers to the CO2 emission rate data (FIG. 19) of CO2 emission rate data storage portion 254 to obtain the resource CO2 emission amount data URL. Identify. Then, a window for resource CO2 emission data is displayed in the same manner as in the case of product CO2 emission data.

According to embodiments, it is possible to easily estimate the actual unit consumption that fits the actual situation, assuming that the consumption of resources such as coffee grounds, electricity and gas is correctly estimated among the products. . As a result, the CO2 emissions of the resources used by the business can be allocated to any product manufactured by the business. In other words, the CO2 emissions of the consumed resources are covered by the entire product manufactured by the business without omission or duplication. In addition, it is expected that many businesses will calculate the CO2 emissions from their own products and disclose the CO2 emissions from their products to consumers and the like.

The reason for focusing on the planned basic unit ratio is that it is expected that the business operator, as a party and an expert, will accurately anticipate the balance between products regarding the resource basic unit. In other words, there is a high possibility that the actual unit consumption can be estimated more accurately if the ratio of the planned unit consumption is used for proportional division.

In addition, we provided a mechanism that allows users such as product purchasers to easily refer to CO2 emissions using recording media and a web environment.

[Modification]
In the above example, the CO2 emission data URL is recorded on a recording medium (for example, barcode, QR code, RFID tag, etc.), but the CO2 emission data may be recorded on the recording medium. good. In that case, the acquisition unit 282 of the CO2 emission calculation device 200 can acquire the CO2 emission data directly from the recording medium. Further, instead of the upload unit 286 of the CO2 emission calculation device 200, an emission data writing unit (not shown) is provided. The emissions data writing unit writes CO2 emissions data on a recording medium attached to the product (for example, bar code, QR code, RFID tag, etc.). Also, instead of the URL acquisition unit 582 of the user terminal 500, a discharge amount data acquisition unit (not shown) may be provided. The emissions data acquisition unit acquires CO2 emissions data directly from a recording medium attached to the product (eg, barcode, QR code, RFID tag, etc.).

Furthermore, when recording the CO2 emission data on a recording medium, the CO2 emission data is encrypted in the encryption/decryption unit 290 of the CO2 emission calculation device 200 and then encrypted on the recording medium (for example, barcode, QR code, or RFID tag, etc.). Further, the CO2 emission data uploaded in the embodiment may be encrypted by the encryption/decryption unit 290 before being uploaded. Further, an encryption/decryption unit (not shown) may be provided in the user terminal 500, and the encrypted CO2 emission data may be decrypted in the encryption/decryption unit.

The web server that stores the CO2 emissions data does not have to be a web server operated by the product operator. A web server or the like that collectively manages CO2 emission data on products of a plurality of businesses may be used.

In the output unit 230, a printer may be used to print the CO2 emissions in numbers and characters on the product body, product packaging, product container, seal label, slip, or the like.

In the embodiment, examples of gas and electric power are shown as energy resources, but other fuels such as coke, petroleum, light oil, and gasoline may also be targeted. Also, as indirect energy, resources such as heat and steam may be targeted. Resources also include catalysts and the like.

In the embodiments and variations, coffee and pizza have been described as easy-to-understand examples, but the disclosure herein can also be applied to the manufacture of other products such as batteries, automobiles, and energy. It goes without saying that we can. In addition, the production of products that can absorb CO2 during the production process (eg, carbonated water, beer, etc.) may be counted as "negative emissions." That is, the CO2 emission amount may be calculated as a negative value.

Greenhouse gases (GHG) are not limited to CO2, but also include methane and nitrous oxide generated by livestock, and fluorocarbons used in the semiconductor process and manufacturing of home appliances. The techniques of the embodiment and modifications may be applied to emissions of greenhouse gases other than CO2.
