Description

Server, method, and computer-readable storage medium for determining carbon emission reduction contribution by second-hand transaction based on transaction price TRANSACTION WAS CONCLUDED}

Embodiments of this document relate to a server, a method, and a computer readable recording medium for determining a contribution to carbon emission reduction by a used transaction based on a transaction price.

Currently, the world is implementing a gradual reduction of carbon emissions, one of the main causes of global warming, through the Kyoto Protocol. Under the Kyoto Protocol, the obligatory bureau or company sets a limit on carbon emissions for each period, and is obliged to trade carbon credits for excess emissions.

Here, carbon credits are a concept that encompasses quotas and credits. Allocation refers to carbon emission rights paid to major carbon emission sources such as power generation facilities or production facilities, equal to the total amount of carbon emission set by the country or region. Credit refers to the emission rights paid to the project as a certificate that the carbon emission has been reduced compared to the standard forecast for the carbon reduction project. According to the protocol, an obligatory country or a company can receive a new allocation of carbon credits in recognition of the reduction performance generated by investing in a carbon emission reduction project.

Accordingly, mandating countries or corporations are encouraging carbon emission reduction, and efforts are underway to reduce carbon emission by giving incentives to various activities that reduce carbon emission.

On the other hand, conducting second-hand trading of goods, not only at the corporate level but also at the individual level, is one of the important ways to reduce carbon emissions. However, since the second-hand transaction is a method of indirectly reducing carbon emissions by reducing the manufacturing of new products or the disposal of existing products, it is difficult to calculate the amount of reduced carbon emissions due to the second-hand transaction.

Therefore, in order to stably operate the total carbon emission system and encourage many people to reduce carbon emissions, it is necessary to determine the amount of carbon emissions saved by individuals involved in used transactions and to provide fair compensation accordingly. do.

3 is a flowchart of operations performed by the server 100 according to the first embodiment. In this document, the first embodiment includes embodiments in which the carbon emission reduction contribution by second-hand transactions is determined based on the 'time' of transaction occurrence. An operation of the server 100 according to the embodiment of FIG. 3 may be understood as an operation performed by the processor 120 .

In step S1010 , the server 100 may obtain second-hand transaction data including information on a used transaction target product, information on a subject who performed a second-hand transaction, and information about a time when the second-hand transaction occurred.

The product information may include information on the product type, model name, production year, purchase year, new product price, used price, and the like.

The information of the subject who performed the used transaction may include seller's information, buyer's information, and information on the broker of the used transaction. For example, a brokerage entity for used transactions may include various entities that help in used transactions, such as a company that provides a website for performing used transactions and a company that stores used products.

The information on the time when the used transaction of the product occurs may include time information of various standards that can be recognized as successful transaction, such as the time when the information on the product is uploaded and the time when the used price of the product is deposited to the seller.

In step S1020 , the server 100 may determine a first carbon reduction amount saved by the seller and a second carbon reduction amount saved by the buyer based on the information about the average lifespan of the product and the time when the used transaction occurs.

4 is an exemplary diagram for explaining an operation of determining, by the server 100, a carbon reduction amount based on information about a time when a used transaction occurs, according to an exemplary embodiment.

Referring to FIG. 4 , the server 100 calculates a first carbon reduction amount based on carbon emissions generated by the product after the time when the used transaction occurs, and calculates a first carbon reduction amount based on the carbon emissions generated by the product before the time when the used transaction occurs. 2 Carbon savings can be calculated.

For example, the server 100 may include a first carbon amount corresponding to a ratio from the time when the used transaction of the product occurs to the time when the average lifespan of the product ends among the amount of carbon emitted by use during the average lifespan of the product, and the product The first carbon reduction amount can be derived by summing the second carbon amount emitted upon disposal. That is, the embodiment of this document is considered to reduce additional carbon emissions generated during the remaining life of the product by selling the product by the seller, and to reduce carbon emissions generated during disposal of the product by preventing the disposal of the product. Carbon savings can be calculated. For example, the server 100 determines the amount of carbon emitted during the production of the product and the amount of carbon emitted during the average lifespan of the product, from the time when the product is shipped or first purchased to the time when the used transaction of the product occurs. The second carbon reduction amount may be derived by summing the fourth carbon amount corresponding to the ratio up to . In other words, the embodiments of this document indicate that the purchaser purchases the product, thereby reducing the carbon emissions generated during the production of the product by preventing additional production of the new product, and reducing the carbon emission that would have occurred when the new product was purchased and used. It is possible to calculate the second carbon reduction amount by looking at it.

Hereinafter, an embodiment for deriving the first to fourth carbon amounts will be described.

For example, the server 100 may pre-store or obtain information about the average lifespan of the product, data defining the amount of carbon emitted when the product is used, the production time of the product, and the purchase time of the product by the seller. For example, the server 100 may store example information in Table 1 below as data in which the amount of carbon emitted when an item is used is defined.

product emissions refrigerator 0.287 (tCO _2eq / piece) TV 0.374 (tCO _2eq / piece) washing machine 0.376 (tCO _2eq / piece) Smartphone 0.0389 (tCO _2eq / piece) laptop 0.171 (tCO _2eq / piece) desktop 0.223 (tCO _2eq / piece) tablet 0.0879 (tCO _2eq / piece) Gas range 0.176 (tCO _2eq / piece) electric range 0.176 (tCO _2eq / piece) Microwave 0.0581 (tCO _2eq / piece) coffee machine 0.0416 (tCO _2eq / piece) dish wash machine 0.143 (tCO _2eq / piece)

The server 100 may determine the first amount of carbon based on the data defining the average life span of the product, the amount of carbon emitted during use of the product, and the year of production or purchase of the product. For example, as shown in FIG. 4, the average life of a specific product is 5 years, the carbon emission is 3000 tCO ₂ when the product is used during the average lifespan (5 years) of the product, and the seller purchases the product and uses it for 1 year , of the amount of carbon emitted by use during the average lifespan of the product, corresponding to the ratio from the time when the used transaction of the product occurs to the time the average lifespan of the product ends (ex. the year of production or the time of purchase plus the average lifespan) The first carbon amount can be determined as (5-1)/5*3000 = 2400 tCO ₂ .

Meanwhile, according to an embodiment, a fixed time may be applied regardless of the actual used transaction time to apply the time when the used transaction occurs. For example, the point in time statistically determined that used transactions start to occur after a specific product is released can be fixedly applied as the time when used transactions occur. For example, if the point at which used transactions start after product A is released is one year, the seller's usage period may be fixedly applied as one year when the above-described embodiment is applied.

For example, the server 100 may pre-store or obtain data defining carbon emissions by discarded weight of parts constituting the product in advance. The server 100 may determine the second amount of carbon based on data defining carbon emissions by discarded weight of parts constituting the product.

5 is an exemplary diagram of data in which carbon emissions per manufacturing weight or carbon emissions per disposal weight of a part made of a predetermined material are defined according to an embodiment.

Referring to Figure 5, the data defining the carbon emission is the manufacturing or disposal weight of the material constituting the parts of a specific product (ex. Titanium 3AL-2.5V Alloy, Titanium 6AL-4V Alloy, 6061 aluminum alloy, 7005 aluminum alloy, etc.) It can store star carbon emissions. For example, (b) of FIG. 5 is data defining carbon emissions at the time of disposal when parts of an article (eg bicycle) are made of Titanium 6AL-4V Alloy. The data defining the carbon emission can store the composition ratio of elements constituting Titanium 6AL-4V Alloy and the carbon emission amount when disposing of each element. The composition ratio of elements constituting Titanium 6AL-4V Alloy and carbon emission per element Based on this, Titanium 6AL-4V Alloy can be saved by emitting 9.1 kgCO2e per kg of carbon when 1 kg is disposed of.

The server 100 can identify the parts constituting the item by specifying the item to be used for transaction, and the server 100 determines the amount of the part in the carbon emission by discarded weight of the part according to the data in which the carbon emission is defined. By multiplying by weight, the carbon footprint of each part at disposal can be calculated. For example, if the product is a bicycle, the server 100 specifies the material of the parts constituting the bicycle, and the server 100 determines the carbon emissions of the specified parts according to the data in which the carbon emissions by waste weight are defined. It is possible to calculate the carbon footprint at disposal of each part by multiplying by its weight. Through this operation, the server 100 may determine the second carbon amount (eg, 1000 tCO ₂ in the case of FIG. 4 ) according to the disposal of the bicycle by summing up the carbon emissions calculated for all the determined parts.

For example, the server 100 may pre-store data defining carbon emissions per manufacturing weight of parts constituting the product or obtain it from the outside. The server 100 may determine the third amount of carbon based on data defining carbon emissions by manufacturing weight of parts constituting the product.

Again, referring to FIG. 5, the data defining the carbon emission amount is the manufacturing or Carbon emissions by weight of waste can be saved. For example, (a) of FIG. 5 is data defining carbon emissions when bicycle parts are made of Titanium 3AL-2.5V Alloy. The data defining the carbon emission can store the composition ratio of elements constituting Titanium 3AL-2.5V Alloy and the carbon emission per element, and the composition ratio of elements constituting Titanium 3AL-2.5V Alloy and carbon emission per element Based on this, Titanium 3AL-2.5V Alloy can be stored as emitting 8.69 kgCO2e per kg of carbon when producing 1 kg.

The server 100 can identify the parts constituting the item by specifying the item to be used for transaction, and the server 100 calculates the amount of the part in terms of carbon emissions by manufacturing weight of the part according to the data in which the carbon emission amount is defined. By multiplying by weight, you can calculate the carbon footprint of manufacturing each part. For example, if the product is a bicycle, the server 100 specifies the material of the parts constituting the bicycle, and the server 100 calculates the carbon emissions of the specified parts according to the data in which the carbon emissions per manufacturing weight are defined. You can calculate the carbon footprint of manufacturing each part by multiplying it by its weight. Through this operation, the server 100 may determine the third carbon amount (eg, 10000 tCO ₂ in the case of FIG. 4 ) according to the manufacture of the bicycle by summing up the carbon emissions calculated for all the determined parts.

For example, the server 100 may pre-store data defining the average lifespan of the product, the amount of carbon emitted when the product is used, and the year of production of the product, or may acquire it from the outside. The server 100 may determine the fourth amount of carbon based on data defining the average lifespan of the product, the amount of carbon emitted during use of the product, and the year of production of the product. For example, as shown in FIG. 4, the average life of a specific product is 5 years, the carbon emission is 3000 tCO ₂ when the product is used during the average lifespan (5 years) of the product, and the seller purchases the product and uses it for 1 year , 1/5*3000 = 600 The fourth carbon amount corresponding to the ratio from the time when the product is produced, released, or first purchased to the time when the used transaction of the product occurs among the amount of carbon emitted by use during the average life of the product It can be determined by tCO ₂ .

In step S1030 , the server 100 may determine the contribution of the subject involved in used transaction data based on the first carbon reduction amount and the second carbon reduction amount. For example, referring to FIG. 4, the server 100 calculates the total amount of carbon emitted during the production (10000 tCO ₂ ), use (3000 tCO ₂ ), and disposal (1000 tCO ₂ ) of the product by the seller, out of 14000 tCO 2 . Calculated as reducing 1 carbon savings (3400 tCO ₂ ), the seller's contribution can be determined as 3400/14000*100 = 24.3%. The server 100 reduces the second carbon reduction amount (10600 tCO 2 ) of the total carbon amount of 14000 tCO 2 emitted during the production (10000 tCO ₂ ), use (3000 tCO ₂ ), and disposal (1000 tCO _{2 )} of the product by the buyer. Calculated as having done so, the buyer's contribution can be determined as 10600/14000*100 = 75.7%.

In another, first embodiment, as shown in FIG. 6, the server 100 may further include a relaying entity that relays a used transaction as an entity related to the used transaction, thereby determining the amount of carbon savings and the contribution of the relaying entity involved. .

6 is an exemplary diagram for explaining an operation in which the server 100 determines contributions between a seller, a buyer, and a relay entity based on used transaction time according to an embodiment.

Referring to FIG. 6 , in step S1020 , the server 100 may additionally determine a third carbon reduction amount saved by a relaying entity providing a service for relaying used transactions. In this case, the relay subject may include an operator of the server 100 . The relaying subject may include a third relaying subject separate from the server 100 .

The server 100 may determine the extended lifespan of the product compared to the average lifespan of the product based on information on the repair of the product by the relay subject, and provide the amount of carbon saved by use during the extended lifespan of the determined product. 3 It can be determined by the amount of carbon savings. That is, in the embodiment of this document, the third carbon reduction can be calculated considering that carbon emissions are reduced by preventing the use of another third item for the period in which the life of the item is extended by the relay subject repairing the item. . For example, as shown in FIG. 6, in a state where the average lifespan of a specific item is 5 years and the carbon emission is 3000 tCO ₂ when the item is used during the average lifespan (5 years) of the item, the relay subject repairs the item and When it is determined that is extended by one year, the third carbon reduction amount saved by use during the extended life of the product can be determined as 1/(5+1)*3000 = 500 tCO2. In this case, as shown in the example of FIG. 6, when calculating the seller's first carbon savings and the buyer's second carbon savings, the life of the product is the original life (5 years) by adding the extended life (1 year) to the first carbon savings. A reduction amount and a second carbon reduction amount can be calculated.

In addition, the server 100 may determine the storage period until the relay subject receives the goods from the seller and delivers the goods to the buyer, and calculates the amount of carbon saved by use during the storage period of the determined goods as a third carbon reduction amount. can be determined by In other words, the embodiment of this document reduces carbon emissions by preventing the use of another third item by preventing the use of the item by storing the item by the relay subject storing the item and extending the life of the item by the period of storage. Thus, the third carbon reduction amount can be calculated. For example, as shown in FIG. 6, the average lifespan of a specific item is 5 years, the carbon emission is 3000 tCO ₂ when the item is used during the average lifespan (5 years) of the item, and the period in which the relay entity stores the item is 1 years, the third carbon reduction amount saved by use during the storage period of the article can be determined as 1/(5+1)*3000 = 500 tCO2. In this case, as in the example of FIG. 6, when calculating the seller's first carbon reduction amount and the buyer's second carbon reduction amount, the first carbon reduction amount is obtained by adding the storage period (1 year) to the original life span (5 years) of the product life. and second carbon savings can be calculated.

In step S1030 , the server 100 may determine the contribution of the subject involved in used transaction data based on the first carbon reduction amount, the second carbon reduction amount, and the third carbon reduction amount. For example, referring to FIG. 6, the server 100 calculates the seller's production (10000 tCO ₂ ), use (3000 tCO ₂ ), and disposal (1000 tCO ₂ ) of the total amount of carbon emitted during the course of 14000 tCO 2 . By calculating that 1 carbon reduction (3000 tCO ₂ ) has been reduced, the seller's contribution can be determined as 3000/14000*100 = 21.4%. The server 100 reduces the second carbon reduction amount (10500 tCO 2 ) of the total carbon amount of 14000 tCO2 emitted during the production (10000 tCO ₂ ), use (3000 tCO ₂ ), and disposal (1000 tCO _{2 )} of the product by the buyer. Calculated as having done so, the buyer's contribution can be determined as 10500/14000*100 = 75%. The server 100 determines the third carbon reduction amount (500 tCO 2 ) of the total carbon amount _of 14000 tCO 2 emitted during the production (10000 tCO ₂ ), use (3000 tCO ₂ ), and disposal (1000 tCO ₂ ) of the goods by the relaying subject. Calculated as reduced, the contribution of the relay subject can be determined as 500/14000*100 = 3.6%.

After step S1030, the server 100 may aggregate revenues generated based on used transaction data, and distribute some of the determined revenues to each subject based on the contribution or carbon savings of each subject. For example, the server 100 may aggregate revenue generated by performing a revenue generation event based on used transaction data, and distribute the revenue according to the contribution of each entity. For example, a revenue-generating event includes the act of generating revenue from the proof data itself, or the act of generating revenue by acquiring carbon credits through proof data and then selling the carbon credits through an emission trading market or an emission trading certification body. can do.

7 is a flowchart of operations performed by the server 100 according to the second embodiment. In this document, the second embodiment includes embodiments in which the carbon emission reduction contribution due to the used transaction is set based on the 'price' of the transaction. The operation of the server 100 according to the embodiment of FIG. 7 may be understood as an operation performed by the processor 120 .

In step S2010, the server 100 may obtain second-hand transaction data including information on the used transaction target product, information on the subject of the second-hand transaction, and information on the price at which the second-hand transaction was concluded.

The product information may include information on the product type, model name, production year, purchase year, new product price, used price, and the like.

The information of the subject who performed the used transaction may include seller's information, buyer's information, and information on the broker of the used transaction. For example, a brokerage entity for used transactions may include various entities that help in used transactions, such as a company that provides a website for performing used transactions and a company that stores used products.

The information on the price at which the second-hand transaction of the product is completed may include price information based on various criteria that can be recognized as a successful used transaction, such as second-hand price information of the product uploaded by the seller and a price deposited from the buyer.

In step S2020, the server 100 determines a first contribution contributed by the seller to replace the disposal of the product and a second contribution contributed by the buyer to replace the production of the product based on the information on the new price and the used transaction price of the product. can do. For example, the server 100 may set the ratio of the used transaction price to the sum of the new product price and the used transaction price as the first contribution, and set the ratio of the new product price to the sum price as the second contribution. . For example, if the new price is 10,000 won and the used price at which the transaction is concluded is 5,000 won, the server 100 considers that the seller has reduced carbon emissions by replacing the disposal of the product, and the first contribution is 5000 / (10000 + 5000) *100 = 33.3% can be set. In addition, the server 100 may set the second contribution as 10000/(10000+5000)*100 = 66.7% considering that the purchaser has reduced carbon emissions by substituting the product.

In step S2030, the server 100 may determine a first carbon reduction amount saved by the seller and a second carbon reduction amount saved by the buyer based on the first contribution and the second contribution. The server 100 may determine the amount of carbon emitted by at least one process of production, use, and disposal of the product. For example, the server 100 may calculate carbon emissions generated during production of the product based on data defining carbon emissions per manufacturing weight of parts constituting the product. For example, the server 100 may calculate the amount of carbon emitted when the product is used based on data defining the average life span of the product and the amount of carbon emitted when the product is used. For example, the server 100 may calculate carbon emissions generated when the product is discarded based on data defining the carbon emissions per discarded weight of parts constituting the product. Since the calculation of carbon emissions generated during the production, use, and disposal of products has been described together with FIGS. 3 to 6, duplicate descriptions will be omitted.

The server 100 may determine the ratio of the first contribution to the determined carbon emissions as the first carbon reduction amount of the seller, and determine the ratio of the second contribution to the determined carbon emissions as the second carbon reduction amount of the buyer. .

According to another embodiment, in step S2030, the server 100 applies the contribution of each subject based on the 'use' carbon emissions (ex. 3000 tCO ₂ ) emitted by the use process of the item, and then each subject The amount of carbon savings saved can be calculated. For example, assuming the carbon emissions generated during production, use, and disposal of goods as the example of FIG. The amount obtained by adding the carbon emissions (ex. 1000 tCO ₂ ) generated when the product is disposed of can be determined as the seller's first carbon reduction amount (= 3000*1/3+1000 = 2000 tCO ₂ ). In addition, the amount obtained by adding the carbon emissions generated during the production of the product (10000 tCO ₂ ) to the carbon emissions at the rate of the second contribution (ex. 66.7%) to the used carbon emissions (ex. 3000 tCO ₂ ) is the buyer's second It can be determined by the amount of carbon savings (=3000*2/3+10000 = 12000 tCO ₂ ). In other words, the contribution of each entity is applied to the carbon emission of 'use', the seller calculates that all carbon emissions generated during the disposal of the product are reduced, and the buyer calculates that all carbon emissions generated during the production of the product are reduced is an example of

8 is an exemplary diagram for explaining an operation in which the server 100 determines a contribution between a seller, a buyer, and a relay entity based on a transaction price according to an embodiment.

Referring to FIG. 8 , in step S2020, the server 100 may additionally set a third contribution that the relaying entity providing a service for relaying used transactions has contributed to encouraging used transactions, which are carbon reduction means. For example, the relay price may include operating costs of the used transaction service of the relay entity for the total number of used transactions performed by the relay entity. For example, the brokerage price may include costs incurred in repairing the goods when the brokerage agent relays a used transaction for the goods. In FIG. 8, the server 100 calculates the used price (16,500 won) of the new price (10,000 won), the used transaction price (5,000 won), and the relay price (1,500 won) generated when the relay agent relays the used transaction. The ratio of the transaction price (5,000 won) is set as the first contribution (=30.3%), and the ratio of the new product price (10,000 won) to the sum price (16,500 won) is set as the second contribution (=60.7%), The ratio of the intermediate price (1,500 won) to the sum price (16,500 won) can be set as the third contribution (=9%).

Referring to FIG. 8 , in step S2030, the server 100 may additionally determine a third carbon reduction amount saved by the relay entity based on the third contribution contributed by the relay entity. When the carbon emission determined by the server 100 is 10000 tCO ₂ , the first contribution is 30.3%, the second contribution is 60.7%, and the third contribution is 9%, the server 100 determines the seller's first carbon reduction amount.

* 10000 = 3000 tCO ₂ , the buyer's second carbon savings

* 10000 = 6000 tCO ₂ , the third carbon reduction amount of the relaying subject

* It can be determined as 10000 = 1000 tCO ₂ .

After step S2030, the server 100 may aggregate revenue generated based on used transaction data, and distribute some of the determined revenue to each subject based on the contribution of each subject or the amount of carbon savings. For example, the server 100 may aggregate revenue generated by performing a revenue generation event based on used transaction data, and distribute the revenue according to the contribution of each entity. For example, a revenue-generating event includes the act of generating revenue from the proof data itself, or the act of generating revenue by acquiring carbon credits through proof data and then selling the carbon credits through an emission trading market or an emission trading certification body. can do.

According to the above-described embodiment, it is possible to objectively calculate the contribution to carbon emissions saved by an entity participating in a used transaction based on the transaction time or the transaction price. In addition, the entity that performed the used transaction can receive compensation by recognizing the carbon reduction efforts through the used transaction as carbon credits. As such, the embodiments of this document make it possible to actively operate an incentive system according to the reduction of carbon emissions that actively responds to government policies and the needs of the times.
