The aggregation unit 210 of the information processing server 2 aggregates the predicted CO2 emissions for each type of energy of the user in the aggregation period received by the reception unit 201 on a monthly basis.

(Step S204)
The transmission unit 202 of the information processing server 2 transmits the predicted CO2 emissions aggregated by the aggregation unit 210 for each type of energy to the user terminal 3 via the network 6. The information transmitted from the information processing server 2 is received by the receiving unit 301 of the user terminal 3 and displayed on the display device 300D by the display device control unit 305 (see FIG. 10).

(CO2 emission estimation process)
FIG. 11 is a flowchart showing an example of CO2 emission estimation processing (demand forecast processing) of the information processing system 1. Hereinafter, an example of the CO2 emission estimation process of the information processing system 1 will be described with reference to FIG.

(Step S301)
The estimation unit 207 of the information processing server 2 refers to the actual CO2 emission storage DB4 and acquires the actual usage amount for each type of energy of each user.

(Step S302)
The estimation unit 207 of the information processing server 2 refers to the user DB 1 and refers to the state of the occupancy of each user. Here, the state of the place of residence is the floor (number of floors) of the building to move in, the area to move in within the floor, the age of the building to move in, the size of the room to move in (square meters), and the like. Next, the estimation unit 207 corrects the actual usage amount for each type of energy acquired in step S301 based on the acquired state of the user's occupancy. For example, the estimation unit 207 corrects by multiplying the correction coefficient prepared in advance for each state of the occupancy by the actual usage amount for each type of energy acquired in step S301. The actual amount of energy used for each type of energy after correction in S302 is also described as the first estimated value. Further, the correction method is not limited to the method described here, and other methods may be used for correction. If there is no actual value, use the actual value of the company (tenant) closest to the place of residence (number of floors, orientation, size, age, etc.) within the specified range (for example, within ± 10%). You may. In this case, it is preferable to use the actual values of companies (tenants) in the same area.

(Step S303)
The estimation unit 207 of the information processing server 2 refers to the weather DB 3 and acquires the weather forecast information (the average temperature in the area). Next, the estimation unit 207 further corrects the first estimated value based on the acquired weather forecast information. For example, the estimation unit 207 further corrects by multiplying the first estimated value by a correction coefficient prepared in advance for each weather forecast information. For example, if the average temperature in the forecast is lower than the actual temperature (for example, the same day of the previous year on the forecast date), the correction factor to be multiplied is made larger than 1 because it is considered that electricity, city gas, and heavy oil will be used more. Since it is considered that there is little water, the correction coefficient to be multiplied is made smaller than 1. Also, if the average temperature in the forecast is higher than the actual one (for example, on the same day of the previous year on the forecast date), the correction coefficient to be multiplied is made larger than 1 because it is considered that more water will be used, while electricity, city gas, etc. Since it is considered that the amount of heavy oil is small, the correction coefficient for multiplication may be made smaller than 1. The second estimated value calculated by the estimation unit 207 is stored in the predicted CO2 emission storage DB 5 of the storage device 200B in association with the tenant ID. The first estimated value after correction in S303 is also described as the second estimated value. Further, the correction method is not limited to the method described here, and other methods may be used for correction.

(Step S304)
The calculation unit 208 of the information processing server 2 multiplies the second estimated value for each energy type by the emission factor to calculate the predicted CO2 emission amount for each energy type. The predicted CO2 emission amount calculated by the calculation unit 208 is stored in the predicted CO2 emission amount storage DB 5 of the storage device 200B in association with the tenant ID.

The CO2 emissions totaled by the predicted CO2 emission totaling process of FIG. 9 are automatically input to the required credit amount 1011 of FIG. 13, and the user can use the automatically input CO2 emissions as needed. The configuration may be changed.

(Step S402)
The selection unit 206 of the information processing server 2 refers to the emission credit selection DB 6 and extracts information on the CO2 emission credit of the trading market selected in step S402. Specifically, the selection unit 206 extracts information on domestic CO2 emission rights when condition 11 is selected, and when condition 12 is selected, the trading market is overseas CO2 emission rights. If condition 13 is selected, the trading market extracts information on both domestic and overseas CO2 emission rights.

(Step S403)
The selection unit 206 of the information processing server 2 determines whether the condition received in step S401 is whether the rank of the CO2 emission credit is prioritized, in other words, whether the rank of the CO2 emission credit is prioritized or the amount is prioritized. If the rank has priority (YES), the selection unit 206 executes the process of step S404. If the rank is not prioritized (NO), in other words, if the amount is prioritized, the selection unit 206 executes the process of step S405.

(Step S404)
The selection unit 206 of the information processing server 2 sorts (arranges) the CO2 emission credit information extracted in step S402 according to the rank condition received in step S401. Specifically, the selection unit 206 sorts the market rank values in descending order when the condition 21 is selected, and the market rank values are in ascending order when the condition 22 is selected. When condition 23 is selected, the type rank values are sorted in descending order, and when condition 24 is selected, the type rank values are sorted in ascending order, and condition 25 If is selected, the total rank values are sorted in descending order, and if condition 26 is selected, the total rank values are sorted in ascending order.

(Step S405)
The selection unit 206 of the information processing server 2 sorts the information of the CO2 emission right extracted in step S402 so that the unit price is in ascending order and the maximum transaction volume is in descending order. Specifically, the selection unit 206 sorts the unit prices in ascending order, and then sorts the maximum transaction volume in descending order with respect to the execution result. As a result, when there are multiple CO2 emission credits with the same unit price, multiple CO2 emission credits with the same unit price will be lined up when sorted in ascending order of unit price, and by sorting the maximum transaction volume in descending order, the unit price will be the same. Multiple CO2 emission credits are sorted so that the maximum trading volume is in descending order.

For example, when the selection unit 206 sorts a plurality of CO2 emission credits (credits A to D) so that the unit prices are in ascending order, the CO2 emission credits are arranged as follows.
Credit A Unit price: 300 yen Maximum transaction volume: 200
Credit B Unit price: 300 yen Maximum transaction volume: 300
Credit C Unit price: 300 yen Maximum transaction volume: 100
Credit D Unit price: 500 yen Maximum transaction volume: 200

Next, the selection unit 206 sorts the credits A to C having the same unit price so that the maximum transaction volume is in descending order, so that the CO2 emission credits are arranged as follows.
Credit B Unit price: 300 yen Maximum transaction volume: 300
Credit A Unit price: 300 yen Maximum transaction volume: 200
Credit C Unit price: 300 yen Maximum transaction volume: 100
Credit D Unit price: 500 yen Maximum transaction volume: 200

As described above, by sorting the unit price in ascending order and then sorting the maximum trading volume in descending order with respect to the execution result, the CO2 emission credits are arranged in ascending order of the unit price, and there are multiple CO2 emission credits with the same unit price. CO2 emission credits are arranged in descending order of maximum trading volume within the same unit price.

The selection unit 206 of the information processing server 2 calculates the procurement amount (procureable amount) that can be procured with the CO2 emission credit extracted in step S406. Specifically, the selection unit 206 acquires the information of the first line of the CO2 emission credits sorted in step S405 or step S406 and performs the following processing.
(1) When only the required credit amount is specified The maximum value that is equal to or less than the CO2 emission credit remaining amount (credit remaining amount), is equal to or greater than the minimum transaction amount, and is less than or equal to the maximum transaction amount is set as the procurement amount.
(2) When only the budget is specified
The maximum value of the budget balance ÷ unit price rounded off, the minimum transaction volume or more, and the maximum transaction volume or less is the procurement amount.
(3) When both the budget and the required credit amount are specified The procurement amount shall be the smaller of the above two values.

The “procurement amount” is the amount of CO2 emission credits that can be procured for each sorted CO2 emission credit (see “Procurement amount” in FIG. 14).
The "budget balance" is a value obtained by subtracting the "unit price" x "maximum transaction volume" of the "CO2 emission credit (credit)" from the designated "budget amount" (budget amount 1012 in FIG. 13).
Specifically, the budget balance of the first CO2 emission credit (the first CO2 emission credit after sorting) is expressed by the following equation (1).
"Budget balance" = "Specified budget amount"-"Unit price" x "Maximum transaction volume" ... (1)
In addition, the budget balance of the second and subsequent CO2 emission credits (the second CO2 emission credit after sorting) is expressed by the following equation (2).
"Budget balance" = "Budget balance of previous processing (first case)"-"Unit price" x "Maximum transaction volume" ... (2)

Further, in the description of step S407 above,
The "CO2 emission right remaining amount (credit remaining amount)" is obtained by subtracting the "procurement amount" calculated in the "emission right credit record" from the specified "required credit amount" (required credit amount 1011 in FIG. 13). The value.
Specifically, the remaining amount of CO2 emission credit of the first case (the first CO2 emission credit after sorting) is expressed by the following equation (3).
"CO2 emission credit (remaining credit amount)" = "Required credit amount entered"-"Procurement amount" ... (3)
The remaining amount of CO2 emission credits after the second case (second CO2 emission credits after sorting) is expressed by the following equation (4).
