  The basic unit calculation task 35 is a program for calculating a carbon dioxide emission amount (greenhouse gas amount) per unit power amount (unit energy) generated by generating power (generating electric power) every time unit. , 8 based on the flowchart shown in FIG.

  First, the total power generation amount for the first hour is calculated (step S1). That is, the power generation amount of each power generation unit G1 to Gn for the first hour is added to calculate the total power generation amount, and the result is added to the first time in the “hourly” column of the power generation amount database 32 (FIG. 4). Remember. Next, when the power generation amount for the next hour is stored in the power generation amount database 32 (“Y” in step S2), the total power generation amount for the next hour is calculated in the same manner as in step S1. The result is calculated, and the result is stored in the corresponding time in the “by hour” column of the power generation amount database 32 (step S3). Such calculation and storage are completed for all time data (power generation amount) (“N” in step S2).

  Subsequently, the total power generation amount for each day is calculated (step S4). That is, the total power generation amount (by hour) for each hour of the corresponding day is added to calculate the total power generation amount, and the result is stored in the corresponding day in the “daily” column of the power generation amount database 32. Such calculation and storage are performed for all days. Further, the total power generation amount for each month is calculated (step S5). That is, the total power generation amount (daily) of each month is added to calculate the total power generation amount, and the result is stored in the corresponding month in the “Monthly” column of the power generation amount database 32. Such calculation and storage are performed for all months.

  Next, the total discharge amount of carbon dioxide for the first hour is calculated (step S6). That is, the total emission amount is calculated by adding the carbon dioxide emission amounts of the power generation units G1 to Gn in the first hour, and the result is calculated as the first hourly column in the emission database 33 (FIG. 5). Remember in time. Next, when the discharge amount for the next hour is stored in the discharge amount database 33 (in the case of “Y” in step S7), the total discharge amount for the next hour is calculated in the same manner as in step S6. The result is calculated, and the result is stored in the corresponding time in the “by hour” column of the emission amount database 33 (step S8). Such calculation and storage are completed for all time data (discharge amount) (“N” in step S7).

  Subsequently, the total discharge amount of each day is calculated (step S9). That is, the total discharge amount (by hour) of each time on the corresponding day is added to calculate the total discharge amount, and the result is stored in the corresponding day in the “daily” column of the discharge amount database 33. Such calculation and storage are performed for all days. Further, the total emission amount for each month is calculated (step S10). That is, the total emission amount (by day) of each day of the corresponding month is added to calculate the total emission amount, and the result is stored in the corresponding month in the “Monthly” column of the emission amount database 33. Such calculation and storage are performed for all months.

  Next, the carbon dioxide emission amount per unit power amount for the first hour is calculated (step S11). That is, the total power generation amount for the first hour is obtained from the power generation amount database 32, the total emission amount for the first hour is obtained from the discharge amount database 33, and the total discharge amount is divided by the total power generation amount to obtain unit power. Calculate the amount of carbon dioxide emissions per unit (unit emissions). Then, the calculated emission intensity is stored at the first time in the “hourly” column of the intensity memory area 38 as shown in FIG. Next, when the total power generation amount and the total emission amount for the next one hour are stored in the databases 32 and 33 (in the case of “Y” in step S12), the same one hour as in step S11. The emission basic unit is calculated, and the result is stored in the corresponding time in the “by hour” column of the basic unit memory area 38 (step S13). Then, such calculation and storage are completed for all time data (total power generation amount and total emission amount) (“N” in step S12).

  Subsequently, a carbon dioxide emission amount per unit power amount of each day is calculated (step S14). That is, the emission amount of the corresponding day acquired from the emission amount database 33 is divided by the generation amount of the corresponding day acquired from the generation amount database 32 to calculate the carbon dioxide emission amount per unit power amount of the corresponding day. The result is stored on the corresponding day in the “daily” column of the basic unit memory area 38. Such calculation and storage are performed for all days. Further, a carbon dioxide emission amount per unit power amount for each month is calculated (step S15). That is, the emission amount of the corresponding month acquired from the emission amount database 33 is divided by the power generation amount of the corresponding month acquired from the power generation amount database 32 to calculate the carbon dioxide emission amount per unit power amount of the corresponding month. The result is stored in the corresponding month in the “Monthly” column of the basic unit memory area 38. Such calculation and storage are performed for all months.

  The emission amount calculation task 36 calculates the emission amount of carbon dioxide discharged by each customer C1 to Cn for each time unit on the basis of the carbon dioxide emission amount per unit power amount and the power consumption amount. It is a program and is based on the flowchart shown in FIG.

  First, the power consumption data of the first consumer C1 is acquired from the usage database 31 (step S21). Next, the carbon dioxide emission amount for the first hour is calculated (step S22). That is, the first one hour of used electric energy in the acquired used electric energy data (FIG. 3) and the carbon dioxide emission per unit electric energy of the first hour stored in the basic unit memory area 38 (FIG. 9). Multiply by (Emission intensity) to calculate carbon dioxide emissions. Then, the calculated emission amount is stored at the first time in the “by hour” column of this customer C1 in the emission amount memory area 39 as shown in FIG.

  Next, when the electric power consumption and emission basic unit for the next hour are stored in the usage amount database 31 and the basic unit memory area 38 respectively (in the case of “Y” in step S23), step S22 and Similarly, the carbon dioxide emission amount for the next hour is calculated, and the result is stored in the corresponding time in the “by hour” column of this consumer C1 in the emission amount memory area 39 (step S24). Such calculation and storage are completed for all time data (power consumption and emission intensity) ("N" in step S23).

  Subsequently, the carbon dioxide emission amount of each day of the first consumer C1 is calculated (step S25). That is, the carbon dioxide emission amount for each hour on the corresponding day is added, and the result is stored on the corresponding day in the “daily” column of this consumer C1 in the emission amount memory area 39. Such calculation and storage are performed for all days. Furthermore, the carbon dioxide emission amount of each month of the first consumer C1 is calculated (step S26). That is, the carbon dioxide emission amount of each time (each day) of the month is added, and the result is stored in the month of the “monthly” column of this consumer C1 in the emission memory area 39. Such calculation and storage are performed for all months.

  Next, it is determined whether or not the calculation for all the consumers C1 to Cn has been completed (step S27). If the calculation has not been completed, the power consumption data of the next consumer C2 to Cn is used as the usage amount database. 31 (step S28), and the process returns to step S22 to repeat the same processing.

  Next, the operation of the emission amount calculation system 1 having such a configuration and the calculation method of the greenhouse gas emission amount in this embodiment will be described based on the timing chart shown in FIG.

  First, the “power generation amount data” as described above is periodically transmitted from each of the power generation units G1 to Gn (for example, every hour) to the management computer 3 (step S31). The power generation amount for each hour is stored in the power generation units G1 to Gn (step S32). Further, when the “emission amount data” as described above is periodically transmitted from each power generation unit G1 to Gn to the management computer 3 (step S33), 1 is assigned to the corresponding power generation units G1 to Gn in the emission amount database 33. The discharge amount for each time is stored (step S34). On the other hand, when the “metering data” as described above is periodically transmitted from the power meter 2 of each customer C1 to Cn to the management computer 3 (step S35, consumption metering step), the corresponding data in the usage database 31 is obtained. The hourly power consumption is stored in the consumers C1 to Cn (step S36).

  Next, when it is time to calculate the greenhouse gas emission amount due to the power usage of each consumer C1 to Cn (for example, every three months), the basic unit calculation task 35 is activated (step S37), as described above. Thus, the carbon dioxide emission amount per unit power amount in this period is calculated (unit amount calculation step). Subsequently, the emission calculation task 36 is activated (step S38), and as described above, the amount of carbon dioxide emitted by each customer C1 to Cn during the current period is calculated (emission calculation). Step). The emission amount calculated in this way (for example, the total emission amount during the current period) is calculated for each customer C1 to C1 registered in advance as “Notification of Emissions” for each customer C1 to Cn. Or sent to Cn's email address.

  As described above, according to the emission amount calculation system 1 and the greenhouse gas emission calculation method, the electric power company G that supplies electric power calculates the carbon dioxide emission amount per unit electric energy, By simply measuring the amount of power used in Cn, it is possible to calculate the amount of carbon dioxide emitted by the power consumption of each consumer C1 to Cn. In other words, each customer C1 to Cn does not need to have a complicated configuration of equipment or system, it is only necessary to measure the amount of power used, and it is easy to calculate greenhouse gas emissions with a simple configuration. It becomes possible to do.

  In addition, for each time unit, that is, for every hour, the amount of carbon dioxide emitted per unit power is calculated, the amount of power used is measured, and the amount discharged is calculated every hour. For this reason, it becomes possible to calculate the more exact discharge | emission amount according to the electric power generation condition by each electric power generation unit G1-Gn and the electric power usage condition of each consumer C1-Cn.

  By the way, in this embodiment, only carbon dioxide is described as a representative greenhouse gas, but it is needless to say that other greenhouse gases such as methane and nitrogenated zinc can be handled in the same manner. That is, when calculating all greenhouse gas emissions, measure or calculate all greenhouse gas emissions in each of the power generation units G1 to Gn, and based on the total, What is necessary is just to calculate the amount of greenhouse gas emission by the consumers C1-Cn.

(Embodiment 2)

The system application 3A2 stores whether or not the consumers C1 to Cn are registered to receive the right to receive emission rights from the electric power company G. In the target value 3A3, when “registered” is stored in the system application 3A2, the annual target emission amount that the consumers C1 to Cn set in advance, that is, the upper limit target of the greenhouse gas amount to be emitted in one year is stored. The value is stored. Further, by the first transaction task 3B1 to be described later, the excess emission amount 3A4 is stored with the excess emission amount that exceeds the target emission amount, and the bill 3A5 has the beneficial interest corresponding to the excess emission amount. The amount charged (transfer fee) associated with the transfer is stored. It should be noted that a plurality of values, that is, values for a plurality of years can be stored in the excess discharge amount 3A4 and the charge amount 3A5.

The amount is calculated (step S42). That is, the annual emission amount is calculated by adding the emission amount stored in the “monthly” column of this consumer C1 in the emission amount memory area 39 for one year (for 12 months). Next, it is determined based on the system application 3A2 whether or not the customer C1 is registered to receive the beneficiary right of the emission right from the electric power company G (step S43). It is determined whether the annual emission amount calculated in S42 exceeds the annual target emission amount stored in the target value 3A3 (step S44). And when it is not registered (in the case of “N” in step S43), or when the annual target emission amount is not exceeded (in the case of “N” in step S44), the customer computer of this customer C1 4. Send (e-mail) an “emission notification” message with the annual emission amount as information content (step S45).

  On the other hand, if it is registered (in the case of “Y” in step S43) and exceeds the annual target emission amount (in the case of “Y” in step S44), the invoice amount associated with the transfer of the beneficial interest is calculated. (Step S46). That is, an excess emission amount is calculated by subtracting the annual target emission amount from the annual emission amount calculated in step S42, and this excess emission amount is multiplied by a predetermined transfer amount per unit emission amount to obtain a billed amount. calculate. Then, the calculated excess discharge amount and the billed amount are stored in the excess discharge amount 3A4 and the billed amount 3A5, respectively. Subsequently, a “transaction confirmation” message is sent to the customer computer 4 of the customer C1 with the information on the annual emission amount, the excess emission amount, the billing amount, and the inquiry confirming the transfer of the beneficial interest (step S47). .

  Next, it is determined whether or not the processing for all of the consumers C1 to Cn has been completed (step S48). If the processing has not been completed, information on the next consumer C2 to Cn is acquired from the transaction database 3A. (Step S49), returning to Step S42, the same processing is repeated.

  The second transaction task 3B2 is activated when a reply message to the “transaction confirmation” is received from the customer computers 4 of the consumers C1 to Cn. First, as shown in FIG. Information is acquired from the transaction database 3A (step S51). When the reply message is a “transaction approval” message indicating that the beneficiary right is to be transferred (“Y” in step S52), a “transfer instruction” message is transmitted to the transaction computer 5 of the trust bank T. Here, in the “transfer instruction” message, the identification information of the consumers C1 to Cn, the excess emission amount stored in the excess emission amount 3A4, and the beneficiary right corresponding to the excess emission amount are given to the customer C1. To transfer to Cn. On the other hand, when the reply message is a “no transaction” message indicating that the beneficiary right is not transferred (in the case of “N” in step S52), the data of the billed amount 3A5 of the consumers C1 to Cn is cleared ( Step S54).

  When the customer computer 4 receives the “transaction confirmation” message from the management computer 3, the customer computer 4 transmits a “transaction approval” message or a “transaction unnecessary” message to the management computer 3 in accordance with the input instruction or by an automatic reply program. It has a function. Further, when the transaction computer 5 receives the “transfer order” message from the management computer 3, the transaction computer 5 assigns a beneficiary right corresponding to the excess emission amount from the emission right entrusted by the electric power company G to the designated customer. It has a task to perform a transfer process of transferring to C1 to Cn (transferring the beneficial interest to the accounts of the consumers C1 to Cn).

  Next, the operation of the emission trading system 10 having such a configuration and the greenhouse gas emission trading system in this embodiment will be described based on the timing chart shown in FIG. Here, since this system 10 is provided with the emission amount calculation system 1 of the first embodiment as described above, the emission amount of carbon dioxide emitted by each customer C1 to Cn by use of electric power is calculated. The result is stored in the discharge amount memory area 39 of the management computer 3. In this state, the first transaction task 3B1 of the management computer 3 is activated at a specific period of one year (for example, at the end of the fiscal year) (step S61). If the registration is received from G and the annual emission exceeds the annual target emission, a “confirm transaction” message is transmitted to the customer computer 4 of the customer C1 to Cn (step S62). On the other hand, if the beneficiary rights are not registered, or if the annual emissions do not exceed the annual target emissions, an “emission notification” message will be displayed on the customer computers 4 of the consumers C1 to Cn. It is transmitted (step S63).

  Subsequently, when the management computer 3 receives the “transaction approval” message from the customer computers 4 of the consumers C1 to Cn who have transmitted the “transaction confirmation” message (step S64), the second transaction task 3B2 is activated ( In step S65, as described above, the “transfer instruction” message is transmitted to the transaction computer 5 of the trust bank T (step S66). Then, by the above-described task of the trading computer 5, a transfer process is performed to transfer the beneficiary rights of the power company G corresponding to the specified excess emission amount to the specified consumers C1 to Cn (Step S67, beneficiary rights transfer). Step). On the other hand, the second transaction task 3B2 is also activated when the management computer 3 receives a “transaction unnecessary” message from the customer computers 4 of the consumers C1 to Cn who have transmitted the “transaction confirmation” message (step S68). In step S69), as described above, the corresponding billing amount 3A5 in the transaction database 3A is cleared.

  As described above, according to the emission trading system 10 and the greenhouse gas emission trading method, the amount of greenhouse gas emitted by the consumers C1 to Cn is calculated in the power company G that owns the emission credit, Further, when the emission amount exceeds the target emission amount of the consumers C1 to Cn, the beneficiary right of the emission right is transferred to the consumers C1 to Cn. In other words, the consumers C1 to Cn are discharged from the electric power company G when the emission amount exceeds the target emission amount without setting up and operating complicated facilities and systems or performing complicated processing. You can receive a beneficiary right. In this way, it is possible to easily trade greenhouse gas emission rights with a simple configuration. In addition, since the “transfer order” message for transferring the beneficiary right corresponding to the excess emissions to the consumers C1 to Cn is transmitted to the transaction computer 5 of the trust bank T, the customers C1 to Cn respond to the excess emissions. Receive appropriate beneficiary rights. Furthermore, by using the trust system of the existing trust bank T, for example, it is possible to smoothly trade emission rights (beneficial rights) by using existing systems and tasks that perform the transfer process as described above. It becomes possible.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in the first embodiment, the emission calculation task (emission calculation means) 36 is provided in the management computer 3 of the electric power company G, but may be provided in the computers of the consumers C1 to Cn or other organizations. The computer may be provided. In the above embodiment, the case where the energy that is the source of the greenhouse gas is electric power has been described. However, it is needless to say that the present invention can be applied to other energy such as gas and light oil. For example, in the case of gas, a greenhouse gas amount per unit gas amount generated by consuming gas is calculated in a gas company supplying the gas. On the other hand, the consumption of gas by the consumers C1 to Cn is measured, and based on the calculated greenhouse gas amount per unit gas amount and the measured consumption, the greenhouse discharged by the gas consumption of the consumers C1 to Cn Calculate the amount of effect gas emissions. Furthermore, when the calculated emission amount exceeds the target emission amount of the consumers C1 to Cn, the beneficiary rights of the gas company's emission rights are transferred to the consumers C1 to Cn.
