In the above-described first to third embodiments, the example in which the CO ₂ emission amount is calculated by multiplying the CO ₂ emission basic unit and the heat consumption rate H has been shown. However, in the fourth embodiment, further, By changing the value of CO ₂ emission basic unit in the calculation, basic unit data corresponding to individual generator characteristics is formed for the same fuel type. Specifically, by giving a weighting factor to each CO ₂ emission basic unit, basic unit data corresponding to individual generator characteristics is formed. For example, the generator has a long (old) generator operating period, and the weighting factor is increased, or the weighting factor is decreased during a time period in which the CO ₂ emission amount decreases during the day.

That is, the third calculation function provided in the above-described CO ₂ emission calculation units 31, 32,..., 3n is based on the CO ₂ emission basic unit of each generator stored in the basic unit data storage unit 12.

FIG. 16 is a diagram showing an example of a screen showing the CO ₂ emission amount in the past certain period in a tabular format together with weight coefficient data for each generator.

In the table of the figure, in addition to the various items shown in the table of FIG. 10 described above, an item “weighting factor” is added in the vertical direction of the table, and a time column is displayed in the data column corresponding to the item. Each weighting factor is displayed. For example, the weighting factor is made small during the time period when the CO ₂ emission amount decreases during the day.

In this case as well, the total value or average value of the CO ₂ emission amount for each generator may be further displayed, and the integrated value of the CO ₂ emission amount for the past 24 hours may be further displayed. May be. Similarly to the case of FIG. 7 described above, data may be displayed not for each generator but for each fuel type (or for each CO ₂ emission basic unit). Further, in order to capture the CO ₂ emission amount based on the past performance, it is desirable that the period to be displayed can be freely set by the operator if it is past from the present.

As a result, the weighting factor set for each time can be grasped, and the CO ₂ emission amount of the past fixed period with high accuracy adjusted by the weighting factor for each time, the total value, and the average value thereof. It is possible to grasp the state that has changed.

(A) to (g) of FIG. 17 is a diagram showing an example of a bar graph for each generator, with “time” in FIG. 16 on the horizontal axis and “CO ₂ emission” on the vertical axis. is there.

As shown in the figure, the hourly CO ₂ emission adjusted by the weighting coefficient is displayed in a bar shape. Thereby, it is possible to accurately grasp the state in which the CO ₂ emission amount has changed every hour.

In addition, for each generator, a screen showing the CO ₂ emission amount for a certain period in the future in a tabular format may be displayed together with the weight coefficient data. In this case, in addition to the various items shown in the table of FIG. 12, an item “weighting factor” is added in the horizontal direction of the table, and the weighting factor for each time is displayed in the data column corresponding to the item. Let For each generator, a screen with a bar graph with “time” on the horizontal axis and “CO ₂ emissions” on the vertical axis may be displayed.
