Gathering the approved inventory's figures…
Your carbon work
Your organization's greenhouse gas inventory under ISO 14064-1, one per reporting period. You fill one workbook — the purpose, your facilities, your sources and your activity data with the invoice or meter reading each came from — and the inventory is calculated from it with the emission factors you chose, shown by ISO 14064-1 category and by GHG Protocol scope together. Once your approver approves it the figures freeze, and a later year is compared with them.
This year so far · January to October 2026
Provisional: not approvedFrom the readings recorded in the 2026 inventory so far, calculated as the inventory calculates. The year is approved, and its figures frozen, once it is complete.
35 rows of 2025 cover more than these months (a whole year on one invoice), so they are not divided into months and not in the 2025 figure above. Recording by the month makes the comparison whole.
No reading recorded for September from these sources:
AC-1 Office and control-room split units (R-410A) · CHL-1 Process water chiller (HFC-134a)
This year, month by month
Each month's readings so far against the same month of the year before. They are not approved, and nothing here is calculated differently from the inventory.
