Calculate Scope 1, Scope 2 and Scope 3 greenhouse gas emissions using documented emission factors and activity data. Enter the company and reporting period, choose the country, then select the factor through its category and Level 1 / Level 2 / Level 3 hierarchy. Scope is determined automatically from the selected factor.
1 · Company & reporting period
Enter the company information and reporting period first. The reporting year used for factor availability is derived from the reporting period end date.
The reporting period belongs to the company inventory. Factor Source Year remains the original publication/data year of the selected emission factor and is not relabelled.
2 · Select factor & activity data
Search all factors or drill down through Category, Level 1, Level 2, Level 3 and further levels where available. Scope is not manually selected; it comes from the verified factor.
