As part of our ongoing commitment to providing you with the most accurate and up-to-date emissions, we’re updating the way we calculate Scope 3 Category 3 (S3C3) emissions. Since your organisation has S3C3 emissions for 2025, we want to let you know that the calculation methodology will change on December 9th.
What is Scope 3 Category 3?
Fuel- and energy-related activities (Scope 3 Category 3) include all emissions associated with the production, transmission, and distribution of the fuels and energy your organisation purchases and consumes. While Scope 1 covers emissions from fuel combustion, and Scope 2 covers emissions from purchased energy generation, Scope 3 Category 3 captures the entire lifecycle of fuels and energy beyond direct use.
What’s changing?
Starting December 9th, our methodology for calculating S3C3 emissions from purchased energy will use a location-based emission factor for all energy types, including renewable. This will provide results that are more accurate and aligned with consistent location-based reporting.
What’s the impact?
On average, this update results in an approximate 0.29% decrease in total reported emissions across all customers. The change will not be applied retroactively. Any new 2025 activity data added after December 9th will be calculated using the updated formula to ensure ongoing accuracy. If you wish to reprocess your historical emissions, please note recalculations for 2024 and 2025 will utilise the new electricity emissions factors released in June and November.
