Data Added

Data Changed

This list only covers major changes. Changes covering a smaller subset of emission factors, or changes such as name or description changes, are not listed. Find a link at the end of this document to a structured table listing all changes.

• We updated the 2019 BEIS spend-based CO2e emission factors values based on the latest dataset "UK full dataset 1990 - 2020 including conversion factors by SIC code".
• We corrected the year valid for electricity data from the eGrid and GHG Emission Factors Hub datasets, which are published by EPA.
• We combined emission factors for mobile combustion activities (CO2 data from Table 2 with CH4 and N2O data from Table 5) from the EPA's 2023 GHG Emission Factors Hub dataset to calculate a total CO2-equivalent value.
