How to correctly cite these factors in your GHG Footprint Reporting Methodology:-
Department for Environment Food & Rural Affairs. (2024) Supply chain emission factors for spending on products [Online]. Available at https://carbonsaver.org/tools/carbon_factors_database.php (Accessed ).
The 2024 factors are based on the latest UK Footprint data published by DEFRA in 2024. Please note that DEFRA has a 3 year time lag producing the data, ie. 2024 factors are actually based on the 2021 UK Government Footprint Data, etc.
It is common to have a time lag in emissions factors, eg. the BEIS UK Government Grid Electricity factor for 2023 is actually based on emissions data from 2021.
