Temporal Relevance

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.
