Simplified data versions
We have simplified how we talk about and accept data versions based on user feedback. The
12.12 version format still works and is equivalent to the new fixed version format 12.Data Added
This data release introduces:
- The 2024 GHG Emission Factors Hub dataset, published by EPA, which covers emission factors data across the transportation, energy, and waste sectors.
- We added two datasets of spend-based emission data for New Zealand, sourced from Market Economics Limited.
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.
Data Removed
No data has been removed in this release.
