| Methodology description | The dataset contains many different types of emission factors (fuels, electricity, travel, freight for example) and publishes a detailed methodological guide for each type. See https://www.gov.uk/government/publications/greenhouse-gas-reporting-conversion-factors-2025 . The emission factors undergo a peer review process prior to their publication each year. The source also provides a "major changes" document that lists all significant year-on-year changes in emission factors and explains them. The emission factors have been published each year for over 20 years and are generally considered to be high quality. They continue to be used globally and are adopted by other governments (e.g. USA, New Zealand) although there is a trend towards using more local emission factors as more governments publish them. Emission factors use GWPs from AR5 except for bioenergy, hotel stays, and material use emission factors that use AR4. As CO2 tends to dominate emissions this is unlikely to make a signficant difference. Climatiq has extracted emissions factors from the following flat file: Conversion factors 2025: full set (for advanced users) |
