| 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) |

EXIOBASE
EXIOBASE is a global, detailed Multi-Regional Environmentally Extended Supply-Use Table (MR-SUT) and Input-Output Table (MR-IOT). It was developed by harmonising and detailing supply-use tables for a large number of countries, estimating emissions and resource extractions by industry. Subsequently, the country supply-use tables were linked via trade creating an MR-SUT and producing MR-IOTs from this. The MR-IOT can be used for the analysis of the environmental impacts associated with the final consumption of product groups. The EXIOBASE emission factors use basic prices. The basic price represents the initial cost set by a producer for a product or service, without additional fees like taxes or delivery costs (referred to as tax and transport margins). The values in the Climatiq Database might not be exactly the same as the ones you find on the EXIOBASE download page due to the prices used.

CBAM
The European Union's Carbon Border Adjustment Mechanism (CBAM) is a regulatory tool designed to measure carbon emissions attributed to the production of high-carbon goods imported into the EU, aiming to promote cleaner practices in industrial production across non-EU countries. To this end, the European Commission publishes emission factors providing the necessary metrics for compliance and environmental integrity.
