ADEME (Agence de la transition écologique) is the French Agency for Ecological Transition and offers a wide range of emission factors to support the measurement and reduction of greenhouse gas emissions in France. These emission factors are used to estimate greenhouse gas emissions associated with various activities, such as energy consumption and transportation.

The UK Government issues emission conversion factors for use by UK and international organisations to report on greenhouse gas emissions. The key responsible departments / agencies are / were: BEIS , DEFRA, DESNZ and NAEI.

ecoinvent is a Swiss not-for-profit association that provides a Life Cycle Inventory (LCI) database that supports various types of sustainability assessments. This data enables users to gain a deeper understanding of the environmental impacts of their products and services. ecoinvent provides multiple climate impact indicators. We use "IPCC 2007 (superseded), climate change, global warming potential (GWP100)" for AR4 CO2e emisison factor values and "IPCC 2013, climate change, global warming potential (GWP100)" for AR5 values.

Ember is an independent non-profit energy think tank that publishes open electricity emission factors, calculated by combining country-level power generation data with fuel-specific emissions coefficients to estimate total emissions and carbon intensity, as described in its methodology document: https://files.ember-energy.org/public-downloads/ember_electricity_data_methodology.pdf

Greenview is a sustainability platform that provides the Hotel Footprinting Tool, utilizing data from over 27,000 hotels in the Cornell Hotel Sustainability Benchmarking index.

The International Energy Agency (IEA) provides comprehensive electricity emission factors, which are essential for understanding the carbon footprint of electricity generation across different regions and energy sources. These factors assist governments, businesses, and researchers in measuring the environmental impact of electricity consumption and in developing strategies for reducing greenhouse gas emissions in the energy sector.
