  • Co2emissiefactoren (Netherlands): Provides localized, activity-based emission factors tailored for operations in the Netherlands.

  • ADEME (France): Offers robust data for both spend-based and activity-based calculations, known for its focus on sustainability.

  • DEFRA (UK): The UK’s Department for Environment, Food & Rural Affairs supplies emission factors for various greenhouse gas activities.

  • BEIS (UK): A British government source offering energy-related emission data linked to sustainable growth.

  • EPA (USA): The Environmental Protection Agency provides updated default emission factors used widely in organizational GHG reporting.

  • EXIOBASE: A global database developed by university researchers, detailing emissions across economic sectors.

  • UNFCCC: The United Nations Framework Convention on Climate Change provides internationally recognized standards and data for emissions tracking.

Additional data enhancements

Whenever possible, we incorporate vendor-specific emission data to increase precision. Our in-house climate research team also monitors academic literature and public data releases to ensure we’re using the most up-to-date and relevant datasets available.

By combining global standards with localized and vendor-specific data, we ensure your emissions reporting is both accurate and tailored to your business needs.
