Which emission factors are used for each reporting section?

Emission factors are standard values used to estimate the amount of greenhouse gas (GHG) emissions associated with a specific activity, product, or process. They serve as essential tools in carbon accounting by linking actions—such as driving a vehicle or using electricity—to their climate impact, enabling organizations to calculate and track their emissions accurately.

At Compera, we use a combination of open-source and licensed databases to provide reliable and up-to-date emission factors for different emission scopes:

• Scope 1: We use emission factors from the UK’s Department for Energy Security and Net Zero (DEFRA). These are regularly updated, with the most recent dataset from 2024.
• Scope 2: For electricity-related emissions, we apply different sources depending on the reporting method:
  • Location-based: Data is sourced from the International Energy Agency (IEA).
  • Market-based: We refer to the Association of Issuing Bodies (AIB) database.
• District heating: Emission factors are sourced from Norsk Fjernvarme.

By using trusted sources, we help organizations make informed decisions and meet reporting standards with confidence.
