Emission factor databases of waste data

Hi all,

We’re currently reviewing our approach to emission factors and would really value your input.

  • Which emission factor database do you prefer — ADEME or UK Gov (= preferred source)? We’ve noticed significant discrepancies between the two.
  • How do you handle waste data for non-European sites? Is there a preferred or widely accepted database in such cases?
  • CAD transitioned from ADEME to the UK Gov database some time ago. However, older projects still rely on ADEME data. Would you recommend retrospectively updating these to maintain consistency?
  • More broadly: how do you typically approach waste data in your footprinting exercises?

Any insights or experiences you’d be happy to share would be greatly appreciated.

Kind regards
