Carbon Trust verification and assurance service allow organisations to report environmental claims and data with confidence and credibility.

GHG Footprint Verification is a third-party verification service, which provides an independent and impartial verification of an organisation’s carbon footprint over a given period of time.


We verify your organisational GHG footprint verification in accordance with the ISO 14064 methodology, which is the internationally accepted way of measuring organisational footprints. ISAE 3000 is the standard for assurance over non-financial information.

Verification allows you to communicate your environmental data with credibility.

This service may be useful if you:

  • are looking to publish details of your carbon footprint, e.g. in your annual report, environmental report or Carbon Disclosure Project submission and you require independent assurance of the accuracy of your data;
  • have been collecting footprint data but do not meet all the requirements which would enable you to seek certification under the Carbon Trust Standard;
  • are looking for independent assurance of other organisational footprint claims, such as the organisational footprint across different boundaries or across multiple years.
