What are the minimum requirements for footprint verification?

All participation levels require that airports obtain independent third party verification of
their carbon footprint from a third party that is suitably qualified to perform the
verification.  

Verification principles to consider include:
  • Impartiality
  • Competence 
  • Factual approach to decision making 
  • Openness
  • Confidentiality 

The minimum requirements for airport footprint verification and the use of verification 
bodies are listed below. The Application Assessment Form contains a section in which
the verifier is required to confirm that these requirements have been fulfilled. The airport
may also wish and is encouraged to submit a brief ‘verification report’ as further
documentary evidence. The verification process should be conducted in accordance with
the requirements of ISO14064:3:
  • The verifier or verification body should be independent of the airport.
  • The verifier or verification body should not have assisted in any way with the development of the carbon footprint as this would constitute a breach of independence. 
The verification report should contain:
  • A statement verifying that the scope defined by the airport is compliant with the GHG protocol and the requirements of Airport Carbon Accreditation.
  • Confirmation that the verifier has concluded under a ‘reasonable level of assurance’ as defined in ISO14064:3  that the GHG footprint: 
    • is materially correct
    • is a fair representation of the GHG data and information
    • is prepared in accordance with the requirements of this programme, GHG protocol and ISO14064:1 (note currently only reporting on CO2 is required as mandatory for this programme)
