7.5REPORTING ON EMISSIONS REDUCTIONS FROM STAKEHOLDER ENGAGEMENT INITIATIVES When an airport has been accredited for three or more years at Level 3/3+, it may choose to move from an annual to a three-yearly renewal cycle. In order to do so, the airport must be able to demonstrate quantified scope 3 emissions reductions as a result of stakeholder engagement at the airport. The emissions reduction achieved should be reported as follows: -
The airport should provide a description of the emissions reduction initiative, its role in the initiative and the specific stakeholders involved.
-
The airport should provide a figure for the scope 3 emissions reduction that has been achieved against a baseline ‘business as usual’ scenario, i.e. by comparing it with what would have happened in the absence of the emissions reduction initiative.
-
Emissions reductions should be reported in tCO2/year or tCO2-e/year and should be verified.
-
An emissions improvement metric should be identified (absolute or relative emissions reductions) (see section 7.14 for further guidance)
-
The scope 3 emissions reductions must have arisen as a result of an emissions reduction initiative in which the airport has played a significant role. Section 12.3 contains examples of how an airport may seek achieve emissions reductions from scope 3 sources.
-
The airport can choose to provide details of initiatives for any emissions source that it can guide or influence, and is not limited to the mandatory scope 3 emissions sources that must be reported at Level 3/3+.
On provision of the information above, the airport’s Accreditation will be valid for 3 years, however the airport must also continue to provide carbon footprint data to the Administrator on an annual basis. Failure to do so will lead to the airport’s omission from the Airport Carbon Accreditation Annual Report for that participation year.
7.6Other Greenhouse Gases Airport Carbon Accreditation focuses only on carbon dioxide (CO2). This is to keep the carbon accounting simple in the early years of the programme. It is recognised, however, that there are other greenhouse gases (see the footnote in section 2). If a participating airport wishes to calculate its footprint to include more than just carbon dioxide emissions then it should report its overall carbon footprint in terms of tonnes carbon dioxide equivalent (CO2e).
Verification provides confidence and credibility to the airport’s claims
Verification of the Carbon Footprint
7.7Why Verify? Verification of the carbon footprint is a requirement for all levels of Airport Carbon Accreditation.
The primary aim of verification is to provide confidence to users that the reported information and associated statements represent a faithful, true, and fair account of a company’s GHG emissions.
Ensuring transparency and verifiability of the inventory data is crucial for verification. The more transparent, well controlled and well documented a company’s emissions data and systems are, the easier it will be to verify.
Verification is required by an independent third party
7.8Verification Process
The verification process typically involves the analysis of the methodology, data collection techniques and the calculation process that was used for developing the carbon footprint.
The programme requires that an airport’s carbon footprint is formally verified by an independent third party. This applies to Scope 1 and 2 emissions at Levels 1 or 2 and Scope 3 emissions at Levels 3 or 3+ although it is accepted that access to the source documents to verify data for Scope 3 emissions might not be possible, for example where a third party considers those documents to be commercially sensitive.
At levels 2 and above, an airport must provide supporting evidence for the information provided in the application form to demonstrate that the carbon management plan (and at level 3 and above, the stakeholder engagement plan) has been implemented effectively. Where this evidence is not available in English, the verifier must also confirm that this has been reviewed in the spaces provided on the Application Assessment Form.
Airports should note that a third party verifier will charge for verification services in most cases. These charges are separate to the programme application/participation fees and will be payable directly to the third party verifier and not to the Administrator. The Administrator cannot verify a carbon footprint as this would introduce a potential conflict of interest.
7.9Verification schedule
Airports are required to submit a verified carbon footprint on their initial application, and every second year subsequently for the level for which they are accredited. Airports participating at Level 3 or 3+ on a three-year renewal cycle are required to submit verified data every third year.
If an airport upgrades from one level to another, they must submit a verified carbon footprint, regardless of whether or not the previous year’s footprint was verified. Furthermore, an airport entering at or upgrading to Level 2 and beyond shall also have to verify the chosen base year against which its target is set (at least for Scope 1 and 2 emissions). This is demonstrated in the table below:
Year | Airport A | Airport B | Airport C | Year 1 | Apply Level 1 | Apply Level 1 Verification required for Year 0 footprint | Renew Level 3/3+ Verification required for Year 0 footprint | Year 2 | Renew Level 1 Verification not required for Year 1 footprint | Upgrade Level 2 Verification required for Year 1 footprint as well as for the chosen base year (at least for Scope 1 & 2). | No renewal required Submission of non-verified carbon footprint data to Administrator | Year 3 | Renew Level 1 Verification required for Year 2 footprint |
Renew Level 2
Verification not required for Year 2 footprint
|
No renewal required
Submission of non-verified carbon footprint data to Administrator
| Year 4 | Renew Level 1 Verification not required for Year 3 footprint | Renew Level 2 Verification required for Year 3 footprint | Renew Level 3/3+ Verification required for Year 3 footprint |
