Airports are at different points on the journey to becoming cleaner and more efficient. As the centrepoints of a complex web of aircraft movements, technical operations and surface access transport, airports can address their CO2 emissions in a variety of ways. These can include better insulation and energy efficiency, switching to green energy sources, investing in hybrid, electric or gas-powered service vehicles, encouraging employees, passengers & visitors to use public transport, working with airlines & air traffic management to reduce runway taxiing times and implement green landing processes and much more.
That’s why Airport Carbon Accreditation has 4 levels of certification.
To apply for certification at one of the 4 levels of the programme, airports must have their carbon footprints independently verified in accordance with ISO14064 (Greenhouse Gas Accounting). Evidence of this must be provided to the administrator together with all claims regarding carbon management processes which must also be independently verified.
The definitions of emissions footprints used by Airport Carbon Accreditation follow the principles of the World Business Council for Sustainable Development (WBCSD) and the World Resources Institute (WRI) “Greenhouse Gas Protocol” Corporate Accounting and Reporting Standard. When considering the emissions from aircraft within the airport perimeter and on final approach and initial departure, Airport Carbon Accreditation uses the International Civil Aviation Organisation’s (ICAO) definition of the Landing-Take Off cycle and requires airports to comply with these definitions.
