What is it?

Airport Carbon Accreditation is the only institutionally-endorsed, global carbon management certification programme for airports. It independently assesses and recognises the efforts of airports to manage and reduce their carbon emissions through 7 levels of certification: ‘Mapping’, ‘Reduction’, ‘Optimisation’, ‘Neutrality’, ‘Transformation’, ‘Transition’ and ‘Level 5’.

Through its 7 levels of certification, Airport Carbon Accreditation acknowledges that airports are at different stages in their journey towards comprehensive carbon management. It is a programme for airports of all sizes, extending beyond hubs and regional airports with scheduled passenger traffic, to include general aviation and freight-focused airports.

Who’s behind it?

Airport Carbon Accreditation is owned and governed by ACI EUROPE in close cooperation with four ACI regions and with support of ACI World. The programme is administered by WSP, the environmental consultancy tasked with enforcing the strict criteria of accreditation and safeguarding the independent character of the programme’s framework.

How does it work?

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 renewable gas-powered service vehicles, encouraging employees, passengers and visitors to use public transport, working with airlines and air traffic management to reduce runway taxiing times and implement green landing processes and much more.

The 7 levels of accreditation

The programme provides a unique common framework and tool for active carbon management at airports with measurable results. It covers the operational activities that contribute most to carbon emissions. It is site-specific and can be used at any airport as part of its daily environmental management activity and long term strategy as it helps to guide and support airports through a process of continual improvement and partnership with stakeholders.
