Airports Council International (ACI) has today released the annual results on carbon performance and participation trends for its global carbon management standard for airports, Airport Carbon Accreditation.

The newly released report spans the period from May 2023 through May 2024, with headline results including:

Accredited airports collectively reduced over 1 million tonnes of CO2: -1,037,292 CO2e (-14.8%);

The number of accredited airports rose to 558 across 87 countries — with 70 airports joining the programme for the first time and 132 progressing to a higher level of carbon management;

More than half of the world’s passengers travelled through an Airport Carbon Accredited airport (51.5% -reference year for passenger traffic figure: 2023- of global passenger traffic covered);

At the end of the reporting period, 15 airports had achieved the highest Level 5 accreditation, having reached net zero for emissions under their control (scopes 1 & 2) and committed to full decarbonisation across all scopes by 2050.
