Actions for the climate: over 250 airports already active

49 operated by carbon neutral companies

Following last month’s COP24 UNFCCC Climate Change Conference in Katowice, Poland, Airports Council International today provided an update on the latest developments among the community of 259 airports currently in the global carbon management standard, Airport Carbon Accreditation (ACA).

The latest airport operator to become carbon neutral is Aeroporto di Napoli in Italy. After gradually making its way through the different levels of ACA, demonstrating the CO2 reduction it has made on-site and the engagement of aviation partners, it has invested in Gold Standard offsets to address its remaining residual emissions.

With 4 different levels of accreditation covering all stages of carbon management (Mapping, Reduction, Optimisation and Neutrality), Airport Carbon Accreditation is independently administered, institutionally-endorsed and has the support of the United Nations Framework Convention on Climate Change (UNFCCC), United Nations Environment Programme (UNEP), the International Civil Aviation Organisation (ICAO), US Federal Aviation Administration and the European Commission (EC).

Moving on up

The following airports recently moved up to Level 3 ‘Optimisation’, by stepping up their activities from reducing their own carbon emissions, to also engaging other companies on the airport site to reduce their emissions: Narita International Airport, Kansai & Osaka Airports (Japan), Taoyuan International Airport (Taiwan), Quito Mariscal Sucre Airport (Ecuador), Bucharest Henri Coanda Airport (Romania), Larnaca & Paphos Airports (Cyprus) and Lapland Airports (Enontekio, Ivalo, Kemi Tornio, Kittila, Kuusamo and Rovaneimi in Finland).

Airports recently successfully moved up to Level 2 ‘Reduction’ include Noumea la Tontouta (New Caledonia), Salahah Airport (Oman) as well as Dinard Bretagne and Rennes Bretagne (France) as these airports progressed from moving mapping their carbon emissions, to actively reducing them.


Around the world, several airports have become Airport Carbon Accredited for the first time. Kobe Airport in Japan at Level 2 ‘Reduction’; Zhengzhou Xinzheng International Airport in China at Level 1 ‘Mapping’ and the 4 airports of the Airports Authority of India also at Level 1 ‘Mapping’ (Netaji Subhash Chandra Bose Airport; Bhubaneswar Biji Patnail Airport; Varanasi Lal Bhadaur Shastri Airport and Trivandrum International Airport). In Europe, La Réunion Roland Garros Airport joined at Level 2 Reduction and Cornwall Airport Newquay in the UK rejoined the programme at Level 1 Mapping.

In the Americas Kelowna International Airport, Pisco Airport and Salvador Bahia International all became accredited for the first time at Level 1 Mapping.

To reduce their carbon emissions, airport operators need to consider the full extent of the emissions sources under their direct control. Investment in more energy efficient lighting, heating, switching to hybrid or electric ground vehicles, onsite renewables, energy management tools and employee behavioural change all have a part to play. The possibilities become even more diverse when airport operators engage other stakeholders on the airport site as well (Level 3 of the programme), with initiatives such as Airport-Collaborative Decision-Making (A-CDM), Continuous Descent Operations and Time-Based Separation lowering airline-associated carbon emissions and better intermodal access and electric or hybrid taxis offering passengers cleaner transport solutions to/from the airport.

Carbon neutral airports at Level 3+ of the programme have to provide evidence of undertaking all the actions required by the programme (mapping their emissions, reducing them and engaging others on the airport site), before investing in responsible carbon offsets. The 44 carbon neutral airports during Year 9 of the programme (May 2017 to May 2018) offset 672,000 tonnes of CO2 in residual emissions.
