Groupe ADP obtains ACA 4 certification
for its Paris airports

Groupe ADP, through its three Paris airports Paris-Charles de Gaulle, Paris-Orly and Paris-Le Bourget, was certified ACA level 4 (Airport Carbon Accreditation - level 4: Transformation) in July. This certification rewards the efforts of Groupe ADP's climate policy, in particular its ambition to reduce its carbon footprint and to be in line with the trajectory of limiting temperature rises to 1.5°C set by the Paris Agreements.

ACA, the global carbon management programme for airports, independently assesses the efforts of airports to manage and reduce their carbon emissions through different levels of certification.

These good results are reflected in a 57% drop in internal greenhouse gas emissions since 2009 at Groupe ADP's Paris airports, thanks in particular to the deployment of renewable energy production (biomass, geothermal energy, etc.), energy efficiency improvement actions, the use of sustainable construction methods and the energy transition of vehicles.

At level 4 of the ACA programme, Groupe ADP has completed the calculation of its external emissions (scope 3) by adding emissions linked to the aircraft's journey from its point of departure to its point of arrival, counted according to the half-cruise method (50% for the airport of departure, 50% for the airport of arrival), and has strengthened the action plan with its stakeholders, and in particular with the airlines, on the subjects of sustainable aviation fuels and hydrogen.

On an international level, several airports of Groupe ADP have also been certified in 2022. Zagreb airport in Croatia and Enfidha airport in Tunisia have obtained level 3 (Optimisation) certification. Izmir, Ankara and Antalya in Turkey, as well as Hyderabadet in India have obtained level 3+ (Neutrality) certification. Finally, New Delhi airport in India and Amman in Jordan obtained level 4+ (Transition) certification.
It should be noted that Santiago airport in Chile has level 1 certification (Mapping) and Liège airport in Belgium has level 2 certification (Reduction).
