Paris-Orly achieves top carbon accreditation

Paris-Orly airport has received the highest level of certification under the Airport Carbon Accreditation (ACA) program, known as ACA 5. This certification recognizes the airport’s significant progress in reducing its carbon footprint and aligning with global climate goals.

Emissions reduction progress

The ADP group, which manages the airport, reported that emissions from the airport’s own operations have dropped by 92% since 2010. The airport aims to achieve net zero emissions for all its activities, including those from its supply chain, by 2050.

Carbon neutrality ahead of schedule

Paris-Orly has reached carbon neutrality for its scope 1 and scope 2 emissions—those directly produced by the airport and its energy use—five years earlier than planned. This achievement is part of a broader effort to cut energy consumption and switch to cleaner energy sources.

Energy efficiency improvements

In 2025, the airport reduced its electricity use by about 16% compared to 2019, and heat consumption dropped by around 35%. These reductions were achieved through modernized equipment, optimized heating and cooling systems, and improved lighting and ventilation.

Renewable energy sources

Paris-Orly now gets 87% of its heat from renewable sources, including geothermal energy, heat pumps, and waste heat recovery. The airport also uses biomethane to replace part of its natural gas consumption, further lowering its carbon impact.

Decarbonizing transportation and construction

The airport is working to reduce emissions from its vehicle fleets by switching to electric vehicles and using low-carbon fuels for non-electrifiable equipment, such as snow removal machines. Major construction projects, like the renovation of runway 4, aim to recycle nearly 90% of demolition materials.

Expanding renewable energy and sustainable fuels

Paris-Orly plans to increase its production and use of solar energy. To address scope 3 emissions, the airport is encouraging airlines to use more sustainable aviation fuels and is improving public transport access for passengers and employees to reduce the environmental impact of ground operations.
