In 2019, the race generated over 36,000 tonnes of CO₂. The ACO identified areas of improvement and has set about achieving carbon neutrality by 2030, with the aim of reducing emissions by 30%. The carbon neutral project is known as Race to 2030.

For 2022 FIA World Endurance Championship, including the 24 Hours of Le Mans switched to 100% renewable biofuel, the Excellium Racing 100 from exclusive supplier, TotalEnergies, which significantly reduced the impact of the race. Tyres and fuel now account for 1.4% of total emissions, down from 2.5%.

The 24 Hours of Le Mans has also signed a charter comprising 15 commitments, drawn up by the French ministry of sport and WWF France.

Mohammed Ben Sulayem, FIA President, said: “I congratulate the Automobile Club de l’Ouest for obtaining the FIA Two-Star Environmental Accreditation and switching to 100% renewable biofuel as part of the FIA World Endurance Championship. Motor sport is mobilised to reduce its environmental impact. The FIA is committing to leading the way towards a sustainable sport for the future.”

Pierre Fillon, ACO President, said: "The 24 Hours of Le Mans has always been a pioneer in the field of innovation. This innovation is now being used to reduce our carbon footprint and we are very pleased that the FIA has granted us this two-star accreditation. This is a step towards the three-star accreditation we are aiming for next year. CSR is at the heart of our strategy, including aiming for carbon neutrality by 2030."
