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."
