London (AFP) - Formula 1 has launched a plan to become carbon neutral by 2030.
The intention is to wipe out the carbon footprint of activity at race tracks, including road and air transport of staff and equipment to the events.
F1 says it will "move to ultra-efficient logistics and travel and 100% renewably powered offices, facilities and factories" and offset emissions that cannot be cut.
F1 said as a first step it would begin carbon-reduction projects immediately.
It added that it will make all events "sustainable" by 2025, including eliminating single-use plastics and ensuring all waste is reused, recycled or composted.
And in 2021, rules will demand that the petrol used in F1 has a biofuel content of at least 10%.
The high-tech turbo hybrid power-units used to power F1 cars since 2014 are the most efficient car engines in the world in terms of the percentage of fuel energy that is converted into power, a measurement known as thermal efficiency.
F1 engines have a thermal efficiency rating of 50%, whereas a road-car petrol engine is generally in the region of 30%.
