Formula 1 has developed a synthetic sustainable fuel to be introduced in 2026 as part of its programme to be net-zero carbon by 2030.
Synthetic fuels are manufactured by an industrial process and emit in their burning only the carbon that was taken out of the atmosphere to make them.
The fuel can be used in standard internal combustion engines and could help the car industry to decarbonise.
In F1, it will be used in new-generation hybrid engines from 2026.
These will increase the proportion of power produced by the hybrid part of the engine compared to the already super-efficient motors used since 2014.
F1 re-emphasised its commitment to fully sustainable fuels in a statement on Monday detailing its progress towards its net-zero goals.
The statement did not specify that the fuel it was developing was synthetic - as opposed to derived from bio-mass - but a source within F1 confirmed to BBC Sport that was the case.
