Formula 2 and Formula 3 will use Advanced Sustainable Fuels in competitive action for the first time as the 2023 seasons begin, ahead of F1's switch to this in 2026.
As approved by the World Motor Sport Council, both F2 and F3 are set to run 55 per cent Advanced Sustainable Fuels through the duration of the championships in the year ahead.
Each will gradually increase the sustainable elements year-on-year until 100 per cent is reached for the 2027 campaigns, which will follow on from Formula 1 switching to Advanced Sustainable Fuels in 2026 alongside the new engine regulations.
Over 8000 laps on the 55 per cent Advanced Sustainable Fuel were completed by F2 and F3 drivers during pre-season testing, ahead of both categories kicking off their campaigns in Bahrain over the weekend of 3-5 March.

Net Zero Carbon by 2030
The move marks part of Formula 1's sustainability strategy, with the intention to become Net Zero Carbon by 2030. A plan to work with F2 and F3 to trial sustainable fuels was previously highlighted as part of the mission.
Stefano Domenicali, CEO of F1, commented: "A lot of research and dedication has gone into the creation of the Advanced Sustainable Fuels that the F2 and F3 cars will be using this year, and we’re delighted to see it now in action on the racetrack.
"The role of the F2 and F3 Championships has never been more important, as they continue to nurture the next generation of driver talent and inspire game-changing innovation.
"Sustainability is a huge focus for us at F1 as the business continues on the journey to being Net Zero Carbon by 2030, and the development of the Advanced Sustainable Fuels alongside our Global Partner Aramco, is a huge step that will see the sport and the wider automotive industry move towards a more sustainable future."
Bruno Michel, CEO of Formula 2 and Formula 3, also hailed the move as "an extraordinary breakthrough in motorsport" and added that it was a "major step in making our sport more sustainable".
