Formula 1 says it is on track to achieve its commitment to become net-zero carbon by 2030.

Its annual review of the 2025 season found a 35% reduction in the sport’s carbon footprint from the 2018 baseline and a 12% reduction since 2024.

Total carbon dioxide emissions have come down from 228,793 tonnes in 2018 to 148,805 in 2025.

Emissions from F1’s own operations as well as the factories, operations and travel of all the teams are included in the figures.

Among the driving factors behind the numbers are shifting from air to sea freight, investment in sustainable aviation fuel and revisions to the schedule.

Emissions from factories and facilities have dropped by 64% compared to 2018 and 14% year on year, a statement said.

Logistics emissions are down 21% year on year, and 29% since 2018.

An example of the moves F1 is making to cut emissions is grouping the race calendar geographically, so freight and, in many cases, personnel can move from one event to another more efficiently.

Although not included in the figures for the 2025 report, a spokesperson said the decision to run the Miami and Canadian Grands Prix consecutively this year, rather than having a European race or two between them, had cut logistics and travel carbon emissions by almost 3%.

This is one example of a number of similar reshuffles of the calendar, such as since 2024 moving the Japanese Grand Prix to the spring, so it can be grouped with the Australian and Chinese races, from its previous date in the autumn.

In 2026 F1 switched to mandating advanced sustainable fuels in races, although emissions caused by the competition itself are a very small percentage of the total.

These fuels produce an 80% reduction in greenhouse gas emissions compared to a fossil-fuel comparator.

F1 says its emissions data calculations are completed through a third-party reporting platform.

A statement said: “The platform improves the accuracy and transparency of calculations with visibility over data input, categorisation, and calculation methodology.”

F1 president and chief executive officer Stefano Domenicali said the results had been “made possible by the collective effort across the sport to reduce our environmental impact”.

“From calendar rationalisation to greater investment in sustainable fuels and alternative energy solutions, we have reduced our footprint while the sport continues to grow and reach new audiences around the world,” he said.

Ellen Jones, F1’s head of environmental, social and governance, said: “By doubling the sport’s investment in sustainable aviation fuel, making our first investment in sustainable maritime fuel, and continuing to work closely with promoters, teams and partners, we are driving further emissions reductions while accelerating the adoption of the latest technologies.

“Together, these initiatives show that sustainable operations are not only possible at a global scale, but can be delivered without compromising the performance, ambition or spectacle that define Formula 1.”

F1’s ‘Net Zero by 2030’ carbon commitment sets a minimum target of a 50% reduction in absolute emissions compared to 2018, with any remaining unavoidable emissions offset using “credible programmes aligned with best practice guidance”.
