Formula 2 and FIA Formula 3 will run on 55% green fuel next season, with the percentage gradually increasing to 100% by the start of the 2027 season.
Meanwhile, F1 will wait until 2026, when new engine regulations come into force, before introducing the fuel.
The move raised concerns that the junior series was being used as a proving ground for F1, with them also testing 18-inch F1 tires before the top tier introduced them.
Michel says it’s a “fantastic thing” and doesn’t believe reliability will be an issue.
He told Motorsport.com: “It’s fantastic. We are not a proving ground, we are pioneers, I prefer to use that word, because what we are going to develop may be a bit different from Formula 1.
“The idea is that we will start next year with a majority of sustainable fuel already, but from 2025 we are going to switch to synthetic fuel until we reach 100% synthetic fuel in 2027, which is something amazing in motor racing, so that the concept of synthetic fuel fuel is you capture CO2 from the atmosphere and turn it into energy.
“So not only are you using something that’s sustainable, but you’re also cleaning the air, that’s what it is. To me, it’s an absolutely fantastic agreement that we have with Aramco because they are going to develop this for us.
“It’s a great thing. Of course, we are part of the overall F1 program that has to be sustainable in 2026 and zero in 2030, and it’s great that we can do that also for ourselves, but also for the overall F1 program “.
When asked if there was a chance that something could go wrong that could cost drivers the championship at such a key stage in their careers, Michel added: “We are doing all the necessary tests to pre-check and check the fuel for his next of use. year and I can tell you for sure that fuel will not be a reliability issue at all.

“Now, in everything, including the engine, we are a single manufacturer category, everyone works with the same material, and at some point you can be unlucky, let’s say.
“At some point, you may also have some technical issues that are not engine-related or fuel-related.
“But as I said, we’re doing everything we need to in terms of testing because, as you can imagine, we go into a very heavy development program before we release the fuel.
“At the moment, we have the engines and the fuel that we’re going to use next year on the dyno for hours and hours and hours before we put it out on the track in the development car, before we’re going to present it to everybody.
“So I really don’t think we’re going to have a reliability issue because of the fuel.”
The agreement is part of Formula 1 and the FIA’s wider sustainability strategy, which sees the series achieve its goal of becoming net zero carbon by 2030.
From 2026, all FIA championships will be required to use 100% green fuel for their cars, which will be introduced to F1 along with next-generation hybrid powertrains.
F1 chief executive Ross Brown said F2 and F3 were a “much easier environment to introduce fuel”, adding that the fact the series only uses one fuel supplier made it easier than F1, where there are “four or five different fuel suppliers with different engines, so it’s a much more complex dynamic.”
He said: “Of course with F1 we started the sustainable fuel initiative.
“We started a partnership with Aramco, and then we realized that with F3 and F2 there is still an opportunity to make an example of what can be done.
“F2 and F3 don’t really have the message power that we have with F1, but it’s still a very useful stepping stone to show what’s possible.”

He also dismissed any concerns about reliability, adding: “To be honest, it’s not a concern. We did 18-inch wheels in F2 before they were in F1.
“We’re going to be relatively conservative: these are very manageable technologies that will be introduced. Taking into account the fuel and the large number of dyno tests, we should not expect any surprises, because they are all the same.
“I think when you introduce a fuel you can never be completely sure how it will affect different engines, so we are holding back in F1 to say to the teams and OMS when we introduce the new engines for 2026, it will be on sustainable fuel.
“So compared to the engines we have today, there is no competitive gain or loss for the driver.
“It would be unfair to introduce sustainable fuel because the characteristics are slightly different and F1 is always at the highest level of technology.
“So you might find that on a sustainable fuel someone has less potential than others, but with the new engines they all start from the same baseline with a lot less worry about that aspect.”
