Brothers, if you've never heard a twin-turbo, V12 at 220 miles per hour you missed the golden age. Very little ground effect, just brute fucking force. Bring back the old engines!
The cars might be fast, but they're also only 0.7% of F1's carbon footprint.

Forget the race cars; here’s how F1 will really cut carbon emissions
The cars might be fast, but they're also only 0.7% of F1's carbon footprint.

Formula 1 might be a sport, but it's also a $2.6 billion business with shareholders, and like pretty much every other multibillion-dollar business with shareholders, that means it's under increasing scrutiny regarding the amount of carbon emissions it's responsible for. Currently, that's about 250,000 tons a year, but the sport says it wants to reduce that to net zero by 2030. I spoke with F1's chief of sustainability to learn more about how it's doing that, and you may be surprised to learn that race cars have very little to do with it.
While F1's carbon footprint is just a fraction of other global sporting events like the Olympics or World Cup, it's a more visible target, considering it involves cars driving around a track burning gasoline. But focusing only on the cars is a mistake.
Forget the cars
For one thing, since the introduction of hybrid powertrains in 2014, F1 cars have become extremely efficient.
There are a pair of hybrid systems—one that captures energy under braking and another that captures energy from exhaust gases—and the 1.6 L V6s burn their gasoline more efficiently than any other internal combustion engine ever made,
approaching or perhaps even passing 50 percent now.
Looking further ahead to 2026,
the sport will also switch to carbon-neutral synthetic fuels that are made by capturing CO2 from the air and combining it with hydrogen produced by the electrolysis of water.
That won't make F1's fuel bill any cheaper, but it should mean none of the CO2 that comes out of an F1 car tailpipe went into the fuel tank in the form of fossil fuels. (If one were to be very tendentious, they could say that at some point the carbon in the synthetic fuel was part of a hydrocarbon molecule that got burned in an engine and released into the atmosphere, but those people don't get invited back to parties.)
But actually, the reason not to focus on the F1 cars is because they're a rounding error in terms of the sport's annual footprint. Ten teams running two cars on track for a maximum of six hours a weekend, 23 times a year, just doesn't add up to that much. Factor in running cars at test sessions or on the dyno, and it still only accounts for 0.7 percent of F1's scope 1 and scope 2 emissions.
"When you look at that net-zero goal and the work that it takes to deliver it, sustainable fuels is 1 percent of that from a carbon footprint perspective, and while it's fantastic for future innovation, and road relevance, I really need to focus on what are the actions that we take today with the technologies today," said Ellen Jones, head of sustainability at F1.
F1 is much like any other sport
So if it's not the race cars, where does that quarter of a million tons of carbon come from? "When you look at what's driving our carbon footprint, like many people, it is our operations, and it's travel and logistics. And so when we look at carbon footprint, it's the energy you use, it's the energy in your operations," Jones told me.
A quick and easy change was ensuring F1's offices are powered by renewable energy. "The infrastructure in the UK is available, so we can make that procurement decision," Jones said.
Travel and logistics account for two-thirds of F1's carbon footprint. One thing the sport has done is to send fewer people to each race by doing more of the broadcasts remotely. (If you subscribe to F1's streaming service, you'll note that much of the commentary team is coming to you from Biggin Hill outside of London, not wherever that weekend's race is being held.)
And all the broadcast gear—
and the tech center—now travel in new containers that fit on more efficient airplanes.
"When you look at logistics, you have three key levers: you have the amount that you ship, you have the mode that it travels on, and you have the distance that it travels. And every single piece of equipment to help broadcast an F1 race has to go through that consideration of, 'Does this need to travel? Can we do this at home? How can we travel in the most efficient way? Can this travel in a different way—can we use a regional hub?' so that will be an ongoing piece of work," she told Ars.
Renewables at race tracks
Another puzzle piece is the energy needed to run each race weekend. "There's a surge of energy that requires, not just the cars going around, but also the grid energy, the generator power, and how we influence what's the correct technology for the operational context where we are racing," Jones explained.
"So sometimes that will be on-site generation like in Bahrain. Sometimes that will be using biofuels like in Zandvoort [in the Netherlands]. And other times, it will be a mixture of technologies because it's all about the operational context and how you deliver what needs to be done for that event today," she continued. Indeed, the Bahrain International Circuit added a solar plant that generated more than 5 MW of energy and is in the process of building a 14 MWh extension that will make the facility entirely carbon neutral all year.
"From a technology side, Formula One has a history that people understand when you talk about innovation. You talk about speed, you talk about safety, those are connections that people understand as part of Formula One, and we really need to show that the next generation of technology has to work with sustainability, too, and that needs to be part of that definition," Jones said.

Grands prix aren't under F1's complete control—each race has a local promoter that pays the sport a sanctioning fee (often a very large one) to come and race. Now, their contracts require them to align with F1's 2030 net-zero goal, and the sport works with promoters to make each event more sustainable. (However, those promoters are probably an impediment from grouping races together geographically—spacing them out on the calendar means that the Miami race does not cannibalize ticket sales from Austin, to give one example.)
"We put out guidance for them about how we want them to deliver across six key areas, because it's not just energy—it's also plastic and waste, it's local fan travel, it's well-being and nature. And now what we do is we track on an annual basis how they're delivering against those goals," she explained.
Jones says that last year, half of the F1 race promoters were already using renewable energy on-site, and in addition to the solar energy at Bahrain and biofuels at the Dutch Grand Prix, in Australia this year, the organizers trialed hydrogen fuel cell generators (something NASA demoed
in 2011 at the final Space Shuttle launch). And this year's Saudi Arabian Grand Prix saw the organizers working on waste management.
Still, Jones has a daunting task ahead of her. "When you talk about impact, Formula One just keeps getting bigger and bigger. And that's been the biggest lesson for me—you think you have it sorted in one area, and then you're like, actually, that's much more, and so how we ensure every stakeholder understands what their responsibility is in delivering our sustainability strategy, whether it's from a fan perspective, all the way through to our own internal operations—it is a huge culture change shift," she said.
