Toyota and Stellantis part ways with Tesla’s emissions group

04 March 2026

A major change in the EV market is brewing in Europe for 2026. Several large car companies have banded together for years in a group called a "CO2 pool." This group, led by Tesla, helps manufacturers meet strict environmental rules set by the European Union. New reports show that two of the biggest names in the industry - Toyota and Stellantis - are about to leave Tesla's side and stand on their own.

To understand why this matters, we have to look at how Europe manages pollution. The European Union sets targets for how much carbon dioxide (CO2) a carmaker's entire fleet can produce. If a company sells too many gas-powered SUVs and not enough electric cars, they face huge fines. To avoid these penalties, companies that struggle to meet the goals can pay a "clean" company, like Tesla, to join their pool. That way, they average out the emissions, making the whole group look greener on paper. It is a win-win: the big brands avoid fines, and Tesla gets a massive paycheck for being carbon-neutral.

Toyota has been a member of this Tesla-led group for some time, but it seems the Japanese automaker is finally ready to fly solo. Toyota has spent years perfecting hybrid technology. While hybrids still use gasoline, they are much cleaner than traditional engines. Because Toyota sells so many of these hybrids, their average emissions are already very low. Experts believe Toyota is on track to hit its target of 96.3 grams of CO2 per kilometer without any outside help.

Toyota is also getting more serious about pure EVs. The company is currently expanding its lineup with smaller, more affordable models like the new Urban Cruiser. Their existing electric SUV, the bZ4X, has also seen success, even becoming the top-selling electric car in Denmark. With more electric cars joining its fleet, Toyota likely feels it no longer needs to pay Tesla for "pollution credits" that it can now earn for itself.

Stellantis, the giant company that owns brands like Fiat, Peugeot, and Opel, just to name a few, is also making a move. Stellantis was slightly above its emissions targets in recent forecasts, and now it has a secret weapon: Leapmotor. Leapmotor is a Chinese brand that focuses almost entirely on battery-electric vehicles. Stellantis partnered with them and plans to start building the small Leapmotor T03 at a factory in Spain later this year. By producing these cheap electric cars in Europe, Stellantis will lower its overall emissions and avoid high import taxes.

Moving Leapmotor into its own internal pool allows Stellantis to keep its money "in the family" rather than sending it to Tesla. There are also rumors that Stellantis might use Leapmotor's technology to make its own EVs more affordable. This is a smart play, as many drivers are looking for electric cars that don't break the bank. Stellantis is also bringing back some diesel engines in certain markets, so they will need every electric car sale they can get to stay balanced.

This breakup will be a blow to Tesla's bank account. Tesla makes most of its money selling cars, and the cash it gets from these CO2 pools has been a nice bonus for years. If Toyota and Stellantis leave, Tesla loses two of its biggest financial contributors in Europe. This leaves Ford, Honda, Mazda, and Suzuki as the remaining members of the Tesla pool. These companies still rely heavily on gas engines and will likely need Tesla's help for a while longer.

It is important to remember that these decisions aren't permanent just yet. According to European rules, companies have until December 1 of each year to finalize their pooling arrangements. This means Toyota and Stellantis will spend the next several months watching the market very closely. If sales of electric cars slow down or if gas car sales spike, they might get nervous and decide to stay with Tesla for one more year just to be safe.

For now, this is just a sign of a new level of confidence for traditional carmakers. They are no longer watching Tesla lead the way; they are building their own paths toward a cleaner future. Whether through hybrids or new partnerships with Chinese EV brands, the landscape of electric cars in Europe is becoming much more competitive. Tesla might find its "pool" getting a little bit smaller and a lot less profitable as its rivals finally catch up.
