Toyota and Stellantis exit Tesla emissions pool under EU rules
Toyota and Stellantis have withdrawn from Tesla’s European carbon emissions pooling arrangement for 2026, according to newly filed documents with the European Union, removing two of the largest contributors to a coalition that analysts once estimated could generate more than €1 billion annually for the electric vehicle manufacturer.
The move reflects the continuing decline of Tesla’s regulatory credit business, a once highly profitable revenue stream that has weakened globally since the United States eliminated its emissions credit market last year. Tesla reported that regulatory credit revenue fell 28 percent in 2025 compared with the record $2.76 billion posted in 2024.
Under European Union regulations, automakers that cannot meet fleetwide carbon dioxide limits on their own can form “pools” with manufacturers that produce more zero emission vehicles. By joining these pools, companies can lower their average emissions in exchange for payments to the credit holder.
For the 2025 compliance year, Tesla’s pool included Toyota, Stellantis, Ford, Honda, Mazda, Subaru, Suzuki and Chinese electric vehicle maker Leapmotor. However, documents submitted to EU regulators for 2026 show the pool shrinking to only Tesla, Ford, Honda, Mazda and Suzuki, with Toyota, Stellantis and Leapmotor no longer listed.
Toyota believes it can now meet European emissions targets independently. The Japanese manufacturer has maintained a large share of hybrid vehicles in its European lineup and continues expanding its fully electric offerings. Models such as the Urban Cruiser and the bZ4X have supported this strategy, with the bZ4X becoming the best selling electric vehicle in Denmark in February 2026.
Stellantis has chosen a different strategy by forming a separate emissions pool with Leapmotor. The partnership allows Stellantis to offset its fleet emissions using the Chinese manufacturer’s zero emission vehicle sales without purchasing credits from Tesla.
Leapmotor delivered more than 17,000 vehicles in Europe during the fourth quarter of 2025 and expanded its presence to more than 800 retail locations across the region. The collaboration with Stellantis also extends beyond compliance arrangements, as the European automaker is evaluating the adoption of Leapmotor’s electric vehicle technology for several of its brands, including Fiat, Opel and Peugeot.
The departures increase pressure on a revenue stream that once flowed almost directly into Tesla’s net profit with minimal cost. In the United States, the removal of penalties tied to Corporate Average Fuel Economy standards eliminated a major incentive for traditional automakers to buy Tesla’s regulatory credits.
Analysts at William Blair forecast that Tesla’s U.S. credit revenue could fall to about $595 million in 2026 and potentially disappear entirely by 2027.
In Europe, regulatory changes have also eased pressure on automakers. The European Commission now allows companies to average their emissions compliance over a three year period from 2025 to 2027, reducing the urgency to purchase credits from Tesla.
However, emissions pooling decisions within the EU do not need to be finalized until December 1 each year. This means Toyota or Stellantis could theoretically rejoin Tesla’s pool if their emissions performance worsens during the compliance period. Still, analysts say the trend suggests more automakers are finding ways to meet European climate rules without relying on Tesla’s regulatory credit system.
