Tesla generated nearly 34-million metric tons of greenhouse gas credits in the 2023 model year by selling electric vehicles while the car industry racked up significant credit deficits in the face of more stringent emissions standards.
In a report first seen by Reuters, the Environmental Protection Agency (EPA) said on Monday new vehicle fuel economy increased by 1.1 miles (1.8km) per gallon in 2023, reaching a record high 10,42l/100km. The EPA said fleetwide fuel economy is preliminarily projected to rise to 8.4l/100km in the 2024 model year.
The industry as a whole generated nearly 11-million metric tons, or megagrams, of greenhouse gas emission credit deficits, led by General Motors, which posted a 17.8-million metric ton deficit.
GM purchased about 44-million credits in 2023, the EPA report said, while Tesla sold about 34-million, the largest of all transactions.
Excluding Tesla, carmakers generated a deficit of 43.5-million credits in 2023. By contrast in 2022, the industry earned a total of 3-million credits, led by Tesla’s 19.1-million credits.
The EPA said the industry has a total surplus of 123-million metric tons of credits to meet future requirements.
GM also had to forfeit another 49-million metric tons of credits as part of a settlement in July of an EPA investigation that found excess emissions from approximately 5.9-million GM vehicles.
Reuters reported last week that US president-elect Donald Trump’s incoming administration plans to target federal regulations that aim to make automobiles more fuel-efficient and incentivise a shift toward electric vehicles, citing sources.
In March, the EPA finalised new rules requiring carmakers to cut emissions by 49% by 2032 over 2026 levels compared with 56% under the proposal last year after dramatically tightening 2024 through to 2026 requirements.
Stellantis had the lowest fuel economy of major carmakers, followed by GM and Ford, while Tesla is the most efficient, followed by Kia and Hyundai.
Last year, Reuters reported Stellantis and GM had paid a total of $363m (R6.57bn) in civil penalties for failing to meet US fuel economy requirements.
Horsepower, vehicle weight and size all hit new records in 2023. Sedans and wagons sold fell to 25% of vehicles sold in 2023, while SUVs rose to 58%.
The EPA said electric and plug-in electric production rose from 6.7% in 2022 to 11.5% in 2023 and projected it to reach 14.8% in 2024.
