Tesla had lowest tailpipe CO2 emissions & highest fuel economy in 2021 EPA Auto Trends report finds

Published

on

Tesla had the lowest tailpipe CO2 emissions for 2021, a new report published by the U.S. Environmental Protection Agency (EPA) stated. The EPA released its annual Automotive Trends report, and findings reveal that Tesla is leading the way with the lowest tailpipe CO2 emissions and the highest fuel economy of all large manufacturers.

Naturally, Tesla is the leader since it doesn’t produce any vehicles with an internal combustion engine (ICE), and as a result, there are no tailpipes. However, other manufacturers such as Kia and Toyota are showing improvements now that they have begun producing electric vehicles.

Following Tesla, Subaru, Kida, Hyundai, Nissan, and Honda had reductions in CO2 tailpipe emissions. Stellantis had the highest new vehicle average CO2 emissions and lowest fuel economy of the large manufacturers, the report noted.

Tesla was followed by a close grouping of Subaru, Kia, Hyundai, Nissan, and Honda. Also, for the model year of 2021, Stellantis had the highest new vehicle average CO2 emissions and lowest fuel economy of the large manufacturers. General Motors and Ford followed Stellantis.

The table below shows manufacturers and vehicles with the highest fuel economy by year. The manufacturer with the highest fuel economy for both 2021 and 2022 (preliminary) was Tesla. Stellantis was the lowest and has been the lowest since 2012. The Tesla Model 3 was the overall vehicle with the highest fuel economy and is expected to be replaced by the Lucid Air in 2022.

The report also noted that in 2021, hybrid vehicles reached a new high of 9% of all production.

“This increase was mostly due to the growth of hybrids in the truck SUV and pickup vehicle types. The combined category of electric vehicles (EVs), plug-in hybrid vehicles (PHEVs), and fuel cell vehicles (FCVs) increased to 4% of production in model year 2021 and are projected to reach 8% of production in model year 2022, due to expected growth in EV production across the industry,” it stated.

Other key findings from the report found that in 2021, the average estimated real-world CO2 emission rate for all new vehicles fell by 2 g/mi to 347 g/mi, which was the lowest ever measured.

“Real-world fuel economy remained at a record high 25.4 mpg.”

All vehicle types are at record-low CO2 emissions, and preliminary data shows that the emissions and fuel economy for 2022 are expected to improve from 2021 levels.

Brazil’s Supreme Federal Court has ordered the closure of an investigation involving Elon Musk and social media platform X. The inquiry had been pending for about two years and examined whether the platform was used to coordinate attacks against members of the judiciary.

The decision was issued by Supreme Court Justice Alexandre de Moraes following a recommendation from Brazil’s Prosecutor-General Paulo Gonet.

According to a report from Agencia Brasil, the investigation conducted by the Federal Police did not find evidence that X deliberately attempted to attack the judiciary or circumvent court orders.

Prosecutor-General Paulo Gonet concluded that the irregularities identified during the probe did not indicate fraudulent intent.

Justice Moraes accepted the prosecutor’s recommendation and ruled that the investigation should be closed. Under the ruling, the case will remain closed unless new evidence emerges.

The inquiry stemmed from concerns that content on X may have enabled online attacks against Supreme Court justices or violated rulings requiring the suspension of certain accounts under investigation.

Justice Moraes had previously taken several enforcement actions related to the platform during the broader dispute involving social media regulation in Brazil.

These included ordering a nationwide block of the platform, freezing Starlink accounts, and imposing fines on X totaling about $5.2 million. Authorities also froze financial assets linked to X and SpaceX through Starlink to collect unpaid penalties and seized roughly $3.3 million from the companies’ accounts.

Moraes also imposed daily fines of up to R$5 million, about $920,000, for alleged evasion of the X ban and established penalties of R$50,000 per day for VPN users who attempted to bypass the restriction.

Brazil remains an important market for X, with roughly 17 million users, making it one of the platform’s larger user bases globally.

The country is also a major market for Starlink, SpaceX’s satellite internet service, which has surpassed one million subscribers in Brazil.

FCC chair criticizes Amazon over opposition to SpaceX satellite plan

U.S. Federal Communications Commission (FCC) Chairman Brendan Carr criticized Amazon after the company opposed SpaceX’s proposal to launch a large satellite constellation that could function as an orbital data center network.

Carr made the remarks in a post on social media platform X.

Amazon recently urged the FCC to reject SpaceX’s application to deploy a constellation of up to 1 million low Earth orbit satellites that could serve as artificial intelligence data centers in space.

The company described the proposal as a “lofty ambition rather than a real plan,” arguing that SpaceX had not provided sufficient details about how the system would operate.

Carr responded by pointing to Amazon’s own satellite deployment progress.

“Amazon should focus on the fact that it will fall roughly 1,000 satellites short of meeting its upcoming deployment milestone, rather than spending their time and resources filing petitions against companies that are putting thousands of satellites in orbit,” Carr wrote on X.

Amazon has declined to comment on the statement.

Amazon has been working to deploy its Project Kuiper satellite network, which is intended to compete with SpaceX’s Starlink service. The company has invested more than $10 billion in the program and has launched more than 200 satellites since April of last year.

Amazon has also asked the FCC for a 24-month extension, until July 2028, to meet a requirement to deploy roughly 1,600 satellites by July 2026, as noted in a CNBC report.

SpaceX’s Starlink network currently has nearly 10,000 satellites in orbit and serves roughly 10 million customers. The FCC has also authorized SpaceX to deploy 7,500 additional satellites as the company continues expanding its global satellite internet network.

Tesla Energy has received a license to supply electricity in the United Kingdom, opening the door for the company to serve homes and businesses in the country.

The license was granted to Tesla Energy Ventures Ltd. by UK energy regulator Ofgem after a seven-month review process.

According to Ofgem, the license took effect at 6 p.m. local time on Wednesday and applies to Great Britain.

The approval allows Tesla’s energy business to sell electricity directly to customers in the region, as noted in a Bloomberg News report.

Tesla has already expanded similar services in the United States. In Texas, the company offers electricity plans that allow Tesla owners to charge their vehicles at a lower cost while also feeding excess electricity back into the grid.

Tesla already has a sizable presence in the UK market. According to price comparison website U-switch, there are more than 250,000 Tesla electric vehicles in the country and thousands of Tesla home energy storage systems.

Ofgem also noted that Tesla Motors Ltd., a separate entity incorporated in England and Wales, received an electricity generation license in June 2020.

The new UK license arrives as Tesla continues expanding its global energy business.

Last year, Tesla Energy retained the top position in the global battery energy storage system (BESS) integrator market for the second consecutive year. According to Wood Mackenzie’s latest rankings, Tesla held about 15% of global market share in 2024.

The company also maintained a dominant position in North America, where it captured roughly 39% market share in the region.

At the same time, competition in the energy storage sector is increasing. Chinese companies such as Sungrow have been expanding their presence globally, particularly in Europe.
