The Trump administration plans to release new fuel economy standards on Monday (September 28), easing regulations on automakers' control of pollution from gasoline-powered vehicles and light trucks. Trump stated on his social media account last Saturday that relaxing mileage requirements would "reduce waste in American auto manufacturing" and save families "thousands of dollars."

The new standard significantly relaxes the mileage requirement, lowering the 2031 target from 50.4 to 34.5 miles per gallon.

Fuel economy standards dictate the mileage a new car needs to achieve per gallon of gasoline. According to projections from last December, the new standards will bring the industry average fuel consumption for 2031 model year light vehicles to approximately 34.5 miles per gallon, significantly lower than the 50.4 miles per gallon projected under the Biden administration's rules. Trump stated that relaxing mileage requirements will reduce waste in car manufacturing, save families thousands of dollars to buy new cars, and boost American auto production. Since taking office, Trump has relaxed vehicle emissions regulations, eliminated penalties for automakers that do not meet federal mileage standards, and ended consumer subsidies for electric vehicle purchases of up to $7,500.

As the new regulations were introduced, the average price of a new car in the United States surpassed $50,000, and gasoline prices climbed.

The new regulations come against the backdrop of rising new car prices and gasoline costs in the United States. According to Kelley Blue Book data, the average price of a new car in the U.S. in August was $50,089, breaking the $50,000 mark for the first time since December of last year. Meanwhile, gasoline costs for Americans are also increasing as the conflict between Washington and Iran disrupts global fuel supplies. Data from the American Automobile Association shows that the average price of gasoline nationwide was $4.47 per gallon last Sunday, up from $4.09 a month earlier. The government and automakers say the new regulations will make it easier for Americans to access the variety of gasoline-powered vehicles they need and can afford.

Environmentalists strongly condemned the policy move, saying it would make driving more expensive.

The revised standards were immediately condemned by environmentalists upon their release. The director of the Safe Climate Transportation Campaign at the Center for Biodiversity stated that the final rules "ignore the feasibility of clean technologies and the millions of fuel-efficient vehicles already on the road," adding that "Trump's arbitrary disregard for reasonable fuel efficiency standards at a time when consumers are already suffering from high fuel prices is undoubtedly the worst possible time for them." The head of the Sierra Club's "Clean Transportation for All" campaign vowed to oppose the regulation, stating that relaxing fuel standards would also "make driving more expensive," adding that "inefficient cars mean consuming more gasoline, spending more on gas, and causing more air pollution in our communities."

Environmental impact and emissions: By 2035, significant amounts of additional carbon dioxide and pollutants will be emitted annually.

The National Highway Traffic Safety Administration (NHTSA) estimates that the new regulations, which take effect in 2024, will reduce gasoline consumption by 14 billion gallons by 2050. The agency also stated that while the upfront costs of new, more fuel-efficient vehicles are higher, the fuel savings over the lifespan of a car or truck will far outweigh these costs. Without these standards, by 2035, vehicles could produce 22,111 tons more carbon dioxide emissions annually than under the Biden-era regulations. This also translates to an additional 90 tons of deadly particulate matter and 4,870 tons of soot components, such as nitrogen oxides and volatile organic compounds, annually in the coming years. Since the energy crisis of the 1970s, automakers have been implementing mileage standards, or corporate average fuel economy, and gradually improving the average fuel efficiency of their vehicles over time.

Editor's Summary

The revised fuel economy standards directly lower the industry average fuel consumption target for 2031 from 50.4 mpg to 34.5 mpg, aiming to reduce compliance costs for automakers and lower new car prices. Against the backdrop of average new car prices exceeding $50,000 and gasoline prices rising due to geopolitical conflicts, the policy attempts to alleviate consumer burden and boost domestic production by relaxing regulations. However, environmental groups criticize it for ignoring the feasibility of clean technologies and warn that it will lead to higher fuel consumption, more emissions, and air pollution. Estimates from the National Highway Traffic Safety Administration show that relaxing standards could significantly increase carbon dioxide and pollutant emissions for many years to come. The policy's effectiveness ultimately depends on the actual enforcement, market choice between gasoline and electric vehicles, and the impact of energy price trends on consumer purchasing decisions.

Frequently Asked Questions

Q: What are the core changes in the new fuel economy standards? A: The new standards significantly lower the 2031 average fuel economy target for the light vehicle industry from approximately 50.4 mpg (50.4 mpg) during the Biden administration to 34.5 mpg (50.5 mpg), substantially relaxing mileage requirements for gasoline-powered vehicles and light trucks. Q: Why did the Trump administration introduce these standards at this time? A: The government believes that strict standards increase manufacturing waste and costs, while relaxation can save families thousands of dollars in car purchase costs and promote American auto production. Previously, related fines and electric vehicle subsidies had been eliminated, forming a complementary policy. Q: What was the state of the US auto and gasoline markets when the new regulations were introduced? A: The average price of a new car in August reached $50,089, exceeding $50,000 for the first time this year; the average gasoline price was approximately $4.48 per gallon, significantly higher than a month earlier due to the US-Iran conflict, increasing cost pressure on consumers. Q: What are the main reasons for environmentalists' opposition? A: They believe the rules ignore existing clean technologies and energy-efficient vehicles, undermine efficiency standards during periods of high fuel prices, and will lead to higher gasoline consumption, higher driving costs, and more severe air pollution. Q: What specific impact will relaxing the standards have on emissions? A: Estimates show that by 2035, automobiles may emit an additional 22,111 tons of carbon dioxide annually, along with an additional 90 tons of particulate matter and 4,870 tons of smoke components, leading to a long-term increase in fuel consumption and pollutant release.
