Cars and trucks release harmful gases that damage our environment. During his presidency, Donald Trump claimed these emissions weren’t a serious problem. His administration rolled back rules that limited vehicle pollution and blocked states from setting their own standards. Scientists disagree with Trump’s position, pointing to rising carbon dioxide levels from transportation. This policy shift has had real consequences for air quality and public health across America.
While the world continues to rely heavily on cars for transportation, auto emissions have emerged as a critical environmental concern. In 2022, cars and vans released 3.53 billion metric tons of CO2 into our atmosphere, increasing by 1.4% from the previous year. This trend shows no signs of slowing, as light-duty vehicle emissions have jumped 12% globally since 2010.
The alarming rise in global auto emissions continues unabated, with CO2 output climbing yearly despite environmental warnings.
The United States bears significant responsibility in this crisis, consuming nearly 35% of the world’s gasoline in 2023—three times more than China. When drivers burn a single gallon of gasoline, they produce 8,887 grams of CO2. The transportation sector now accounts for 31% of all energy-related CO2 emissions in the U.S.
The Trump administration identified and dismantled several environmental protections, worsening the situation. Vehicle emission standards were rolled back, state-specific air pollution standards were blocked, and electric vehicle accessibility was limited. The Trump administration’s overturned emissions standards increased costs for drivers while significantly worsening air pollution levels. The administration also terminated offshore wind projects while expanding fossil fuel dependency.
The health and economic costs of these decisions are substantial. Transportation emissions contribute to respiratory diseases and premature deaths through fine particulate matter and ozone. Projections suggest expanded fossil-fuel initiatives could cause up to 1,110 deaths annually by 2050, with health costs reaching $15.1 billion per year. The impact is particularly severe for those living near busy roads who face higher risks of developmental delays in children and increased exposure to mental health issues including anxiety and depression.
Electric vehicles offer a cleaner alternative. Though EVs initially produce higher manufacturing emissions (26 metric tons versus 13 metric tons for gas cars), they become environmentally preferable within two years of use. Over their lifetime, EVs emit only 110 grams of CO2 per mile, compared to 410 grams for gas-powered vehicles. Transitioning to these low-carbon transportation options is essential, as renewable energy could achieve over 90% of the emission reductions needed in the electricity sector that powers EVs.
American drivers consumed approximately 137 billion gallons of gasoline in 2023. Each driver’s annual fuel purchases result in 5.22 tons of CO2 emissions, with “superusers” producing at least 11 tons yearly. Every gallon burned creates 20 pounds of CO2 that remains in the atmosphere, affecting our climate for generations to come.
