Driving Cleaner Electric Cars and Pickups Beat Gasoline on Lifetime Global Warming Emissions

The Union of Concerned Scientists finds that electric vehicles (EVs) in the United States produce significantly lower lifetime global warming emissions than gasoline vehicles, with the average EV reducing total lifetime emissions by 52% for sedans and 57% for pickup trucks. While EV manufacturing is more carbon-intensive due to battery production, the operational savings quickly offset this 'debt,' with breakeven points occurring between 17,500 and 21,300 miles. The report emphasizes that the emissions benefit of EVs increases as the electricity grid decarbonizes and recommends policies to accelerate renewable energy deployment, improve battery circularity, and increase vehicle efficiency.

• Driving the average electric vehicle (EV) in the United States results in lower global warming emissions than the average new gasoline vehicle everywhere in the country. Based on sales-weighted data, driving the average EV is equivalent to driving a gasoline car that achieves 91 miles per gallon (mpg).
• Over 90 percent of the US population lives in regions where driving the average EV produces fewer emissions than the most efficient gasoline vehicle currently available (rated at 59 mpg). For the most efficient EVs, this benefit extends to 97 percent of the population.
• Electric pickup trucks produce lower emissions than the average new gasoline or diesel pickup truck across the entire United States. On average, EV pickups have emissions equivalent to a gasoline truck getting 59 mpg.
• While EV manufacturing generates more global warming emissions than gasoline vehicle manufacturing—primarily due to battery production—the total lifetime emissions are significantly lower. An average-efficiency EV with a 300-mile-range battery reduces lifetime emissions by 52% compared to an average gasoline sedan (32 mpg), and an electric pickup reduces lifetime emissions by 57% compared to an average gasoline pickup.
• The 'breakeven point'—the distance an EV must be driven to offset its higher initial manufacturing emissions—is reached early in the vehicle's life. For a 300-mile-range electric car compared to an average gasoline sedan, the mean breakeven point is 21,300 miles (approximately 22 months). For a 300-mile-range electric truck compared to an average gasoline pickup, the breakeven point is approximately 17,500 miles (17 months).
• The carbon intensity of the electricity grid used for manufacturing significantly impacts an EV's initial footprint. Using the California regional grid reduces total manufacturing emissions by 10%, while using 100% zero-carbon renewable energy could reduce manufacturing emissions by more than 25%.
• Different battery chemistries have a relatively modest effect on global warming emissions, although they impact other environmental and social factors. For example, Lithium Iron Phosphate (LFP) cathodes produce 85% of the emissions of NMC111 cathodes, while Nickel Cobalt Aluminum (NCA) produces 109%.
• Recycling battery materials can significantly lower the environmental impact of EVs by reducing the need for virgin materials. For NMC chemistries, using recycled materials can reduce total battery manufacturing emissions by approximately 20%.
