Electric Vehicles Cut Emissions 59% Across All Models

Scientists just analyzed the carbon footprint of every single car, truck, and van sold in America last year, and the results offer real hope for our climate future.

Researchers examined all 2023 model year vehicles available in the United States, comparing emissions across their entire lifetime from factory to junkyard. They looked at traditional gas engines, hybrids, plug-in hybrids, and fully electric models across every vehicle type.

The verdict is clear. Electric vehicles reduce greenhouse gases compared to gas-powered cars in every scenario tested, including regions with dirty electricity grids, extreme cold climates, and shorter battery lifespans.

The study went further, imagining what would happen if every vehicle sold in 2023 had been electric instead. The result would be a 59% reduction in lifetime emissions, preventing 820 million tons of carbon dioxide from entering the atmosphere.

Here's the surprising part. Three-quarters of that reduction would come from electrifying pickup trucks and SUVs, not sedans.

The Ripple Effect

Light trucks now make up 62% of vehicles sold in America, yet only 3% of large SUVs and pickups are fully electric compared to 36% of small SUVs. This gap represents our biggest opportunity.

When an electric pickup replaces a gas-powered one, the emissions savings are larger than swapping out a sedan. These heavy-duty vehicles guzzle more fuel and rack up bigger carbon footprints over their lifetimes.

The findings matter because they address real-world concerns. Even accounting for emissions from electricity generation and battery production, electric vehicles come out ahead. Cold weather and coal-heavy power grids reduce the benefits but don't eliminate them.

As America's electricity grid gets cleaner with more solar and wind power, the advantage of electric vehicles will only grow. The transportation sector accounts for nearly 30% of U.S. greenhouse gas emissions, with passenger vehicles contributing the majority.

The path forward is becoming clearer. Electrifying the trucks and SUVs Americans actually buy, not just the sedans highlighted in earlier studies, unlocks the greatest potential for cutting transportation emissions and building a cleaner future.
