The administration of U.S. President Joe Biden is imposing limits on automobile greenhouse gas emissions that were toughened after environmentalists blasted its earlier proposal as too weak.
The final standards, which govern the release of carbon dioxide from the tailpipes of cars and light trucks, roughly translate into fleet-wide fuel economy values of 55 miles (89 kilometers) per gallon in model year 2026. They replace mandates weakened by former President Donald Trump and will force automakers to pare 22.6% more carbon dioxide emissions from their fleets over the requirements they are replacing.
"We are setting robust and rigorous standards that will aggressively reduce the pollution that is harming people and our planet — and save families money at the same time,” Environmental Protection Agency Administrator Michael Regan said during a ceremony outside the agency’s headquarters Monday.
