Fuel Efficiency Standards

President Trump is significantly reducing federal fuel efficiency and emissions standards for vehicles to below those set by the Obama administration. The Obama regulations required automakers to build vehicle fleets that would average about 54 mpg by 2025. The Trump rule cuts the requirement to about 40 mpg by 2026. Trump has also revoked a waiver that allowed California to set stricter standards, which are followed by several other states. The Trump administration contends its rule will save consumers billions of dollars in vehicle costs and will spur a move to new, cleaner and safer vehicles. Opponents say the rule will endanger public health and accelerate climate change by putting into the air more pollutants and greenhouse gases that cause global warming, especially carbon dioxide. The battle over the standards has divided automobile manufacturers and led a coalition of states headed by California, along with a dozen environmental groups, to sue to block the Trump administration's fuel efficiency and emissions rollback.
