Based on extensive technical analysis that shows automakers are well positioned to meet greenhouse gas (GHG) emissions standards for model years 2022-2025, U.S. Environmental Protection Agency (EPA) Administrator Gina McCarthy proposed leaving the standards in place, so the program that was established in 2012 will stay on track to nearly double fuel economy, dramatically cut carbon pollution, maintain regulatory certainty for a global industry, and save American drivers billions of dollars at the pump.
“Given the auto industry’s importance to American jobs and communities and the industry’s need for certainty well into the future, EPA has reanalyzed these clean car standards and sought further input,” said EPA Administrator Gina McCarthy. “It’s clear from the extensive technical record that this program will remain affordable and effective. This proposed decision reconfirms our confidence in the auto industry’s capacity to drive innovation and strengthen the American economy while saving drivers money at the pump and safeguarding our health, climate and environment.”
Today’s proposed determination is based on years of technical work, including an exhaustive technical report released earlier this year, and the agency’s thorough review and consideration of comments received on that report. This extensive body of analysis shows that manufacturers can meet the standards at similar or even a lower cost than what was anticipated in the 2012 rulemaking, and that the standards will deliver significant fuel savings for American consumers, as well as benefits to public health and welfare from reducing the pollution that contributes to climate change. Full implementation of the standards will cut about 6 billion metric tons of GHG emissions over the lifetimes of the vehicles sold in model years 2012-2025. Cars and light trucks are the largest source of GHG emissions in the U.S. transportation sector.
Although EPA’s technical analysis indicates that the standards could be strengthened for model years 2022-2025, proposing to leave the current standards in place provides greater certainty to the auto industry for product planning and engineering. This will enable long-term planning in the auto industry, while also benefiting consumers and the environment.
The announcement builds on years of success under EPA’s vehicle emission standards. Auto manufacturers are innovating and adopting fuel economy technologies at unprecedented rates. Car makers have developed more technologies to reduce GHG emissions, and these technologies are entering the fleet faster than expected. These technologies include gasoline direct injection, more sophisticated transmissions, and stop-start systems that reduce idling fuel consumption. At the end of 2015, all large automakers were in compliance with the standards. In fact, automakers on average out-performed the model year 2015 standards by seven grams per mile. These gains are happening at a time when the car industry is thriving, and domestic vehicle sales have increased for six consecutive years, while maintaining consumer choice across a full range of vehicle sizes and types.
As part of the rulemaking establishing the model year 2017-2025 light duty vehicle GHG standards, EPA committed to conduct a Midterm Evaluation of standards for model years 2022-2025. The public comment period for this action begins today and will end on December 30, 2016. After the comment period has ended and consideration of the input, the Administrator will decide whether she has enough information to make a final determination on the model year 2022-2025 standards.
