WASHINGTON, DC - A broad coalition today urged Congress to reject four Congressional Review Act resolutions that would overturn long-standing Clean Air Act preemption waivers relied upon by states to protect public health and air quality.
Clean Transportation
Clean Transportation
Revolutionizing our transportation systems is a crucial piece of Sierra Club's work to ensure we all can live in healthy communities, move around safely, and build a future powered by renewable energy.

What is clean transportation?
We all want to breathe clean air and protect our families from toxic pollution and climate change. Unfortunately, transportation is currently our nation's largest source of greenhouse gas emissions and a major source of air pollution. To build a livable future, we must shift away from fossil fuel-powered vehicles and towards clean, renewable transportation.
Right now, Donald Trump and Republicans in Congress want to make it harder to drive clean cars, which will increase how much money you spend at the pump. We can stop them, but we need your help to protect access to public transportation, electric vehicles, and other clean transportation options.
Over the lifetime of the vehicle, a gas car puts out 4.5x more carbon pollution and infinitely more toxic tailpipe air pollution than an electric car.
Why is clean transportation essential?
We all want to breathe clean air and protect our families from toxic pollution and climate change. Unfortunately, transportation is currently our nation's largest source of greenhouse gas emissions and a major source of air pollution. To build a livable future, we must shift away from combustion vehicles and towards clean transportation.
Victory!
In a landmark legal win for clean transportation, a federal court has permanently barred the Trump administration from freezing funds for the National Electric Vehicle Infrastructure (NEVI) program – that is, a $5 billion federal initiative to build reliable, high-speed electric vehicle charging stations along America's highways!
The ruling means all 50 states, Washington, DC, and Puerto Rico now have the legal certainty they need to move forward building a nationwide charging network, free from unlawful interference. Sierra Club and partners brought this case on behalf of members who were directly harmed by the freeze.
This is what people power looks like: Sierra Club members standing up to protect clean transportation investment, cleaner air, and better access to affordable electric vehicle driving for everyone.
Press Releases
NATIONWIDE — New sales data shows that Toyota’s plug-in hybrid vehicle (PHEV) sales are increasing due to the automaker expanding availability of the PHEV models to dealers across the country.
Riverside, CA - The Sierra Club, Rural Association of Mead Valley (RAMV), and Industrial VI Enterprises have reached a settlement agreement over the controversial 1+ million-square-foot warehouse approved for construction in Mead Valley, Riverside County, known as the Cajalco Commerce Center.
WASHINGTON, DC — The U.S. Environmental Protection Agency transmitted two additional California waivers to Congress, including the Ocean-Going Vessels At Berth and Commercial Harbor Craft waivers. For 50 years, the precedent set under both Democratic and Republican administrations is that Clean Air Act waivers are not rules and are therefore not subject to review under the Congressional Review Act (CRA). EPA’s move to reclassify them is not only a misuse of CRA, but an unlawful and reckless attack on vital clean air protections.
WASHINGTON, D.C. — Today, House Republican Representative Harriet Hageman introduced legislation under the Congressional Review Act (CRA) to revoke California's Clean Air Act waiver allowing the state to enforce stronger than federal greenhouse gas standards for vehicles.
WASHINGTON, D.C. — Today, Trump’s Environmental Protection Agency released a proposal that would weaken clean truck pollution standards that protect Americans from dangerous air pollution.
WASHINGTON, D.C. - Yesterday, the Sierra Club joined partners in opposing the Trump EPA’s proposal to weaken vehicle pollutant standards by delaying the implementation of more protective standards by two years.
Barstow, CA — A coalition of conservation and environmental justice groups sued the city of Barstow today for approving a 5,000-acre rail yard and warehouse project that will worsen already poor air quality and destroy desert habitat without performing the required environmental reviews.The July 1 lawsuit, filed in San Bernardino County Superior Court, asserts that the city failed to evaluate and mitigate the project’s multiple environmental harms and violated the California Environmental Quality Act.
SACRAMENTO - Yesterday, California leaders reached an agreement in the state budget to provide new funding for zero-emission vehicle (ZEV) incentives for light- and heavy-duty vehicles. This agreement will reaffirm California’s role as a national leader on clean transportation, as the Trump administration continues attacking policies that help Americans afford cleaner vehicles and cut dependence on volatile gas prices.
NATIONWIDE – Today, Sierra Club, the Electrification Coalition, Forth, Plug In America released the latest edition of the AchiEVe policy guide, a comprehensive resource designed to help advocates, policymakers, utilities, and community leaders accelerate the transition to electric transportation through proven state, local, and utility policies.
