COLORADO - Arguing that the Polis Administration’s unnecessary delay in considering new rules to clean up truck pollution will only lead to more harm to families and communities in disproportionately impacted areas of Colorado, a coalition of environmental justice, conservation, local government and other groups today formally petitioned the Colorado Air Quality Control Commission (AQCC) to consider an Advanced Clean Trucks rule and a low NOx rule this spring.

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.
