From nationwide #EV charging to pollution-free buses, trucks, biking, and walking: these investments save money and lives. Congress must protect and expand them, not roll them back. Let’s keep building a cleaner, more affordable transportation system. 👏 #ChargingUSForward

Grateful to @markey.senate.gov for defending fuel economy standards that protect consumers, public health, and our climate. Rolling them back only raises costs. Thank you for fighting for cleaner, cheaper transportation. #CleanerCars #RouteZero

Thank you @davids.house.gov for pushing back on attacks on federal fuel economy standards. These rules save drivers thousands, cut pollution, and strengthen U.S. energy security. #CleanerCars #RouteZero

Thank you, @dorismatsui.bsky.social, for standing up for strong fuel-economy standards that save families money, cut pollution, and reduce oil dependence. Clean transportation is affordable transportation. #CleanerCars #RouteZero

💰🚗For more than a half century, fuel efficiency standards have saved US drivers money. How much money? TRILLIONS. Fuel efficient vehicles mean less expensive trips to the gas pump and more money for education, for family outings, for groceries. (🧵👇)

🚍🌍 UCS is keeping an eye on the Surface Transportation Reauthorization(STR) because it shapes how the US moves—and who benefits. For decades, highway projects have divided and polluted communities. It’s time for a better approach.

The Trump agenda is sending energy prices skyrocketing.

Even worse, his Big-Beautiful-for-Billionaires Bill will drive your power bills even higher.

Today marks day 1 of public hearings on the EPA’s reconsideration of the endangerment finding, a 2009 declaration that greenhouse gases threaten public health. Follow along with us👇🧵

Ready for Work 2.0 Electrifying our on-road freight system is the surest way to reduce truck pollution and improve air quality.

Electric trucks & buses = reduced climate-warming pollution & poor air quality. Thankfully, key policies can accelerate adoption. EPA’s Clean School Bus Program TRIPLED electric school bus deployment in the US. Learn more about MHDV deployment here:

We noticed something important when the administration was announcing they don’t want to regulate heat-trapping emissions. You can see more about the link between climate change and the extreme weather we see here:

Railroads Are Running Dirty Diesel Trains Through Communities and No One Is Doing Anything About It The case for rail electrification is clear in the benefits to the economy, public health, and environment.

Think rail is a clean transportation source? Think again. 🤔 UCS Senior Vehicles Analyst explains why and how the rail industry has hindered progress in emission reduction over the past decade:

Sen. Markey, Rep. Deluzio Introduce Legislation to Transform U.S. Rail Network | U.S. Senator Ed Markey of Massachusetts All Aboard Act dedicates $200 billion over five years to build transportation system of the...

🚂Yesterday, @markey.senate.gov and @deluzio.house.gov reintroduced the transformative All Aboard Act, which would dedicate billions of investments to modernize our nation’s rail, reducing locomotive emissions and securing critical labor protections:

Today, the EPA released a proposal that would gut the 2009 Endangerment Finding. “These actions by Lee Zeldin are anti-science and backed by the fossil fuel industry, said Chitra Kumar, Managing Director, UCS Climate & Energy campaign.

A person leans into the back seat of a black Uber car, seen from the outside. Overlaid on the image is a quote in white text: “Everybody will say, ‘Silicon Valley’s reinventing the bus again,’ but it’s more like [Uber is] reinventing a worse bus.” —Kevin Shen, Transportation Policy Analyst.

Uber’s new Route Share shows people want affordable, flexible options—but it falls short and worsens climate impacts. What if we met that demand sustainably, by investing in public transit🚍, safe bike lanes, and walkable routes to get where we need to go?

A reprieve for the USPS trucks:

The Senate parliamentarian ruled overnight that this provision violates the rules of budget reconciliation

It **cannot** appear in Trump and Republicans’ “One Big Beautiful Bill.”

California Leads States in Suing the Trump Administration Over Its Revocation of Air Pollution Standards California and ten other states are suing the Trump administration over its revocation of three waivers that let California set standards to improve air quality, reduce climate-warming emissions and p...

🚨 Last week CA and 10 other states announced plans to sue the Trump Admin for their illegal attempt to repeal 3 clean air safeguards. @governor.ca.gov responded with an EO reaffirming CA’s commitment to a clean vehicle transition. 👏 Kudos to Gov Newsom for keeping CA moving forward.

For Trump, This Is a Dress Rehearsal Ordering the National Guard to deploy in Los Angeles is a warning of what to expect when his hold on power is threatened.

1/ The Trump administration is turning our government into a weapon to attack families and undermine our fundamental rights and freedoms. Its tactics of escalating violence against migrant communities in Los Angeles are deeply concerning and signal a further slide into authoritarianism.

Hurricane season started last weekend—and acting FEMA head David Richardson reportedly told staff he didn’t know the US had one. Clueless? Joking? Either way, the guy running US disaster response is giving big Michael Scott energy—and that’s really bad. Some comments from his tenure:

Car swerving meme Car labeled "Republican budget bill" swerving away from "helping ordinary Americans" lane into "Banning clean energy, cutting taxes for billionaires, raising costs for ordinary Americans" off-ramp.

Call your senators at 202-224-3121 and tell them to stop the #BillionaireTaxScam 🗣️

Republicans want to overturn half a century of precedent to undermine California’s ability to protect the health of our residents.

Why?

Because to them, it’s more important to appease big oil than it is for your kid to breathe clean air.

Why Does Toyota Oppose Clean Air? There is no way to protect our health and our climate by simply making better gasoline cars.

Toyota has joined fossil fuel companies in asking the US Senate to prevent California from taking necessary steps to slow climate change and protect its residents from air pollution that is making people sick and shortening lives.

Learn the details in UCS's David Reichmuth's blog.

Opinion | What if Republicans Ditch the Senate’s Rules? If they can ignore the parliamentarian on electric vehicles, why not on their tax bill? On healthcare? On the president’s latest overreach?

"For a party so dedicated to protecting the filibuster, Republicans are going to extreme lengths to undo California’s Clean Air Act waivers." Op-ed from Senator Padilla: www.wsj.com/opinion/what...

Brochure reads "The Advanced Clean Cars Program Creates Good Jobs in California. Over a quarter of a million people are now employed by our EV industry. The growth in charging infrastructure alone will create even more valuable union electrical jobs and skilled training opportunities. We are ready to power millions of zero-emission cars, trucks, and buses. Defend our EV jobs! Support California's clean car standards!
