Since March, Trump's EPA has left the Children's Health Protection Advisory Committee (CHPAC) partially unseated and inactive—weakening the agency's ability to keep kids safe from exposure to pollution, toxic chemicals, and microplastics.

Today, the Trump administration finalized a rollback of fuel economy standards for passenger cars and trucks. This move effectively kills the nation's CAFE standards, a program that has saved drivers $321 billion in fuel costs since 2010. Read UCS Statement: act.ucs.org/46NApCk

“The federal government’s decision to gut fuel economy standards is a handout to automakers and oil companies that will strap American consumers already struggling with an affordability crisis...Weakening these standards means drivers will spend more on fuel while having fewer options to choose efficient vehicles."

The speed, scope, and severity of attacks on the environment have been relentless. Here’s a quick recap of what President Trump and his “polluter worker bees” have accomplished on behalf of the fossil fuel industry:

Infographic titled “Trump’s Polluter Worker Bees,” featuring a black-and-white photo of Donald Trump at the top and five smaller portraits arranged below. The profiles identify Lee Zeldin, Doug Burgum, Chris Wright, David Fotouhi, and Nancy Beck alongside their Trump administration positions. Brief text summarizes each person’s past ties to fossil fuel, chemical, or other regulated industries and describes environmental policies or actions attributed to them. The design uses black, white, red, and gold, with each portrait framed by a gold hexagon.

For the next year, we can expect to see precipitation and other weather extremes unlike anything we’ve seen before. Why? When the oceans are warmer, thanks to climate change and the developing El Niño, they release vast amounts of moisture into the atmosphere, which act as extra fuel for any storm.
