Democrats are committed to curbing the effects of climate change, protecting America’s natural resources, and ensuring the quality of our air, water, and land for current and future generations. From investing in clean energy to protecting our ecosystems, Democrats are working to address our biggest environmental challenges, paving the way to a more sustainable America.

Under President Obama, we made great strides to combat climate change and protect our environment and public lands. The Department of Transportation and the EPA issued new fuel-economy standards, the first meaningful increases in fuel economy for cars and light trucks in decades. President Obama instructed the Environmental Protection Agency to take steps to regulate carbon dioxide emissions from coal-fired power plants, which are the largest concentrated source of emissions in the United States. Under Donald Trump, the United States stands alone as the only nation in the world that is not a party to the Paris Climate Agreement.

Democrats want to protect and build on President Obama’s progress. We know that climate change is one of our nation’s greatest challenges, and that addressing this urgent threat could make America the world’s clean energy superpower and create millions of good-paying jobs. Democrats will fight to protect our planet for future generations.

Donald Trump, on the other hand, has called climate change “a hoax invented by the Chinese,” and withdrawn from the Paris Climate Agreement. And by choosing to ignore the consensus of the scientific community on climate change, he is putting our country’s health, security, and economy at risk.

It will take all of us acting together — workers and entrepreneurs, scientists and citizens, the public and the private sector — to address the challenge of climate change and seize our clean-energy future.
