Tell Trump: Don't pull out of Paris Climate Agreement

President Trump: We urge you keep the United States in the Paris Agreement.

Why is this important?

The Trump Administration is considering pulling the United States out of the Paris Agreement, currently the world’s best chance at slowing climate change.

The Paris Agreement is an agreement dealing with greenhouse gases emissions mitigation, adaptation and finance starting in the year 2020. The language of the agreement was negotiated by representatives of 195 countries at the 21st Conference of the Parties of the UNFCCC in Paris and adopted by consensus.

Climate change may be the most important challenge humanity has ever faced. The Paris Agreement -- ratified last year -- stands as an unprecedented global pact among 196 nations to take steps to prevent catastrophic climate change and ensure a cleaner, safer planet for future generations.

U.S. participation in the agreement deserves our support more than ever to ensure it remains strong.

The Obama administration had promised the world that the United States would reduce its emissions by 26 to 28 percent below its 2005 levels by the year 2025.

If the United States pulls out it will effectively be the end of the agreement.
