Nike, The North Face, Vans, Patagonia, K2 Sports, Clif Bar and OIA were among more than 300 businesses across industries signing a letter urging president-elect Donald Trump and other world leaders to remain committed to the Paris agreement on climate change.

The letter was addressed to “President-elect Trump, President Obama, Members of the U.S. Congress, and Global Leaders at COP22 in Marrakech.” The letter was announced in a press conference during the 22nd session of the Conference of the Parties (COP 22) currently being held in Morocco.

The future president has claimed climate change is a hoax and vowed on the campaign trail to pull the U.S. out of the historic Paris Climate Agreement.

The letter read, “We want the U.S. economy to be energy efficient and powered by low-carbon energy. Cost-effective and innovative solutions can help us achieve these objectives. Failure to build a low-carbon economy puts American prosperity at risk. But the right action now will create jobs and boost U.S. competitiveness. We pledge to do our part, in our own operations and beyond, to realize the Paris Agreement’s commitment of a global economy that limits global temperature rise to well below 2 degrees Celsius.”

They added, “Implementing the Paris Agreement will enable and encourage businesses and investors to turn the billions of dollars in existing low-carbon investments into the trillions of dollars the world needs to bring clean energy and prosperity to all.”

The 175 signatories to the non-binding treaty, including the U.S., are committed to reducing the emission of greenhouse gases as a way of fighting climate change.
