In an interview with Fox News host Bill O’Reilly, GOP presidential nominee Donald Trump touted his “many environmental awards” while dismissing that human activity causes climate change.

“I want clean air and I want clean water,” Trump insisted. “I’ve gotten many environmental awards. Believe me, I know what I’m talking about. We have to have crystal clear water and crystal clean air.” He did not elaborate on what policies he would support as president to ensure clean air and water.

Trump said fossil fuels and human activity could have a “minor impact” on climate change, “but nothing to what they’re talking about.” He said efforts to reduce greenhouse gas emissions are “putting us at a tremendous disadvantage as a country because other countries are not adhering to the rules, we are, and it makes it impossible for our businesses to compete. We are adhering to these very strict rules and you look at China and you look at all of these other countries, practically all of them, they’re not adhering to the rules and our jobs are being… taken away.”

On the campaign trail, Trump has said he would oppose a carbon tax, pull the U.S. out of the Paris Agreement, while reviving the coal industry.
