The country’s leading lobbying arm for oil refiners doesn’t want President-elect Joe Biden to rule out working with its members on policies to curb greenhouse gas emissions.

Biden, who is promising the most aggressive agenda on climate change of any president, could see a reason to doubt the climate credentials of the American Fuel and Petrochemical Manufacturers, which represents petroleum refiners and petrochemical makers. Oil is built into the fabric of their industry, and Biden is pledging to reduce the United States’s reliance on fossil fuels to reach net-zero emissions across the economy by 2050.
