SENATOR KEVIN CRAMER, NORTH DAKOTA REPUBLICAN:

"Today's ruling reaffirms Congress never intended the federal government to regulate greenhouse gas emissions for the states."

MICHAEL BLOOMBERG, U.N. SPECIAL ENVOY FOR CLIMATE AMBITION:

"This decision marks the second time in a week that the Supreme Court has turned back the clock to darker days that have dangerous implications for public health. The decision to side with polluters over the public will cost American lives and cause an enormous amount of preventable suffering, with the biggest burden falling on low-income communities and communities of color."

JODY FREEMAN, HARVARD UNIVERSITY LAW PROFESSOR

"This is a lifeline to extending the use of coal."

U.S. SENATE MAJORITY LEADER CHUCK SCHUMER, A DEMOCRAT

"Just like last week's dangerously misguided and abhorrent decisions on gun safety and abortion, the extremist MAGA Court's ruling today in West Virginia v. EPA will cause more needless deaths - in this instance because of more pollution that will exacerbate the climate crisis and make our air and water less clean and safe."

U.S. REPRESENTATIVE RAUL GRIJALVA, CHAIRMAN OF THE HOUSE NATURAL RESOURCES COMMITTEE

"With today's decision to gut the federal government's ability to keep carbon pollution from some of the country's biggest climate change offenders in check, they've sentenced our planet to death as well."
