BOSTON— The Center for Biological Diversity Action Fund and Oil Change Action, the 501(c)(4) political arm of the Center for Biological Diversity and Oil Change International respectively, announced today its endorsement of incumbent Sen. Ed Markey from Massachusetts for reelection to the U.S. Senate.
“Sen. Markey has long been one of Congress’ most visionary and relentless champions for clean air and water and our shared natural heritage,” said Brett Hartl, national political director at the Center for Biological Diversity Action Fund. “He’s been an extraordinary environmental leader who takes bold action and isn’t afraid to stand up to bullies like Trump and his extremist allies in Congress. We’re honored to endorse him and excited to watch him amp up the fight.”
Throughout his career in Congress — first as a U.S. representative and then as a senator — Sen. Markey has championed groundbreaking climate and environmental legislation, including co-authoring the Green New Deal. His leadership has helped advance critical policies to strengthen environmental protections, hold corporate polluters accountable, and safeguard public lands and imperiled wildlife.
“Sen. Ed Markey is one of Congress’s leading champions on climate and environmental justice,” said Allie Rosenbluth, U.S. campaign manager at Oil Change Action. “He has fought to end massive government giveaways to the fossil fuel industry, unmask gas industry greenwashing, and stop the reckless buildout of U.S. liquified natural gas exports, which raise households’ utility bills and worsen the climate crisis. We are proud to endorse Sen. Markey to continue to fight for people and the planet in the Senate.”
Sen. Markey received a 100% lifetime score on the Action Fund’s environmental scorecard, meaning he has taken the pro-environmental stance on every vote scored.
Rep. Seth Moulton (MA-06), who is challenging Sen. Markey for the Democratic nomination, received a 77%. In 2023 Moulton voted for legislation that included approving the Mountain Valley Pipeline, an ecological and climate disaster that threatens one of the largest remaining wild landscapes in the eastern United States. Sen. Markey voted against the bill.
Moulton also failed to support the Environmental Justice for All Act, one of the most comprehensive environmental justice bills in history. Sen. Markey was one of the original cosponsors of the Senate bill.
