The Service Employees International Union has become the first U.S. labor union to support the Green New Deal. On Thursday, SEIU’s executive board voted to endorse the plan to radically shift the U.S. economy to renewable energy, ending U.S. carbon dioxide emissions by 2030. In a tweet, SEIU said, “This groundbreaking measure aims to address climate change while creating high-quality union jobs. We need to combat climate change while raising standards for all working people.”
