More than 1,000 businesses and organizations have signed a letter urging Congress to defend and strengthen the Energy Star labeling initiative for efficient appliances that is maintained through the U.S. Environmental Protection Agency.The group, organized by the Alliance to Save Energy, says the program saves consumers more than $34 billion per year in reduced energy costs. President Trump's proposed budget eliminates funding for Energy Star, a voluntary program with an annual budget of about $50 million.The EPA budget overall would be cut 31% under the proposal. Energy Star is a curious victim of the Trump administration's slash-and-burn approach to the EPA: It's a voluntary program with bipartisan support and a small budget, and pretty much everyone agrees it works.Why kill it? CNN has a possible answer: Trump properties score poorly in Energy Star ratings. The news organization said scores from 2015 show 11 of 15 Trump properties in major cities are less efficient than comparable buildings.The Trump condominiums at 610 Park Avenue in Manhattan rate a 1, the lowest possible Energy Star rating, CNN said.Now, more than 1,000 businesses and organizations, including national and regional chains, universities, and Habitat for Humanity, are urging lawmakers to fight for the program, calling it "a model for successful collaboration between the public and private sectors."
