The HVACR industry, in which I spent much of my career, has been a leader in environmental progress. Since the 1970s, the industry has worked with Congress and the U.S. Department of Energy to promulgate minimum efficiency standards that make it illegal to manufacture and sell the least energy efficient heating and cooling systems. In the 1990s, industry participants worked cooperatively and with great success to find alternatives to refrigerants that were attacking the ozone layer. More recently, all sectors of the industry have been working to eliminate high global warming refrigerant gases from their new products. There have been legitimate business reasons for doing these things, but for the most part, it has been an industry that has done well by doing good.
