 We're a nonprofit trade association that helped the industry in the proper use and disposal of refrigerants. So we literally work with the federal government, the EPA, on how they write the laws on handling refrigerant contaminants. Because as we know, refrigerant was one of the big contributors to the ozone hole. That's why R-12 got outlawed and it got replaced by 134A, which still did some damage to the ozone hole.
