Clean Air Conservancy

The Clean Air Conservancy is a United States non-profit organization founded in 1992 as INHALE (National Healthy Air License Exchange) by Cleveland lawyer David B. Webster, dedicated to protecting clean air and slowing climate change through pollution markets and emissions trading. Based in Cleveland, Ohio, it pioneered the concept of permanently retiring pollution rights by transferring them into a trust, retiring nearly 9 billion pounds of pollution since inception. It participated in the first major sale of sulfur dioxide allowances on the Chicago Board of Trade under EPA mandates and has led in guiding pollution markets.
