Cold Hard Cash for Your Greenhouse Gas

Refrigerants being used in old air conditioners or grocery story cooling systems leak into the atmosphere contributing to global warming. Tradewater, a company in Illinois, picks up these containers, destroys the refrigerants, gives them cash, and then sells them as carbon offset credits. They collect up to 250,000 pounds of refrigerants per year, but there is still more out there. Supermarkets in the United States could switch to more natural refrigerants, but barely 1 percent are known to have done that. Getting rid of these refrigerants can be an important solution to combating climate change.
