Little cans make a big difference

• The current automotive refrigerant (R-134a) is a highly potent greenhouse gas.
• Just the gas contained in one single 12-ounce container is equivalent to the carbon dioxide (CO₂) emissions from burning 150 gallons of gasoline!
• The gas from two 12-ounce containers, if released into the atmosphere, will cause the same global warming pollution as driving all the way across the country diagonally, from Los Angeles to New York.
