California introduces groundbreaking program to reduce climate “super pollutants”
SACRAMENTO – Today the California Air Resources Board approved first-in-the-nation rules to curb the impact of powerful artificial refrigerants that pose a growing danger globally to efforts to contain the worst impacts of climate change.
The refrigerants, known as hydrofluorocarbons or HFCs, are considered to be super pollutants because they trap heat in the atmosphere thousands of times more effectively than carbon dioxide, the most prevalent greenhouse gas. These rules can serve as a national model for super pollutant reduction.
