Hydrofluorocarbons Get Squeezed by California Air Regulators

摘要

The California Air Resources Board on Thursday approved new limits on hydrofluorocarbons, thepotent greenhouse gases used in refrigeration, air conditioning, ice rinks, and other operations.New stationary refrigeration units with more than 50 pounds of refrigeration must not exceed aglobal warming potential of 150, under the amended state regulations. For new stationary airconditioning, the limit is set at 750. A global warming potential of 1 is equal to the emission of akilogram of carbon dioxide, which is calculated by Intergovernmental Panel on Climate Change.Retail food companies also will also have to create company-wide emissions reduction targets.
