HFCs or hydrofluorocarbons, are super greenhouse gases, manufactured for use in refrigeration, air conditioning, foam blowing, aerosols, fire protection and solvents. HFCs unlike most other greenhouse gases are not waste products but are intentionally produced. HFCs were developed as alternatives to ozone depleting substances that are being phased-out under the Montreal Protocol. Unfortunately, HFCs have a global warming potential 1000 to 3000 times that of CO2, and their use has increased from almost nothing in 1990 to 1,100 million tonnes of CO2e in 2010. HFC emissions (excluding HFC-23 by-product) currently account for around 1% of global greenhouse gas emissions and as much as 3% in many developed countries. If left unchecked, these emissions will increase to 7-19% of all greenhouse gas emissions by 2050 and off-set most if not all mitigation actions pledged by countries to date.
What Are Hydrofluorocarbons?
HFCs: Super Greenhouse Gases
Do We Have to Use These Climate-Destroying Gases?
No! HFC-free technologies are currently available, and more are coming on-line every year so that most uses could be phased-out by 2020 and the remaining uses by 2030. Some of the currently available climate-friendly alternatives include hydrocarbons, ammonia (R- 717), water and carbon dioxide (CO2 or R-744). Other alternatives refrigerants, such as isobutane (R-600a) propylene (R-1270); and not-in-kind alternatives, such as solar, are also likely to be commercialized and enter the market in the next few years. EIA works to encourage transitions by working with supermarkets, breaking down barriers to change in all industries, and by encouraging domestic actions.
