What Are Hydrofluorocarbons?

HFCs: Super Greenhouse Gases

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.

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.

Major Climate Win: Lessons for the Montreal Protocol
02/10/2021
Two new papers published in Nature suggest that the CFC-11 emissions are back on a downward trajectory potentially avoiding substantial delays in the recovery of the ozone layer. The papers show an accelerated decline in global atmospheric concentrations of CFC-11 from 2018 to 2019, and attribute 60% of the decline to China. This is a huge win for the ozone layer and our climate, which would not have been possible without a concerted global response to the findings from the ground and the atmosphere.

Today, Walmart investors voted on the first-ever shareholder resolution on refrigerants and their related climate impacts. The initial count indicates 5.5 percent of investors voted in favor of the proposal filed by Rhode Island Treasurer Seth Magaziner, urging Walmart to disclose how it will limit its impact on climate change by increasing the scale, pace, and rigor of its plans to significantly scale back hydrofluorocarbons (HFCs) used in its operations.
