It is a man-made substance used primarily as a refrigerant. When released into the environment, CFC-13 has a high ozone depletion potential, and long atmospheric lifetime. [2] Only a few other greenhouse gases surpass CFC-13 in global warming potential (GWP). [3]: 2 The IPCC AR5 reported that CFC-13's atmospheric lifetime was 640 years. [4]
In the United States, the regulation of F-gases falls under the authority of the Environmental Protection Agency's overall attempts to combat greenhouse gases. [7] The United States has put forward a joint proposal with Mexico and the Federated States of Micronesia for a phase-down of HFCs by 2030.
HFO-1234yf was developed by a team at DuPont, led by Barbara Haviland Minor, jointly with researchers at Honeywell. [8] [9] Their goal was to meet European directive 2006/40/EC, which went into effect in 2011 and required that all new car platforms for sale in Europe use a refrigerant in its AC system with a global warming potential (GWP) less than 150 times more potent than carbon dioxide.
While new production of these refrigerants has been banned, large volumes still exist in older systems and have been said to pose an immediate threat to our environment. [56] Preventing the release of these harmful refrigerants has been ranked as one of the single most effective actions we can take to mitigate catastrophic climate change. [57]
