The SNAP program operates under Section 612 of the United States Clean Air Act. It reviews and analyzes alternative refrigerants based on their environmental and human health impacts, as well as the availability of reasonable substitutes. It can approve climate-friendly chemicals and prohibit certain uses of harmful ones.

PROJECTIONS FOR 2050
In response to the combination of growing demand and new regulatory challenges, the major refrigerant producers have created a number of blends of HFCs and new fourth-generation refrigerants called hydrofluoroolefins (HFOs).
Hydrocarbon (HC) refrigerants such as propane and isobutane, as well as other natural refrigerants such as ammonia and carbon dioxide, are garnering renewed attention. They have very low ozone-depletion potential and GWP, but they are either flammable (the HCs), highly toxic (ammonia), or require very high system pressures (carbon dioxide). In addition, the HCs are limited to a strict charge limit per circuit and are not SNAP-approved for use in retrofit applications.
Also likely will be the growth of hybrid systems that combine a natural refrigerant and a HFC/HFO blend in
a primary/secondary arrangement.
Although the SNAP program was originally created to address ozone depletion, it expanded its reach to target refrigerants that have a high global-warming potential (GWP). On July 2, 2015, the EPA announced that it was delisting many HFC refrigerants for a number of applications.
Although the regulations will be phased in over the next few years and systems that use HFCs can continue to be serviced for their useful life as long as supplies of the refrigerant exists, the end is in sight for HFCs as stand-alone refrigerants.

According to NASA, global temperature has risen 1.4°F since 1880. And according to the National Oceanic and Atmospheric Administration, results from a wide range of climate model simulations suggest that the planet’s average temperature could be between 2°F and 9.7°F warmer in 2100 than it is today.
HFCs are among the most potent of the heat-trapping “greenhouse gases.” According to the United Nations Environment Programme, HFC emissions are growing at a rate of about 7 percent annually.
...However, it wasn’t long before a new environmental menace was discovered: a gradual warming of the planet caused by an accumulation of heat-trapping gases in the upper atmosphere....
The overall demand for refrigerants, however, remains strong: according to the research firm MarketsandMarkets, global demand for refrigerants is expected to reach $21 billion by 2020, at a compound annual growth rate of 6.0 percent.
WHAT'S BEEN DONE SO FAR
The world of refrigerants has become a very complicated place. There is no “silver bullet” refrigerant and knowledgeable contractors and well-trained technicians will be more important than ever to meet the vital and growing need for efficient, effective, and environmentally safe air conditioning and refrigeration worldwide.
Potential emission reduction with
an HFC phasedown:
Under SNAP the EPA banned the use of CFCs and their close relatives the hydrochlorofluorocarbons (HCFCs). Those refrigerants were replaced by hydroflouorocarbons (HFCs), which do not harm the ozone layer.
THE FUTURE OF
The world of refrigerants used to be pretty simple: there was a refrigerant for air conditioning systems, and a refrigerant for refrigeration applications. However, scientific research implicated these chlorofluorocarbon (CFC) refrigerants as culprits in the depletion of the Earth’s protective ozone layer, and in 1996 the Environmental Protection Agency’s (EPA’s) Significant New Alternatives Policy (SNAP) program was born to encourage the development and use of environmentally safer refrigerants.
