Air Conditioning and Refrigeration






Air conditioning and refrigeration equipment allow us to keep cool during hot summer days and to keep our food fresh all year long but they also can contribute to depletion of the stratospheric ozone layer and to climate change. This site was developed to help increase one's understanding and knowledge of the regulations under the Clean Air Act that apply to the manufacturing, sale, servicing and disposal of air conditioning and refrigeration equipment as well as to provide information on how to reduce the overall environmental footprint of this equipment. For any questions/concerns, please call EPA Region 2's Compliance Assistance Hotline at (212) 637-4050.

In the Spotlight

North America Collaborates to Reduce and Replace Potent Greenhouse Gases

During the phaseout of chlorofluorocarbons (CFCs) under the Montreal Protocol and the Clean Air Act, manufacturers of equipment such as car air conditioners and kitchen refrigerators substituted hydrofluorocarbons (HFCs), which are up to 14,000 times more damaging to the Earth’s climate system than carbon dioxide. As a result, Canada and Mexico have joined the United States in proposing to expand the scope of the Montreal Protocol to phase down not only substances that deplete the stratospheric ozone layer but also HFCs. This proposal is expected to provide environmental benefits equal to removing greenhouse gas emissions from 59 million passenger cars each year through 2020, and 420 million cars each year through 2050.

EPA Proposes to Allow HFO-1234yf as a New Substitute Refrigerant

The European Union has banned the use of HFC-134a (the current MVAC refrigerant) effective 2011. U.S. car manufacturers are developing systems using HFO-1234yf, a flammable refrigerant, for the European market and for possible domestic sale as well. This proposed rulemaking will allow for the safe introduction, operation and maintenance of HFO-1234yf in the United States. More Information.

Businessman Convicted for Evading $1.9 Million in Taxes on Sales of Ozone-Depleting Greenhouse Gases

Dov Shellef, a businessman from Great Neck, N.Y., was convicted on 86 counts, following a five-week jury trial, for conspiring to defraud the Internal Revenue Service in the collection of approximately $1.9 million in excise taxes due on sales of the ozone-depleting greenhouse gas known as CFC-113. The jury sitting in Central Islip, N.Y., also convicted Shellef for subscribing to false corporate tax returns, wire fraud and money laundering. Shellef faces a maximum prison sentence of five years for the conspiracy, three years for the false corporate tax return, 20 years for the wire fraud convictions and 20 years for the money laundering convictions.

EPA Making It Easier to Access the UV Index to Promote Sun-Safe Behaviors

As millions of families prepare to enjoy the great outdoors this summer, EPA wants to remind everyone to practice sun-safe behaviors to reduce exposure to harmful ultraviolet (UV) radiation. The UV Index, developed by the National Weather Service and EPA, indicates the strength of solar UV radiation on a scale from 1 (low) to 11+ (extremely high) to help families make decisions on the appropriate level of sun protection. EPA has made use of new technology to make the UV index easier to access. Not only is the UV index published every day on EPA's Website, one can also sign up to receive e-mails with your area’s UV Index, download the EPA's UV Index application on your smartphones, and/or incorporate a UV index widget on your website.
