What is Being Done About the Depletion of “Good” Ozone?
In the United States, the U.S. Environmental Protection Agency continues to establish regulations to phase out ozone depleting substances. The Clean Air Act requires warning labels on all products containing CFCs or similar substances, prohibits the release of refrigerants used in car and home air conditioning units and appliances into the air. Montgomery County has joined Cities for Climate Protection, a worldwide effort coordinated by the International Council for Local Environmental Initiatives (ICLEI). The county joins over 350 cities and counties working towards the reduction of local greenhouse gas emissions. Learn more about DEP’s Climate Protection Initiatives.

Currently, 160 countries participate in the Protocol. Efforts will result in recovery of the ozone layer in about 50 years. In the United States, the U.S. Environmental Protection Agency (EPA) continues to establish regulations to phase out these chemicals. The Clean Air Act requires warning labels on all products containing CFCs or similar substances, prohibits nonessential ozone depleting products, and prohibits the release of refrigerants used in car and home air conditioning units and appliances into the air. BAD NEARBY What Causes “Bad” Ozone? Motor vehicle exhaust and industrial emissions, gasoline vapors, and chemical solvents are some of the major sources of NOx and VOC, also known as ozone precursors.
