Office of Atmospheric Programs (OAP)

EPA's Clean Air Markets Division (CAMD) includes several market-based regulatory programs designed to improve air quality and ecosystems. The most well-known of these programs are EPA's Acid Rain Program and the NOx Programs, which reduces emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) compounds that adversely affect air quality, the environment, and public health. CAMD also plays an integral role in the development and implementation of the Clean Air Interstate Rule (CAIR) and the Clean Air Mercury Rule (CAMR).

EPA's Stratospheric Protection Division (SPD) protects human health and the environment by restoring the earth's protective ozone layer. SPD implements the requirements of Title VI of the Clean Air Act, which is the legal framework for U.S. compliance with the Montreal Protocol on Substances that Deplete the Ozone Layer. SPD also promotes advanced technologies and the responsible use of non-ozone depleting chemicals to minimize impacts on human health while we work to restore the ozone layer, and SPD also educates Americans to be SunWise by avoiding overexposure to solar ultraviolet radiation.

EPA's Climate Change Division (CCD) is the EPA lead on domestic and international climate change policy. CCD pursues programs to further the Administration's broader climate policy and objectives. Some of the division's main functions include: compiling and reporting the U.S. greenhouse gas inventory under the United Nations Framework Convention on Climate Change (UNFCCC); managing several non-CO2 voluntary programs such as the Landfill Methane Outreach Program, and the international Methane to Markets Partnership; tracking emerging issues in climate science, impacts, economics and innovative technologies; and supporting U.S. bilateral and multilateral partnerships.

EPA's Climate Protection Partnership Division (CPPD) promotes greater use of energy efficient products and practices in the residential, commercial and industrial sectors through the ENERGY STAR partnership program. The Division's programs such as Climate Leaders provide information, technical assistance, and recognition for environmental leadership to organizations as they develop strategies and take advantage of proven opportunities to reduce their GHG emissions. CPPD also encourages investments in efficient, clean technologies such as combined heat and power (CHP) and green power from renewable resources.
