The National Ozone Unit (Division for Protection of the Ozone Layer and Management of Fluorinated Gases) is a unit under the Climate Change and Adaptation Department of the Ministry of Environment and Urbanization in Turkey. The National Ozone Unit is responsible for coordinating national programs for the requirements of the Montreal Protocol on Substances that Deplete the Ozone Layer, to which our country was a party in 1991.

National Ozone Units have various responsibilities such as overseeing the national adaptation strategy, collecting and reporting data, monitoring and facilitating national projects approved by the multilateral fund, developing and implementing policies and legislation, and coordinating and interacting with Implementation Agencies (UNIDO, UNDP, UNEP etc.) and carrying out awareness raising activities.

Ozone Officers and teams working in the National Ozone Units are at the national level in the "driver's seat" of the Montreal Protocol process and they are the focal points of implementation issues related to this multilateral environmental agreement.
