Disposing of ozone- and climate-damaging substances from cooling appliances in an environmentally friendly way

Project description

Title: Climate and Ozone Protection Alliance for ODS and HFC Banks Management (COPA)
Commissioned by: German Federal Ministry for Economic Affairs and Climate Action (BMWK)
Country: Global, China, Ghana, Tunisia, Mexico
Partner: United Nations Industrial Development Organization (UNIDO), United Nations Development Programme (UNDP)
Lead executing agency: Ministry of Environment, Science, Technology and Innovation (MESTI), Ghana; National Ozone Unit, Environmental Protection Agency (EPA), Ghana; Ministry of Environment Protection/Foreign Economic Cooperation Office (MEP/FECO), Beijing, China
Overall term: 2013 to 2024



Demand for cooling and air conditioning units is rising sharply in the Global South. As a result, there is an ever-growing number of appliances and foams containing halogenated hydrocarbons. These are either ozone-depleting substances (ODS) or have a high global-warming potential (hydrofluorocarbons, HFCs). When old cooling devices are not disposed of in an environmentally friendly way, the legacy ‘ODS and HFC banks’ release emissions freely into the atmosphere.

The disposal of ODS and HFC banks is not currently a priority in the international climate debate. To date, the international community has only agreed to regulate the production and consumption of ODS in the Montreal Protocol and to phase-down climate-warming HFCs in the Kigali Amendment. An agreement on how to dispose of existing ODS and HFCs is still needed.


Policy-makers are taking measures to get rid of ODS and HFC banks and thereby reduce greenhouse gas emissions. They are also incorporating this issue into their national climate strategies.

The Climate and Ozone Protection Alliance (COPA) is combating emissions from old cooling devices in China and Ghana.

As the project progresses, more countries demonstrating considerable potential for reducing ODS and HFCs will be identified and supported. As part of this, the plan is to expand networks and to establish the Alliance in the countries concerned at political level.

COPA is focusing above all on working with metropolitan regions, as this is where large quantities of legacy ODS and HFCs build up.

In terms of putting reduction measures into practice, COPA carries out status quo analyses and implements practical models in selected metropolitan regions.
