Ozone Depleting Substances

Most of the old refrigerators and air conditioners still use refrigerants consisting of ozone depleting substances (ODS) such as hydrochlorofluorocarbons (HCFCs) with a very high global warming potential (GWP). Due to the Montreal Protocol, production and consumption of ODS have been successfully reduced stepwise. However, the environmentally friendly management of so-called ''ODS banks'' (waste containing these substances such as old fridges, air conditioners, etc.) is not regulated by the Montreal Protocol and often not properly handled. As a consequence, the substances are leaking from ODS banks into the environment, damaging the ozone layer and global climate. Adequate collection, recovery and destruction of ODS banks is a real challenge for developing countries. Often they lack the institutional framework conditions, related waste management planning and infrastructure as well as specific technologies for ODS destruction.

As part of the International Climate Initiative (IKI) of the Federal Ministry for Environment, Nature Conservation, Building and Nuclear Safety (BMUB), GIZ Proklima carries on the first global project on ODS waste management dedicated to the development and implementation of integrated strategies for reducing the emissions of ODS containing waste. It supports selected cooperation countries in the five UN regions to develop an integrated approach for management and destruction of ODS.
