demonstrate the benefits of ODS destruction. Yet, action to recover and destroy CFC and HCFC banks in refrigera- tion and air-conditioning represent a cost-effective means of protecting the ozone layer and climate system, because the technology is available and the chemicals are reach- able (with the exception of insulation foams where destruc- tion is more complicated). Simply destroying the most cost-effective banks in refrigeration and air-conditioning units at end-of-life could accelerate the return of the ozone layer to its pre-1980 state. According to the graph below, the costs of avoiding a giv- en amount of GHG emissions by destroying ODS are lower than the average price of the same amount on the official carbon market. It is therefore cheaper to destroy ODS than to take other measures to avoid GHG emissions. Advocates of controlled destruction point out the unique opportunity to hit a double target and call for the allocation of funding to support developing (Article-5) countries in manag- ing and destroying their ODS banks. Quick action is need- ed because the longer we wait, the more ODS will escape uncontrolled into the air and reduce the potential benefits. Another measure providing quick results is to improve the efficiency of the equipment in place and avoid leakages. Commercial refrigeration systems are characterized by sig- nificant leakage (15–30% of annual charge).

If no reduction measures were taken, 2009-2015 emissions from ODS banks could exceed all reductions achieved in 4 years under the Kyoto Protocol (2008-2012).
