Establishing the Leakage Rates of Mobile Air Conditioners

Description: The purpose of the study is to - based on field measurements - determine the average annual leakage rate of HFC-134a from MACs in the European Union of a "second generation"1 air conditioner. From November 2002, to January 2003 300 measurements of HFC-134a leakage were carried out on air conditioners of cars up to seven years age.

While CO2 emissions associated with human activities continue to rise -- and may be worthy of alarm because of their influence on climate change -- any short-term comparisons between actual emissions and the Intergovernmental Panel on Climate Change (IPCC) scenarios miss the mark. This report analyzes this issue and the issues associated with IPCC scenarios an… more
