The aim of this work is to make a preliminary assessment of the options and costs of controlling three gases--HFCs, PFCs and SF6--as well as the barriers for implementing reduction policies for these gases. This report provides a first estimate of the development of the European-Union-wide use and emissions of HFCs, PFCs and SF6 in 2005 and 2010 (compared to 1990/1995) with existing (current) national and community policies, which presents existing estimates of the (capital and operating) costs and associated emission reductions (in 2010) of options to control HFC, PFC and SF6 emissions in the EU 15 and identifies and elaborates on the barriers for implementing the identified emission-reduction options.
