HFCs and the control policy for H(C)FCs and its relation with Dutch policy regarding the emission of greenhouse gases. Scenarios for global and Dutch use of hydrofluorocarbons and their consequences for global warming

HFK's en het (H)CFK-reductiebeleid in relatie tot het beleid inzake Nederlandse emissies van broeikasgassen. Scenario's voor mondiaal en Nederlands gebruik van gehydrogeneerde fluorkoolwaterstoffen en hun relatie met het broeikas-effect

Synopsis

Hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs) are important substitutes for chlorofluorocarbons (CFCs) and halons. HCFCs have a lower Ozone Depleting Potential (ODP) than CFCs and halons, and are therefore considered temporary substitutes, while HFCs have zero ODP. In addition to ODP many halocarbons also have a Global Warming Potential (GWP). We developed in this report three different scenarios, globally as well as for the Netherlands: (1) the 'London' scenarios, in which HCFCs and HFCs are used unrestrictedly to replace CFCs and halons ; (2) the 'Copenhagen' scenarios, which consider an additional phase-out of HCFCs, after which the use of HFCs increases ; and (3) the 'Additional Policy' scenario, which assumes the use of compounds, with zero ODP and a relatively small GWP. In this report we describe the potential use of HFCs worldwide and in the Netherlands in 2000/2010 and its contribution to greenhouse gas emissions. Particular attention is given to alternative agents, so-called 0-ODP and low or 0-GWP compounds. In addition the GWP values of HFCs and their uncertainty are discussed. Furthermore, sources of emissions and reduction options by using alternative agents and methods are described. Finally conclusions are presented with respect to options for additional climate policy regarding HCFCs and HFCs. Additional measures will reduce CO2-eq. halocarbon consumption substantially. Without additional policy for HFCs, the share of halocarbons in total CO2 equivalent emissions in the Netherlands will increase from 3 to 7%-11% in 2010 (assuming a zero GWP for CFCs and halons), while substitution by low or zero GWP alternatives leads to stabilization at the 1990 level. Presently the limitations for additional policy are the limited knowledge of the options with regard to technical-economical feasibility, safety aspects, of costs of policy measures and regarding direct and indirect GWPs of HFC compounds and alternative agents. Also, a better insight in the potential for increasing recycling rates is important. A summary of this report has been published in English as paper.
