Summary
Hydrofluorocarbons (HFCs) are greenhouse gases with high global warming potentials that are mainly used in refrigeration and air conditioning. Historically, they were emitted only slowly from such systems and long term containment remains an important engineering and environmental issue. As part of their commitment under the Rio convention, nations are required to report annual calculated production and emissions of all greenhouse gases and the reports submitted by the European countries have been examined to determine the extent to which containment of HFCs (expressed as the rate of emission from the bank remaining in equipment) has changed with time. Although there is wide variation between countries, the annual emission rates of [...]
Summary
Hydrofluorocarbons (HFCs) are greenhouse gases with high global warming potentials that are mainly used in refrigeration and air conditioning. Historically, they were emitted only slowly from such systems and long term containment remains an important engineering and environmental issue. As part of their commitment under the Rio convention, nations are required to report annual calculated production and emissions of all greenhouse gases and the reports submitted by the European countries have been examined to determine the extent to which containment of HFCs (expressed as the rate of emission from the bank remaining in equipment) has changed with time. Although there is wide variation between countries, the annual emission rates of HFCs have improved significantly over the past 10 years and now represent between 5 and 10% of the bank still contained in equipment. This implies that, at the present state of technology, it would take at least 10–20 years for the original mass of refrigerant charged into a system to be released into the atmosphere.
