CFCs, HCFCs and HFCs are significant Global Warming Gases and all nations have an obligation to reduce Global Warming Emissions (expressed as tonnes of CO2).
The Kyoto treaty created legislation to reduce emissions of these gases to 5.2% below the 1990 levels. This sets out goals for reducing greenhouse gas emissions, thought to be responsible for global warming. This became a global treaty when Russia adopted it in 2005.
F-Gas Regulation (2006)
These regulations were the European response to the Kyoto Protocol and outlined a number of areas that would improve emissions. The regulations set controls for record keeping, inspection for leakage and competence levels for engineers. These were published in the Official Journal and took effect on 4th July 2006 with controls being introduced from July 4th 2007 and 2008.
