I have been asked to reply.
Total UK greenhouse gas emissions were estimated to be 664.1 million tonnes of carbon dioxide equivalent in 2000. HFC134a and HFC407c contributed respectively 2.61 million tonnes and 0.35 million tonnes to these emissions. Together, they represented about 0.5 per cent. of the total.
