§ Mr. Peter Ainsworth
To ask the Chancellor of the Exchequer what recent estimate he has made of reductions in emissions of(a) carbon dioxide, (b) methane, (c) nitrous oxide, (d) hydrofluorocarbons, (e) perfluorocarbons and (f) sulphur hexafluoride which are attributable to the climate change levy. 
§ Mr. Boateng
The most recent estimate of the carbon emission savings attributable to the Climate Change Levy is published in EFSR 2002 (Table 7.2, page 142). These emission savings related solely to carbon dioxide. No estimate has been made of reductions in the other five greenhouse gases.
