Mike Penning: To ask the Chancellor of the Exchequer what assessment he has made of the impact of the Climate Change Levy; and if he will make a statement. [20429]
John Healey: The Government published an independent evaluation of the Climate Change levy (CCL), "Modelling the Initial Effects of the Climate Change Levy", by Cambridge Econometrics at Budget 2005, which is available at:
www.hmrc.gov.uk
The evaluation concluded that CCL is expected to deliver carbon dioxide savings of over 3.5 million tonnes of carbon by 2010, well above the estimates made at the time of the levy's introduction. |
