Carbon Emissions

Volume 459: debated on Thursday 3 May 2007

To ask the Secretary of State for Environment, Food and Rural Affairs what estimate he has made of the reduction required in UK carbon dioxide emissions by 2050 if the UK is to meet its share in an international goal of stabilising greenhouse gases in the atmosphere at between 450 and 550 ppm of carbon dioxide equivalent. (131737)

There is no simple relationship between a long-term stabilisation goal and the pathways required to get there. The most recent science indicates that to stabilise at between 450 and 550 ppm CO2 equivalent, global greenhouse gas emissions would need to fall by between 10 per cent. and 65 per cent. below 1990 levels by 2050.

The UK’s target of a 60 per cent. reduction in carbon dioxide emissions is consistent with this approach. However, we recognise that we will need to keep this goal under review in the light of emerging scientific evidence and other developments.
