Climate Change Act 2008 (2020 Target, Credit Limit and Definitions) Order 2009

My Lords, I am most grateful to my noble friend for his clarification and assurance on tracking the income distribution or social equity consequences. However, it is widely understood that, in supporting the noble Lord, Lord Stern, the Government agree that the economy will continue to grow but at a slightly lower rate—in the order of 1 per cent slower—than if there had been no other constraint, including climate change. Will my noble friend note that that is a separate but important consideration? We are seeing how a 1 per cent change in GDP affects employment. An undertaking needs to be given that that, too, will be subject to further analysis and tracking. Although it sounds like a small figure, it is not inconsiderable if we all agree that the general rate of economic growth in terms of productive potential is adrift by 1 per cent.
