Chris Huhne commits to halving the UK's carbon emissions
Chris Huhne has committed the UK to halving carbon emissions by 2025, from 1990 levels, and changing the way that the country produces energy.
Mr Huhne told MPs the budget would "set Britain on the path to green growth".
"It will establish our competitive advantage in the most rapidly growing sectors of the world economy," he said.
The Climate Change Act 2008 sets a target to reduce greenhouse gas emissions in the UK by at least 80% on 1990 levels by 2050, and also requires the government to set carbon budgets – limits on emissions – for consecutive five-year periods.
Mr Huhne said he agreed with the committee that net emissions over this period should not exceed 1,950 million tonnes of carbon dioxide equivalent – a 50% reduction from 1990 levels.
"We will aim to reduce emissions domestically as far as is practicable and affordable," he said.
