New measures to make buildings more energy efficient will save one million tonnes of carbon per year by 2010, the government has claimed.
This is equivalent to emissions from more than one million semi-detached houses.
These claims came as the government yesterday revealed its draft proposals for the long-awaited revisions to Part F and Part L.
The new documents - which come in to force in April next year - will force new homes to be better insulated and make use of more efficient heating systems.
Among these changes, the revised Part L will, for example, make air pressure-leakage testing of buildings mandatory, improving compliance with the regulations by showing where there is unacceptable leakage, which can reduce the energy efficiency of buildings.
Housing and Planning Minister Yvette Cooper said the government was determined to raise standards in housebuilding consistently.
'We are driving up standards for new homes so that housing can do its bit to combat climate change,' she said yesterday. 'These new standards are good news for consumers' energy bills and for the environment too.
'This is the latest in a line of improvements ranging from refurbishing social housing to tightening boiler regulations, which are helping to cut carbon emissions.
'It shows that we can build new homes for the next generation, whilst improving protection for the environment as well,' she added.by Ed Dorrell
