Paul King, speaking today at the event ‘Beyond Merton: local planning for cutting carbon’, said the Government should look to cut carbon emissions by 30 per cent on new developments.
The Merton rule is a pioneering local policy from the south London borough, which requires all new developments to reduce 10 per cent of its carbon emissions.
It is now used by more than 80 councils and has been used as a benchmark for the industry.
But Mr King said: “I believe we should be looking to reduce by 20 to 30 per cent on new developments.
“The industry should not shy away from hard targets.”
And Mr King revealed that housing minister Yvette Cooper had written to him to assure that the policy will not be scrapped as an industry measure when the Climate Change Planning Policy statement is released later this year.
