Committee on Climate Change says it sees 鈥渘o rationale鈥 for letting small developments off the standard
The government鈥檚 own climate watchdog has slammed the plan to exempt small housing developments from the zero carbon homes standard when it is introduced in 2016 and urged it to scrap the proposal.
The government has a long standing commitment to introduce regulations to ensure that all homes built from 2016 are zero carbon.
However, in June the government announced that small developments would not be subjected to the standard.
Today, in its annual report on the government鈥檚 green policy progress, the Committee on Climate Change said there had been 鈥渘o rationale鈥 provided for the policy change.
It said: 鈥淚t is not clear why the economics of efficiency measures or low-carbon heating should significantly differ from larger developments. Therefore, this proposal should be dropped unless the government can show clear evidence of its value.
鈥淢ore generally, the scope of the zero carbon homes policy has been changed a number of times in recent years. While policy changes can be justified in some circumstances, too frequent change creates uncertainty and can result in badly designed policies, and should therefore be avoided in future.鈥
It also said that progress on increasing the energy efficiency of the UK鈥檚 existing buildings stalled last year.
The committee said that there had been a 鈥渟ignificant reduction鈥 in the roll out of loft and cavity wall insulation.
It concluded that 鈥渋nsufficient鈥 incentives for the 鈥渃omplex鈥 Green Deal scheme had caused the fall in installations and halted the 鈥済ood progress鈥 made in 2012.
The committee also said the Green Deal鈥檚 sister scheme, the Energy Companies Obligation, should have its targets for the period to 2017 increased to help make up the shortfall.
It added that the Green Deal Home Improvement Fund, which was launched in June 2014 to pay cash incentives to people taking up energy efficiency measures in their homes, should be extended to 2017.
Lord Deben, chair of the Committee on Climate Change, said: 鈥淭he UK is still not on track to meet our statutory commitment to cut emissions by 80%. The longer we leave it, the costlier it becomes.鈥
Paul King, chief executive of the UK Green 好色先生TV Council, said there had been an 鈥渦nravelling of the previous good work on home energy efficiency鈥.
He said: 鈥淭his is ironic given that carbon reduction in buildings is not only the most cost effective way of tacking climate change, but it also protects both households and businesses from soaring energy bills.
鈥淭ime is running out for the current government to grasp this and to deliver on crucial policy areas such as zero carbon homes and minimum energy performance standards in commercial buildings.鈥
A spokesperson for the Department of Energy and Climate Change, said: 鈥淲e are not complacent and realise there鈥檚 more work to done as we keep up the momentum towards a low carbon economy while also ensuring we minimise the impact on consumers鈥 bills.鈥
