Reported on Guardian Unlimited today:

Housebuilders are trying to persuade the government to ditch a key policy designed to cut carbon emissions through constructing green homes.

Britain’s renewables industry and many local authorities are concerned that intense lobbying may have persuaded the government to rethink.

It is assumed the housebuilders in question do not include those commiteed to the 2016 Commitment to zero carbon housing (see Communities and Local Government website)
