Ministers must resist pressure to relax environmental standards in the rush for new housing

Almost two decades after the last Labour government announced a zero carbon homes standard, and with the breaking of temperature records around the world now so normal as to seem routine, it ought to be uncontroversial that new buildings should be as environmentally friendly as possible. Given everything we know about global heating, and the law obliging the UK to reach net zero by 2050, it is disturbing that even the basics of promotingenergysecurity and efficiency continue tobe questioned.

But that is the situation Britain faces, as the government lays the ground for a housebuilding spree that it hopes will last for the rest of this parliament (as planning is devolved, the target of 1.5m new homes is for England only). Much of the blame for this discouraging state of affairs lies with the Tories, who delayed progress towards sustainability by scrapping environmental rules, leading to a disgraceful proliferation of new developments where the houses do not even have solarpanels on the roofs.
