My Lords, the Government’s attempt to solve the current housing crisis needs, at the same time, to address the issue of what types of homes are built. They should be of high quality and high energy efficiency standards which drive down future energy bills, help to protect against fuel poverty and provide healthy living environments. The Explanatory Notes to the Bill make it clear that its principal aim is to bring forward proposals that make homes more affordable. This laudable aim was dealt a serious blow by the scrapping of the zero-carbon homes policy by the Chancellor last July. Without this standard, which until last July had cross-party and cross-industry support, the new homes promised by the Government will not be as affordable as they might be. They will lock their owners into a cycle of higher fuel bills and the need for costly retrofits. The amendment requires that all new homes built in England from 1 January 2018 achieve the previously agreed zero-carbon homes standard.
Reinstating this housing standard will not only help keep homes affordable for the long term, it will help meet our legally binding climate commitments. We are committed to reducing UK emissions by 50% by 2025. Buildings accounted for 34% of the UK’s total greenhouse gas emissions in 2014, with 64% of building emissions coming from homes. It is in the building sector that most of the cost-effective potential carbon savings are to be found. Housebuilding must, of course, remain financially viable for the private sector, which will deliver the bulk of future housing. Yet the scrapping of zero-carbon homes by the Chancellor was not accompanied by any evidence that building homes to that standard would affect the speed at which the UK can build new homes. Indeed, evidence to the House of Lords Select Committee on National Policy for the Built Environment showed that the removal of the zero-carbon homes requirement has generated uncertainty for homebuilders. Moreover, they were provided with no clear evidence that the removal would lead to an increase in housebuilding. This evidence persuaded the committee—and I declare an interest as a member—to
call on the Government to reverse the decision to remove the requirement for new homes to generate no net carbon emissions.
Reinstating the zero-carbon standard would help deliver affordable homes for the long term, and not burden occupants with needlessly high energy bills. This would also make the UK’s statutory greenhouse gas emission targets more achievable. Post-Paris, it is surely time for leadership and not backsliding. I beg to move.
