Net-zero Emissions

Lord Mackenzie of Framwellgate Excerpts

Tuesday 7th December 2021 Lords Chamber

[The Parliamentary Under-Secretary of State, Department for Business, Energy and Industrial Strategy (Lord Callanan) (Con)]

My Lords, to meet net zero, virtually all heat in buildings will need to be decarbonised. The net-zero strategy outlines that we expect that emissions could fall by between 25% and 37% by 2030 and 47% to 62% by 2035 compared with 2019 levels, based on an indicative heat and buildings pathway. The heat and buildings strategy shows our robust plans to do so.

[Lord Mackenzie of Framwellgate (Non-Afl)]

My Lords—

[Noble Lords]

Order!

[Lord Callanan (Con)]

The noble Lord makes a very good point. We need to look at embodied carbon much more closely. Indeed, I attended and launched a session on exactly that at the COP climate change talks. We will work with industry practitioners to see what more we can do in this important area.

[Lord Mackenzie of Framwellgate (Non-Afl)]

My Lords, I apologise for my premature intervention. Are all domestic new builds taking place since the Glasgow COP meeting last month being built to the new specifications required by the Heat and Buildings Strategy? If not, why not?

[Lord Callanan (Con)]

The new building regulations for net-zero homes will take effect from 2025, but of course we are not waiting that long to take action. The new Part Z of the building regulations will kick in from next year.
