Lord Lilley: My Lords, does my noble friend agree that living standards generally can rise only if we produce more output per head? Conversely, living standards will fall if we need more workers to produce our existing level of output of energy or heating. Yet this strategy says that upgrading our homes and buildings to warm them without using fossil fuels will require 240,000 more workers than at present, who will no longer be able to produce other goods and services. Does my noble friend think that reducing the average living standards of the country is what people voted for?
Lord Callanan: I am sure people did not vote to have their living standards reduced. Indeed, we have an excellent record of both decarbonising and growing the GDP per head of population. We have a very successful record of doing that so far, and I hope we will continue to be able to do so. I remind my noble friend that whatever our individual views on this, we now have a legal obligation to meet net zero.
