17:23 Christopher Chope (Conservative)

I will concentrate on the issue of the population, because that is the core issue we have got to address. In 1990, which is the base date for all our policies relating to net zero and so-called climate change, the population then was about 20% less than it is now. There has been a 20% increase in population since then, yet all our net zero targets are related to absolute figures, rather than to carbon dioxide emissions per head of population. That is a dimension to the debate that I do not think we have sufficiently addressed.

When the Environmental Audit Committee, on which I have the privilege of serving, was asking an environment Minister the other day what is being taken into account in determining the impact of rising population on the ability of the Government to deliver on their net zero targets, there was a big gasp—“Oh, well, there is no briefing on that.” He did not have a clue. All that happened was that the Minister resorted to talking about heat pumps. He seemed to think that that was the answer to the question, which I raised. Yet we know that heat pumps are a subsidiary issue.
