Net-zero Emissions: Behaviour Change

Lord Frost Excerpts

Thursday 20th October 2022 Lords Chamber

[Lord Frost (Con)]

My Lords, I thank the right reverend Prelate, the Government and the Minister for proposing and enabling this debate today. It is an extremely important subject. I also thank the noble Baroness, Lady Parminter, for her committee’s report on this subject, as has been mentioned.

We all agree, I think, that decarbonisation is a very desirable goal, but that aspiration is different from the specific net-zero 2050 policy. That target was essentially invented by the Climate Change Committee in 2019, passed through secondary legislation in this Parliament with limited debate and, since then, has been creating radical change to the economic structure of this country. My own party is just as much to blame for this situation—possibly even more so—as the parties of noble Lords opposite.

To be fair to the Climate Change Committee, it correctly stated in 2019 that there would need to be policy change to deliver this goal. It specifically mentioned decarbonisation of industry, the grid, insulation, renewables, boilers, carbon capture and storage, and so on. Now, however, we find, first, that all these technical measures are extremely expensive to install; secondly, they make energy and normal life very expensive for people; and, thirdly, they are increasing the unreliability of the energy sector, worsened by the destruction of energy supply that is actually reliable and by the addition of too many renewables that destabilise the grid.

We see a situation where the technology does not deliver the goal or aspiration by 2050 and behavioural change is beginning to fill that gap, which I find somewhat troubling. I will make three remarks. First, “behavioural change” is a nice phrase, but let us look at what it actually means: it means making it harder for people to do things that they would otherwise choose to do. One of the Government’s slogans is:

“Make the green choice affordable”.


Another way of putting that is: subsidise substandard and ineffective technologies, chosen politically by government, which people would not choose to use otherwise. Behavioural change, then, reduces human welfare, making people do things that they do not want to do, rather than things they do.

Secondly, if we take the phrase at face value, behavioural change should be voluntary. It means encouraging or nudging, but it often feels as though that is not what is being described. In 2021, the Climate Change Committee said:

“Behaviour change … comes through consumer adoption of low-carbon technologies such as electric cars”.


You do not get any choice about that: from 2030, you have to buy an electric car. That is not nudging but compulsion. The same is true for heat pumps from 2025 and closing roads for cyclists—it is all compulsion.

The same is true of the aspiration to learn from the pandemic set out in the committee’s report, from which I note my noble friend Lord Lilley wisely dissented. Yes, behavioural change was encouraged during the pandemic, but the key aims were achieved by legal compulsion: making it illegal to leave your home and meet people, and fining you if you did so. That is not nudging but simple compulsion, and if people mean legal compulsion, they should say it.

Finally, we are already in a society where far too much is governed by politics, which is too much in every sphere of everyday life. I worry that behavioural change and climate measures are shrinking the private space of individuals. They turn every decision—every time you go to the supermarket or travel—into a political act, which is a bad thing for society. Free societies should have large spaces where there is free choice.

I conclude by urging the Government on this. They have done quite enough encouragement of behavioural change as it is; there is no need for more. The right way to the decarbonisation goal is on the supply side. Provide the energy that people need but do not tell them not to use it. The right way forward is from natural gas to nuclear, with renewables at the margin, and investment in new technology—batteries and hydrogen—so that we have the low-carbon power that a modern industrial society needs. That is the way forward.
