Net-zero Carbon Emissions: Behaviour Change

Lord Browne of Ladyton Excerpts

Thursday 16th September 2021 Lords Chamber

[Lord Browne of Ladyton (Lab)]

My Lords, it is a genuine pleasure to follow the right reverend Prelate. I commend him for reminding us how important it is to consider first those at the bottom of the pay scale; I thank him for that.

I congratulate my noble friend Lady Blackstone and thank her for instituting and introducing this important debate on the role of behaviour change and the case for a public engagement strategy in helping us to reach net-zero carbon emissions by 2050. She made an excellent and comprehensive speech, which has already been commended. I hope the Minister will respond positively to it, as she asked him to do.

I thank all the organisations that have circulated briefing papers to speakers and more broadly. They are all of value and, like the excellent Library and Peers for the Planet briefings, have increased my knowledge and contributed to our debate even before a word had been spoken in the Chamber. On that point, let me take just a few seconds to repeat a suggestion that I have made twice before in the context of debates in your Lordship’s House.

I cannot do justice to any of the briefings—I have no intention of going through the many proposals they suggest; we can all read them for ourselves—but they contain many good points and, as the focus of this debate is on public engagement, I ask again: can we not open a web-based portal for every debate, or at least some, which would allow people who wish to engage with us to post their briefings in real time and have them preserved with the official record of the debate, and would expand the debate out into society? It would create a much more inclusive context for our work and allow us a significant amount of outreach too, given that we are constantly seeking ways to make our deliberations more relevant to a wider audience.

According to the CCC report, three-fifths of the measures required to get to net-zero emissions will require at least some degree of behavioural and social change. However, as Lorraine Whitmarsh, professor of environmental psychology at the University of Bath, commented:

“But this only factors in changes in consumer behaviour, such as switching from petrol to electric cars, or gas boilers to heat pumps.”


The list is endless; it has already been covered substantially in contributions. She continued:

“This is a very narrow definition of behavioural and social change. People are not only consumers—they are citizens, parents, members of communities, employees, employers and political actors.”


I add to that that people are company directors, politicians and Ministers. One view is that the truth may be that all the measures required to get to net zero depend on behavioural change by people.

As I have already said, I cannot do justice to any or all of the briefings I received, but for the rest of what I am going to say I will concentrate on the issue of trust, because that is about our behaviour—not just that of Ministers but of parliamentarians. I was struck by the last bullet point in the Climate Outreach briefing I received, which says:

“The public takes strong cues from government action so policies and government spokespeople”—


I would add parliamentarians—

“need to be seen as being in tune with the action being asked of individuals.”

The heading that it gives is that the Government needs to be in step.

Regrettably, at a micro level the Government, and probably many of us, have recently had problems in this area. The sight of a Cabinet—at which there were at least 27 senior members of the Government sitting close together around a table without face masks—agreeing that a key message to deliver to the people is to wear a mask in crowded settings was not helpful, nor is the regular drumbeat we have of Ministers and others being embarrassed by being asked simple questions such as, “What sort of car do you drive?” This is really important, and all of it is very good fun at this level, but at the macro level there is an important issue. If people are to be persuaded to change their personal behaviours, Governments, leaders and we must inspire confidence that we are tackling the larger and more difficult challenges—and we are comprehensively failing to do that. We regularly say that the Government’s primary responsibility is their duty to protect citizens. We have to be really careful that asking individual citizens to bear the burden of a substantial share of global warming does not reverse that relationship, moving responsibility from the protectors to those who should be protected. Part of the public engagement strategy must be empowering citizens to hold their Governments to account for their responsibilities, first and foremost.

A relatively recent report from the Carbon Disclosure Project—now known as the CDP—found that just 100 companies were responsible for 71% of global emissions since 1988 and that a mere 25 corporations and state-owned entities were responsible for more than half of global emissions. Mostly these are fossil fuel companies, and China is responsible for a disproportionately large share of global greenhouse gas emissions due to its coal production and consumption. A few countries and companies are responsible for so much of global greenhouse gas emissions that our first response should be, at business and government level, to ensure that people take responsibility for curbing industrial emissions. That should be our priority.

This is not to say that individuals cannot do things. They can, of course: we have heard about them and there are lists of them. Every contribution helps, but we must be careful not to get to the point where these failings are considered morally blameworthy. In particular, individuals living in poor countries who have contributed almost nothing to climate change deserve the most support and the least guilt.

I repeat that the most effective change in behaviour will be to empower citizens to hold those who are responsible for climate change accountable for their actions. That is why a successful COP 26 is so crucial. Unfortunately, I am not very confident that it will deliver.
