Net-zero Carbon Emissions: Behaviour Change

Lord Bishop of Blackburn Excerpts

Thursday 16th September 2021 Lords Chamber

[The Lord Bishop of Blackburn]

My Lords, I too am grateful to the noble Baroness, Lady Blackstone, for the opportunity of this debate. I have just finished reading a book about wilding in the UK, and it is a classic story of how difficult it is to change a culture, attitudes and expectations from deeply embedded practices and convictions, in this case about how we manage our land—which was appropriate, with the Environment Bill this week. The same difficulty applies in this debate, which is less about government policy and more about how we, as citizens, choose to live.

My main point, in discussing the role behaviour change can play in helping us towards net-zero carbon emissions, is this: it is essential that our expectations are aspirational, but also realistic. They need to apply to all people. It is my fear that the poorest 10% will be left not just behind, but feeling that they are part of the problem, when they would rather be part of the solution.

So far, the behaviour changes we wish to see have been inaccessible to many on low incomes, simply because they cost much more. I believe cars that are powered without petrol or diesel are the future, and I hope to see a mix of financial incentives and legislation to encourage their uptake and so change our choices, but they remain considerably more expensive in outlay and then do not hold their value. A petrol car is cheaper and easier to sell on and, if I live in accommodation without a driveway, is considerably easier to fill with the required fuel. So it is for other goods, such as locally grown organic food, which remains more expensive than highly processed food grown out of season abroad. Similarly, I have complete sympathy with any working single parent who decides to shop for the cheapest school shirts money can buy, instead of those made of fair-trade cotton. Food, clothing, travel—all these remain prohibitively expensive for some. When we seek to change the behaviour of the whole population, we must consider how we might incentivise with price reductions or even subsidise these things to make them accessible to all.

Also, the industries that employ people on lower incomes must be those we seek to incentivise, and possibly most strongly penalise when they fail to make the necessary changes. Manufacturing, food production, aspects of the gig economy: these are all sectors that will have to put their greenhouses in order or presumably risk facing sanctions designed to force a change in behaviour. Wages could be pushed down and jobs could even be lost to pay for the necessary changes in production and carbon offsetting, and the burden will be borne by those at the bottom of the pay scale.

Finally, it feels that every time I am here I bring up the same matter. I follow the focus of the noble Baroness, Lady Randerson, which is that public transport in the north of the country remains inadequate, particularly between the big cities and most especially for those on low incomes who need it most. It is essential for the change of behaviour we seek, and for the sake of the climate, that funding per head on transport infra- structure is, to use Her Majesty’s Government’s phrase, levelled up.

One should not be surprised to find out that spending on transport infrastructure is higher in London than in any other part of the country, but that spending per head is so considerably higher in the capital than in the north of the country is less easy to comprehend. Indeed, I recently read that it is twice as much per head than in the north-west and more than three times as much as in Yorkshire and the Humber. How can people be expected to change their behaviour and choices if the opportunity is not given them to do so? Without proper and fair investment in greener ways to travel, reliance on road travel will only increase, especially after the pandemic, which still impacts the numbers who use our trains, trams and buses.

In summary, the blend of incentives and penalties I have heard suggested will be essential in helping us all change our behaviour, which is incredibly important and very possible as we seek to reach net-zero carbon emissions. However, we must do it in a way and a manner that does not leave any constituency behind. Lack of financial means should not prevent some sharing the journey to net zero. I mentioned the book I read just recently, in which the quote is given: you can’t be green if you’re in the red.
