Border Carbon Adjustment Tariffs and Decarbonisation

Duncan Baker Excerpts

Wednesday 16th December 2020 Commons Chamber

[Jerome Mayhew]

I thank my hon. Friend for his intervention. The answer is that there are many different ways that we could approach it. The simplest would be to choose the five or six key carbon-heavy industries and start with them. As we get more knowledge of how to implement this kind of scheme, we could spread out to the wider economy. I suggest that the best way to do that would be to look at the carbon-emitting credentials of the energy market in the third country and assess in broad terms what its carbon contribution is. For example, in China, the coal contribution to the energy mix is between 70% and 80% and we would use that as the basis for the carbon contribution of its imports. When we get a bit more sophisticated, we could look at giving rebates to individual businesses that can demonstrate that they have a low-carbon approach despite the high-carbon attitude of their country as a whole. That would benefit behaviour and would not be protectionist, but would merely be a fair assessment of the carbon cost of transactions.

Moving on to energy, we naturally assume that we create all the energy that we use in this country domestically, but that is not the case. On average, we import, via undersea interconnectors, about 7% of the electricity that we use in this country. Members may recall that, last May, we trumpeted in the press that we had a two-week period in which we were coal free. We had coal-free electricity for two weeks. That was very exciting, but what the newspapers failed to mention was that, during that two-week period, we imported from Holland 40 GW of coal-fired electricity. The reason that we did that was not that we lacked generating capacity in the United Kingdom, but that it was cheaper to import coal-fired electricity from mainland Europe than it was to use our own. The reason why it was cheaper was that it was entirely tax-free, whereas we imposed a carbon tax on the generation of our own domestic electricity. Unbelievably, we actually incentivise the importation of high-carbon coal-generated electricity at the expense of our domestic manufacturing processes. How can that be right? A border carbon adjustment would sort that out in a jiffy.

What single better way is there to forward this Government’s levelling-up agenda than by putting in place the economic conditions for the market to want to re-industrialise in the UK, and all that with no need for Government subsidies. In fact, not only does it not require Government subsidies but it will actually produce an annual windfall for the Treasury year after year. Working out how big that windfall might be has a number of imponderables in it, but the Grantham Research Institute of Climate Change and the Environment has produced a report on this and, again, using the assessment of a carbon price between £50 and £75 a tonne, starting in 2020 and working up towards 2030, it assessed that the gross amount that the Treasury could recover under this process would max out at £36.7 billion a year. I stress that that is the gross amount. Members may well take the view that, rather like VAT, this is a tax that is consumer based and would impact poorer households disproportionately as a percentage of their gross income. The Government might very well want to use some of that £36.7 billion to cushion the blow and to make it more acceptable for lower-income families, perhaps by investing in insulation for their houses or other measures.

My hon. Friend is making a fascinating speech—despite starting off talking about sheep, he has managed to keep everyone’s enthusiastic attention throughout. A lot of emissions-intensive British industries will already find it difficult to compete in the global marketplace. As we begin to encourage the use of carbon capture and clean hydrogen by heavy industry, they will face higher production costs. Would a border carbon adjustment enable heavy industry to decarbonise while preventing job losses, and is that something the Treasury would also find attractive?

[Jerome Mayhew]

My hon. Friend has hit the nail on the head, because one of the key benefits of a border carbon adjustment is that it would allow us to decarbonise, and allow our heavy industry to accept the pain of higher energy costs, therefore letting the market work in our domestic market to incentivise the development of lower-carbon technology, while at the same time protecting it from being undercut by countries that are taking a little longer to go on the low-carbon journey.

We are not going to be spending money; we are going to be making money. That money could be used as the Treasury knows best. It does not mean that the money is taken out of the economy, because it could be put straight back in—in productivity-enhancing tax cuts, I hope, but that is up to the Treasury.

Best of all—I have saved the best till last—by freeing up the ability to price domestic carbon emissions at a realistic, behaviour-changing level, we can unleash the magic of the free market to seek out the most efficient solutions to low-carbon production. We do not need the Government to pick winners and subsidise industry once a market is working properly. Give a price to carbon, and that is exactly what we will create: a many-headed monster of innovation, entrepreneurialism, dynamism and efficient, productive capital growing our low-carbon future.

This future, if we are brave enough to embrace it before other nations, rather than just following, and if we are bold enough to allow the reshaping of the economy by demand rather than by direction, will equip our industry as leaders in low-carbon manufacturing. They will be leaders because they will be swimming in their natural element, whereas their international competitors will still be struggling to react to the short-term Government green initiatives and schemes that we all currently suffer from. It is a lead that could generate exports and growth in this country.

What is stopping us from delivering on the Prime Minister’s vision of a low-carbon, dynamic economy? Some worry about a protectionism challenge at the World Trade Organisation, but with a BCA applied in an open and transparent manner, nothing could be further from the truth. This policy is about removing unfair competition, not creating it. In any event, WTO rules expressly allow for tariffs whose purpose is to protect

“human, animal or plant life and health”

or

“to conserve exhaustible natural resources”.

Those are two exceptions tailor-made for this kind of tariff.

More practically, if the UK were to join the United States of America, our friends in the European Union and other countries to establish the principle of BCAs at COP26, that would be a game changer, because that would ensure their practical acceptance. Others worry that putting forward such an ambitious proposal at COP26 runs the risk of failing to achieve the consensus that would allow the PR men to claim a stunning success. It might, but the risk of failure is the price of ambition, so should we give up on our ambition? Of course not.
