Finance Bill (Fourth sitting)

Harriet Cross Excerpts

Committee stage
Thursday 30th January 2025 Public Bill Committees

[Emma Reynolds]

The clause will enable the commissioners for HMRC to prepare for the introduction of the UK carbon border adjustment mechanism and allow information to be disclosed for the purposes of developing the CBAM.

The Government are committed to reaching net zero by 2050. As we make progress to decarbonise, we must ensure that the effect of our efforts is not undermined by carbon leakage. I am sure that hon. Members know this, but for the benefit of the Committee, let me define carbon leakage: it is the movement of production and its associated emissions from one country to another to avoid higher decarbonisation efforts and costs. The best solution to carbon leakage risk would be international co-ordination on decarbonisation and carbon pricing. However, many countries do not yet have domestic carbon pricing mechanisms. Consequently, introducing the UK CBAM will reduce the risk of carbon leakage by placing a carbon price on carbon-intensive goods imported into the UK from 2027.

The new tax will enable a charge to be placed on the carbon emissions found in highly traded carbon-intensive goods imported into the UK from the aluminium, cement, fertiliser, hydrogen, iron and steel sectors. A comparable carbon price will be placed on those goods, based on what they would have incurred if they had been produced in the UK under our domestic emissions trading scheme.

[Harriet Cross (Gordon and Buchan) (Con)]

I understand the principle of CBAM. However, in practice, if we import fertiliser to increase our food production here, for example, we will reduce our imports of food from elsewhere. It might not balance out exactly, but we would not be changing how much carbon we sent abroad, because we would just be taking it from another mechanism that is not included in the CBAM.

[Emma Reynolds]

I thank the hon. Lady for her intervention, but I am not entirely sure that I follow the logic. The purpose of CBAM, as I have said, is to ensure that if a product is produced using carbon in another country, we do not have leakage across the border. The overall impact will vary depending on the sector’s exposure to CBAM imports relative to the overall input costs and the extent to which it can substitute them. CBAM imports make up only a small proportion—about 1%—of average UK industry input costs. CBAM liabilities are expected to be small initially, and reliance on inputs of goods within scope across the economy is limited overall. I am not sure that I follow the logic that imposing CBAM on imported fertilisers will somehow have the effect that the hon. Lady suggests.

The UK emissions trading scheme is the UK’s primary carbon pricing mechanism. The scheme was established to increase the climate ambition of the UK’s carbon pricing policy while protecting the competitiveness of UK businesses. The UK CBAM will be implemented only in sectors where it will effectively mitigate carbon leakage risk and where delivery is deemed feasible. Other sectors that give rise to carbon leakage will be considered for future inclusion.
