Contribution
My Lords, this order was laid before Parliament on 16 December 2025.
The UK Emissions Trading Scheme, or UK ETS, was established—perhaps I should say “re-established”—under the Climate Change Act 2008 by the Greenhouse Gas Emissions Trading Scheme Order 2020 as a UK-wide greenhouse gas emissions trading scheme, contributing to the UK’s emissions reduction targets and net-zero goal. The scheme is run by the UK ETS Authority, which is a joint body comprising the UK Government and the devolved Governments acting as one. Our aim is to be predictable and responsible guardians of the scheme and its markets.
Under the UK ETS, operators are required to monitor, report on and surrender allowances in respect of their greenhouse gas emissions. Although most allowances are purchased at regularly held auctions, operators in certain sectors at risk of carbon leakage are given a number of allowances for free; there are referred to as “free allocations”. Free allocations reduce the exposure to the carbon price for sectors at risk of carbon leakage and reduce the risk that decarbonisation efforts could be undermined by production and the associated emissions moving to other countries.
Under the UK ETS, an operator is the person or company with control over an installation. Installations are stationary units at which regulated activities take place. Sub-installations represent operations carried out at an installation for which operators that receive free allocation are required to report activity levels for the purposes of the UK ETS.
We have brought forward this statutory instrument to enable important changes and improvements to the scheme. The first change it makes is to enable operators of installations to be able to notify their regulator that they wish their activity data for the 2020 scheme year, or 2020 and 2021 scheme years, to be excluded from the calculation of their historical activity levels for the 2027-30 free allocation period. This is in recognition of the fact that production levels may have been impacted during the Covid-19 pandemic. These operators will be able to notify their regulator during the second stage of the 2027-30 free allocation application, from 1 April 2026 to 30 June 2026, that they wish to exclude their activity data for 2020, or 2020 and 2021.
A legal change to the free allocation regulation is needed because existing legislation would require regulators to calculate historical activity levels using activity data from all five years of the baseline period from 2019 to 2023. So, if amendments are not made, there will be no legal basis for regulators to exclude data from 2020, or 2020 and 2021, from the historical activity level calculation for any applicant. Using activity data for these years could result in historical activity levels that do not reflect normal activity, meaning that operators would receive less free allocation than they would otherwise be entitled to receive.
The second change the instrument makes is to gradually phase out free allocation for sectors covered by the UK carbon border adjustment mechanism—the UK CBAM—starting over the 2027-30 allocation period. This phase-out will be implemented through applying a UK CBAM reduction factor to the calculation of free allocation, and will apply at sub-installation level. To do this, operators will be required to report on which of their sub-installations serve the production of UK CBAM goods. This will enable regulators to apply the UK CBAM reduction factor to the relevant sub-installations.
A legal change is needed as operators currently classify their sub-installations only by a specific benchmark and the corresponding carbon leakage status of that sub-installation. This instrument requires operators also to classify each sub-installation as “UK CBAM” or “not UK CBAM”. Benchmarks are the efficiency standards used to calculate each installation’s free allocation entitlement. Installations closer to their benchmark have a higher proportion of emissions covered by free allocation, rewarding more efficient installations and incentivising decarbonisation.
The third change the instrument makes is to use current benchmarks for the purpose of calculating free allocation for stationary installations for the 2027 scheme year. This instrument also provides for the ability to update the benchmark values used to calculate free allocation for the years 2028, 2029 and 2030 of the 2027-30 allocation period. Maintaining current benchmarks for the 2027 scheme year will allow time for industrial participants to adjust to the changes.
A legal change to the free allocation regulation is necessary because, under existing legislation, there is no provision to update benchmarks during an allocation period. The principal intent is to use the updated ETS phase 4 benchmarks in the 2028, 2029 and 2030 scheme years; this will be decided once the EU benchmark values are available and will be subject to assessment of the impact.
Installations that permanently cease to operate are required to report on their activity in the final year of operation so that free allocation can be recalculated to reflect the cessation of activity. This amendment clarifies that operators must report on their activity levels in instances of permanent cessation or the surrender or revocation of their permit.
These intended changes follow comprehensive engagement and consultation with stakeholders. The UK and devolved Governments carried out consultations that covered the provisions included in this statutory instrument. The free allocation review consultation ran between 18 December 2023 and 11 March 2024, seeking views on proposals to alter the free allocation methodology for UK ETS stationary sectors to better target those most at risk of carbon leakage and ensure that free allocations are fairly distributed. The free allocation review carbon leakage consultation ran between 16 December 2024 and 10 March 2025. It sought views on a draft UK-focused carbon leakage list compiled by applying UK data to the existing carbon leakage list, as well as the trajectory for phasing out free allocations for sectors that will be covered by the UK carbon border adjustment mechanism. The relevant responses to these consultations were summarised in the UK ETS authority’s response.
In conclusion, the changes in the draft order will deliver on commitments made by the UK ETS authority, improve the fairness of the scheme and increase certainty for both regulators and operators. These changes will ensure that free allocation continues to provide meaningful support to UK industry while maintaining the incentive to decarbonise and rewarding efficient installations. The amendments to the UK ETS will support its role as a key pillar of the UK’s climate policy. They demonstrate that we will take action to improve the scheme where necessary. I beg to move.
