I thank noble Lords for their contributions. I am particularly grateful to the noble Lord, Lord Teverson, for sharing his holiday experiences with us all. I expect he will bring his photograph album next time. I was going to say that it would show him lying on the beach but, of course, there are no beaches in Switzerland; perhaps he will be lying on the lakeside in Switzerland. I am grateful to both noble Lords for their support for these proposals and their questions.
This Order in Council, as it will be, will enable the inclusion of flights from Great Britain to Switzerland within the definition of aviation activity and bring them within the scope of the UK ETS for the start of the 2022-23 scheme year. As I said, we will seek to include flights from Northern Ireland as soon as the Northern Ireland Assembly is functioning.
In response to the noble Baroness, Lady Blake, although UK-Switzerland flights amount to approximately a quarter of a megaton of CO2, which is less than 0.2% of the UK ETS cap for the 2023 scheme year, this legislation will enable us to uphold our agreements with Switzerland and the UK Government’s commitment to the 2020 government response. Clearly the proposals will ] not have a significant impact on the costs of participating in the UK ETS for the vast majority of participants, although aircraft operators running flights between Switzerland and Great Britain will of course see a slight increase in their obligations as a result of the expanded scope.
As the noble Lord, Lord Teverson, correctly stated, to reduce the risk of carbon leakage, a proportion of UK ETS allowances are allocated to aircraft operators for free, which they can use towards their scheme obligations, and flights from Great Britain to Switzerland will be able to apply for a free allocation entitlement. In the Government’s response to the Future of UK Carbon Pricing consultation, we committed to reviewing the UK’s approach to free allocations to ensure that carbon leakage is appropriately mitigated. It supports the UK’s high climate objectives and preserves the incentive to decarbonise, which is what we want. The commissioned economic research on aviation carbon pricing found minimal risks of carbon leakage for the aviation sector under the current scope of the UK ETS, and the consultation proposed three potential phase-out trajectories of aviation-free allocation. The consultation also explored potential updates to the UK ETS free allocation methodology, including benchmarking and updating activity data and how we account for new operators.
