Original consultation
Consultation description
The UK Emissions Trading Scheme (UK ETS) Authority (UK Government, Scottish Government, Welsh Government and the Department of Agriculture, Environment and Rural Affairs for Northern Ireland) is seeking input on a number of proposals to expand the scheme to the maritime sector.
We envisage that including maritime within the UK ETS can help overcome a key barrier to decarbonising the sector, which is that the prices of maritime fuels currently do not reflect their environmental costs. Including the maritime sector within the scheme could also strengthen the incentive to adopt low carbon fuels, and support deployment of fuel-efficient technologies and the introduction of fuel-efficient operating practices.鈥��犅�
The purpose of this consultation is to provide more detail and consult on the implementation of how maritime will be incorporated in the scheme from 2026 and to propose and consult on potential future expansion of the UK ETS to additional maritime emissions. In particular, it seeks views on:鈥犅�
- the scope of the scheme (definition of a domestic voyage, thresholds for inclusion, the inclusion of methane and nitrous oxide emissions and exemptions from the scheme)鈥�
- details around how to adjust the UK ETS cap to include emissions from the maritime sector鈥�
- participating in the scheme (regulatory regime and operator requirements, monitoring, reporting and verification, point of obligation and guidance)鈥�
- impacts of the scheme (decarbonisation impacts, potential distributional impacts and carbon leakage risk; equality considerations)
- potential future expansion of the UK ETS to additional maritime emissions, with a future review of the threshold and coverage of international routes
This consultation is open to anyone, but we expect it to be of greatest interest to:鈥�
- the shipping industry鈥�
- non-governmental organisations (NGOs)鈥�
- academics and thinktanks鈥�
- any individual or organisation that has an interest, directly or indirectly in the expansion of the UK ETS and/or the adjustment to the cap of the scheme
