Question to the Department for Transport:

To ask the Secretary of State for Transport, what schemes and programmes her Department has in place to help support zero-emission in (a) shipping and (b) aviation.

The Government recognises the potential decarbonisation and growth benefits that new forms of zero-emission maritime vessels and aircraft could provide.

The Maritime Decarbonisation Strategy, published in March 2025, sets out our policies and commitments to decarbonise the sector. We are already meeting these commitments through the expansion of the UK Emissions Trading Scheme to domestic maritime from July 2026, and we will consult on maritime fuel regulations later this year.

We have announced a further £448 million of funding of the UK SHORE programme, the biggest government investment ever in the UK’s commercial maritime sector, which will unlock innovation and investment potential in UK technologies, ports and shipyards.

We will continue to work closely with maritime industry partners to help the sector unlock the investment it needs to transition to zero, and near-zero, emission fuels and technologies.

We have already made significant progress on aviation decarbonisation, with considerable support for sustainable aviation fuel (SAF), airspace modernisation and development of new technologies.

Alongside other measures, zero emission flight has a role to play in decarbonising the sector. In January, we announced up to £43m of R&D funding for aviation decarbonisation, including confirming our continued support of the Civil Aviation Authority’s (CAA) Hydrogen in Aviation Regulatory Challenge. This is informing the development of a regulatory framework for zero-emission hydrogen aircraft. Also, the Department for Transport (DfT) will publish shortly a report into the barriers and opportunities to commercialising hydrogen in aviation, completed by a Jet Zero Taskforce Task and Finish Group.
