Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how much investment in the Royal Navy fleet will be required to meet the terms of international agreements to reduce the environmental impact of the maritime fleet.

The Royal Navy is developing plans to reduce greenhouse gas emissions from warships and Auxiliaries. With regards other vessel emissions: the Royal Navy aims to meet the requirements of International Maritime Organisations (IMO) Conventions and the provisions of the UN Convention on the Law of the Sea to protect the environment where this can be done without compromising operations or operating capability.

The Royal Navy is working closely with industrial partners to reduce the environmental impact of the Fleet.

Naval ships currently coming into service will have the equipment to reduce oxides of nitrogen to the latest IMO requirements and the Ministry of Defence is already using ultra-low sulphur fuels to minimise sulphur and particulate emissions from combustion exhaust gasses.
