Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty's Government what action they are taking with international partners to address the decline in marine oxygen levels linked to climate change and warmer seas.

We work extensively with international partners to reduce global greenhouse gas emissions, which is the main driver of warming seas and declining marine oxygen levels.

The UK is at the forefront of international action to tackle climate change. We played an influential role in securing the agreement of 195 countries to sign up to the Paris Agreement in 2015 and we remain fully committed to its implementation, as demonstrated by our instrumental role in the creation of a rulebook in Poland last year to bring the agreement to life.

The Intergovernmental Panel on Climate Change will publish a Special Report on Oceans and the Cryosphere later this year, which will include an up-to-date assessment of changes in the ocean due to climate change, including marine oxygen loss and its impacts. Once published we will respond to these findings in due course.
