Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what steps his Department is taking to tackle the effect of ocean acidification; and what progress has been made in implementing the recommendations from the Ocean Acidification Research Programme.

As the Intergovernmental Panel on Climate Change Special Report on the Ocean and Cryosphere in a Changing Climate has stated, increasing emissions of carbon dioxide will result in greater levels of ocean acidification. The most effective way to reduce the impacts of climate change and acidification on our ocean is to reduce emissions. The UK Government has therefore set a legally binding target to achieve net zero greenhouse gas emissions by 2050.

From 2010-16, Defra partnered with the Natural Environment Research Council and the Department for Business, Energy and Industrial Strategy to invest £12.4 million in the UK Ocean Acidification Research Programme. This programme provided baseline data on ocean acidification for UK seas and supported the development of long-term monitoring strategies. The outputs from this ground-breaking initiative contributed evidence which has fed into the cross-Government Climate Change Adaptation programme and the Intergovernmental Panel on Climate Change 5th Assessment Report. The UK has also supported the inclusion of ocean acidification monitoring in the OSPAR Convention for the Protection of the Marine Environment of the North East Atlantic, the UN Sustainable Development Goals and through other international policy initiatives.

In 2018, building on the UK Ocean Acidification programme, Defra’s Science Advisory Council reviewed the national monitoring and assessment programmes for ocean acidification and provided advice on where the UK could contribute to global monitoring. As a result of this we have now established the North East Atlantic Ocean Acidification Hub in the UK which forms part of the Global Ocean Acidification Observing Network. This Defra-funded hub acts as the European regional centre on monitoring and research. An Ocean Acidification Hub workshop was held in London in 2019 to foster collaboration and share information on ocean acidification monitoring and modelling across communities, to encourage and ease the data-submission process via the Global Ocean Acidification Portal, promote best practices and build capacity for further training.

We also recognise the importance of global research collaboration and have joined the Commonwealth Blue Charter Action Group on Ocean Acidification, sharing our knowledge and science with our international partners.
