Question to the Department for Business and Trade:

To ask His Majesty's Government what assessment they have made of deep-sea mining.

The UK recognises the potential impacts of deep sea mining are not fully understood and supports a moratorium on the granting of mining licences by the International Seabed Authority (ISA) until sufficient scientific evidence is available to assess the impact on marine ecosystems, and strong, enforceable environmental regulations, standards and guidelines are adopted by the ISA.

Through the UK's sponsorship of academic research and existing exploration licences, over 70 peer-reviewed publications supporting a greater understanding of environmental issues associated with deep sea mining have already been produced, with more to come.
