In July 2019, the Greenpeace report “In Deep Water” warned: “By impacting on natural processes that store carbon, deep sea mining could even make climate change worse by releasing carbon stored in deep sea sediments or disrupting the processes which ……. deliver it to those sediments. Deep sea sediments are known to be an important long-term store of ‘blue carbon’, the carbon that is naturally absorbed by marine life, a proportion of which is carried down to the sea floor as those creatures die.”
