The UN report card states that, as of August 2020, 7.5% of the world’s marine area was in MPAs — including 17.2% of marine areas within national jurisdiction, and 1.2% of marine areas beyond national jurisdiction. These data are from the World Database on Protected Areas (WDPA), managed by the UN Environment Programme. (An alternative database on MPAs, the Marine Protection Atlas, notes that only 2.6% of the global ocean is in fully or highly protected zones.)
