In the shadow of the BBNJ negotiations and dawn of the new regime, the present period offers a unique opportunity to evaluate the finalised text ahead of its animation by individual state actors. Of particular interest are provisions for MPAs, which are widely perceived as the preferred method of achieving ambitious biodiversity and sustainable development goals. To evaluate the BBNJ’s contribution towards potential high sea MPAs, it is first worth establishing an understanding of the existing governance framework for MPAs. Such a study will lay the foundation for a future comprehensive assessment of the finalised treaty text and substantiate hypotheses regarding the BBNJ’s ability to affect successful environmental management on the High Seas.
