The framework is built around five objectives: limit direct habitat destruction; protect a substantial share of marine areas from damaging or extractive activities; manage fishing and hunting outside protected areas; reduce pollution, especially runoff from land; and cut carbon dioxide emissions while strengthening ecosystems’ ability to cope with climate change.

It also outlines 12 principles for putting those objectives into practice. These include community stewardship, place-specific management, ecosystem-based planning, attention to cumulative impacts, precautionary and adaptive decisions, effective enforcement, good governance, and sustained funding and capacity. The article argues that more active interventions are needed in addition to existing approaches, not instead of them.
