BBNJ Negotiations: High Seas Treaty, UNCLOS and India’s Position (UPSC)

Study Notes · Environment & Ecology · General Studies · GS III

UPSC guide to BBNJ Treaty (High Seas Treaty) — UNCLOS framework, marine genetic resources, ABMTs, EIAs, capacity building and 2024–26 ratification status.

For the first time in history, the world has agreed on rules for the two-thirds of the ocean that belong to no one. On 19 June 2023, after nearly two decades of negotiation, UN member states adopted the Agreement on Marine Biological Diversity in Areas Beyond National Jurisdiction, popularly known as the BBNJ Treaty or the High Seas Treaty. India signed it on 25 September 2024 during the 79th UNGA session.

The high seas — every patch of ocean beyond 200 nautical miles from any coast — cover 64% of the ocean surface and 95% of its volume. They host the planet's largest carbon sink, half its photosynthesis, and species we have barely begun to discover. Until BBNJ, they were a legal black hole — a tragedy of the global commons. The treaty changes that.

This guide explains what the BBNJ Treaty is, how it relates to UNCLOS, what its four pillars cover, where ratification stands in 2024–26, and why it matters for India's blue economy and UPSC preparation.

What is BBNJ?

BBNJ stands for "Biodiversity Beyond National Jurisdiction". The full name is the Agreement under the United Nations Convention on the Law of the Sea (UNCLOS) on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction.

It is the third implementing agreement under UNCLOS, after:

Areas Beyond National Jurisdiction (ABNJ)

ABNJ refers to two zones of the ocean:

Together, ABNJ covers about 64% of the ocean surface and 49% of the Earth's surface.

Why a New Treaty Was Needed

BBNJ NEGOTIATIONS

UNCLOS, signed in 1982 and in force since 1994, is the constitution of the oceans. But it was drafted before the world understood:

A 2017 UN study showed that fewer than 1.4% of high seas were under any form of protection. Without a treaty, the 30% by 2030 ocean protection target adopted at CBD COP15 (Kunming-Montreal GBF, 2022) was mathematically impossible.

The result: a new instrument that fills four gaps in UNCLOS.

The Four Pillars of BBNJ

BBNJ NEGOTIATIONS key dimensions
BBNJ NEGOTIATIONS: key dimensions

The treaty rests on four substantive pillars, each addressing a gap in existing ocean law.

1. Marine Genetic Resources (MGRs) and Benefit Sharing

The dispute: developed countries with the technology to bioprospect MGRs (drugs, enzymes, cosmetics) wanted free access; developing countries argued MGRs are part of the "common heritage of mankind" and benefits must be shared.

The compromise:

2. Area-Based Management Tools (ABMTs), including Marine Protected Areas

The need: to protect ecologically and biologically significant areas in ABNJ.

Provisions:

This unlocks the path to the 30 by 30 target.

3. Environmental Impact Assessments (EIAs)

The need: to vet new activities — deep-sea mining, geoengineering, fishing in new areas — before damage is done.

Provisions:

4. Capacity Building and Transfer of Marine Technology (CB&TMT)

The need: to bridge the gap between developed and developing states in marine science.

Provisions:

Institutional Architecture

The treaty creates a robust institutional framework:

Ratification Status (2024–26)

The treaty enters into force 120 days after the 60th ratification. As of mid-2025:

Mains Hook

"The BBNJ Treaty fills a critical lacuna in UNCLOS. Discuss its four pillars and analyse its implications for India's blue economy and Deep Ocean Mission." — GS III

"Marine Genetic Resources are now recognised as part of the common heritage of mankind. Examine the BBNJ benefit-sharing regime and the position of developing countries." — GS III

"Without the BBNJ Treaty, the 30 by 30 ocean target is mathematically impossible. Comment." — GS III

Prelims Pointers

Conclusion

The BBNJ Treaty is the most important ocean agreement since UNCLOS itself. It transforms the high seas from a free-for-all into a managed global commons with rules for protected areas, equitable benefit-sharing, environmental safeguards and capacity building. For India — a country with a long coastline, growing blue economy ambitions and leadership pretensions in the Global South — ratification is not optional. It is the diplomatic and ecological investment of a generation.
