UK Faces Pivotal Year as CCAMLR Chair to Advance Southern Ocean Protection and 460,000 km² Marine Protected Area

The United Kingdom holds the chair of the Commission for the Conservation of Antarctic Marine Living Resources until the end of October and will preside over the 45th annual meeting this year, an opportunity that former UK environment minister Zac Goldsmith argues could deliver the most significant Antarctic conservation outcome in a generation. The agenda includes the creation of a 460,000 square kilometre marine protected area around the Antarctic Peninsula proposed by Argentina and Chile, the adoption of a Krill Fisheries Management Approach, and a credible roadmap to achieve 30 percent Southern Ocean protection by 2030.

 

Strategic Significance of the Southern Ocean

 

The Southern Ocean is not just another stretch of ocean requiring protection. It functions as one of the principal engines of the global climate system, regulating temperature, circulation, and carbon flows in ways that have far-reaching implications for the rest of the planet. The Antarctic Peninsula alone is home to roughly a third of the global krill population, which in turn supports populations of whales, penguins, seals, seabirds, and fish across a productive marine food web. The region remains one of the last places on Earth where natural systems operate largely on their own terms, and its protection is therefore strategically important for both regional biodiversity and global climate stability.

 

Krill Fishery Pressure and Ecological Stress

 

The pressure on Southern Ocean ecosystems has intensified sharply in recent years. Three consecutive years of record-low sea ice have disrupted krill reproduction cycles, and last year the krill fishery hit its 620,000 metric tonne catch limit for the first time in history, closing three months earlier than scheduled. Industrial fleets operating from Norway, China, South Korea, Chile, and Ukraine are extracting krill at a pace that an already stressed ecosystem cannot absorb sustainably. The cumulative effect is a tightening squeeze on a foundational species that supports the entire Southern Ocean food web, with consequences that extend well beyond the krill fishery itself.

 

Certification Controversy and Governance Stalemate

 

The Marine Stewardship Council's recent decision to recertify the Antarctic krill fishery as sustainable despite an outdated stock assessment and mounting evidence of localised harm to whale and penguin populations has drawn legal challenge. The deeper issue, however, is not certification but the long-running stalemate in international governance that has left the Southern Ocean without the protection it requires. CCAMLR operates by consensus, which means any single member country can effectively block negotiations. This decision-making structure has provided legitimacy but has also produced years of stagnation despite mounting scientific evidence of ecosystem stress.

 

CCAMLR-45 Agenda and Domain 1 Marine Protected Area

 

The 45th annual CCAMLR meeting offers three interconnected opportunities for progress. The first is the creation of a vast marine protected area proposed by Argentina and Chile covering the waters around the Antarctic Peninsula. The proposed Domain 1 MPA covers 460,000 square kilometres, larger than Germany, and would protect the area where ecological pressure is most acute. Three further MPAs are under negotiation, but agreement on Domain 1 alone would represent a landmark achievement for international marine governance. The proposal has been on the table for several years, and the political and ecological case for its adoption has continued to strengthen.

 

Krill Fisheries Management Approach

 

The second priority is the adoption of a Krill Fisheries Management Approach to govern how krill catches are distributed and managed across the Antarctic Peninsula region. There is currently no agreement on appropriate catch limits, and tensions among member states reflect both economic interests and differing scientific interpretations of ecosystem capacity. Any credible framework would need to spread catches across smaller management units, use whale populations as indicators of ecosystem health, and include enforceable mechanisms to reduce fishing rapidly if damage is detected. The MPA proposal and the fisheries management approach are tightly linked and need to be negotiated together to deliver coherent outcomes.

 

Roadmap Toward 30 Percent Protection by 2030

 

The third priority is a credible roadmap with binding benchmarks and specific dates to achieve 30 percent protection of the Southern Ocean by 2030. CCAMLR itself committed to this objective in 2009, and the absence of demonstrable progress since then has undermined the credibility of the institution and the broader principle of consensus-based marine governance. A clear vision of where the protection process is heading would help address concerns around sovereignty, resource access, and Antarctic governance that have fuelled scepticism among some member states. The 30 by 30 framing also aligns with the broader Kunming-Montreal Global Biodiversity Framework that commits the international community to protecting 30 percent of the ocean by 2030.

Industry Engagement and Aker BioMarine

 

A significant change in the political landscape is the engagement of Aker BioMarine, the Norwegian company that accounts for more than 60 percent of the krill catch. The company has launched an Ocean Stewardship Initiative aimed at bringing industry behind protected area proposals, signalling a fundamental shift in the alignment between fishing interests and conservation outcomes. When the dominant operator in a fishery actively supports conservation measures, the political dynamics of multilateral negotiations change in ways that would have seemed unlikely only a few years ago. The shift reflects a broader recognition within parts of the krill industry that long-term commercial viability depends on the integrity of the ecosystem on which the fishery is based.

 

Aligned International Support

 

A range of governments and institutions have positioned themselves in support of stronger Southern Ocean protection. South Africa made Antarctica a national priority during its G20 presidency. Chile's new foreign minister chose the continent as his first official overseas destination. The European Union has made Southern Ocean MPAs a flagship element of its Ocean Pact. The combination of industry engagement, supportive governments, and the structural backing of the Kunming-Montreal framework creates one of the strongest international architectures for an Antarctic conservation breakthrough in recent decades. The convergence of these factors significantly increases the probability of meaningful progress at CCAMLR-45.

 

UK Historical Position and Chair Opportunity

 

The United Kingdom has a long-standing relationship with Antarctica that stretches from the age of exploration to its role as a founding signatory of the 1959 Antarctic Treaty. Britain proposed the world's first high seas MPA at the South Orkney Islands in 2009, has strengthened protections around South Georgia and the South Sandwich Islands, and has built its own Antarctic Strategy around the goal of a system of marine protected areas by 2030. The UK's tenure as CCAMLR chair, combined with King Charles III's long-standing personal commitment to ocean conservation and the current alignment of political will among key members, provides a rare opportunity to deliver structural progress.

 

Political Timing and Preparation Requirements

 

Experience with CCAMLR negotiations suggests that what has not been informally agreed in the run-up to the meeting is unlikely to be formally agreed at the meeting itself. Negotiators typically arrive with preset positions and limited flexibility to compromise once formal negotiations begin. The implication is that the political work needed to secure agreement on Domain 1, the Krill Fisheries Management Approach, and the 30 by 30 roadmap must happen now, in the months leading up to CCAMLR-45. The UK chairmanship provides both the platform and the responsibility to drive this preparatory work, leveraging diplomatic relationships, scientific input, and industry engagement to align member states ahead of the formal meeting.

 

Implications for Multilateralism and Ocean Governance

 

Beyond the specific Antarctic conservation outcomes at stake, CCAMLR-45 has significance for the broader credibility of multilateral environmental governance. Goldsmith has argued that a successful outcome would send a powerful signal, at a time when multilateralism is under strain, that countries can still come together around shared values and act for the global good. The credibility of consensus-based decision-making in international fora has been increasingly questioned in recent years, with multiple international processes failing to deliver outcomes proportionate to the scale of underlying environmental challenges. A breakthrough at CCAMLR-45 would provide a counterexample, demonstrating that effective multilateral action remains possible when political will, industry alignment, and scientific consensus converge.

 

Outlook for Southern Ocean Conservation

 

The Southern Ocean represents one of the most consequential and least protected marine ecosystems in the world, and the next several months will determine whether the international community can deliver the structural reforms needed to safeguard it. The combination of intensifying ecological stress, growing political and industry support, and the UK's chairmanship of CCAMLR creates conditions that may not be replicated for several years. Failure to act decisively at CCAMLR-45 would extend a decade of governance stalemate at a time when the Antarctic ecosystem is showing increasingly clear signs of stress. Success, by contrast, would deliver tangible protection for one of the planet's most important marine ecosystems and reinforce the broader effort to meet 30 by 30 commitments across the world's oceans.
