The report argues that South Africa must elevate the Southern Ocean and Antarctica in its strategic planning, as the region is critical for global climate regulation, food security, and maritime safety. While South Africa is the only African state party to the Antarctic Treaty, its diplomatic engagement has been inconsistent. The document highlights rising risks from climate change, such as sea-level rise threatening African coasts, and geopolitical tensions, including Russia's seismic surveying and the blocking of Marine Protected Areas by China and Russia. It suggests South Africa leverage its non-claimant status and role as a logistical gateway to enhance its influence, while warning that its under-resourced navy may struggle with increasing search and rescue demands from growing Antarctic tourism and rerouted shipping traffic around the Cape of Good Hope.

The High Seas Treaty, formally the Agreement on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction (BBNJ agreement), enters into force on January 17, 2026. It establishes a global framework to protect biodiversity in international waters, which cover roughly two-thirds of the ocean and previously lacked comprehensive governance. The treaty is built on four pillars: area-based management tools (including marine protected areas), rules for sharing benefits from marine genetic resources, capacity building and technology transfer for low-income countries, and standardized environmental impact assessments for activities like marine carbon dioxide removal. While it does not replace Regional Fisheries Management Organisations (RFMOs) for setting quotas, it aims to influence fisheries through ecosystem-based management. As of January 15, 2026, 83 parties have ratified the agreement. Implementation now depends on the BBNJ Preparatory Commission and the first Conference of Parties (BBNJ COP) to finalize governing structures, financial mechanisms, and operational logistics.

The report analyzes maritime security in the Western Indian Ocean (WIO), emphasizing that threats like climate change, illegal fishing, and piracy are interconnected. It highlights the risks of increasing militarisation by global powers and the environmental dangers of rerouting shipping around the Cape of Good Hope due to Red Sea instability.

The report analyzes marine geoengineering, dividing it into marine carbon dioxide removal (mCDR) and marine solar radiation modification (SRM). It argues that these speculative technologies pose irreversible risks to ocean ecosystems and human rights, while facing significant monitoring and verification challenges. The authors contend that proposed deployment zones span every ocean basin, making the impacts inherently transboundary and potentially violating international law, including the CBD moratorium and UNCLOS.

The report assesses the current state of spatial management in the Southern Ocean, highlighting the tension between CCAMLR's conservation mandate and the 'rational use' of marine resources. It identifies a deadlock in the establishment of new Marine Protected Areas (MPAs) due to eroding consensus and geopolitical tensions. The authors suggest transitioning from a narrow focus on MPA designation toward a comprehensive Marine Spatial Planning (MSP) approach to better integrate land-sea conservation and respond to climate change impacts.

The report examines the 'blue corridors' of the Eastern Pacific Ocean, from the Bering Strait to the Antarctic Peninsula, highlighting how these migratory routes are essential for whale survival and ocean health. It details cumulative threats including ship strikes, fisheries bycatch, ghost gear, underwater noise, and climate change. The document advocates for the implementation of connected networks of Marine Protected Areas (MPAs) and Other Effective Area-based Conservation Measures (OECMs) to meet the global 30x30 target, while proposing specific regional initiatives like the Eastern Tropical Pacific Marine Corridor (CMAR) and the Global Oceans Treaty (BBNJ) to protect whales in international waters.

The report evaluates seven ocean-based carbon dioxide removal (CDR) strategies: coastal blue carbon restoration, seaweed cultivation, ocean fertilization, artificial upwelling, alkalinity enhancement, electrochemical techniques, and artificial downwelling. It finds that most of these methods are in early development with significant scientific gaps and environmental risks. The authors argue that current international legal frameworks, such as UNCLOS and the CBD, are insufficient to proactively regulate these technologies. To address this, the report recommends increasing funding for collaborative research, establishing an international code of conduct for at-sea trials, and developing a comprehensive global governance regime to manage transboundary impacts and ensure equitable benefit sharing.

The report argues that krill fishing is inherently unsustainable as it threatens a fragile ecosystem already stressed by climate change. It highlights the dominance of Aker BioMarine in the market and identifies numerous European retailers and aquaculture companies that use krill-based feed or sell krill oil supplements. The document criticizes the Marine Stewardship Council (MSC) certification for failing to account for climate change and predator impacts, and calls for an immediate moratorium on krill fishing.

The report argues that krill fishing is inherently unsustainable as it threatens a fragile ecosystem already stressed by climate change. It highlights the dominance of Aker BioMarine in the market and identifies numerous European retailers selling salmon fed with krill meal. The document criticizes the Marine Stewardship Council (MSC) certification for ignoring climate change effects and calls for an immediate moratorium on krill fishing.

The report argues that Antarctic krill fishing is unsustainable, threatening a fragile ecosystem already stressed by climate change. It highlights how the industry, dominated by Aker BioMarine, uses greenwashing and problematic certifications like the MSC to justify its operations. An investigation reveals that krill-oil supplements are widely sold by the world's largest retailers and krill meal is extensively used in European salmon aquaculture, often without consumer-facing labels or retailer policies to exclude it.

The report argues that whales are sentinel species for ocean health and critical for climate regulation, but face imminent extinction risks from cumulative threats. It advocates for 'connectivity conservation' through the establishment of blue corridors and networks of Marine Protected Areas (MPAs) to safeguard migratory routes across national and international waters.

The report evaluates UK supermarkets' reliance on fishmeal and fish oil (FMFO) for farmed seafood, arguing that the current 'fed aquaculture' model is unsustainable and threatens marine ecosystems and global food security. It ranks retailers based on their policies, transparency, and in-store practices, finding that none have a time-bound target to eliminate wild-caught fish in feed.

The statement advocates for a non-market platform connecting the UNFCCC Paris Agreement and the Antarctic Treaty System (ATS) to collectively account for carbon stocks in the Southern Ocean. It highlights that Antarctic blue carbon sites, which are expanding as ice melts, could store up to 160 million tonnes of carbon annually and act as a major natural negative feedback on climate change. By utilizing the ATS's existing framework where sovereignty claims are suspended, the authors suggest a way to bypass diplomatic obstacles to conservation and avoid conflicts over individual Nationally Determined Contributions (NDCs).

The document examines Spain's dual-track legal system for combating IUU fishing, highlighting the success of administrative sanctions—such as the 25 million euro penalties from Operations Sparrow I and II—while contrasting this with the failure of criminal prosecutions in external waters, specifically the Supreme Court's dismissal of charges against Vidal Armadores due to jurisdictional limits.

The report documents WWF's half-century of cetacean conservation, emphasizing the transition from lethal research to non-invasive methods and the importance of multi-stakeholder collaboration. Key achievements include the 1986 commercial whaling moratorium, the creation of the Ross Sea Marine Sanctuary, and the re-routing of shipping lanes in the Bay of Fundy. However, the report also highlights the critical failure to save the vaquita porpoise due to illegal gillnet fishing. It concludes by introducing the WWF Cetacean Global Initiative, focusing on bycatch, shipping, and critical habitat protection.

The Living Blue Planet Report 2015 documents a 49% decline in global marine vertebrate populations between 1970 and 2012. It highlights critical losses in key habitats, including over half of reef-building corals in tropical reefs over 30 years and nearly 20% of mangrove cover between 1980 and 2005. The report identifies overfishing, climate change, pollution, and extractive industries as primary drivers of this degradation. It emphasizes the socio-economic risks, noting that nearly 3 billion people rely on fish as a major protein source and that the ocean generates at least US$2.5 trillion in annual economic benefits. The document advocates for the 'One Planet Perspective' framework, which includes expanding Marine Protected Areas (MPAs) to 30% to potentially generate up to US$920 billion by 2050.

The document analyzes a spectrum of decision-making models in international law, ranging from strict consensus to majority voting, to identify effective procedures for managing highly migratory fish stocks in the Western and Central Pacific.

The report highlights that tropospheric ozone is a potent greenhouse gas and air pollutant responsible for approximately 0.23°C of present-day warming and nearly 500,000 premature deaths annually. It is not emitted directly but forms from precursors like methane, nitrogen oxides (NOx), non-methane volatile organic compounds (NMVOCs), and carbon monoxide (CO). The document identifies a significant gap in global climate strategies, noting that tropospheric ozone is largely absent from the Paris Agreement and most Nationally Determined Contributions (NDCs). It provides sector-specific policy levers—ranging from methane capture in oil and gas to electric vehicle adoption in transport—and presents case studies from Los Angeles, Mexico City, Beijing, and Europe to demonstrate the effectiveness of targeted pollution control. The report concludes with recommendations for policymakers to adopt multi-pollutant approaches, for scientists to fill knowledge gaps in regional climate effects, and for funders to increase the currently insufficient international development funding for outdoor air pollution.

The document argues that over 40 percent of the marine environment is already affected by a combination of global stressors, such as ocean warming and acidification, and local stressors, such as overfishing and pollution. It highlights that these stressors often interact synergistically, increasing the vulnerability of specific hotspots like the Arctic and ecosystems like coral reefs. The text emphasizes that while global stressors are driven by CO2 emissions, managing local stressors can buffer ecosystems and increase resilience, necessitating a cross-scale governance approach that integrates local action with global climate policy.

The report argues that the ocean is a victim of global market failure, where the true value of its ecosystems and services is ignored. It identifies six primary threats—ocean acidification, warming, hypoxia, sea level rise, pollution, and overexploitation of resources—and emphasizes that these stressors often interact synergistically. The authors quantify the 'cost of inaction' by comparing low and high emission scenarios, estimating that avoidable damages could exceed US$ 1 trillion per year by 2100. The document advocates for a shift from traditional cost-benefit analysis to a precautionary, insurance-based risk model and calls for integrated, cross-scale ocean governance to build ecosystem resilience.
