As a treaty to protect the High Seas entered into force this month with backing from more than 80 countries, major fishing nations China, Japan and Brazil secured a last-minute seat at the table to negotiate the procedural rules, funding and other key issues ahead of the treaty’s first COP.

The Biodiversity Beyond National Jurisdiction (BBNJ) pact – known as the High Seas Treaty – was agreed in 2023. It is seen as key to achieving a global goal to protect at least 30% of the planet’s ecosystems by 2030, as it lays the legal foundation for creating international marine protected areas (MPAs) in the deep ocean. The high seas encompass two-thirds of the world’s ocean.

Last September, the treaty reached the key threshold of 60 national ratifications needed for it to enter into force – a number that has kept growing and currently stands at 83. In total, 145 countries have signed the pact, which indicates their intention to ratify it. The treaty formally took effect on January 17.

    “In a world of accelerating crises – climate change, biodiversity loss and pollution – the agreement fills a critical governance gap to secure a resilient and productive ocean for all,” UN Secretary-General António Guterres said in a statement.

    Julio Cordano, Chile’s director of environment, climate change and oceans, said the treaty is “one of the most important victories of our time”. He added that the Nazca and Salas y Gómez ridge – off the coast of South America in the Pacific – could be one of the first intact biodiversity hotspots to gain protection.

    Scientists have warned the ocean is losing its capacity to act as a carbon sink, as emissions and global temperatures rise. Currently, the ocean traps around 90% of the excess planetary heat building up from global warming. Marine protected areas could become a tool to restore “blue carbon sinks”, by boosting carbon absorption in the seafloor and protecting carbon-trapping organisms such as microalgae.

    Last-minute ratifications

    Countries that have ratified the BBNJ will now be bound by some of its rules, including a key provision requiring countries to carry out environmental impact assessments (EIA) for activities that could have an impact on the deep ocean’s biodiversity, such as fisheries.

    Activities that affect the ocean floor, such as deep-sea mining, will still fall under the jurisdiction of the International Seabed Authority (ISA).

    Nations are still negotiating the rules of the BBNJ’s other provisions, including creating new MPAs and sharing genetic resources from biodiversity in the deep ocean. They will meet in one last negotiating session in late March, ahead of the treaty’s first COP (conference of the parties) set to take place in late 2026 or early 2027.

    China and Japan – which are major fishing nations that operate in deep waters – ratified the BBNJ in December 2025, just as the treaty was about to enter into force. Other top fishing nations on the high seas like South Korea and Spain had already ratified the BBNJ last year.

    Power play: Can a defensive Europe stick with decarbonisation in Davos?

    Tom Pickerell, ocean programme director at the World Resources Institute (WRI), said that while the last-minute ratifications from China, Japan and Brazil were not required for the treaty’s entry into force, they were about high-seas players ensuring they have a “seat at the table”.

    “As major fishing nations and geopolitical powers, these countries recognise that upcoming BBNJ COP negotiations will shape rules affecting critical commercial sectors – from shipping and fisheries to biotechnology – and influence how governments engage with the treaty going forward,” Pickerell told Climate Home News.

    Some major Western countries – including the US, Canada, Germany and the UK – have yet to ratify the treaty and unless they do, they will be left out of drafting its procedural rules. A group of 18 environmental groups urged the UK government to ratify it quickly, saying it would be a “failure of leadership” to miss the BBNJ’s first COP.

    Finalising the rules

    Countries will meet from March 23 to April 2 for the treaty’s last “preparatory commission” (PrepCom) session in New York, which is set to draft a proposal for the treaty’s procedural rules, among them on funding processes and where the secretariat will be hosted – with current offers coming from China in the city of Xiamen, Chile’s Valparaiso and Brussels in Belgium.

    Janine Felson, a diplomat from Belize and co-chair of the “PrepCom”, told journalists in an online briefing “we’re now at a critical stage” because, with the treaty having entered into force, the preparatory commission is “pretty much a definitive moment for the agreement”.

    Felson said countries will meet to “tidy up those rules that are necessary for the conference of the parties to convene” and for states to begin implementation. The first COP will adopt the rules of engagement.

    She noted there are “some contentious issues” on whether the BBNJ should follow the structure of other international treaties such as the Convention on Biological Diversity (CBD), as well as differing opinions on how prescriptive its procedures should be.

    “While there is this tension on how far can we be held to precedent, there is also recognition that this BBNJ agreement has quite a bit to contribute in enhancing global ocean governance,” she added.

    EU carbon credits could supercharge world’s clean cooking push, France says

    Published

    on

    The European Union’s plan to use international carbon credits to help meet its 2040 climate target could provide a “super solution” to accelerate the rollout of cleaner cooking technologies across the Global South, according to France’s top climate envoy .

    With the bloc set to become a “big investor” in carbon credits as a result of its new climate law, efforts to replace polluting cooking stoves with cleaner alternatives could be scaled up, French climate ambassador Benoît Faraco told a summit on clean cooking hosted by the International Energy Agency (IEA).

    Faraco said he had discussed that possibility with French fossil fuel giant TotalEnergies, which is involved in clean cooking offsetting programmes in Africa and has major plans to expand the adoption of liquefied petroleum gas (LPG) for use in cookstoves in developing countries.

    Controversial carbon credits

    Starting in 2036, the EU will be allowed to count “high-quality” international carbon credits generated by partner countries under Article 6 of the Paris Agreement towards up to 5% of the emissions reductions required to meet its 2040 target of cutting greenhouse gas emissions by 90%. Several climate experts and activists accused the bloc of watering down its commitments by including carbon credits in its climate target for the first time.

    The amended climate law adopted in early February says the credits will need to follow “robust safeguards” and “ensure environmental integrity”. The European Commission and its member states have yet to determine which types of credits would qualify or how they would be sourced.

    But a French diplomatic source, speaking on condition of anonymity, told Climate Home News that clean cooking should be considered among the sectors to be supported through Article 6 funding, adding that France was willing to engage with its partners on the topic.

      Clean cooking credits have regularly faced significant criticism from researchers and campaigners who argue that climate benefits are often exaggerated and weak monitoring can undermine claims of real emission reductions.

      “There is a significant risk in trading credits that have repeatedly failed to deliver on their promises, which has been a particular issue with cookstove projects,” said Benja Faecks, an expert at Brussels-based NGO Carbon Market Watch (CMW), adding that it was “far too early” for France to make recommendations on specific credit types.

      The French diplomatic source told Climate Home News that France will continue to advocate for the EU to forge partnerships with countries to develop a high-quality carbon credits supply chain.

      Total’s cooking gas expansion

      Speaking at the IEA summit held in Paris late last month, Faraco said he had discussed the use of carbon credits to fund clean cooking initiatives with TotalEnergies a few days earlier when he joined the French multinational on a visit to deliver LPG cooking units.

      TotalEnergies says it is investing over $400 million in LPG infrastructure – including canister storage and filling stations – to give 100 million people in Africa and India access to cleaner cooking alternatives to wood and charcoal.

      But while the company promotes the programme as a win for public health and the climate, it also stands to benefit commercially: the rollout would create a vast new market to absorb the growing volumes of oil and gas the company wants to produce across Africa.

      In Uganda, where TotalEnergies is leading the development of a major and controversial oil drilling project on the shores of Lake Albert, the French firm says it also provides “affordable” LPG cooking solutions to local communities aiming to avoid “critical deforestation”.

      Campaigners have said that gas is not clean nor affordable and pushing its adoption for cooking would lock vulnerable communities into a fossil fuel system. Faecks from CMW said the distribution of LPG cookstoves “very much suits Total’s interests”.

      TotalEnergies did not immediately respond to a request for comment.

      Major carbon market player

      The French company has long been involved in carbon markets and, in 2025, spent $73 million to buy carbon credits used to offset, on paper, the greenhouse gas emissions caused by its oil and gas operations.

      Last year, it announced that it had partnered with a carbon credit developer to distribute 200,000 cookstoves to households in Rwanda that it said would prevent the emission of more than 2.5 million tons of carbon dioxide over the next 10 years. TotalEnergies will acquire the credits produced by the project and use them from 2030 to offset some of its direct emissions.

      “Clean cooking contributes to long-term social, economic and human development in a more sustainable way,” Arnaud Le Foll, senior vice-president new business and carbon neutrality at TotalEnergies, said at the time.

      Explainer: Will AI data centres make or break the energy transition?

      Published

      on

      For tech entrepreneur Elon Musk, the answer to the rocketing energy needs of artificial intelligence (AI) data centres is to launch them into space, where they could tap limitless energy from the sun. But until that happens, the places on Earth where these number-crunching mega-hubs are located face big spikes in electricity demand to run them.

      In the US, this has sparked fears of higher energy prices for consumers. To allay those concerns, President Donald Trump will reportedly convene big tech firms this week to sign a pledge to provide or pay for the extra energy supplies they will need as their AI data centres expand.

      According to the International Energy Agency (IEA), data centres accounted for 1.5% of electricity demand worldwide in 2024 – a share set to rise to about 3% by 2030. Overall, data centre demand is expected to more than double to about 945 terawatt-hours (TWh) by then, which is slightly above the electricity consumption of Japan today.

      AI data centres, where AI models are trained and deployed, put far more strain on power supplies than traditional data centres, which each use between 10 and 25 megawatts (MW). In comparison, demand from a “hyperscale” AI centre can exceed 100 MW at any given time, which if running at full capacity could consume as much electricity in a year as 100,000 households.

      We look at where this power might come from and whether, as some warn, AI is going to blow the world’s efforts to transition away from fossil fuels out of the water.

      Why does AI need so much electricity?

      AI data centres differ in how they use electric power. In a conventional data centre, data requests from businesses, individuals and other users come in a randomised way, translating into a steady load level on the servers, with relatively little fluctuation in demand.

      But in an AI data centre, processors need to go through training or learning periods, using so-called “graphical processing units”. These are synchronised, being started up and switched off at the same time. This translates into “power bursts”, which last just a few seconds, but happen very frequently and concurrently, according to Gerhard Salge, chief technology officer at Hitachi Energy.

      “That is a different challenge than just providing the power and the energy for the conventional data centres,” he told journalists at the International Renewable Energy Agency assembly in Abu Dhabi earlier this year.

      Here, officials and business executives discussed how to meet those demand peaks, noting they cannot be dealt with just by installing huge batteries as those would wear out quickly.

      Martin Pibworth, chief executive of SSE, a Scotland-based energy firm, said AI-led demand will put pressure on the power system, but “the problem we all have is no one really knows the pace and trajectory of that demand lift”. In the UK, the government’s Clean Power Plan will be needed to make sure electricity operators can meet demand from AI and other data centres as more come online, he added.

        In the US, meanwhile, the Trump administration is eager to ensure that communities that are home to data centres, as well as the wider public, do not turn against the industry due to its perceived unfairly high use of energy and water.

        Ahead of a meeting scheduled on March 4, where US tech titans are due to sign a pledge on powering their own data centres, White House spokesperson Taylor Rogers told CNBC: “Under this bold initiative, these massive companies will build, bring, or buy their own power supply for new AI data centres, ensuring that Americans’ electricity bills will not increase as demand grows.”

        Will electricity for data centres and AI come from clean or dirty sources of energy?

        The answer to this question is key to how countries tackle climate change, as it will affect their energy mix, how electricity is produced and distributed, and therefore the trajectory of their greenhouse gas emissions. Decisions made by governments and businesses will shape how the AI industry powers the technology on which it relies.

        Under pro-fossil fuel Trump, the US has walked away from policy support for clean energy, meaning data centre operators can choose their energy sources freely. In January, data from Global Energy Monitor (GEM) showed the US now has the most gas-fired power capacity in development, surpassing China and accounting for nearly a quarter of the world’s total.

        More than one-third of this capacity is set to directly power data centres on-site, in hotspots like Texas, and many more grid-connected gas-fired projects are planned to meet an expected increase in energy demand from AI, GEM said.

        On the other hand, some tech companies – especially multinationals – have set goals to cut their emissions to net zero, and so are choosing to power their data centres with renewables, including in the US.

        For example, French energy giant TotalEnergies recently signed two long-term Power Purchase Agreements (PPA) to deliver 1 gigawatt (GW) of solar capacity for Google’s data centres in Texas. This followed two other PPAs with Google for 1.2 GW secured by Clearway, a California-based renewables company 50%-owned by TotalEnergies.

        (Source: IEA, Paris, Licence: CC by 4.0)

        Some countries are also moving to ensure the power needed for AI and the data centre industry is produced using clean energy.

        In Ireland, an effective ban on new data centre connections was lifted in December, provided at least 80% of the centres’ annual energy demand is met by new renewable electricity sources. The government also plans to build Green Energy Parks, where data centres can be located alongside renewables plants to avoid straining the national grid.

        Salge of Hitachi Energy said that with big investors wanting to drive investment in AI data-crunching so fast, “there is no other power generation technology than variable renewables which you can build in such a timeline” of two to three years. “Anything else will be in the 2030s and later,” he added.

        Some governments – such as Sweden’s centre-right coalition have proposed nuclear as a clean energy solution for AI data centres, saying they could fuel a “renaissance”. But building nuclear power plants requires massive investment and long timelines, while new small-scale modular reactors are not yet commercially available.

        How are power systems and regulators coping so far?

        In a February report forecasting electricity demand out to 2030, the IEA said AI and data centres are contributing to generation growth in advanced economies, which is now accelerating again after 15 years of stagnation. However, it flagged bottlenecks in connecting new data centres, because grids are not being built or improved fast enough to keep up with rising power demand, forcing big customers to wait.

        The report noted that at least 150 GW of queued data centre projects are estimated to be in the advanced stages, while one-fifth of the global data centre build-out is at risk of delay due to grid congestion.

        Comment: Using energy-hungry AI to detect climate tipping points is a paradox

        Planning, permitting and completing new grid infrastructure can take five to 15 years, whereas data centres need one to three years. Prices for key grid components have also nearly doubled over the past five years, the IEA noted.

        The European Commission, meanwhile, aims to support those operators that can save on energy use. It plans to adopt a “Data Centre Energy Efficiency Package” in April that will contain an assessment of data submitted under a reporting scheme, introduce a rating scheme for data centres in the EU, and start work on minimum performance standards.

        Can AI help to resolve the issue?

        Experts say it’s important to look at both sides of the coin, pointing to ways in which AI can contribute to more effective power grid management and integration of renewables into national power supplies.

        According to new analysis by energy think-tank Ember, AI applications such as short-term renewables forecasting, predictive maintenance, and real-time monitoring and adjustment of transmission line capacity can deliver operational improvements in power systems.

        It estimates that AI could enable Southeast Asian nations, for example, to reduce their power sector costs by $45 billion-$67 billion through to 2035, depending on how much renewable energy they deploy. Potential AI-driven efficiency gains could cut emissions by 290 million to 386 million tonnes of CO2 over the next decade in ASEAN countries, it adds.

        “While power-hungry AI might initially stress the power systems, with various powerful applications it has the potential to significantly accelerate the energy transition and offset consumed energy rapidly,” Ember data analyst Lam Pham said in a statement.

        New Investigation Reveals Forced Labour Tied to Tuna Sold in Australia

        Published

        on

        A new investigative report released by Greenpeace Southeast Asia, in collaboration with the Uniting Church in Australia, Synod of Victoria and Tasmania, has uncovered disturbing links between suspected forced labour in the Indonesian tuna fishing industry and seafood sold in Australia.

        The investigation analysed testimonies from 25 fishers working on 17 Indonesian tuna fishing vessels that supply the Australian market. These vessels supply five Indonesian processing companies, which in turn export to 18 Australian seafood companies, including major brands seen on our supermarket shelves.

        The findings raise urgent questions about human rights protections at sea and the integrity of seafood supply chains reaching Australian supermarket shelves.

        What the Investigation Found

        Fishers interviewed described experiencing multiple internationally recognised indicators of forced labour.

        Of the 11 forced labour indicators identified by the International Labour Organisation, the most frequently reported were:

        • Abuse of vulnerability (56%)
        • Debt bondage (56%)
        • Deception (40%)

        The report reveals a multi-layered recruitment network in Indonesia that channels vulnerable workers from rural areas into exploitative situations. Labour brokers, known locally as calo, collaborate with vessel administrators and manage recruitment. Fishers reported being lured with promises of high salaries and advance loans, only to be charged illegal and inflated fees for travel, training and documentation.

        The investigation also found that labour exploitation at sea is intertwined with environmental crime. Companies allegedly pushed vessels and fishers to engage in illegal, unreported and unregulated fishing practices, including shark finning and the deployment of illegal fish aggregating devices.

        The link between labour abuse and environmental destruction is not accidental. It reflects an extractive system that externalises both human and ecological costs to sustain profit margins.

        Industrial fishing not only exploits vulnerable workers and undermines human rights, it also strips life from our oceans, degrading fragile ecosystems and pushing marine wildlife toward collapse.

        What Needs to Happen Now

        The report calls for urgent action from both governments and industry.

        The Indonesian Government must:

        • Enforce decent and effective work at sea policies aligned with international standards.
        • Ensure ethical recruitment practices.
        • Guarantee fair wages and protections for Indonesian fishers.

        The Australian Government must:

        • Prohibit seafood products linked to labour exploitation and forced labour from entering Australian markets.

        Seafood companies in both countries must:

        • Conduct robust human rights and environmental due diligence across their supply chains.

        These are not abstract policy fixes. They are necessary steps to prevent modern slavery at sea and to stop environmental crime from being embedded in global seafood trade.

        Environmental Justice and Ocean Protection Go Hand in Hand

        This investigation highlights something fundamental. Human rights and ocean protection are inseparable.

        Environmental justice means the fair treatment and meaningful involvement of everyone in creating a healthy environment. When workers are exploited and forced into dangerous conditions, environmental laws are often ignored too. Abuse at sea and ocean destruction are two sides of the same industrial system.

        Destructive industrial fishing methods such as longlining and bottom trawling continue to pillage and industrialise the ocean. They kill wildlife, destroy fragile habitats and undermine the resilience of marine ecosystems.

        If we want a thriving ocean, we must protect both the people who work on them and the ecosystems themselves.

        Why This Matters for Australia and the Global Ocean Treaty

        The Australian Government is on the cusp of ratifying the Global Ocean Treaty, the legal instrument allowing governments to create high seas ocean sanctuaries free from industrial fishing. Once Australia has ratified, it has the critical tool it needs to protect the ocean and safeguard beautiful and endangered species like whales, dolphins and sharks from destructive fishing methods in the high seas.

        Vast, robust ocean sanctuaries are a crucial solution to the ocean crisis. These high seas sanctuaries will provide a blue haven where wildlife can rest, recover and thrive. Greenpeace Australia Pacific is calling on the Australian government to champion multiple high sea ocean sanctuaries in our region, starting with a first generation ocean sanctuary in the South Tasman Sea between Australia and Aotearoa, free from industrial fishing, whaling and the threat of deep sea mining.

        As this investigation shows, the stakes are not only environmental, they are deeply human.

        Australia has an opportunity to lead by cleaning up seafood supply chains at home and by championing ambitious ocean protection globally by creating fully protected ocean sanctuaries. Protecting workers’ rights and protecting ocean wildlife must happen together.
