Trump ‘SOS’

‘CHAOS’ GRIPS: More than 1,900 scientists from US national academies of sciences, engineering and medicine wrote an “SOS letter” warning of the risks to science imposed by the current administration’s grant cuts and mass layoffs, reported the Guardian. The Guardian also said a “sense of chaos has gripped” the National Oceanic and Atmospheric Administration, after Trump-sanctioned layoffs have affected 20% of staff.

WEAKER STANDARDS: Trump is weighing returning to weaker car emissions standards from 2020, saying pollution limits introduced by Joe Biden are “too onerous” for motor companies, Bloomberg reported. The US transportation sector is the country’s leading source of greenhouse gas emissions.

TARIFFS TURMOIL: The New York Times said that the renewable energy industry in the US is “bracing for particularly large effects” from Trump’s ongoing tariffs war with the rest of the world. It noted that the turmoil is “expected to drive up the costs of nearly every component of clean-energy production in the US, from the steel in wind turbines to the batteries in electric vehicles”.

Around the world

  • SOFTENING GOALS: EU Climate Commissioner Wopke Hoekstra is considering softening the bloc’s 2040 climate goal amid a “backlash” from some quarters, Politico said. A second Politico story reported that the release of the goal will be delayed while Hoekstra “struggles” to rally support. 
  • COAL STICKS: The world’s total coal-fired power “inched up” by 18.8 gigawatts in 2024, the lowest rise in two decades, with new additions in China and India continuing to offset closures elsewhere, according to Reuters coverage of a new Global Energy Monitor report.
  • ASIA HEAT: Large swathes of India will experience intense heatwaves this summer with above normal temperatures expected across much of the country, the nation’s meteorological office has warned, according to BBC News.
  • RENEWABLE AFRICA: Africa increased its renewable energy capacity by 6.7% last year, equivalent to 4.2GW, according to an International Renewable Energy Agency report covered by Energy Capital and Power. Egypt, Ethiopia and South Africa were among countries to build the most clean power.

40%

The percentage by which the “average person would become poorer” if the world warmed by 4C, according to an Environmental Research Letters study covered by the Guardian.

Captured

Annual solar panel exports from China, GW, to the global south (red) and the global north (blue).

China’s exports of solar panels to the global south have doubled in the past two years, overtaking global-north sales for the first time since 2018, according to data from the thinktank Ember explained in a new Carbon Brief guest post. Saudi Arabia and Pakistan were among the top importers of Chinese solar panels in 2024.

Deep-sea mining talks

Carbon Brief explains the outcomes of the latest deep-sea mining talks held last week in Jamaica.

The deep sea has emerged as a new mining frontier in the global race towards energy security, with countries vying to explore and exploit its reserves of metals, such as nickel, copper, cobalt and manganese.

These minerals – critical to the energy transition – are held in the deep ocean’s nodules, hydrothermal vents and crusts, but the impacts of mining these deposits are still far from being fully understood.

In 2021, the Pacific island state of Nauru triggered a legal process for countries to agree rules around mining the seabed, or – in their absence – allow commercial mining of the deep sea to begin by 2025.

The UN Convention on the Law of the Sea (UNCLOS) is an international treaty that provides a framework to regulate the use of the world’s seas and oceans.

Among other bodies and orders, UNCLOS established the International Seabed Authority (ISA), which is based in Kingston, Jamaica, and oversees all resource extraction in the deep sea.

From 17-28 March this year, the ISA held the first part of its 30th annual session, with the aim of making progress on draft rules to govern commercial deep-sea mining.

The ISA said that there was “significant progress” on various aspects at the meeting and other areas that “require further deliberation”.

Some of this progress is the agreement to use the term “harmful effects” rather than “serious harm” to the marine environment, which aligns with the UN Convention on the Law of the Sea (UNCLOS), the Earth Negotiations Bulletin noted.

However, it added that there were “major issues unresolved”, related to “regulations” crucial for the protection of the marine environment, such as environmental impact assessments and the rights and interests of coastal states.

Duncan Currie, the international legal advisor to the Deep-Sea Conservation Coalition, said parties did not agree on any of the 55 reviewed regulations, but rather just discussed their positions on those regulations.

He also pointed out the lack of discussion over financial matters, liability, the royalties that are paid and the benefit sharing from deep-sea mining, telling Carbon Brief:

“There are 80 standards and guidelines that can’t be developed until [countries] have developed the regulations. I think most people think that they’re quite a long way away from being adopted.”

Current and future outlook

So far, 32 ISA member states are in favour of a moratorium on deep-sea mining, while other countries are seeking to exploit minerals in the seafloor “as soon as possible”.

Among those promoting the deep-sea mining industry are India, China and Norway, while countries such as Palau, Fiji and Samoa are promoting a “pause on deep-sea mining until its ecological impacts are better understood”, Carbon Brief previously reported.

In a surprise move that sent “alarm bells ringing” in the ISA and beyond, the US subsidiary of the Metals Company announced on 27 March that it is moving ahead with applying for deep-sea exploration permits under existing US legislation in the second quarter of 2025.

The announcement came on the last day of the ISA talks, where it dominated discussions at the end of the meeting.

On 31 March, Reuters reported that the Trump administration is “weighing an executive order” that could let miners bypass the ISA, its safeguards and “fast-track” permits. The US is not a party to UNCLOS.

Both developments signal that the ISA is “at a crossroads”, according to the Earth News Bulletin, and its next session in July will be closely watched for how the body responds to a potential unilateral action to allow deep sea-mining.

“We’ve gone backwards” – new plastics treaty text dims hopes for production curbs

Published

on

A new draft text to revive deadlocked UN plastics treaty talks does not include specific measures on managing runaway plastic production, a growing source of greenhouse gas emissions, drawing criticism from some countries and campaigners that ambition for the global pact is shrinking.

After diplomats met in Nairobi early in July for the first time since negotiations fell apart a year ago, Chilean ambassador Julio Cordano, who is chairing the talks, released a first document last weekend, setting out elements of a possible treaty to tackle plastic pollution.

Cordano stressed this is an “informal reference document” rather than a negotiated text. But its structure is similar to a draft treaty and closely resembles the previous version rejected by governments during the last round of formal negotiations in Geneva.

The new text recognises the world’s “unsustainable” levels of plastic production and consumption, both of which are projected to nearly triple by 2060. But it contains no measures to stem that growth, critics say, pointing to what they see as a broader weakening of ambition.

They argue the document is increasingly aligned with the demands of fossil fuel-producing countries, including Gulf states, the US and Russia, which have pushed for the treaty to focus on managing plastic waste rather than limiting production.

“When you leave the countries that have the most vested interests in delaying meaningful action to shape the agenda, you end up with a text that does nothing to end plastic pollution,” said David Azoulay, environmental health programme director at the Center for International Environmental Law (CIEL).

France disappointed with production omission

“We’ve gone backwards rather than forwards,” Christina Dixon, a campaigner at the Environmental Investigation Agency (EIA), told Climate Home News. “A text that was rejected by the majority of countries in Geneva as being too weak and not ambitious enough has been repackaged one year later with some key elements removed and put out as a kind of sign of progress.”

A French diplomatic source told Climate Home News it was “disappointing” that the text lacked any concrete provisions on tackling “unsustainable” levels of plastics production and consumption. That is despite a majority of countries repeatedly advocating for curbs and scientists saying the world cannot put an end to plastic pollution without tackling the issue at source, they added.

    Governments across Europe, Latin America, Africa and the Pacific islands have previously called for efforts to limit the manufacturing of plastics to “sustainable levels”, but their efforts have been frustrated by strong and persistent opposition from a small group of fossil fuel producers, who see plastics as a growing market for oil and gas.

    Weakening of production ambition

    Cordano told Climate Home News that the “concept” of sustainable production is still reflected in different parts of the new document.

    But measures aimed at achieving that objective have progressively weakened over time. Initial versions of the draft treaty, dating back to 2024, included a standalone article with the option of setting a global target to reduce the production and consumption of primary plastics.

    That disappeared from successive drafts published in Geneva last year. The last version nevertheless said data on plastic production could be considered in future assessments of whether the treaty was meeting its objectives. Observers saw this as an important provision that could have strengthened the pact over time and potentially kept the door open for a global production target.

    The new text only mentions “sustainable production” in the preamble and includes an article saying that countries could improve the design of plastic products in order to contribute to “sustainable production”.

    “There’s a war of attrition element,” said Dennis Clare, a negotiator for the Pacific island nation of Micronesia. “The countries that want to do less are dragging out discussions and gradually pressuring the more ambitious to compromise towards a lower common denominator.”

    Little space for thorny discussions

    Countries have twice failed to agree on a global plastics treaty at what were meant to be final rounds of negotiations in December 2024 and August 2025. After being selected as the new chair earlier this year, Cordano has been working to steer the process back on track through a series of informal meetings, hoping diplomats can find common ground ahead of the next formal negotiations scheduled for early 2027.

    But he has been criticised for sidelining discussions on some of the thorniest issues. Cordano kept plastic production off the official agenda for the Nairobi meeting a few weeks ago. He said beforehand that countries could bring any issue to the table, but production did not feature in the summary of discussions subsequently published by the chair.

    Clare said discussions on fundamental elements of the treaty, including production, had been “constrained” and that there was little space for them in Nairobi.

    Cordano told Climate Home News the Nairobi talks had provided space both for “reaffirming positions and expressing new ideas”, adding that countries “remain free to raise all issues they consider important”.

    Informal talks between negotiators are held behind closed doors and neither the media nor external observers can take part.

    Campaigners have accused the chair of making political calculations to reach an agreement at any cost. “He has clearly identified that the only way to achieve an agreement by consensus is to do away with the more complex elements of the treaty like those that deal with sustainable production and consumption of plastics,” the EIA’s Dixon said.

    Cordano said he continues to be guided by countries as “they develop their own exchanges and continue working towards possible landing zones”.

    Push for more ambition

    Governments will debate the new text at another meeting of chief negotiators in Bangkok, Thailand, at the end of September, and a new version of the document is expected after that meeting.

    The French diplomatic source said the current text should not be viewed as “an end-product”, but as a starting point that “can and should be improved”.

    France, together with the EU and members of the High Ambition Coalition (HAC), will continue pushing for stronger provisions, including measures to address plastic production, the source said.

    China’s coal power rebounds as record clean energy goes to waste

    The HAC group includes over 70 countries, primarily from across Europe, Latin America, Africa and the Pacific.

    Micronesian negotiator Clare said countries on the frontline of the plastics crisis may decide to reject a really weak treaty that puts the burden on them to clean up somebody else’s waste, while producers can keep churning out plastics unrestrained.

    “If the treaty does not include essential elements of the solution, even an initial, apparent diplomatic success – an agreement – can come to be seen over time as an environmental failure,” Clare warned.

    South Africa’s offshore oil push meets grassroots resistance in court

    Published

    on

    Layers of red dust coat South Africa’s Saldanha Bay, a legacy of the one billion-plus tonnes of iron ore exported from what was once a quiet coastal fishing town in the 1970s. Now the government wants to turn this area into the “oil and gas hub of South Africa”, but opposition from local communities and civil society could force a change of plan.

    Since 2014 South Africa has developed a strategy for taking “full advantage” of its marine resources, known as Operation Phakisa. It has resulted in the mapping of more than 95% of the country’s nearly 3,000-kilometre coastline for offshore oil and gas exploration.

    The plan seeks to “drill 30 exploration wells in 10 years”, which it estimates could lead to the production of an average of 370,000 barrels of oil and gas per day over 20 years, with Saldanha Bay earmarked as a key logistics hub. It also aims to develop other marine sectors like aquaculture, maritime transport and ocean tourism.

    However, two major court cases against the government and oil giants Shell and TotalEnergies have challenged those plans, as coastal residents, allied with national civil society groups, have pushed back against oil concessions held by the multinationals, arguing they were not consulted, and that towns like Saldanha Bay could face social and environmental harms from the fossil fuel extraction.

      Melissa Groenink-Groves, programme manager at legal nonprofit Natural Justice, said the cases in South Africa could set a precedent for the whole region. “When communities win in the courts, the successes serve as inspiration for other communities to advocate [for] their rights in their own contexts,” she explained.

      She added that the legal challenges to Operation Phakisa also develop climate litigation in the African context, and could impact how environmental impact assessments are conducted going forward.

      Globally, as the oil and gas industry sets its sights on the ocean, with over 85% of new discoveries in 2024 made offshore, scientists and activists warn it could threaten marine life and coastal communities, and weaken the ocean’s ability to trap excess heat from the atmosphere, fuelling planetary warming further.

      Taking oil companies to court

      About 300 kilometres north of Saldanha Bay, the Aukotowa Fisheries Cooperative, backed by nonprofits The Green Connection and Natural Justice, has taken TotalEnergies to court over its plans to drill for oil and gas in a 30,000-square-kilometre block off South Africa’s west coast.

      The oil exploration block is in a biodiverse marine area bordering Namibia and South Africa known as the Orange Basin, which is a “highly relevant” sanctuary for endangered species, according to Nelson Mandela University’s Institute for Coastal and Marine Research.

      Among other grievances, the cooperative maintains that the company’s environmental impact assessment was flawed, failing to consider the project’s contribution to climate change, and that the government “placed the profits of a multinational corporation above the livelihoods of vulnerable coastal communities”. The Western Cape High Court concluded hearings in late March and is expected to deliver a ruling later this year.

      Walter Steenkamp, chairperson of the Aukotowa Cooperative, is concerned that the oil and gas drilling will lead to increased inequality, asking “for whom is the development? Definitely not for us.”

      In a written statement, TotalEnergies told Climate Home News that it “is a responsible operator fully committed to complying with all applicable South African legislation”.

      Communities and climate impacts at stake

      On the other side of the country, along South Africa’s eastern coastline, community-based nonprofit Sustaining the Wild Coast and partner organisations challenged Shell and Impact Africa’s exploration permit, arguing that the firms had failed to consult impacted communities – a legal requirement under South African law.

      Co-plaintiff Sinegugu Zukulu also said in 2022 that “oil and gas will lead to more emissions, and in the face of climate change, this is wholly irresponsible”.

      Following two rulings against the companies by lower courts, the case is now before South Africa’s highest Constitutional Court, which has reserved judgment since September 2025. A ruling against the companies would be final, effectively ending the exploration permit.

      Legal expert Groenink-Groves said oil exploration applications under Operation Phakisa have been “granted largely without properly assessing the devastating impact an oil spill could have on small-scale fishers, the risks of drilling in ultra-deep waters, [and] without accounting for climate change impacts associated with oil and gas exploitation”.

      She added that exploration applications have often failed to consider coastal management laws and in some cases, cross-border and regional environmental risks.

      Shell and South Africa’s Department of Mineral and Petroleum Resources did not respond to written requests for comment.

      South Africa’s offshore oil ambitions

      Fishers around South Africa, many of whom have for generations relied on marine resources for survival, say the country’s offshore oil and gas push is sacrificing their livelihoods for profit.

      “Why do they want to destroy our heritage? We can’t afford to say yes to oil and gas because the ocean is our source of life,” said Carmelita Mostert, a member of advocacy group Coastal Links and third-generation Saldanha Bay fisher.

      Yet with unemployment above 30%, alongside high levels of poverty and wealth inequality, the government sees Operation Phakisa as a vehicle for socioeconomic development.

      South Africa’s Minister of Mineral and Petroleum Resources Gwede Mantashe has described the court cases as “anti-development”, and claimed that the environmental organisations are funded by the CIA.

      Sifiso Dladla, a campaigner with human rights organisation groundWork, argued that the close relationship between the government and the fossil fuel industry – including its 3% contribution to gross tax revenue – limits the potential success of movements pushing for an inclusive energy system. Politicians “need money to win elections. Mining companies need the government to protect them,” he said.

      Patrick Bond, a political economist and sociology professor at the University of Johannesburg, said Operation Phakisa only makes economic sense if its social and environmental harms are ignored, adding that “if a genuine social cost of carbon analysis were done in any African fossil fuel project, there would be few – if any – able to justify the projects economically”. 

      At a global scale, Bond said oil multinationals have the financial backing of European governments – including France’s $2.8 billion stake in TotalEnergies – which can help make local resistance more effective where it has international allies to amplify the messages.

      For Saldanha Bay fisher Mostert, the fight is about protecting the livelihoods of coastal communities. “It is my hope that we can stand strong and protest,” she said. “If oil and gas is not allowed, our lives will be much easier and better – but if oil and gas goes ahead we will be in absolute agony.”

      Millions of kilograms of marine life taken from Australia’s marine protected areas every year, FOI finds

      Published

      on

      SYDNEY, Tuesday 11 August 2026 — New data obtained by Greenpeace Australia Pacific has found millions of kilograms of marine life are being taken from Australian marine parks by commercial fishers annually, as the government begins its review of the country’s Marine Parks Network.

      The data, released to Greenpeace in response to a Freedom of Information request, relates to 18 of Australia’s 60 Commonwealth marine parks, and shows almost 2.2 million kg of marine life is being fished each year, raising concerns about the true catch numbers across all marine protected areas.

      Greenpeace is calling for the Labor government to use the once-in-a-decade Marine Parks Network review, announced last fortnight, to ban industrial activities, including bottom trawling, longlining and oil and gas mining, from Australia’s Marine Parks Network, and increase fully-protected ocean sanctuaries within the network.

      Elle Lawless, Senior Campaigner at Greenpeace Australia Pacific, said:

      “It’s chilling to think of the true scale of destruction happening inside all of Australia’s marine parks, and how much of our precious ocean wildlife, like dolphins, turtles or seabirds, could be pulled out of protected areas as bycatch.

      “We’re talking about 6,600 kilograms of wildlife in one day, and that does not include what’s caught in the other 42 marine parks, many of which allow destructive fishing like longlining.

      “Australia has made significant progress in securing 52% of its oceans in marine parks; however, this intent is undermined by zones that allow damaging industrial fishing activities, such as bottom trawling and longlining. The review of Australia’s Marine Parks Network is a critical opportunity to fix what isn’t working and finally give our oceans the real protection they deserve.

      You wouldn’t expect someone to bulldoze a national park on land, so why should they be allowed to trawl in a marine park?”

      “Greenpeace Australia Pacific welcomes the Albanese Government’s review of the Commonwealth Marine Parks Network as a rare opportunity to strengthen our marine parks and ban industrial fishing in Australia’s marine protected areas.”

      The documents reveal that the south-west network has the largest catch volume, at 887,160kg per year, followed by the Coral Sea network, which extends out from the Great Barrier Reef, losing significant wildlife at 808,840kg annually.

      —ENDS—

      Notes:

      • More than half of Australia’s Marine Parks Network allow extractive industries, including industrial fishing and oil and gas mining.
      • The data, supplied by the Department of Agriculture, Fisheries and Forestry, does not specify how much of the catch is fish or bycatch, like non-target fish, turtles or seabirds, and is available on request.
