This week
EU passes nature law
NATURE LAW: On Tuesday, the European parliament approved its “flagship” law to restore nature, reported Reuters, despite a backlash “ignited” by protests from farmers across Europe in recent weeks. The long-awaited “nature restoration” law commits countries to restoring nature on a fifth of their land and sea by 2030, the newswire said, and it includes specific targets such as restoring peatlands “so they can absorb CO2 emissions”. Carbon Brief published a Q&A unpacking the law and the challenges it has faced.
‘POPULISM AND FEAR-MONGERING’: The vote was subject to a “last-ditch attempt from rightwing parties” that “threatened to sink the deal”, reported the Guardian. The law – which now needs final approval from the EU council – was adopted with 329 votes in favour, 275 against and 24 abstentions, reported Deutsche Welle.
‘MANURE, BURNING TYRES AND TEARGAS’: The vote came amid a backdrop of continuing demonstrations by farmers across Europe, protesting against “the EU’s green policies, price pressures and import competition”, reported Politico. On Monday, farmers “locked down” the European quarter in Brussels and were “assaulting police barricades”, the outlet said. Elsewhere, Reuters reported that farmers “blocked a border crossing between Poland and Germany”.
UN environment assembly resolutions
TRANSITIONAL METALS: At the UN environment assembly in Nairobi, which comes to a close today, African leaders called for better controls on demands for the minerals and metals needed for a clean energy transition, the Guardian reported. A resolution supported by mainly African countries including Senegal, Burkina Faso, Cameroon and Chad would “promote equitable benefit-sharing” and attempt to avoid the “injustices” associated with fossil fuel extraction, the outlet explained. A UN press release confirmed that the resolution text was adopted.
SRM NO-GO: Also at the meeting, governments failed to agree on a resolution led by Switzerland to set up a UN expert panel on solar geoengineering, reported Climate Home News. After going through six revisions over the two-week meeting, the resolution was withdrawn on Thursday, said Reuters. The Earth Negotiations Bulletin reported earlier in the week that the resolution “was moving from the realm of the achievable”.
‘BALANCE’ WITH NATURE: At an event during the assembly, leading Islamic scholars published a “groundbreaking” document described as a “Muslim sibling” to Pope Francis’ 2015 Papal Encyclical, reported EarthBeat. The text, titled “Al-Mizan: a covenant for the Earth”, urges Islamic countries and corporations “to transition swiftly from fossil fuels” toward renewable energy in response to climate change, the outlet said.
Around the world
- WINTER WORRY: A “historic” winter heatwave across the central US “demolished” temperature records and contributed to “massive wildfires” in Texas, the Washington Post reported. One of the fires is now the second-largest wildfire in US history, noted BBC News.
- ‘SERIOUS CONCERNS’: The UK’s aid spending watchdog has warned that the government will struggle to meet its commitment to spend £11.6bn over five years up to 2025-26 helping poorer countries deal with climate change, according to the Press Association.
- INDIAN INSTALLATIONS: India’s solar and wind deployment is set to increase by more than 30% in 2024, reported Bloomberg, but this pace is “still not fast enough to meet its clean energy goal of 500 gigawatts by the end of this decade”.
- US ENERGY ACCESS: The US government announced a $366m plan to fund 17 projects to expand access to renewable energy on Native American reservations and in other rural areas, said the Associated Press.
- ‘SUSPECTED SABOTAGE’: Denmark is closing its inquiry into the blasts that “tore apart” two Nord Stream gas pipelines in the Baltic Sea in 2022, BBC News reported. The investigation concluded that the pipelines had been “sabotaged”, but there was “no basis for pursuing a criminal case”.
40,000 tonnes
The amount of wood from old-growth forests in Canada burned by North Yorkshire’s Drax power station in 2023, according to a BBC News Panorama investigation. Drax responded by denying it takes wood from primary forests.
Latest climate research
- A four-year farm trial has shown how using “enhanced weathering” in the corn belt of the US could draw down carbon dioxide and raise crop yields, reported a study in the Proceedings of the National Academy of Sciences.
- A Plos Climate study of apes across 363 sites in Africa warned that they “are and will be increasingly exposed to climate change impacts”.
- A Journal of Climate study identified a “remarkable” increase over six decades in Europe’s summer wet-bulb temperature – a “useful indicator” for heat stress.

Captured

This week, the Climate Change Committee (CCC) – the UK’s official advisor – issued “unequivocal” advice to the government that the “surplus” from previous carbon budgets should not be carried forward, reported Carbon Brief. The UK overachieved on its carbon budget for 2018-22, leaving it with an emissions “surplus” – but this was largely down to external factors such as the Covid-19 pandemic rather than policies, the CCC said. It warned that carrying the emissions surplus over could allow the UK’s emissions to rise by 15% (red line on the chart) during the fourth carbon budget period of 2023-27.

Guest post: The climate ‘memory loss’ of melting glaciers

Dr Andrea Spolaor from the Institute of Polar Sciences of the National Research Council of Italy, explains how rapidly melting glaciers are washing away crucial evidence of the world’s past climates.
Ice cores, extracted from glaciers and polar ice sheets, hold vital clues to Earth’s climate history.
These cylindrical samples provide a timeline of past temperatures and ancient atmospheres. Analysing the chemical composition, gas concentrations and other markers within the ice layers enables scientists to uncover how Earth and its climate has changed over millions of years.
As a result, ice cores are essential for understanding natural climate variability and human-induced changes, as well as helping predict future trends. They contribute crucial data to climate models and efforts to address climate change.
However, as the world warms, glaciers are retreating at an unprecedented pace, leading to the loss of the crucial information they hold.
In a recent study, published in the Cryosphere, my colleagues and I found that this memory loss extends to the glaciers of the Svalbard archipelago, located in the Arctic Circle.
Our study investigated the impact of rising temperatures on the “signal” of a changing climate contained within the glaciers of the Holtedahlfonna ice field.
The direct consequence of warming has been an increase in summer melt and more meltwater percolating through the ice. This meltwater can wash chemical constituents throughout the layers of ice, potentially disrupting the climate signal they preserve. Eventually, this can compromise the complete preservation of climatic information within the ice cores.
Our study revealed a worrying trend – the climate signal stored in the ice had deteriorated. In just seven years, the markers that allowed us to separate out the different seasons in a core extracted in 2012 had completely vanished in a core from 2019.
Despite the loss of the seasonal signal, the overall imprint of atmospheric warming still persists in the ice. This suggests that the site remains suitable for reconstructing past climates over an extended period. However, with the current pace of warming in the Svalbard archipelago, Holtedahlfonna and other ice fields at similar altitudes may not provide reliable records of past climatic conditions for much longer.
The Svalbard archipelago is particularly sensitive to climate changes due to the relatively low altitude of its main ice caps and the rapid warming of the Arctic region. Nonetheless, similar losses have also been observed in other parts of the world.
To preserve these archives, researchers involved in the Ice Memory and Sentinel projects concluded a complex ice drilling campaign in 2023 on the Holthedalfonna glacier, successfully extracting three deep ice cores. We hope that these samples still contain climatic information representative of the region.
Our research has emphasised the need to preserve these glacial archives and the crucial climatic insights they contain.

As blue economy gathers pace, communities must benefit from ocean boom, activists say
As governments and institutions pledged billions for offshore wind, cleaner shipping and marine protection at last month’s Our Ocean Conference in Mombasa, countries are increasingly turning to the ocean as a source of jobs and climate action.
But civil society groups warn that the push to expand the “blue economy” may reproduce familiar inequalities unless coastal communities have a greater say in how projects are designed, financed and governed.
Neville van Rooy from The Green Connection in South Africa, which works with coastal communities who rely directly on the ocean for their livelihoods, said local people were frequently unaware of proposed developments until civil society groups alerted them.
“Communities need to be taken seriously,” van Rooy told delegates at the Mombasa conference held on the shores of the Indian Ocean.
“Just because they are often struggling does not mean they do not have a vision of development. Inclusivity needs to be at the centre and development pathways must build on communities’ own experience, including indigenous knowledge systems rooted in harmony with nature.”
Ocean investment flowing in
The value of the blue economy—the sustainable use and protection of marine resources—doubled from $1.3 trillion in 1995 to $2.6 trillion in 2020 and is projected to quadruple by 2050, according to the Organisation for Economic Co-operation and Development (OECD).
The scale of ambition in Mombasa was clear, with governments, institutions, companies and civil society groups announcing 320 commitments worth $6.4 billion.
The largest share went to sustainable blue economy projects, with 86 commitments worth $2.86 billion, followed by sustainable fisheries with $1.75 billion and ocean-climate action with $1.18 billion.
The pledges included support for ocean startups in Africa, coastal ecosystem restoration across the Indian Ocean, marine research and policy, recycling discarded fishing nets, sustainable livelihoods in Timor-Leste and planning tools for offshore wind.
Cynthia Barzuna, global deputy director of the Ocean Program at the World Resources Institute, said there are signs that blue finance and ocean planning are moving closer to coastal communities, particularly through the development of sustainable ocean plans.
In 2020, a group of 14 countries – co-led by Australia and Chile – pledged to manage their oceans sustainably, by jointly drawing up plans with coastal communities to shape how marine resources are managed and where investments should go.
“Once communities are involved in the planning, bring in their knowledge, and participate in designing, developing and implementing a sustainable ocean plan, it puts us on the right path,” Barzuna told Climate Home News on the sidelines of the conference.
Yet some of those countries – including Kenya, Australia and Mexico – have embarked on a new wave of offshore oil and gas projects, threatening key biodiversity hotspots, according to a recent report by a group of environmental NGOs.
When projects go wrong
Civil society groups say lessons need to be learnt from failed blue economy projects too.
In Kenya, a proposed coal-fired power plant at Lamu Port – a fragile coastal ecosystem and a UNESCO World Heritage site – was challenged by residents and campaigners who cited little consultation and threats to fishing, tourism, culture and public health.
In 2019, Kenya’s National Environment Tribunal revoked its environmental licence, citing inadequate public participation and flaws in the environmental assessment – a decision later upheld by the courts.
“It is not enough to say that whatever you are doing is in the name of the communities, their livelihoods and whatever else you want to improve”, but that they should be directly involved in projects from the start, said Omar Elmawi, a Kenyan climate activist and Convenor of the Africa Movement of Movements.
He said another lesson learnt was that environmental impact assessments must not only be completed, but “must be done rigorously” and that the process has to be transparent so that people feel involved and that their views are being counted.
Blue transition
Blue carbon schemes can also attract finance, but campaigners said communities that have long protected mangroves, seagrasses and salt marshes must be treated as rights-holders, not just beneficiaries. In some past projects, they said, communities were asked to provide labour, attend consultations or receive small payments, while outside developers retained control over carbon revenues and decisions over how ecosystems were managed.
Similarly, offshore wind and marine protected areas can bring climate and conservation gains, but if poorly planned, they can disrupt fishing grounds, marine species and small-scale fishers’ access to the sea, added campaigners.
Farida Aliwa, executive director of Natural Justice, said the answer was not to halt ocean-based development, but to put in place stronger safeguards before projects are approved, financed and expanded.
Aliwa said legal frameworks across Africa were evolving, with strategic litigation increasingly being used to hold governments accountable for environmental, climate and human rights impacts related to new projects.
But she warned that communities and coastal defenders still face shrinking civic space, and said any shift to renewable energy must be designed responsibly.
“As we work on alternatives, we need to ensure that renewable projects benefit communities,” she said.

AI governance debate silent on risks to nature, campaigners warn
As countries gathered in Geneva this week for the first UN dialogue on the governance of artificial intelligence, campaigners said the debate around the fast-evolving technology has overlooked the potential harm it could cause to nature and biodiversity.
Not only has nature been absent from discussions on the environmental impacts of AI data centres, which focus mainly on carbon emissions and water use, there has also been no consideration of how AI deployment by industry could gobble up more natural resources, activists warned.
Brian O’Donnell, director of the Campaign for Nature, said that while AI can help protect wildlife and forests, the broader boost it will give to economic growth poses a far bigger threat than expected benefits.
“We’ve seen over $250 billion of private capital go into AI in 2024 alone – and almost all of that is seeking an economic return, and the money follows commercial value,” he told journalists. “Extraction, industrial farming, resource logistics, and the engines that drive ever more consumption are all activities that contribute to biodiversity loss.”
The leading conservationist added that the policy documents produced by leading AI companies do not address the downstream effects of their technology for nature and biodiversity, focusing more on employment and other social issues.
Some have firms have put small sums towards projects that support conservation, he noted, but none are addressing the issue in a serious way or have included nature in the safety rules for their models.
“The living world that all of this rests upon – nature being the foundation of our economies, our societies, all life on earth – is not a primary concern in the governance of AI, as proposed by the corporates of AI,” O’Donnell said.
Positive uses steal the show
Last month, UN chief António Guterres launched an initiative to hold major AI firms accountable for their exploding environmental impacts, including carbon emissions, the amount of water and land used for data centres, and the energy they consume.
The UN boss also wants big players to commit to power all data centres with renewable energy by 2030. On Monday in Geneva, in a wide-ranging speech, he again raised his proposed “AI Environmental Transparency Initiative”. But nature has not featured in his comments on the issue.
In addition, the preliminary report of the newly formed Independent International Scientific Panel on AI – which assesses the opportunities, risks and impacts of AI – mentions environmental concerns only briefly.
The report, which examines available scientific evidence and was presented to governments at the Geneva dialogue, does not highlight any threats to nature and biodiversity but cites a study showing how AI has been used to track and reduce conflict between humans and wildlife.
O’Donnell pointed to “some really important technological uses of AI for biodiversity” such as monitoring species, forest damage and tree cover and using camera traps to see what kind of wildlife migrates in a particular area. But, he added, these get a disproportionate amount of attention compared with the threat from more rapacious resource extraction which he perceives as far greater.
By making commercial operations cheaper, quicker and more efficient, and opening access to untapped areas of land and sea, AI could drive biodiversity loss through increased over-exploitation of fish, wildlife and timber, worsening pollution and spreading invasive species on faster trade networks, he added.
Indigenous concerns
Indigenous peoples are also worried that their lands, critical mineral reserves and knowledge will be appropriated by AI and the accelerated economic development it fuels, said Hindou Oumarou Ibrahim, a leading global environmental activist and Indigenous leader from Chad.
Ibrahim, who produced a report on Indigenous peoples and AI for the UN in April, told journalists that before Indigenous peoples share their know-how on managing forests and stewarding nature, companies and governments must put in place principles to ensure this can happen in a fair way that prevents it being abused by bad actors.
Warning against ‘consumer club’ as G7 forms critical minerals alliance
Her report also points to positive ways that AI can support Indigenous culture and rights, such as tackling their lack of access to digital tools, preserving their languages and knowledge and mapping their territories to detect threats and better protect biodiversity.
Efforts such as those by the UN to shape the future of AI governance should look not only at what AI can do, but also ask who benefits and how it safeguards the planet, Ibrahim said.
“If we answer those questions together with Indigenous peoples as equal partners, we can build AI that serves humanity, protects biodiversity and help restore the balance between peoples and planet in an equitable and just way,” she added.
Policy processes lag AI development
Both O’Donnell and Ibrahim said they would lobby countries, the UN and AI firms themselves to put nature and biodiversity on the political agenda, including at the UN biodiversity summit in Armenia in October.
O’Donnell told Climate Home News that when the Global Biodiversity Framework, the world’s main treaty to protect nature, was agreed in 2022, AI was still nascent but has since exploded in terms of investment and its influence on economies.
The vote that stopped a data center: US communities query resource-hungry AI
He pointed to the mismatch between the timeline of the UN’s efforts to develop governance guidelines and the speed with which AI is being developed in the real world.
“Nature can’t be sidelined in these discussions,” he said, calling for a faster and more comprehensive response from policymakers, business and the environmental community.
“We have a very short window to embed nature both into the governance constitutions of the companies themselves and into the formal regulatory [system] going forward,” he added.

Ugandan farmers launch UK court case against East African oil pipeline
Four Ugandan farmers filed a case with London’s High Court on Tuesday, aiming to stop the East African Crude Oil Pipeline (EACOP) from starting to operate by asking the court to apply Uganda’s laws against the project’s UK-registered company.
The controversial 1,443-kilometre (897-mile) pipeline, majority-owned by French energy company TotalEnergies, aims to carry crude from Ugandan fields for export through neighbouring Tanzania. About 80% has been built so far, according to its developers.
The pipeline’s first oil exports are expected as soon as October, according to its developers, and the campaign group Avaaz, which is backing the farmers’ crowdfunded lawsuit, called it “one final chance to stop one of the worst oil pipelines on the planet”.
The claim, filed by London law firm Leigh Day, argues that EACOP Ltd’s role in developing and operating the pipeline breaches Ugandan laws that protect citizens’ right to a clean and healthy environment.
One of the claimants, Racheal Tugume, told a press conference she had been displaced from her land due to the pipeline’s construction, which she said had damaged local rivers, wildlife and ecosystems that communities depend on for their livelihoods just as erratic weather linked to climate change takes an increasing toll.
“I am very happy that there are people in countries like the UK who are listening to us, who are behind us and who have come to support us,” Tugume said, adding that she hoped the case would bring justice to communities affected by the pipeline.
Ugandan law in UK court
While the pipeline is a joint venture led by TotalEnergies, with smaller stakes owned by Ugandan, Tanzanian and Chinese national oil firms, it is operated by EACOP Ltd, a company registered to an office in London’s Canary Wharf financial district.
EACOP Ltd did not respond to a request for comment.
The claim appears to be the first attempt to have Uganda’s climate and environmental protections enforced in a foreign court, partly reflecting concerns over whether cases challenging the multibillion-dollar pipeline would get a fair trial in Uganda.
Ugandans living near new oil pipeline let down by compensation programmes
Concerns about access to a fair hearing are among the issues the court will consider when deciding if it should take on the case, said Matthew Renshaw, partner at Leigh Day.
Renshaw said that precedents including the Nigerian oil pollution case against Shell have shown that claims against British-registered companies for harms overseas can be successfully fought in UK courts.
“We are proud to represent the four brave principled individuals,” Renshaw said.
Constitutional protections
The pipeline project has already been subject to repeated lawsuits in several countries, none of which have succeeded. A climate lawsuit filed in Uganda more than a decade ago by a group of young people has yet to conclude. Another at the East African Court of Justice, brought by campaign groups against Uganda and Tanzania, was rejected on procedural grounds last November.
A separate ongoing lawsuit in TotalEnergies’ home country of France – a refiled version of an earlier failed claim – cannot stop EACOP going ahead, but it does seek damages from TotalEnergies for affected communities.
With the newly launched case, Leigh Day’s legal adviser Marc Willers said the claim draws on specific Ugandan laws in a bid to stop EACOP’s operations.
Uganda may see lower oil revenues than expected as costs rise and demand falls
These include the Ugandan constitution, a 2019 environmental law and the National Climate Change Act 2021, which gives Ugandans the right to bring a case before a court in circumstances where anyone or any entity threatens the country’s ability to mitigate climate change.
Stopping a “carbon bomb”
The pipeline, which will link Uganda’s Lake Albert oil fields to Africa’s east coast in Tanzania, has already displaced thousands of people and cuts through the Lake Victoria basin, one of East Africa’s major freshwater systems and a critical water source for around 40 million people.
According to the BankTrack non-profit, when the pipeline is at peak production, it will carry 216,000 barrels of crude oil per day and release over 33 million tonnes of carbon emissions each year. Over its full lifetime of 25 years, it is estimated to release about 379 million tonnes of greenhouse gas emissions across its value chain including construction, refining and product use.
A May 2026 report from Earth Insight also warns that the pipeline and related infrastructure could affect 158 wetlands in Uganda, 11 rivers, 44 protected areas and seven key biodiversity areas while disrupting about 2,000 square km of protected wildlife habitats.
This is why the primary focus of the UK court case is to stop the operation of the pipeline in its tracks, Leigh Day’s Willers said, calling it a “carbon bomb” that would worsen the world’s climate crisis.
Long wait for first hearing
While the purpose of the case is to stop the pipeline from launching operations, Renshaw said it could take about 12 months before the case gets a first hearing and about 18 months before it goes to trial.
Billions unlocked as Green Climate Fund agrees to spend more and save less
The farmers are, however, seeking an injunction to stop EACOP Ltd from proceeding with operations. In the event that shipments begin, the lawsuit will still seek to stop the pipeline from then on, Renshaw said.
“We will be doing what we can to expedite matters but it is possible that EACOP will have started operating the pipeline before the claim is heard. If that is the case, the claim would intend to halt operations from that point. For example, the pipeline may operate for just one year rather than 30-plus, resulting in far less harm,” he said.
