Snapshot

At the UN general assembly in New York, climate change was one of the main agenda items, with the secretary general convening the first-ever “climate ambition” summit.

As part of a new week-long series, Carbon Brief examined the ins and outs of carbon-offsetting

A landmark Brazil supreme court ruling on land rights was widely hailed as a “great victory for Indigenous peoples”. 

Key developments

UN’s first-ever ‘climate ambition’ summit

‘DANGEROUS AND UNSTABLE’: As part of the UN general assembly in New York, secretary-general António Guterres convened the first-ever “climate ambition” summit, inviting 34 leaders to speak “in recognition of their strong action on climate change”, notably omitting the US, UK, China, India and COP28 hosts the United Arab Emirates, Reuters reported. At the summit, Guterres warned that society was moving “towards a dangerous and unstable world”, citing “distraught farmers watching crops carried away by floods” as one of the “horrendous effects” of unabated fossil-fuel use, according to Politico. Dennis Francis, a diplomat from Trinidad and Tobago, warned the summit of “potential catastrophe” due to sea level rise, adding that “fertile river deltas like the Mississippi, Mekong and Nile – the world’s breadbaskets – are sinking”, a UN News story said.

AMBITION AND ASSISTANCE: Brazil “brought the biggest news to the table” at the summit, Climate Home News wrote, announcing its plan to “undo former president Jair Bolsonaro’s cuts to its climate ambition and strengthen its targets further”. The country now plans to cut emissions by 48% by 2025 and 53% by 2030. Meanwhile, leaders from several island nations castigated rich countries at the general assembly, with Marshall Islands president David Kabua calling for “the establishment of an international financing facility to assist small island and low-lying atoll nations facing natural disasters”, according to a separate Reuters piece. Another event at the general assembly was the first-ever meeting of the Commonwealth environment and climate ministers. At the meeting, the ministers “noted the role of ecosystem-based approaches, ocean action, land restoration and food-systems transformations in climate resilience and sustainable development”, said a press release from the Commonwealth.

HIGH-SEAS SIGNATORIES: Also at the general assembly, 76 nations and the EU signed the high-seas treaty, “signalling interest in ratifying the agreement designed to protect marine biodiversity in international waters”, Mongabay said. The signing marks a “significant step” towards conserving the high seas, which make up around two-thirds of the world’s oceans, the outlet added. Each country must now ratify the treaty according to its own procedures; once 60 nations have done so, the treaty can finally come into force. The Pacific Islands News Association quoted Pacific Ocean commissioner Dr Filimon Manoni, who said that “to be truly paradigm-shifting, we must aim towards universal participation” in the treaty.

Carbon offsets series

NEW SERIES: Carbon Brief examined the topic of carbon-offsetting in a new week-long series of articles delving into the impact, history and controversies of offsets. As part of the series, Aruna Chandrasekhar wrote an in-depth Q&A on ‘biodiversity offsets’, which have been promoted as one of the key ways to support nature conservation and its goals. Biodiversity-offsetting “sits at the heart” of tensions between biodiversity-rich developing countries demanding more public finance and “debt forgiveness” to help them meet biodiversity targets and rich countries rolling out new “nature markets”. The piece discussed the history, concerns and use of these offsets.

ALL THINGS OFFSETS: In the main article of the series, Carbon Brief examined all aspects of carbon-offsetting. The outlet’s international team of journalists explained what offsets are, how they are used by businesses and nations and why they can be a problematic climate solution. It also explored whether the carbon-offsetting system, which one expert described as “deeply broken”, could ever be effectively reformed. This infographic further explained how offsets work by following the journey of a fictional carbon offset purchased on the voluntary market. Elsewhere, a recent report found that rainforest conservation offset projects are not suitable and a different approach should be used to safeguard critical ecosystems, according to the Guardian.

CLOSER LOOK: In a separate Carbon Brief piece, Daisy Dunne and Yanine Quiroz trawled through news stories and investigations into individual carbon-offset projects to create a detailed map showing the global scale of these initiatives. They found that 70% of the articles examined showed evidence of the projects causing harm to Indigenous peoples and local communities. Almost half of the reports found evidence of offset projects overstating their ability to reduce emissions. To round out the week of reporting, Carbon Brief is hosting a free webinar at 3pm UK time tomorrow, Thursday 28 September, where a group of expert panellists will discuss how carbon-offsetting could be reformed.

Brazil Indigenous victory

LAND RIGHTS: Brazil’s supreme court ruled against a “highly controversial time-frame proposal” that would have “stripped Indigenous rights” to land, according to Mongabay. Indigenous chief Arakuã Pataxó told the outlet: “Without a doubt this is a great victory for Indigenous peoples.” The “time-frame thesis”, if approved, would have prevented Indigenous claims to traditional lands that they had not physically occupied before 5 October 1988, when Brazil’s constitution was enacted. Brazil Reports said this would have “overlooked that during Brazil’s military dictatorship (1964-85), many Indigenous peoples were persecuted and forced from their lands”, alongside the “obvious challenges” in obtaining proof of land occupation.

TENSIONS RUN ON: The ruling will “reshape the way the state approaches Indigenous land rights in Brazil”, according to the Guardian, setting a precedent that will have “widespread implications for all land-boundary disputes in Brazil”. However, the newspaper said that the ruling will not fully solve long-standing tensions around land conflicts. Indigenous leaders told the newspaper that they remain “anxious about attacks by non-Indigenous tenants”. Farmers said they are also worried about potential conflicts as “frictions emerge when Indigenous ranchers and farmers live in the same region”, the piece noted. 
NEW DEAL: Elsewhere, the Cameroon government reached an agreement with the Indigenous Baka people to provide them with “more access to natural resources in the country’s protected forest areas”, Radio France Internationale reported. This expanded on a 2019 deal that gave Baka communities “unfettered access” to two national parks in the south-east of the country, the radio network said. The “original forest dwellers” will now have access to another national park and a wildlife reserve. The country’s minister of forestry and wildlife, Jules Doret Ndongo, said this is “another milestone moment in our efforts to promote the rights of Indigenous people and local communities in the preservation of biodiversity”.

News and views

AG EMERGENCY: Uruguay has extended its agricultural state of emergency until at least the end of the year. The declaration encompasses “livestock, dairy, horticulture, fruit, agriculture, beekeeping, poultry and forestry”, according to the South American news agency MercoPress. The initial declaration was signed on 25 October 2022 due to ongoing drought in much of the country. Uruguayan livestock minister Fernando Mattos said that the country is “on the way to normal rainfall, [but] there is still a long way to go to recover and reach the ideal point”. MercoPress added that the onset of El Niño “is likely to bring above-average rainfall”.

BURNED OUT: Canada’s record-breaking wildfire season – with more than 200 fires still burning across the country – have turned its “vast forests from carbon sink into super-emitter”, the Guardian wrote. The blazes have emitted around 2bn tonnes of CO2, or “triple the country’s annual carbon footprint”, the newspaper said. It added: “Decades of large wildfire and the mass die-off of trees from insects transformed the boreal from carbon sink to source.” Carbon Brief recently attended a US National Academies workshop on measuring greenhouse gas emissions from wildland fires, where experts noted that such emissions are “considered natural and, therefore, are not included in national greenhouse gas inventories”.

FRAUGHT FARM BILL: With the possibility of a US government shutdown looming, “it will be difficult or even impossible for Congress to enact a new farm bill”, Ag Insider wrote. The current bill expires on 30 September – the same day that the government is slated to shut down, although funding for many programmes follows a separate schedule. “There is little peril until dairy subsidies terminate on 31 December,” according to a separate Ag Insider article, which noted that December “is the new target” for the bill’s passage. The farm bill is projected to contain more than $1.5tn of spending, including on nutrition programmes, international aid, conservation work and crop subsidies.

SOMETHING IN THE WATER: The biggest freshwater lake in Ireland and Britain has hit a “crisis point” due to toxic blue-green algae, the Irish Times reported. This cyanobacteria – a type of bacteria that can photosynthesise – has made Lough Neagh “dangerous to anyone or anything that enters the water”, the newspaper added. The “underpinning drivers” of the issue, according to the Northern Ireland department of environment, include “excess nutrients from agricultural and wastewater systems” along with “climate change and the associated weather patterns, with the very warm June, followed by the wet July and August”. The Social Democratic and Labour party launched a motion to recall the devolved government in Northern Ireland, which has been at a standstill since last year, to discuss the “ecological crisis” on Lough Neagh, BBC News said.

COP28 GREENWASHING: DeSmog released a guide to the “greenwashing” terms that “the world’s largest food and farming companies will be using to sway debates” at COP28 in Dubai. Making the list are “regenerative agriculture”, which the outlet wrote “has ‘limited potential’ to mitigate climate change”; “sustainable intensification”, which is “the idea that industrial farming can continue to grow…but can do so while causing less damage”; and “nature-based solutions”, which DeSmog wrote is likely to be invoked during negotiations around the global carbon-credit market. In a separate piece, DeSmog examined the “Pathways to Dairy Net-Zero” group, a collaboration between the UN Food and Agriculture Organization and several other “international groups connected to the dairy industry” that focuses on climate change “solutions that can serve the industry”. DeSmog argued that its focus on improving “efficiency”, rather than reducing pollution, “has only enabled it to produce more milk – and with it, more emissions”.

KIWI FARMERS: “Rural voter anger” towards policies to tackle climate change and reduce emissions may bolster a “return of right-wing parties to power” during an upcoming general election in New Zealand, according to Reuters. Rural voters, who had a “flirtation” with the country’s Labour party in 2020, are looking to conservative candidates on 14 October to “unwind or delay” policies such as “planting pine forests on grazing land and taxing livestock methane burps”. Farmers have staged several protests in the past two years against these regulations, Reuters noted. Similar protests in the Netherlands saw a farmers’ party winning “sufficient support to shake up the country’s senate”, the newswire said, acquiring 16 of the 75 senate seats.

Watch, read, listen

SPROUTING: For Hawai’i Magazine, Kevin Allen wrote about the 150-year-old Lahaina Banyan Tree, which is acting as a “ray of hope” for locals devastated by last month’s Maui wildfires.

INCLUSIVE AG: In the Kathmandu Post, two researchers discussed the “multifaceted challenges” facing the agriculture sector in the mid-hills of Nepal, and how they can be addressed through gender-inclusive policies.

BIODIVERSITY CHATS: BBC Sounds podcast, the Life Scientific, spoke to Alexandre Antonelli, the director of science at the Royal Botanic Gardens, Kew, about his “life spent in the wild”.

CHARRED: A piece by Max Graham in Grist looked at whether the production of biochar – described as a “focal point” in efforts to turn agriculture into a climate solution – can be scaled up.

New science

Earthworms contribute significantly to global food production
Nature Communications 

New research found that earthworms contribute to around 6.5% of the world’s grain production. Researchers looked at maps of earthworm abundance, soil properties and crop yields alongside earthworm-yield responses to estimate the impact these invertebrates have on the global production of key crops. They found that impacts were “especially notable” in the global south – for example, earthworms contributed to 10% of overall grain production in sub-Saharan Africa. The scientists concluded that while the earthworm impact is important, they “suspect that other soil biota may be equally as important and that further study is needed”.

Intentional creation of carbon-rich dark earth soils in the Amazon
Science Advances

Ancient peoples in the Amazon used soil management practices to improve soil fertility and crop productivity, according to a new study. Researchers compared modern fertile soil called “dark earth” to that of ancient times, then used studies of present-day Indigenous practices to propose a model of how dark earth may have formed previously. They found that the “ancient and modern dark earth deposits have similar compositions and spatial distributions”, indicating that the former may have also been intentionally cultivated by Indigenous peoples of the time. The researchers wrote that the study “highlight[s] the value of Indigenous knowledge for sustainable rainforest management”.

Likely impacts of the 2022 heatwave on India’s wheat production 
Environmental Research Letters

The spring 2022 heatwave in India reduced wheat production in some regions by up to 15% compared to a normal year, a new study found. The researchers built a statistical model using weather and wheat-production data from 1967-2018 across five Indian states that together produce around 90% of the country’s wheat. The results showed that the heatwave reduced wheat yields by 4.5% on a national scale. The likelihood and intensity of heatwaves are due to continue as a result of climate change, the researchers wrote, so “timely forecasts of their impacts on agriculture are critical”.

After another battery startup bankruptcy, can Europe ever cut reliance on China?

Published

on

Just one year ago, Lars Christian Bacher said his career embodied the energy transition – moving from CFO of Norway’s state-controlled oil company Equinor to leading one of Europe’s few home-grown battery makers.

Morrow Batteries was on a mission to compete alongside the industry’s dominant Asian, mainly Chinese, battery producers as Europe sought to reduce its reliance on imports, Bacher told a group of foreign journalists on a sunny day in Oslo last May.

But seven months later, Bacher stepped down as CEO, and earlier this month, Morrow Batteries said it had filed for bankruptcy after its financial situation “deteriorated”.

Coming a year after Swedish battery maker Northvolt filed for bankruptcy, industry analysts said Morrow’s descent into financial difficulties would likely deal a fresh blow to investor confidence in European battery manufacturers – potentially keeping Europe dependent on Chinese energy transition technology for longer.

While bigger European battery makers such as ACC, Verkor and PowerCo – linked to car-makers Stellantis, Renault and Volkswagen, respectively – are still in business, Europe needs to reduce its reliance on China, experts say.

“It’s just such a critical technology that you cannot rely on somebody else,” said Julia Poliscanova, batteries lead at the Brussels-based advocacy group Transport & Environment.

State-backed eco-batteries

Established in 2020, Morrow Batteries expanded its workforce to more than 200 and has the ability to produce three million batteries a year at its factory in the forest outside the coastal city of Arendal, on Norway’s picturesque southern tip.

Investors in the startup included industrial engineering companies Siemens and ABB, and it received a 550 million krone ($59 million) loan from state development agency Innovation Norway. State-owned energy and investment companies were also among its shareholders.

Morrow has promoted its batteries as particularly sustainable, with solar and hydropower supplying energy to the factory. Its lithium iron phosphate (LFP) batteries do not contain nickel or cobalt, distancing them from the environmental and social problems often linked to critical minerals mining.

“From a sustainability point of view, this is as good as it gets,” Bacher said last May.

He did not immediately respond to a request for comment on the company’s decision to file for bankruptcy proceedings.

It aimed to sell these batteries for energy storage, increasingly important as variable solar and wind power comes to dominate European grids, and for off-road and commercial vehicles. Those sectors, rather than electric cars and motorbikes, were being targeted because they were subject to less ferocious competition from Asia, Bacher said.

Industry experts say Morrow started smaller and slower than Northvolt, was selective about its target customers and secured deals with Finnish environmental technology company Proventia Oy and an unnamed German defence company.

But it still ran into financial trouble.

Cash crunch proves costly

In a statement announcing the bankruptcy, Morrow’s board said it had been trying to secure a new industrial investor and finance, and that “several of the ongoing efforts had reached an advanced stage”.

But these talks “could not be concluded within the constraints imposed by the group’s liquidity situation”, it said, blaming the failure on “the capital requirements inherent in an early industrialisation phase” combined with “increased capital costs, delays in the industrialisation process and a more restrained investment market”.

Northvolt’s bankruptcy may have also damaged Morrow’s attempts to raise money. Last May, Bacher himself acknowledged that it “didn’t help”. 

Morrow also cited oversupply in the global battery market, and the resulting downward “price pressure”. The price of LFP batteries fell by nearly half between 2022 and 2025, eating into producers’ profit margins, according to the International Energy Agency.

The hefty state investment in Morrow has generated controversy in Norway following its bankruptcy. The leader of the right-wing Progress Party (FrP), Sylvi Listhaug, has said Norwegian taxpayers’ money was wasted on an unviable business. 

But others, like Poliscanova and the head of the European Battery Alliance trade association Emma Nehrenheim, told Climate Home News that if Europe wants a battery industry, it will need to back home-grown manufacturers whole-heartedly.

“Valley of death” kills startups

As European battery manufacturers work to perfect and scale up their technology and processes, they face “a valley of death” with severe competition and little patience from investors or battery customers who “can easily buy them from China”, Poliscanova said.

Startups like Morrow typically raise project financing to get them off the ground, according to Nehrenheim. In the period between that finance ending and reaching profitability, they have to rely on money they set aside as a project reserve. 

If they underestimate this reserve, which she said is easy to do when setting up a new factory making a new product, they need more money to bridge the gap. This can come from specialised bridging investors, from customers or from governments.

For Morrow, however, the money did not arrive in time.

Nehrenheim – who was previously Northvolt’s chief environmental officer – said it was a characteristically European failure from investors.

“We’re not good at this,” she said. “We’re not bold enough to compete with Silicon Valley or the Asian (countries), who have been scaling industry now for decades.”

Clean energy sovereignty vs price

Since Northvolt’s bankruptcy filing, the European Union has announced policies to support European battery makers.

It is introducing a €1.5 billion ($1.7 billion) “battery booster“, providing interest-free loans to battery manufacturers. It is considering putting tariffs on imported batteries, subsidising European battery makers and tying electric car incentives to locally made batteries through the Industrial Accelerator Act. None of these policies are yet in place.

With trade disputes rising up the agenda of UN climate talks, Poliscanova conceded that such moves are protectionist, although she said she prefers to call them industrial policy.

“Honestly,” she said, “the EU and the UK are the two large global blocks left that don’t have such industrial protectionist policies. India has it, Brazil has it, China has it, the US has it – we’re literally the last fool standing thinking that [the World Trade Organization] is the way to go.”

Li Shuo, China Climate Hub director at the Asia Society Policy Institute, said that the trade-offs between cheap foreign batteries and more expensive European ones “need to be discussed honestly”.

“How much higher are Europeans willing to pay?” he said. “How much delay in climate deployment is acceptable? Can we really decarbonise and de-risk at the same time? How long can politicians condemn cheap Chinese imports while consumers simultaneously demand affordability?”

While European policymakers want to fight China, the average European just wants a cheap battery, he added.

Closing the cost gap

But once European battery makers scale up, the price gap with Chinese batteries will shrink, Poliscanova said.

While German LFP battery cells are 90% more expensive than those made in China, scale-up could close this gap to a “sovereignty premium” of just 25% by 2030, Transport & Environment estimates.

Nehrenheim acknowledged that most of Europe’s batteries will continue to come from Asia or the United States. “I’m very happy for that because they’re scaling fast and they get great support subsidies in their respective countries to supply us to help us in the [energy] transition,” she said.

But European-headquartered companies must make at least a quarter of the region’s batteries, she said, otherwise if supply is disrupted – whether by geopolitical factors, a pandemic or natural disaster – the industry will have nothing to scale up from.

Nehrenheim said she was almost 100% confident that Morrow’s factory will continue to produce batteries. The company said it expected a court-appointed bankruptcy administrator to assume control over the company’s assets and operations.

Citing investors’ €1.4 billion ($1.62 billion) reprieve of Swedish green steelmaker Stegra in April, Nehrenheim said there were reasons to be hopeful about Morrow’s survival as Europe demands batteries for diverse uses beyond cars – from energy storage to drones and forklift trucks.

“Somebody will pick this up,” she said.

‘Energy Vampires’: Greenpeace calls for moratorium on data centres as new report reveals frenzied rollout would derail energy transition

Published

on

SYDNEY, Wednesday 27 May 2026 — A new report from Greenpeace Australia Pacific and independent expert Ketan Joshi reveals how the frenzied rollout of AI data centres in Australia is set to derail the renewable energy transition, entrench gas and turbocharge climate pollution, prompting calls for an urgent moratorium on data centre approvals until appropriate guardrails are in place.

The report, Energy Vampires: the AI data centres draining Australia, reveals the staggering scale of data centre growth in Australia, set to follow a US path of emissions blowout and rising community opposition to the resource-hungry facilities. The report exposes the links between the data centre lobby and the gas industry, who are using data centre growth to justify extracting more gas.

Greenpeace Australia Pacific is calling on the Federal Government to urgently implement a moratorium on the construction and approval of new data centres, until appropriate regulations and safeguards have been put in place to protect the climate and communities.

Key findings:

  • Data centres are already failing to cover their own demand with additional renewable energy, and resisting calls to mandate that they do.
  • At its peak, Australia’s biggest proposed data centre, the 1GW Mamre Road Data Centre Campus in Western Sydney, will generate annual emissions equivalent to 560,000 petrol cars, or all domestic flights within NSW in 2023.
  • There are early signs of a data centre-fuelled gas boom in Australia, including proposals for new on-site gas, as seen in the US. 
  • Cloud Carrier’s proposed gas-fired data centre in NSW would wipe out the state’s entire projected 2028 emissions cuts.
  • Even if only 1 in 4 new Australian data centres were powered by new on-site gas, it would result in 2.8x higher total emissions compared to using grid power.

Joe Rafalowicz, Head of Climate and Energy at Greenpeace Australia Pacific, said: “Australia is completely unprepared for the magnitude of impacts of the AI-driven data centre frenzy. Data centres are being rolled out at a feverish pace, with some of the largest planned for Australia consuming as much energy as Adelaide. The recent federal and state energy minister communique is a positive first step towards regulating the data centre industry, and managing its impact on the energy transition and the communities where they’re being built.

“But we should all be concerned by the extreme lack of scrutiny being applied to the companies leading the data centre charge in Australia and their proposals. Without strong, legislated standards, we risk replicating the disastrous US pattern, where Big Tech corporations have carte blanche to drain energy and water, and build new, polluting gas and diesel-powered plants to fuel their operations. This has seen mounting community opposition that transcends party politics, something we’re beginning to see here in Australia.

“Greenpeace is calling for a moratorium on new data centre approvals and construction until we have clearly defined, enforceable regulations and standards in place to govern this industry — essential if we hope to avoid the alarming outcomes outlined in this report.

“Australia is not a playground for Big Tech corporations. It is time our leaders stepped up and took seriously their role as custodians of our resources and protectors of our society and environment.”

Ketan Joshi, independent report author and climate expert said: “Impatience is not a virtue. The reckless data centre buildout is heaping massive new load onto the grid, meaning renewables have to run harder just to stay in the same spot. Currently data centres increase coal and gas output and delay shutdowns, while plugging polluting gas into data centres does the damage directly instead.

“Unless the data centre industry builds no new fossil fuels and far more new renewables than new demand, we end up worse off. Australia’s gas industry sees a lifeline in an unchecked data centre frenzy, and the feeling seems to be mutual.

“Data centre demand projections keep jabbing upwards each revision, and emissions projections keep getting worse. Everywhere in the world facing this frenzy sees the same trend.

“Data centre moratoria have bipartisan support in countries around the world as the only path to reintroducing careful, considered governance of data centre growth. In the context of an irrational, unjustified panic, a temporary pause brings reason and rationality, along with bringing power to communities.”

Energy Vampires: the AI data centres draining Australia

Published

on

A new report from Greenpeace Australia Pacific and independent expert Ketan Joshi reveals how the frenzied rollout of AI data centres in Australia is set to derail the renewable energy transition, entrench gas and turbocharge climate pollution, prompting calls for an urgent moratorium on data centre approvals until appropriate guardrails are in place.

The frenzied rollout of AI data centres in Australia is rushing through massive new projects, which will derail Australia’s energy transition unless the government urgently intervenes.

Key findings

  • The frenzied rollout of AI data centres in Australia is rushing through massive new projects, which will derail Australia’s energy transition unless the government urgently intervenes. Our conservative assumptions mean this impact is understated, in this analysis.
  • Australia’s biggest proposed data centre, the 1GW Mamre Road Data Centre Campus in Western Sydney, will generate peak annual grid emissions equivalent to that produced by 560,000 petrol cars for a year or all domestic flights within NSW in 2023.

  • Data centres already fail to cover their own emissions with new renewables and their rollout will dramatically hold back Australia’s energy transition.
  • No data centre operator analysed in this report adequately proves their claim of driving Australia’s renewable energy growth. Claims they are doing this through truly “additional” new power purchasing agreements for renewable energy are unsubstantiated.
  • There are early signs of a data centre-fuelled gas boom in Australia, which will come with massive, nationally significant climate costs. For example, the Tamboran proposal for the Northern Territory would effectively double the state’s emissions. In NSW, Cloud Carrier’s proposed gas-fired project would wipe out NSW’s entire projected 2028 emissions cuts.

  • Even if only 1 in 4 new Australian data centres were powered by new on-site gas, it would result in 2.8x higher total emissions compared to using grid power.
  • New analysis shows that on-site gas for data centres globally could fuel emissions that exceed Brazil’s total power grid emissions by 2030.
  • Fossil fuel corporations are quietly joining the data centre lobby group as members, and sponsoring and attending technology industry conferences. The two industries are reinforcing each other’s talking points and PR spin.

  • Data centre operators do not disclose the customers of an individual facility, the purpose of the computations performed there, or site-specific energy consumption, despite the industry’s defense of its ‘critical infrastructure’ status or claims of transparency. It is a matter of public record that AI is being used for abuse, war and other human rights violations.
  • Data centres can be ‘right sized’ through community ownership schemes, well-deployed AI software and strict moratoria to allow for democratic governance of this industry.

This report recommends:

  • An urgent moratorium on data centre development until safeguards are legislated
  • Binding, legislated standards for AI development, including substantiated claims of additional renewable energy
  • Full disclosure of services delivered, emissions, finances and energy use, per project
  • Full assessment of compliance with human rights frameworks
