UN climate chief Simon Stiell has said he hopes to see fewer people attend the annual COP climate negotiations after participants at COP28 in Dubai last December hit a record high of nearly 84,000.

Stiell said this month that he personally “would certainly like to see future COPs reduce in size”, telling an audience at London’s Chatham House think-tank that “bigger doesn’t necessarily mean better”.

In Dubai, where the 2023 summit was held from November 30 to December 13, the Expo City site was so large that important delegates were ferried around on golf buggies while electric scooters were available to get around the public area, known as the Green Zone.

“Size does not necessarily translate to the quality of outcomes,” Stiell said in London, noting that the UN climate change secretariat (UNFCCC) is discussing the issue with the hosts of COP29 in Azerbaijan this year and COP30 next year in Brazil.

Last week, Climate Home reporters visited the COP29 host city of Baku, the capital of Azerbaijan – on a tour sponsored by the COP29 presidency – and also the location of COP30, the Brazilian Amazon city of Belém, to see how preparations are going for the November 2024 and 2025 gatherings.

Azerbaijan’s government is expecting just 40,000 people to come to the Baku Olympic Stadium for the talks this year, while Belém’s remoteness, congested roads and lack of hotels are likely to substantially limit how many people can attend the “Amazon COP”.

The number of people attending COPs has shot up in recent years. Close to 40,000 people went to COP26 in Glasgow, around 50,000 were in the Egyptian resort of Sharm el-Sheikh for COP27 and nearly 84,000 headed to Dubai last year. But most of the 28 COPs held since 1995 have been attended by fewer than 10,000 people.

Just over half of last year’s participants belonged to government delegations, with most of the rest comprising staff working at the conference or activists from non-governmental organisations (NGOs).

In practice, the boundaries of these categories are blurred though, as government delegations often include business representatives, NGO employees, journalists and others.

Baku’s Olympic Stadium

The government of Azerbaijan will host COP29 in the country’s Caspian seaside capital, Baku. A member of the organising committee told Climate Home they are expecting around 40,000 people.

The government has not had much time to prepare, as it was only tasked with the presidency last November at COP28 after Eastern Europe’s geopolitical divisions delayed the decision on which country would host the summit.

But it already has a venue: the Olympic Stadium on the outskirts of Baku. According to state media, COP29 chief operations officer Narmin Jarchalova said temporary structures will be built around the stadium to accommodate the negotiations and side events. These are likely to be in car-park areas.

The city is used to hosting major events. Ten thousand come each year for Formula One’s Baku Grand Prix and the 69,870-capacity Olympic Stadium has hosted the 2015 European Games, big concerts, the 2019 Europa League football final and Euro 2020 matches, although no Olympic Games despite the name.

Climate Home visited the area in April while in Baku, as part of a press trip organised by the COP29 presidency team. The stadium is connected to the city centre, where most hotels are located, by a Soviet-era metro railway with a one-way journey taking around 45 minutes.

A car journey should take about half of that, 20 minutes, but heavy traffic gridlocked the main roads in and out of Baku when Climate Home visited.

Climate Home asked the COP29 team for information on how the temporary COP facilities will be built, powered and heated sustainably during the summit, but had received no response at the time of publication.

In February, Climate Home revealed that the government had told hotels in Baku not to sell rooms for COP29’s November 11-22 dates until further notice.

In London this month, UN climate chief Stiell said, with regard to the number of participants, that “we have an opportunity with Azerbaijan and we’re engaging with them”. He did not give further details.

COPs usually feature one big climate demonstration on the middle Saturday of the two-week talks. The UNFCCC is talking to the COP29 team about how this will be enabled.

In a meeting at the energy ministry last week, COP29 CEO and deputy energy minister Elnur Soltanov told journalists, including Climate Home, that these discussions were “fruitful”.

Human rights groups like Freedom House say Azerbaijan does not respect freedom of assembly. Police violently arrested opposition protesters in 2019.

Soltanov was asked if the climate march will be allowed to take place in the city, which is governed by Azerbaijan’s police force, or only in the COP29 venue, which is under the jurisdiction of UN security guards.

He replied that “this is too specific a question” but said that protest is “part and parcel of people expressing their views, their anger, their desperation”.

Brazil’s Amazon COP

On Belém, which is in northern Brazil near the Amazon rainforest, Stiell said he was “actively discussing with the Brazilians how we can reduce the size of the COP so that the logistics of it can be supported at that hosted destination”.

Last June, Brazilian climate ministry official André Corrêa Lago told local media he was expecting 40,000-50,000 people. But there are concerns that the city will struggle to cope with those numbers.

Belém is not a major tourist destination and has less than 6,000 hotel rooms. Even at last year’s Amazon Summit – a smaller event than a COP – participants reported difficulty finding rooms and rates soared.

Construction workers are currently turning a 1.6 km-long disused airport runway into the Parque de Cidade (City Park), which will be the size of about 70 football pitches. The park and its new buildings will be the main COP30 venue.

The government of Pará State says it is almost one-third finished. The federal government, meanwhile, is reportedly considering hosting part of COP30 in bigger cities like Sao Paulo or Rio de Janeiro.

A spokesperson for the federal government told Climate Home that “all possibilities to enable the reception of delegations and visitors are being evaluated”.

As well as the park and its new buildings, some of the conference will be held in an existing conference centre on the park’s southern tip called The Hangar – which hosted last year’s Amazon Summit.

For COP30 delegates though, finding a hotel room and getting to the venue are likely to be challenging. 

A spokesperson for the COP30 organising committee said last week that while 84,000 people went to COP28, the peak daily attendance was just 41,000 at the beginning of the conference when heads of state made their speeches.

The spokesperson told Climate Home the organisers are looking at bringing in cruise ships for COP participants to sleep on, refurbishing schools to serve as hostels and encouraging people to rent out their rooms on Airbnb.

To promote the “modernisation” of the city’s existing hotel rooms, the government has given hotel operators tax exemptions on purchases for new equipment like minibars, televisions and air-conditioning.

The city’s airport, which the government aims to improve before COP30, has few regular international connections and is over three hours by plane from Brazil’s major hubs like Sao Paulo and Rio de Janeiro. 

There are no trains to Belém and getting the bus from Rio or Sao Paulo can take more than two days.

Even inside the city, transport is challenging. The roads are congested, particularly in the centre where most of the hotels are, during rush-hour and when it rains.

The authorities have tried to solve the problem by widening roads and building dedicated bus lanes for a Bus Rapid Transit system.

While these are being constructed, they have made traffic worse – but the body in charge told Climate Home work is progressing according to schedule and should be completed by the second half of 2024 – well before the UN climate summit the following year.

“The new fleet will reinforce the capital’s transport system for COP30,” said a spokesperson for the Metropolitan Transport Management Centre, adding that 40 of the 265 new air-conditioned buses will be electric.

Nonetheless, the remoteness of the location is likely to translate into a bigger carbon footprint for delegates travelling from overseas.

While COPs have a sizable carbon footprint, researchers investigating misinformation have found this is often exaggerated on social and traditional media by those trying to undermine climate action.

Examples include pictures of private jets with captions falsely associating them with COP or of biofuel generators with captions erroneously claiming they are diesel.

Questioned about COPs’ carbon footprint by an audience member at London’s Chatham House, UN climate head Stiell replied that “at every COP, we get the reports – how many private planes [and] the CO2 footprint for hosting those COPs”.

But, he added, “taking a very pragmatic view, we need the right people around the table in order for this process to work and there will be a cost to that. How you ensure that those that are present are the ones necessary to contribute positively to the process is also important.”

“Next year is too late for regulations”: Beetaloo Energy’s 2GW gas-powered AI data centre a “disaster proposal” destined to cause climate chaos

Published

on

SYDNEY, Wednesday 22 July 2026 — Beetaloo Energy has secured land from the NT Government for a massive $40 billion “hyperscale” AI data centre near Darwin, which would be powered by 2 gigawatts (GW) of gas power fracked directly from the Beetaloo basin, prompting calls from Greenpeace for urgent federal legislation.

The proposal marks a dangerous escalation in the AI data centre industry’s expansion, which threatens to entrench fossil fuel infrastructure for decades and put immense pressure on the region’s fragile water resources — while continuing to be unregulated.

Joe Rafalowicz, Head of Climate and Energy at Greenpeace Australia Pacific, said: “This disaster proposal for a 2GW gas-powered AI data centre in the NT is a shocking example of the unchecked expansion of hyperscale data centres in Australia. It is also, critically, more evidence for the urgent need for a moratorium on all new data centres until strong, binding regulations are put in place to protect our communities and climate.

This proposal mirrors the frenzied, unchecked expansion currently wreaking havoc on communities in the US. We are seeing cowboy data centre operators treat Australia like a playground, steam-rolling ahead with projects that would lock down precious water resources and spike emissions, despite the overwhelming community opposition.

Every day, more councils, communities and environmental groups are joining Greenpeace’s call for a moratorium on data centres, yet as of today there is still no system of safeguards or rules in place to regulate these companies.  

While Beetaloo Energy and the NT Government prepare to bulldoze ahead with this climate and water disaster, the Prime Minister is asleep at the wheel, promising to legislate a vague set of standards next year.

Next year is too late, and anything less than mandating data centres cover their own energy demand, and then some, with new renewable energy is not enough.”

Allegations of harms at China-backed transition minerals projects rise

Published

on

Reports of human rights and environmental abuses linked to Chinese companies’ overseas investments in the mining and refining of minerals needed for the clean energy transition are on the rise, research by a monitoring group has found.

The number of recorded allegations of harm at projects tied to Chinese firms have increased every year since 2021, rising to 148 in 2025, according to the Business and Human Rights Centre (BHRC). On Wednesday it released new data showing that a total of 434 allegations of abuse were made against Chinese-backed projects over the five-year period in projects across the world.

The world’s top cleantech manufacturer, China is also the leading financier of critical minerals projects worldwide. The country has committed more than $120 billion in foreign direct investment into mineral mining and processing since 2023, Australian think-tank Climate Energy Finance recently found.

“China plays a central role in global transition mineral supply chains, and as such has a unique opportunity to raise the bar on human rights and community engagement at every stage of mining,” said Michael Clements, BHRC’s executive director.

“While there have been encouraging developments, from stronger regulations to more company engagement, there remains a gap between human rights commitment and action,” he said.

The report comes as communities affected by Chinese-backed mineral projects have filed the first two cases to a Beijing-based mediation mechanism intended to bring willing Chinese companies to the discussion table with affected communities.

Allegations of harms on the rise

BHRC’s latest analysis – including data for the period 2023-2025 – covered mining, smelting and refining projects for 11 minerals considered key to manufacturing clean energy technologies such as batteries, EVs and solar panels needed to move away from climate-heating fossil fuels.

The highest number of abuses was recorded in Indonesia, the world’s largest producer of nickel, which is used to make EV batteries. After the Indonesian government banned exports of raw nickel, Chinese firms invested billions of dollars to develop a large-scale nickel smelting and processing industry in the Southeast Asian country, largely powered by coal.

Other countries with a high number of recorded harms include the Democratic Republic of Congo, where Chinese firms dominate cobalt and copper production; Myanmar, where unregulated rare earths mining has caused widespread environmental destruction; Serbia, where Chinese-backed mining of some of Europe’s most significant copper and gold deposits is swallowing land and homes, and Zimbabwe, where Chinese investments have turned the nation into Africa’s top lithium producer.

Growing risks for people and nature

Allegations tracked by BHRC included negative impacts on local livelihoods, health and land rights, workers’ health and safety and work-related deaths, as well as water pollution and environmental contamination. In addition, 18 people were attacked for raising concerns about Chinese transition mineral projects between 2023 and 2025.

The report shows that 10 Chinese companies, including Zijin Mining, Tsingshan Group and Zhejiang Huayou Cobalt, accounted for nearly two-thirds of all allegations recorded in the last five years. It found that some Chinese companies “still appear to turn a blind eye to these issues” but noted that several others have been more responsive to allegations of abuse. However, even among companies with human rights policies, implementation remains a challenge, BHRC warned.

    Zijin Mining and Zhejiang Huayou Cobalt repeatedly responded to the allegations of harm by saying they take environmental and social risks seriously and adhere to international standards. Tsingshan Group never responded to BHRC’s requests for comment.

    Platform for dialogue between communities and Chinese firms

    At the same time, Chinese authorities have made “significant progress” on introducing a more specific framework for managing environmental and social risks in overseas investment, BHRC said.

    This includes global consultation on a draft Sustainable Mining Code, adherence to UN guiding principles on business and human rights, and greater emphasis on oversight of companies operating overseas.

    The China Chamber of Commerce of Metals, Minerals & Chemicals Importers & Exporters (CCCMC) set up a mediation and consultation mechanism intended to provide a platform for dialogue between affected communities or civil society groups that have raised concerns and Chinese companies.

    More than three years since its launch, the mechanism has now received its first two complaints from local communities and many more are considering filing a case, Margaux Day, executive director at the nonprofit Accountability Counsel, told an event hosted by Climate Home News last month.

    “This is incredibly exciting in that it fills a governance and accountability gap where often communities who are seeking to protect their rights and the environment can’t reach someone who will respond to them,” she told the panel discussion at London Climate Action Week.

    Climate Home News understands that the complaints were filed by communities in Latin America and Southeast Asia over labour rights and resettlement issues. No information about the cases has yet been made public. The mechanism’s secretariat did not respond to Climate Home News’ questions.

    The mechanism was set up after the Chinese regulator for banks and insurers called on investor-level institutions to establish complaints bodies to hear from communities outside of China. But whether the new initiative will prove effective in tackling grievances remains an open question.

    “Real potential” for better mining practices

    Participation in the mechanism is voluntary for Chinese firms and it doesn’t have a fact-finding function, nor can it impose provisions for compensation or compliance with human rights standards.

    But Day told Climate Home News that, if successful, it could bring companies to negotiate an outcome that is better for people and the planet and leads to more sustainable mining practice.

    Chen Yu, an independent China advisor for campaign group Global Witness, agreed that the mechanism holds “real potential”.

    “There exists nothing else at a similar level to promote dialogue between communities and Chinese mining companies in particular,” she said.

    For companies, the mechanism opens “a channel for problem-solving and dialogue with communities”, she added, as “Chinese companies often remain cautious of approaching affected communities directly, afraid of making the problem bigger”.

    However, Chen said the mechanism remains at an early stage of development, faces resourcing challenges and is not yet sufficiently understood by communities in mining areas or Chinese firms.

    To help it address some of these challenges, the secretariat is currently seeking technical support from a range of organisations, including civil society groups. But, Chen said, “it will take time for the mechanism to show its value”.

    Energy transition policymaking must evolve to fit an age of rupture

    Published

    on

    Andreas Sieber is head of political strategy at 350.0g. Cat Abreu is director of the International Climate Politics Hub.

    From the US abduction of Venezuela’s president at the start of this year to the Iran war which rumbles on, disruption is the new normal for global geopolitics, more often than not linked to conflict over supplies of oil and gas. 

    Events so far in 2026 – driven largely by the desire of the Trump administration to grab control of fossil fuels around the world – show that the climate community’s approach to energy diplomacy will have to evolve if we are to operate effectively and push for climate action in such a volatile landscape.

    Today’s climate and energy governance must be able to cope with trade wars, genocide, fascism, spiralling inequality and challenges to multilateralism. The increasingly dominant paradigms of economic competitiveness, energy security and green industrialisation can help drive the transition but they also challenge our collective mission to deliver an equitable green shift.

    US-China rivalry dominates

    Longer-term geopolitical trends that are seeing power move from West to East and North to South have fuelled a US–China “superpower rivalry”, which is pulling the global economy apart and reining in trade.

    A key question will be how the fracture “lines” are drawn: by the US and China, or also by other countries or blocs? Many governments will try to remain “in the middle” between the two giants to capture economic gains from both sides. Yet despite the language of “strategic autonomy”, Washington and Beijing may be in a position to force choices via market access, export controls and sanctions.

      At first glance, this may not seem particularly relevant for climate and energy politics. But Huawei’s exclusion from 5G operations across the political West and India following the so-called Clean Network Campaign by the US government serves as a warning of what could happen to climate green tech.

      And the recent debate to cut out Chinese inverters from European markets follows the same pattern – US security forces perceive a risk and start encouraging their allies to drop Chinese technology.

      The new drivers: competition and security

      Despite this fracturing geopolitical and economic context, energy transition is still happening. To ensure it is effective and equitable, we need to understand what is driving it and how to adapt climate politics so that it better responds to these drivers.

      Put simply, China is supplying the world with low-cost renewables (roughly 60% of critical wind and 80% of solar components), batteries, EVs and other key elements. Other countries now also want their piece of the green tech pie and are forming industrial policies to get it.

      It is this new competitiveness-driven logic that will shape the quest for decarbonisation, which has shifted from cooperating around the cost of tackling climate change to rivalry for the benefits of climate action.

      Over 90% of new renewables projects are now cheaper than fossil alternatives. Gas-fired power is 3–4 times more expensive than solar and wind. In 2015, most decarbonisation policies were “traditional” emissions-cutting strategies like carbon pricing or net zero dates, whereas green industrial policies now underpin the majority.

      Iran war could boost fossil fuel phase-out push, says Colombian minister

      Meanwhile, security has become a central driver of energy politics. We are living through the second major fossil fuel crisis in just four years. Elevated oil and gas prices will impose up to $1 trillion in additional costs on the global economy by the end of the year if disruption continues in the Strait of Hormuz. Fossil fuel supply chains have exposed countries to conflict, coercion and brutal price shocks.

      Fossil fuel volatility destabilises whole economies – higher fuel costs drive up food prices, increase political instability, and push millions into poverty and hunger. This incentivises governments to shield themselves from global shocks, especially in countries that are net fossil fuel importers and home to roughly three-quarters of the world’s population. 

      Yet security fears can cut both ways. The same instability that makes fossil fuel dependence untenable is also sharpening concern over China’s dominance of critical clean technologies and supply chains.

      Equity, cooperation and the opportunity for change

      Developing countries benefit from the rapid uptake of renewables enabled by low-cost Chinese technologies. But significant fiscal space and public investment is needed for the electricity grids and infrastructure required to fully unleash the energy transition, as well as for green industrialisation to diversify revenue streams.

      Despite this, industrial-scale domestic production and ownership often remain out of reach for too many countries that lack the fiscal space to allow green supply chains to flourish and compete with their traditional industrial base. But more just and diversified green tech supply chains could be achieved with concomitant support.

      Can giant batteries unlock Africa’s green industrial future?

      For the first time in decades, the international order is being substantially reshaped. If within this context, decarbonisation is increasingly driven by green industrial policy, energy security and competitiveness, the climate policy community must better anticipate where these debates are moving. We must speak the same language, and enter the forums where decisions are made, including security, trade and bilateral or trilateral spaces.

      We should build on an enlightened self interest recognising that cooperation remains essential and beneficial. This includes using the UN climate process differently: less as an ever-expanding negotiation machine, and more as a space for norm-setting, political alignment and deal-making. In an age of fragmentation, effective cooperation must not only be framed as necessary but thought of as a strategically compelling source of resilience and shared advantage.
