An essential guide to the week’s key developments relating to climate change.

This week

Energy outlook

DEMAND SURGING: The International Energy Agency (IEA) published its annual World Energy Outlook report – a “comprehensive” summary of global energy trends – the New York Times reported. The outlet said, over the next decade, the world will add the equivalent of Japan’s annual electricity demand each year, driven by demand for new factories, electric vehicles, air-conditioners and data centres. (Axios said the IEA included a “reality check” about data centre demand, which would only make up a “small share” of growth by 2030.)

AGE OF ELECTRICITY: Reuters reported that the “world is on the brink of a new age of electricity”, with global fossil fuel demand set to peak by the end of the decade. The newswire added that “surplus oil and gas supplies could drive investment into green energy”. The Wall Street Journal said clean energy would grow faster than global energy demand, becoming the largest source of power in the mid-2030s, according to the IEA. Carbon Brief has just published an in-depth analysis of the report’s findings. (See Captured below.)

COP16 kickoff

BIODIVERSITY TALKS: The COP16 biodiversity summit begins in Cali, Colombia, on Monday. It will be the first set of UN biodiversity negotiations since the world’s nations agreed a landmark deal in 2022 to “halt and reverse” nature loss by the end of the decade.

MISSED PLEDGES: Joint analysis published on Tuesday by Carbon Brief and the Guardian showed that more than 85% of countries are set to miss the UN’s deadline to submit new nature pledges, known as national biodiversity strategies and action plans (NBSAPs).

WHAT TO WATCH: Carbon Brief’s team of journalists on the ground in Cali will host a webinar on Tuesday at 3pm UK time to discuss the key issues facing negotiators and answering questions. (Sign up for free.) Through the fortnight of the talks, they will also be scrutinising each new draft negotiating text as it lands, explaining areas of disagreement and updating Carbon Brief’s interactive text tracker.

After the storm

DEVASTATING DAMAGES: Hurricanes Helene and Milton are “likely” to each rack up costs of more than $50bn, the Associated Press reported. According to the newswire, “government and private experts” say the hurricanes could join the “infamous ranks” of Katrina, Sandy and Harvey – which are among the eight US storms to have ever caused damages of more than $50bn.

PAYOUTS: The US Small Business Administration has exhausted funds for its disaster loan program following increased demand from Hurricane Helene, Reuters warned. Officials said the program needs about $1.6bn amid heightened demand following Hurricane Helene, according to the Hill. The Financial Times estimated that Milton alone will lead to about $36bn of insurance payouts for the private sector.

Around the world

  • DIRTY ENERGY: Burning household rubbish to make electricity is now the “dirtiest way the UK generates power”, BBC News reported.
  • COP BID: Australia has launched a bid to host the COP31 climate summit in 2026 in Adelaide, according to the Guardian.
  • FINANCE FAIL: The EU unveiled its negotiating stance for the COP29 climate talks next month, but did not address how it will boost funding for developing countries, according to Bloomberg.
  • CURBING COAL: The US Supreme Court allowed the Environmental Protection Agency to move ahead with its plans to limit carbon emissions by power plants, despite a pending challenge from 27 mainly-Republican states, the New York Times reported.
  • WARNING MESSAGE: Activist group Friends of the Earth warned the UK government to drop its support for a Mozambique gas project “embroiled in allegations of abduction, murder and rape”, said Politico.
  • WIND POWER: A Chinese company developed the world’s “most powerful” floating offshore wind turbine with a capacity of 20 megawatts, state news agency Xinhua said.

Latest climate research

  • Recent floods that killed at least 244 people in Nepal were driven by rainfall made “about 10% more intense” by human-caused climate change, according to a rapid attribution study.
  • Drought and aridity are already having a “significant impact” on internal migration – especially in arid and “hyper-arid” regions of southern Europe, South Asia, Africa and the Middle East and South America – new research found.
  • Many people in the US are experiencing “psychological distress” from climate change, but those who do are more involved in collective climate action, a new study said.

Solar generation is set to quadruple by 2030, sending coal power tumbling

Electricity generation from solar is set to quadruple by 2030, sending coal power tumbling and becoming the world’s largest source of electricity by 2033, according to Carbon Brief analysis of the International Energy Agency’s World Energy Outlook. The report finds that global CO2 emissions are set to peak “imminently”, as the “age of electricity” sends fossil fuels into decline. See Carbon Brief’s in-depth coverage of the report.

Is global warming ‘accelerating’?

A recent “surge” in global warming is not statistically “detectable”, according to a study published this week. But does this mean it is not happening? Carbon Brief speaks to the lead author of the study and explores the debate on a warming acceleration.

Global temperatures are soaring. Last year was the hottest year on record, with global surface temperatures reaching 1.34-1.54C above pre-industrial levels. But 2024 is already setting blistering new records and is expected to knock 2023 off the top spot.

Against this backdrop of ever-worsening heat, a new study in Communications Earth and Environment used statistical methods to see whether an acceleration in global warming could be formally detected.

The authors find a “changepoint” in the rate of warming around the year 1970, but find no “statistically detectable” acceleration since then.

Dr Claudie Beaulieu is the paper’s lead author and an associate professor in the Ocean Sciences Department at UC Santa Cruz. She told Carbon Brief: “If an acceleration in global warming is occurring, the size of that acceleration is either too small or too recent to robustly detect it in globally-averaged surface temperature records.”

However, some scientists questioned the methods used in the study. Prof Richard Allan, a professor of climate science at the University of Reading, said the surface warming data used in this study is “influenced by natural variation”. He argued that “when all lines of evidence are scrutinised” – such as satellite data and ocean measurements – “it is apparent that climate change is accelerating rather than continuing steadily”.

Carbon Brief’s climate science contributor, Dr Zeke Hausfather, published a factcheck earlier this year on the acceleration in global warming. Assessing observations and climate model output, he concluded that “that there is increasing evidence of an acceleration in the rate of warming over the past 15 years”.

Beaulieu told Carbon Brief that present-day discussion about an acceleration in warming is similar to the debate over a warming “hiatus” about a decade ago. She continued:

“Back then, also using statistical methods, we showed that a ‘hiatus’ in warming was not detectable. With hindsight of more years of observations it is now obvious warming had just continued leading to the record heat of 2023. We need to keep monitoring.”

Dr John Kennedy is the co-chair of the World Meteorological Organisation (WMO) expert team on climate monitoring and assessment and scientific coordinator for the annual WMO State of the Global Climate reports.

He warned that this statistical method can mean waiting many years for warming – or a lack of warming – to be detectable. In a blog post earlier this year, Kennedy wrote:

“One thing that became clear during the ‘hiatus’ is that this kind of analysis is the kind of thing you do when you’re set (for whatever reason) on being the last person to know there is a hiatus.”

He added: “There are good physical reasons to expect an increase in the underlying warming.”

Beaulieu does not refute that warming might be accelerating. She said that “the point of the paper is that it will take additional years of observations to detect a sustained acceleration”.

Watch, read, listen

CLIMATE LINGO: Author and climate change activist Genevieve Guenther joined the Drilled podcast to discuss her new book, The Language of Climate Politics, which digs into rhetorical devices that she says are being used to slow or block climate action.

FAILING SINKS: “Is nature’s carbon sink failing?” asked a feature in the Guardian. The article warned that forest, plants and soil absorbed almost no carbon in 2023, and asked whether this “could rapidly accelerate global heating”.

FARM SUBMERGED: A short video by BBC News follows Nigerian farmers discussing the impacts of climate change on their livelihoods and highlights possible solutions.

Trump Administration Abandons Fight Against Wind Energy as Clean Energy Output Surges

Published

on

The clean energy sector is showing resilience despite challenges thrown at it by a hostile White House, a recent report found. A string of legal victories has further dampened the Trump administration’s efforts to halt wind and solar power.

The Trump administration has abandoned its effort to halt wind energy projects across the United States and dropped its challenge to the court ruling that tossed President Donald Trump’s order freezing federal permitting and leasing for wind projects. States that challenged the order hailed the development as one of the most significant legal victories against the Trump White House’s campaign against the energy transition.

Analysis: UK’s EV drivers are now saving £1,100 each a year – and £3bn in total

Published

on

Amid reports that the government could weaken the UK’s electric vehicle (EV) targets, Carbon Brief analysis reveals the nation’s EV drivers are saving more than £1,100 a year in fuel costs, compared with running a petrol car.

Battery EVs (BEVs) are roughly four times more efficient than combustion-engine cars, making them far cheaper to run – particularly since the Iran crisis caused a spike in fossil-fuel prices.

The savings from driving BEVs are also more than three times higher than for “plug-in” hybrids (PHEVs), which evidence shows are mostly driven with their combustion engines.

In total, the more than 2m BEVs, 1m PHEVs and 100,000 electric vans on UK roads are saving drivers around £3bn a year, Carbon Brief’s analysis shows, as illustrated in the figure below.

In addition, these EVs are avoiding the need for nearly 2.5bn litres of fuel and cutting carbon dioxide (CO2) emissions by nearly 7m tonnes each year.

Despite recent news that EVs are now cheaper to buy than petrol cars, as well as having far lower running costs, BBC News says the government is “set to water down” its EV sales targets.

The broadcaster explains that the current goal, under the UK’s “zero-emissions vehicle” (ZEV) mandate, is for 80% of new car sales to be BEVs by 2030.

It says that the government is set to consult on weakening this to between 50% and 70%, following “lobbying” by carmakers and trade unions.

According to the Sunday Times, prime minister Keir Starmer “is understood to have overruled the energy secretary [Ed Miliband] after sustained pressure from industry, the Unite union and Peter Kyle, the business secretary”.

The car industry has consistently claimed there is insufficient demand for BEVs to meet the targets under the ZEV mandate, yet the government says manufacturers have “over-complied” to date. Independent analysts say the industry is on track to continue beating the ZEV mandate goals.

The industry has been able to beat its targets by using a wide range of “flexibilities”, which were introduced after a previous round of lobbying. These allow carmarkers to meet part of their EV targets by selling more efficient combustion cars, such as hybrids and plug-in hybrids.

The ZEV mandate is the single-largest part of the government’s plans to meet its legally binding climate goals over the next decade.

The advisory Climate Change Committee (CCC) previously warned that the extra flexibilities would result in a larger number of hybrids being sold, at the expense of battery EVs.

When it consulted on the ZEV mandate in 2023, the then-Conservative government noted that PHEVs do not deliver the cost and CO2 savings they are advertised with.

It pointed to “dramatic” differences between the performance of PHEVs in test cycles and what they deliver under real-world conditions.

In practice, less than a third of miles driven in PHEVs are fuelled by electricity, with petrol making up the rest. As a result, cost and CO2 savings from BEVs are three times larger than for PHEVs.

UN’s first Paris Agreement carbon credits face human rights and climate concerns

Published

on

Civil society groups have called for an investigation into the first carbon credits approved under a new UN mechanism, alleging the project is linked to Myanmar’s military junta – which the UN says is guilty of human rights abuses – and has “massively” overstated its climate impact.

The programme, which aims to cut emissions by distributing efficient cookstoves across Myanmar, received approval to issue around 650,000 carbon credits from the Article 6.4 Supervisory Body in February, in a landmark moment for the Paris Agreement’s carbon market. Only two projects have been given the green light by the mechanism’s regulator so far.

But two reports published last week, led by the Global Forest Coalition and Brussels-based NGO Carbon Market Watch, raised serious concerns about the project’s implementation in conflict zones where civilians have faced airstrikes and mass displacement as well as its emission-reduction calculations.

Project continued after military coup

Myanmar has been ravaged by a brutal civil war since the country’s military overthrew the democratically elected government in a coup d’état in February 2021. The military regime has attacked civilian populations, persecuted ethnic minorities and committed widespread sexual violence, among other serious human rights violations, the UN Special Rapporteur on the situation of human rights in Myanmar said in April.

The cookstove programme started in 2018 under the previous UN-run carbon offsetting scheme – the Clean Development Mechanism (CDM) – as a partnership between Myanmar’s Ministry of Natural Resources and Environmental Conservation (MONREC) and the Climate Change Center (CCC), a South Korean NGO, with investment from private South Korean firms.

    The project continued operating after the coup. For most of the period between 2021 and 2022 in which the issued credits were generated, MONREC was led by Colonel Khin Maung Yi, who was sanctioned by the European Union in 2021 for supporting the military regime, the Global Forest Coalition report said.

    CCC acknowledged engaging with government authorities after the coup but said this “should not be interpreted as political endorsement” of the junta. The South Korean NGO added that abandoning the programme when political circumstances changed “would not necessarily have been the most responsible outcome for the households involved”.

    Conflict prevents on the ground verification

    The Global Forest Coalition report raised particular concerns about the project’s implementation in Myanmar’s central Dry Zone, including Sagaing Region, an anti-junta resistance stronghold that has been most heavily affected by the conflict and routinely targeted by airstrikes and violent attacks. The region accounts for more than a third of Myanmar’s 3.8 million internally displaced people.

    The NGOs said that, in addition to ethical concerns about carbon credits being produced by the military government in an area actively affected by its attacks, this raises questions over the ability to effectively verify the climate integrity of the projects.

    Before carbon credits are issued, external auditors need to validate the claims made by project developers and confirm that the emission reductions claimed are correct. This process usually includes site visits to a representative sample of households to check how the improved cookstoves are being used.

    But, because of the “volatile political situation” in Myanmar, the auditing team was not able to leave the capital Yangon and could only speak to project participants remotely via Zoom, project documents show.

    “Due to ongoing armed conflict on the ground, the data currently used to justify carbon credit issuance in Sagaing by the Burmese military junta is unverifiable and highly likely fraudulent,” said Zaw Tuseng, founder and president of the Myanmar Policy Institute, which contributed to the report, in a written statement. “This demands an immediate suspension of credit transfers until a neutral, conflict-sensitive audit can be conducted.”

    “Exceptional circumstances”

    CCC told Climate Home News that, although it recognises that on-site verification is “generally preferable, particularly in complex operating environments”, the decision to opt for remote controls was not taken “as a discretionary shortcut, but as an approved alternative under exceptional circumstances”.

    The South Korean NGO added that it reviewed the feasibility of the project at community level “on an ongoing basis” and it “did not identify conflict-related incidents that directly affected project implementation activities in participating communities during the monitoring period”.

    A spokesperson for the UN climate change body told Climate Home News that, when site access is not possible, the UN carbon credit mechanism allows for “alternative verification approaches while still maintaining conservative assumptions and environmental integrity safeguards”. “These provisions ensure that crediting can only proceed where evidence is reliable,” they added.

    Contested methodology

    Carbon markets are seen as an important channel to raise money to help low-income communities in developing countries switch to less polluting cooking methods, both reducing CO2 emissions and improving air quality. But several cookstove offsetting projects have faced criticism from researchers and campaigners who argue that climate benefits are often exaggerated and weak monitoring can undermine claims of real emission reductions.

    The project in Myanmar uses a contested methodology developed under the earlier Kyoto Protocol that was rejected last year by The Integrity Council for the Voluntary Carbon Market (ICVCM), a watchdog that issues quality labels to carbon credit types, because it found it “insufficiently rigorous”.

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

    After transitioning from the CDM to the new mechanism, the project was required to apply “more conservative” assumptions to calculate emission reductions, which resulted in 40% fewer credits being issued, according to the UN climate change body.

    “The result is consistent with environmental integrity requirements and ensures that each credited tonne genuinely represents a tonne reduced and contributes to the goals of the Paris Agreement,” Mkhuthazi Steleki, the South African chair of the Article 6.4 Supervisory Body, which oversees the mechanism, said in February.

    Too many credits issued

    But Carbon Market Watch claimed in a second report last week that, despite the adjustment, the project is still likely to issue seven times more credits than its real climate impact justifies, comparing its calculations with values from peer-reviewed scientific literature.

    The biggest driver of the credit inflation, the group said, is the failure to account for “stacking” – the widespread practice of households using multiple stoves at the same time, including more polluting ones the project does not monitor.

    Peer-reviewed science considers a stacking rate of 68% a conservative assumption, but the methodology used by the Myanmar programme makes no allowance for it at all, the report said.

    CCC disputed those findings. In a written response to Climate Home News, it said the project was developed under methodologies approved within the UN climate framework and that external recalculations by researchers are not “determinative of the level of crediting achieved”.

    The credits are expected to be used primarily by major South Korean polluters to meet obligations under the country’s emissions trading system – a move that will also enable the government to count those units toward emissions reduction targets in its nationally determined contribution (NDC), the UN climate body told Climate Home News.

    Myanmar will use the remaining credits to achieve in part the goals of its own national climate plan under the Paris Agreement.

    “Over-crediting, at any magnitude, cannot be compatible with the climate ambition of a world striving to limit global warming to 1.5ºC,” said Isa Mulder, an expert at Carbon Market Watch.
