At Cop26 in Glasgow hundreds of governments and private institutions joined together in a series of pledges promising ambitious goals on methane reduction, forest protection and the shift of finance away from fossil fuels.

Nearly two years on, Climate Home News looks at how these commitments are holding up to the test of time.

METHANE PLEDGE

WHAT: Reduce human-made methane emissions by 30% between 2020 and 2030. Cutting the amount of methane present in the atmosphere is important because it is a much more powerful greenhouse gas than carbon dioxide despite having a shorter lifespan.

WHO: 104 countries, led by the US and the EU, signed up to the pledge when it was first announced at Cop26 in Glasgow. The number of signatories has since risen to 150. However, they only represent about half of global methane emissions as China, India and Russia – three of the world’s top four emitters – have not joined the coalition.

HOW IT IS GOING: The raw figures paint a fairly grim picture. Since Cop26, the concentration of methane in the atmosphere has kept rising fast and it is now more than two and a half times its pre-industrial level.

Over half of the emissions come from human activities, like fossil fuel extraction, farming and landfills, with the rest caused by natural sources. Under current trajectories, total human-made methane emissions could rise by up to 13% between 2020 and 2030 – the pledge’s timeframe.

Targeting the oil and gas sector is seen by many as the easiest and fastest way to bring down emissions in the near term. Experts say existing technologies already provide cheap and effective ways to plug leaky infrastructure like pipelines and gas storage tanks.

However, the technological developments have not yet been converted into real, widespread action. According to the International Energy Agency (IEA), methane emissions from oil and gas remained “stubbornly high” in 2022 even as the energy companies’ bumper profits made actions to reduce them cheaper than ever. “There is just no excuse”, the IEA chief Fatih Birol commented.

Raft of initiatives

But judging the pledge’s progress on current numbers only tells half the story, argued Jonathan Banks, global director of the methane programme at the Clean Air Task Force (CATF). “Emissions are not going to turn around immediately,” he told Climate Home. “If you look at the work going into the pledge, building the funding and technical resources to bring emissions down, I think it could potentially be on track for success”.

A series of initiatives have been set up to help countries deliver on the pledge. The UN’s Climate and Clean Air Coalition (CCAC) is helping over 30 developed and developing countries to establish plans to achieve the 2030 target.

Canada has set out a strategy that it expects to reduce domestic methane emissions by “more than 35%” by 2030, compared to 2020.

The Global Methane Hub (GMH), a philanthropic organisation, is also supporting signatories of the methane pledge with technical assistance and funding. Carolina Urmeneta, a director at the GMH, told Climate Home News that over the last year, the group has focused its work on developing systems to monitor methane emissions rates from oil and gas and landfill installations using satellites.

She said reaching the 2030 target “is possible and cost-effective, but it is not easy. We need to improve data transparency and increase funding for projects with methane targets.”

Regulations drive

Some progress has also been made on the regulatory front. The USA introduced new rules to address methane emissions caused by oil and gas companies through the Inflation Reduction Act. Using a carrot-and-stick approach, it provides $1 billion in public subsidies to take action, while charging a fee for excessive emissions.

In May the European Parliament agreed on tougher measures to tackle methane emissions in the energy sector. The approved text calls for binding emission reduction targets, stronger obligations for fossil fuel operators to detect and repair leaky infrastructure and the application of the same measures to exporting countries outside of the bloc.

While the final rules are still being negotiated with the EU’s national governments, CATF’s Banks believes they could have a “huge global impact” if introduced in their current form. “The methane emissions associated with the gas Europe buys from the rest of the world is quite large, so such measures could really drive some change”.

New announcements are expected at Cop28 in Dubai, after the summit’s president Sultan Al Jaber set the phaseout of methane emissions in oil and gas by 2030 as one of his priorities. “More than 20 oil and gas companies have answered Cop28’s call,” he said this week. “And I see positive momentum as more are joining”. But the UAE has been accused of double standards as it failed to report methane emissions to the UN for a decade, as the Guardian reported.

While it has not signed the pledge, China is expected to announce its long-awaited methane plan at Cop28.

FOREST PLEDGE 

WHAT: End and reverse deforestation by 2030. Country leaders pledged to conserve forests, tackle wildfires, facilitate sustainable agriculture, support indigenous populations and “significantly” increase the provision of finance towards achieving those goals.

WHO: More than 140 countries joined the coalition. Signatories of the pledge – including large forest nations like Brazil, Indonesia and the Democratic Republic of Congo – cover around 90% of the world’s forests. But major G20 powers such as India, South Africa, Saudi Arabia and rainforest nations like Bolivia and Venezuela did not join the group.

HOW IT IS GOING:  Countries remain off track to reach the goal of the Glasgow pledge and end deforestation by 2030, according to an assessment done by a coalition of NGOs.

Across the world, tree loss recorded in 2022 was 21% higher than the level needed to be on course to reach zero in seven years’ time, the report said.

In fact, the situation is getting worse. Global deforestation grew 4% last year, wiping out 6.6 million hectares of forest, according to the study. That’s a tree-covered area nearly as big as Ireland disappearing in one year.

“The world’s forests are in crisis. All these promises have been made to halt deforestation, to fund forest protection. But the opportunity to make progress is passing us by year after year,” said Erin Matson, a lead author of the Forest Declaration Assessment.

Saving the Three Basins means stopping fossil fuel expansion

There are important regional differences, however. While tropical Asia is faring better, with Indonesia and Malaysia on track to hit their targets, Latin America and the Caribbean are farthest off track.

The election of President Lula da Silva in Brazil has led to a reversal in the skyrocketing deforestation rates in the country, which hosts most of the Amazon rainforets.

But efforts to create a regional forest protection coalition have failed. At the Amazon summit in August, eight South American countries failed to agree on a pledge to end deforestation by 2030 following opposition from Bolivia and Venezuela.

While it included a larger number of countries, the Cop26 commitment was not entirely new: it repeated promises previously made in the 2014 New York Declaration on Forests, which by then had already failed to achieve some of its core targets.

Keen to avoid the same fate, self-declared “high ambition” countries launched a new initiative designed to deliver the pledge.

“High ambition” efforts

Chaired by the USA and Ghana, the Forest and Climate Leaders’ Partnership (FCLP) has promised to spur global action and provide accountability.

Only a fifth of the original 140 signatories have joined the group so far, with Russia and Indonesia among the most notable absentees.

Christine Dragisic, who leads the forest team at the US State Department, said the goal is to create a “high-level community” that brings together governments, indigenous people, philanthropies, civil society and the private sector to drive action forward and hit the 2030 target.

“Can we do it? Yes. Is it going to be hard? Definitely. Does it require everybody to be at the table? For sure”, Dragisic told Climate Home.

Since its launch last year, the FCLP has worked on a number of initiatives offering technical and financial solutions to forest nations, looking at the role of carbon markets and the forest economy in averting tree loss.

Finance gaps

As with most climate actions, however, it ultimately comes down to the question of money. “The delivery of climate finance is very important to achieve a lot of these targets and that is still very much lacking”, Roselyn Fosuah Adjei, director of climate change at Ghana’s forestry commission and co-chair of the FCLP, told Climate Home.

“The kind of finance we need is not finance for today or tomorrow, it’s finance for yesterday. We are already behind schedule. If it gets delivered fast there’s lots that we can do to close the gap that is now quite wide,” she added.

The Cop26 pledge was accompanied by a commitment from a group of rich nations to provide $12 billion in forest-related climate finance between 2021 and 2025. The money should be channeled to developing countries enacting concrete steps to halt forest loss.

The donor countries reported last year that they had provided $2.6 billion – over a fifth of the target amount – in 2021. They are expected to provide an update at Cop28.

INTERNATIONAL FOSSIL FINANCE PLEDGE

WHAT: End new direct public support for the international unabated fossil fuel energy sector by the end of 2022, except in limited and clearly defined circumstances that are consistent with a 1.5°C warming limit and the goals of the Paris Agreement.

WHO: 34 countries and five development banks – predominantly from wealthy cuontries – signed up to the pledge at Cop26. These included the G7 nations – with the exception of Japan – and most EU member states.

HOW IT IS GOING: Among the signatories that give lots of money to the energy sector, the vast majority have introduced policies in line with the promise made in Glasgow.

The United Kingdom, France, Denmark, New Zealand, Canada, Finland and Sweden have stopped providing loans and guarantees for oil and gas extraction and processing overseas through their export credit agencies.

Their actions have shifted at least $5.7 billion per year in public finance out of fossil fuels and into clean energy, according to analysis by Oil Change International and E3G.

On the other hand, however, the USA, Italy and Germany have continued funding international fossil fuel projects in 2023 in breach of the pledge.

They were supposed to stop funding foreign fossil fuels by December 2022. But since then, they collectively approved over $3 billion in financial support to oil and gas overseas programmes.

Most of the funding comes in the form of state-backed guarantees provided by export credit agencies. These products limit the risk taken by companies selling services and goods in other countries, influencing investment.

Among the projects receiving backing from the US and Italy was the expansion of an oil refining facility in Indonesia’s Borneo.

The US Export-Import Bank justified its backing of the project by claiming it would allow Indonesia to reduce its reliance on imported fossil fuels. The Italian agency did not provide a motivation for the decision.

Germany and the US have also poured hundreds of millions of dollars into projects aiming to boost the production and trade of liquified natural gas (LNG), which has been more sought after since Russia invaded Ukraine and Europe cut back on Russian gas.

Political splits and carve-outs

In the US, efforts to comply with the Glasgow pledge have caused a split among senior officials in the Biden administration and in the federal agencies charged with disbursing the money, as Politico revealed.

The White House has drafted guidance underpinning the investments - without making it public -, but the final decisions are made by agencies like the US Export-Import Bank (Exim).

“It is a struggle to get US Exim to comply, so far they’ve ignored the Cop26 commitment”, says Nina Pusic from Oil Change International. “It will require a lot of political weight from the Biden administration and Congress.”

Indonesia delays coal closure plans after finance row with rich nations

Italy looks likely to keep funding fossil fuels overseas for years to come. Its policy guidance lays out a "gradual dismission of public support to new requests of fossil fuel projects", seeing support for gas extraction and production run into 2026. Oil processing and distribution projects should be excluded from the beginning of next year.

But Italy has also carved out a wide range of exceptions that allow its export credit agency to keep greenlighting support for fossil fuel projects on "national energy security" and "energy efficiency" grounds.

Germany's main export credit agency has just introduced this month new policies restricting support for fossil fuel projects. However, it allows for financing the development of new gas fields and related transport facilities until 2025 when justified by "national security and in compliance with the Paris Agreement targets".

Investment in new coal, oil and gas production is regarded as incompatible with limiting global warming to 1.5C, according to the International Energy Agency (IEA) and a large number of climate scientists.

"Germany has a vast amount of fossil fuel transactions pending approval", says Oil Change International's Pusic. "The success of the new policy will be judged on the decisions made on those projects".

GLASGOW FINANCIAL ALLIANCE FOR NET ZERO (GFANZ)

WHAT: Commit to achieving net zero emissions by 2050 at the latest by aligning their portfolios and investment practices with the goals of the Paris Agreement.

WHO: Over 650 institutions across the financial sector, including banks, insurers, asset owners, asset managers, financial service providers, and investment consultants. Gfanz members represent 40% of global private financial assets. They are grouped together under eight independent net-zero financial alliances focused on specific branches of finance.

HOW IT IS GOING: It is not easy to gauge the progress of a wide-ranging initiative with loosely defined targets and a constellation of constituent parts.

Above all, the mere fact that the alliance still exists at all is a first - albeit limited - marker of success, after an especially tumultuous year.

The prospect of ending up in legal hot waters in the US, where Republicans have driven an anti-climate investment backlash, has dampened the enthusiasm of many leading signatories. The result is that parts of the alliance have been hemorrhaging members, while other components have resorted to watering down their requirements to assuage concerns.

Troubles started brewing in mid-2022 when a group of leading US banks threatened to pull out over fears of being sued because of having decarbonisation policies imposed by external parties. That's after US Republican politicians had accused financial institutions of breaching antitrust rules by grouping together in a climate cartel that limits opportunities for investors.

A month later, in October 2022, Gfanz dropped a key requirement for its members to sign up to the UN Race to Zero initiative - a verification body for corporate and financial sector pledges - which had been seen as a way to prevent greenwashing.

Heading for the door

Those US banks eventually ended up staying in but, despite the less stringent criteria, other influential members began heading for the door in droves soon after.

Vanguard, one of the world's biggest asset managers, quit the Net Zero Asset Managers' initiative - part of Gfanz - saying it wanted to "provide clarity to investors" and "speak independently on matters of importance" to them.

But it's the insurers' coalition, known as NZIA, that has suffered the biggest - nearly fatal - wounds. The group has lost nearly two-thirds of its members since the start of the year, with leading firms like Allianz, Zurich, Munich Re and Lloyd's of London throwing in the towel.

Again a major driver for the mass exit was a letter written in May by 23 Republican attorney generals accusing signatories of advancing "an activists climate agenda" with "serious detrimental effects on the residents" of their states. The spark for this was the alliance's initial obligation to its members to set emission reduction targets by the end of July.

Staring at the real prospect of shutting down, the insurers' alliance again watered down its requirements, becoming effectively toothless.

To triple renewable energy, the Global South needs finance

"NZIA member companies have no obligation to set or publish targets", wrote the UN Environment Programme (Unep) - convener of the initiative -  in a clarification letter. "Each company who chooses to be a member of the NZIA unilaterally and independently decides on the steps on its path towards net zero."

Meanwhile, GFANZ says its members have submitted over 300 interim targets "representing clear progress in implementing commitments" to divert finance in line with net zero goals.

But while plans have been announced, many GFANZ members are also being accused of not putting their money where their mouth is. 161 members of the coalition have collectively invested hundreds of billions of dollars into the expansion of the coal, oil and gas industries since they joined the group, according to research by campaigning group Reclaim Finance.

Every country needs a model to help optimise its energy transition

Published

on

Claver Gatete is Executive Secretary of the UN Economic Commission for Africa. Jason Veysey is Energy Modeling Program Director and Senior Scientist at the Stockholm Environment Institute. Lisa Sachs is Director of the Columbia Center on Sustainable Investment at Columbia University.

The case for global energy transition has rarely been clearer. The closure of the Strait of Hormuz earlier this year exposed the cost of unplanned, fossil-dependent systems, while the falling cost of renewables, the rising penetration of electric vehicles, and the growing value of demand flexibility have made the direction of travel obvious. The benefits of a clean, secure, integrated system are no longer in dispute. What remains unclear is how to build it.

Countries around the world have called for faster renewable energy deployment and alternative energy arrangements. A secure, affordable, resilient, decarbonised system requires specific investments in specific places in a specific sequence, optimised across sectors and borders. But very few governments have the analytical foundation to translate those imperatives into investment.

The two instruments that are supposed to determine investment priorities for decarbonisation – Nationally Determined Contributions (NDCs) and country platforms – cannot answer the most basic question facing any country undertaking an energy transition: what should the energy system look like?

    To close this gap, every country needs a bankable, economy-wide optimisation model for its energy system. A model is not a plan, but it can help answer the critical question of what the future energy system should look like. It shows how optimal scenarios vary as assumptions and policies are adjusted, calculates investment requirements and sequencing, and quantifies how system costs are affected by assumptions, policies, and exogenous variables like trade policy and financing terms.

    Tool for efficient investment

    Optimisation is a simplified way of simulating an energy system, but it can be an extremely powerful tool for moving energy planning from reactive (how do we manage the disparate actions in the energy system?) to intentional (what energy system underpins our national objectives?). A model can show how optimal scenarios vary as assumptions and policies are adjusted, and how investment requirements are quantified and sequenced.

    Optimisation models can treat the energy system and the sectors it serves as an integrated whole, optimising across sectors and projects in ways that can be mutually reinforcing. If considered independently, growth in industrial demand, transport electrification, and digital infrastructure can add stress to the energy system. But an optimised plan can arrange these and other changes in an efficient, synergistic way.

    Two to tango: How governments can unlock private investment for national climate goals

    New load can be added where low-cost power is available; industrial customers can ensure the viability of investments in energy supply; electric vehicle charging policy can smooth load curves and reduce costs for all consumers.

    Additionally, optimisation modeling can also change the financeability of investments. Taken alone, each project faces uncertainty about the rest of the system, which raises the cost of capital and causes projects to stall or unwind after contracts are signed. A coherent, optimised plan makes visible the coordination that private capital would otherwise have to bet on: identified offtake, sequenced and committed transmission, contracted power supply, and so on.

    What COP31 and COP32 should do

    The upcoming COPs in Turkey and Ethiopia can shift the center of gravity of international climate cooperation from fragmented commitments to planning. Three moves are urgently needed.

    First, optimised, economy-wide, long-term energy system planning must be the foundation on which any meaningful NDC, country platform, or finance commitment rests. NDCs are typically drafted by environment or single-line ministries, with limited cross-sectoral input from ministries of energy, finance, and planning. They contain targets, derived from sectoral strategies or national commitments, not from an analytically grounded picture of what the energy system should look like and what investments would make it work. Country platforms are generally a portfolio of investments assembled from existing project pipelines, rather than derived from a system-level analysis of what an optimised, decarbonised energy system would require.

    Second, recognise regions as a key planning unit. Modern integrated energy systems are inherently regional. Renewable endowments are unevenly distributed; balancing variable supply across borders lowers aggregate cost, reduces redundant backup capacity, and unlocks economies of scale no individual nation can achieve. Many energy investments in Southeast Asia, East Africa, Southern Africa and Central Asia may only be financeable in a regional context. Assessing domestic infrastructure without regional optimisation perpetuates the perception that decarbonisation is more expensive than it is.

    COP31 leaders unveil global targets, with spotlight on electrification

    Third, finance the planning capacity. A coordinated commitment by multilateral development banks, bilateral donors, and philanthropic partners to help every region and its constituent countries develop and maintain their own modelling capability, with open-source tools and regional analytical hubs, would close the most consequential gap in the current architecture. The cost is small relative to current spending on country platforms, failed project preparation, and misallocated infrastructure investment.

    This includes supporting regional institutions such as the ASEAN Centre for Energy, the African Energy Commission, regional power pools, and the Latin American and Caribbean Energy Organization to determine what optimised regional systems require. Country-by-country pledging, repeated at every COP, will not deliver what meaningfully integrated systems can.

    The 2026 energy crisis made the cost of unplanned, fossil-dependent systems newly visible. That window of clarity will close. The international community should seize the moment to build the planning foundation that has been missing for thirty years, rather than commissioning another round of NDCs or pledges, striving for outcomes neither was designed to deliver.

    Explainer: How the ‘super El Niño’ will reshape the world’s weather

    Published

    on

    The world is currently experiencing what is expected to become the strongest El Niño on record – dubbed a “super El Niño” by many.

    El Niño is the warm phase of a recurring climate pattern in the tropical Pacific that releases heat from the ocean into the atmosphere.

    This temporarily raises global temperatures and reshapes rainfall and extreme weather around the world – impacting the lives of billions of people.

    The current El Niño event began in June and is expected to last into 2027.

    El Niño is part of a wider climate pattern called the El Niño-Southern Oscillation (ENSO) cycle.

    The ENSO cycle also has a cool phase, known as La Niña, as well as a “neutral” phase. El Niño and La Niña events typically last between nine and 12 months, but can go on longer.

    Below, Carbon Brief explains how the ENSO cycle works, its impacts on extreme weather and global temperatures and why this El Niño event is projected to be the most intense since records began.

    Analysis: The two largest reservoirs in the US have hit record-low levels

    Published

    on

    The second-largest reservoir in the US reached a record-low water height on Saturday – just days after the country’s largest reservoir broke its own record. 

    Both Lake Mead and Lake Powell are located on the Colorado River.

    They provide water for populations across seven US states in the south-western US, with around 40 million people getting some or all of their municipal water from the Colorado River.

    The river also provides water for around 5.5m acres (22,258 square kilometres) of farmland across Colorado, Arizona, California and the other states in the river basin.

    Experts tell Carbon Brief that climate change, population growth and over-consumption are all contributing to the current record-low levels of the reservoirs.

    Record lows

    At full capacity, Lakes Mead and Powell can hold a combined 68 cubic kilometres of water – enough to supply all household consumption in the contiguous US for nearly 1.5 years. However, the water level in both reservoirs has been declining for decades.

    The chart below shows the water level of Lake Mead, in metres above mean sea level. The reservoir, which began to fill in 1935 following the construction of the Hoover Dam, has a “full pool” maximum capacity of 347.60 metres. The water level in Lake Mead reached a record low of 317.11 metres on 7 August.

    Lake Mead, the larges reservoir in the US, reached record-low water levels in early August.

    The following chart shows the water level of Lake Powell, in metres above mean sea level. Lake Powell’s full-pool level is 1,127.76 metres.

    While the reservoir reached its maximum capacity several times in the 1980s, it has not done so since. On 15 August, the water level in Lake Powell was recorded at a new record-low of 1,072.87 metres.

    Lake Powell, the second-largest reservoir in the US, reached record-low water levels in mid-August

    Both reservoirs have continued to decline in the days since breaking their respective records. The downward trend will largely continue in both lakes until next spring, when the snowpack in the mountains of the Upper Colorado River Basin begins to melt, says Dr Jack Schmidt, a senior research scientist at Utah State University’s Center for Colorado River Studies. He tells Carbon Brief:

    “The big dilemma of the moment is that we’re only in the middle of August, and we have no assurance of what the coming winter will be. The only thing we can be sure of is that we will be depleting overall total basin reservoir storage from now until, roughly, early April.”

    Compounding factors

    The record lows across the two reservoirs are the result of several compounding factors, experts tell Carbon Brief.

    Since the turn of the 20th century, the amount of water flowing along the Upper Colorado River has declined by about 20%. Research suggests that half of this decline can be attributed to human-induced climate change.

    Most of the river’s streamflow comes from the snowpack of the Upper Colorado River Basin, which stretches across five western US states but is primarily located in Colorado and Utah.

    This region has been gripped by a historic “megadrought” for more than a quarter of a century. Nearly half of the megadrought’s intensity over 2000-18 is attributable to climate change, according to a 2020 study.

    At the same time, the increasing population in the US south-west has put added pressure on the Colorado River’s water supply. The number of people obtaining some or all of their water from the Colorado system has grown by 15 million (around 60%) since 1992.

    Schmidt tells Carbon Brief:

    “There’s an ultimate cause of the present water crisis, and there’s a proximate cause. The ultimate cause is a warming climate, a warming planet and a pretty clear correlation between warming conditions and decreased runoff in the Colorado River Basin.

    “The proximate cause is that in this messy democratic republic of ours, big policy decisions that match the variability of the climate occur painfully slowly – with intense political negotiations – and only incrementally.”

    On 31 July, the US Bureau of Reclamation, which manages water resources in the western US, released an environmental impact statement on its proposed post-2026 strategy for managing Lakes Powell and Mead. The strategy itself has not been released yet.

    Schmidt notes that the statement does appear to give the Bureau flexibility to “respond to crisis” by reducing the delivery of water to several states. However, he adds:

    “They acknowledge it won’t work if we just stay critically dry, and of course every climate model for the 21st century, especially with a continually warming planet, says that that’s exactly what’s going to happen.”
