World leaders gathered in Paris this week to pledge to make 2024 the “pivotal year” for improving access to clean cooking.
At an International Energy Agency (IEA) summit attended on Tuesday by heads of state and ministers from 27 countries, a total of $2.2bn was pledged to boost uptake of clean cooking technologies.
The summit focused on improving access to clean cooking in sub-Saharan Africa, where nearly four out of five people still rely on open fires to prepare food.
Ensuring global access to clean cooking by 2030 could save 2.5 million people – mostly women and children – from premature deaths associated with breathing fire smoke, the IEA says. It could also save 1.5bn tonnes of CO2 equivalent (tCO2e), around the same as a year of global shipping and aviation emissions.
But while the case for achieving universal clean cooking is clear, questions remain over how finance should be leveraged and what kind of solutions should be pursued.
The conference featured speeches from a number of fossil-fuel executives, who argued that cookstoves using liquified petroleum gas (LPG) offer the quickest and “cleanest” solution for boosting cooking access.
This drew criticism from African commentators, who noted that fossil-fuel representatives actually outnumbered African women, who made up just 17% of the people at the summit.
The role that carbon offsets should play in helping to distribute clean cookstoves in Africa was also much touted by heads of state and industry representatives.
Academic research has found that the “carbon credits” issued by cookstove projects in the past have been “largely worthless”. But advocates told the conference that new guidelines could enable the development of “high integrity” credits for projects in Africa.
Carbon Brief attended the summit at the United Nations Educational, Scientific and Cultural Organization (UNESCO) headquarters in Paris and spoke to experts about what the new global pledge could mean for climate, energy, nature and gender goals.

How could clean cooking aid climate, nature and gender goals?
Around 2.3 billion people – close to a third of the global population – lack access to clean cooking facilities, relying instead on wood, kerosene or coal as their primary cooking fuel.
The number of people without access to clean cooking is declining in Asia and Latin America. But in sub-Saharan Africa, continued population growth means the number of people without clean cooking access is still increasing.
Household air pollution, mostly from the inhalation of cooking smoke, is linked to around 3.7 million premature deaths each year, the IEA says. In Africa, women and children, who spend the most time at home, account for 60% of early deaths related to smoke inhalation and indoor air pollution.
Ensuring global access to clean cooking by 2030 is a key component of goal seven of the Sustainable Development Goals.
According to IEA projections, meeting this target could save 2.5 million people – mostly women and children – from premature deaths associated with breathing fire smoke.
In sub-Saharan Africa, many women and children are burdened with collecting firewood for hours each day in order to prepare a meal. The IEA projects that universal access to clean cooking could save the average household nearly 1.5 hours a day, which would likely, in turn, increase female participation in schooling and employment.
In addition to this, the IEA estimates that universal access to clean cooking – achieved in the way their scenario suggests – could save a total of 1.5bntCO2e from a combination of reduced combustion emissions and avoided deforestation for firewood.
At the summit in Paris on 14 May, heads of state and high-level private-industry figures repeatedly emphasised the clear benefits of improving clean cooking access in Africa – with many admitting they had neglected the issue for too long.
In his opening remarks to the summit, Akinwumi Adesina, a former Nigerian agricultural minister who is now president of the African Development Bank Group, spoke candidly of his experiences growing up in a low-income neighbourhood without access to clean cooking.
“I don’t wear glasses just because I went to university,” he told the summit, explaining that, as a child, he spent years standing over fire smoke, which likely damaged his vision.
He told the story of a female friend that died in a kerosene accident after fetching the fuel for use in cooking. Her family could not afford to buy a gas stove.
“How can we let these things happen?” he asked the conference.
Many speakers emphasised that, compared to other parts of the energy sector, such as heavy industry, improving access to clean cooking is “solvable”, as the technology needed is already available at a relatively low cost.
The IEA estimates that $4bn will need to be leveraged annually until 2030 in order to achieve universal clean cooking access. By comparison, total clean energy technology investment will need to reach $4tn per year by 2030 to meet net-zero, IEA says.
The clean cooking summit itself raised $2.2bn for clean cooking, the IEA said. IEA executive director Dr Fatih Birol promised that his agency would track where each penny was spent and reveal the results in a year.
Despite the new financial pledges and renewed focus, some lamented the lack of inclusion of African women at the conference.
Writing for African Arguments, the Ugandan climate activist Vanessa Nakate noted that the number of fossil-fuel executives outnumbered African women, who made up just 17% of the people in attendance.
One male session chair even cracked a joke about the lack of women speaking at the summit, telling the audience that the IEA should be pleased that clean cooking will no longer be viewed as “just a women’s issue”.
Later on at the summit, Graça Machel, a former Tanzanian education minister and deputy chair of the Elders, a group of global leaders started by former South African president Nelson Mandela, appealed for African women to be directly involved in high-level decision making on clean cooking. She told the conference:
“We need to build the capacity of women themselves so they aren’t just recipients. African women – we want to be investors, entrepreneurs, managers and customers. Any policy has to have the face of women, taking into account the magnitude [of our presence]. In our countries, we are millions. Clean cooking is about African women.”
What are the solutions on offer for clean cooking in Africa?
More than 238 million people in sub-Saharan Africa live in informal housing, making the distribution of clean cooking technologies challenging.
Traditional “unclean” cooking involves a pot perched on top of a simple fire burning wood or waste products, or a kerosene dispenser.
According to the IEA, the main options for clean cooking include:
- Improved biomass stoves: An enclosed stove that burns solid fuel, but keeps heat from escaping and improves combustion, thereby reducing polluting smoke.
- E-cooking or electric stoves: Primarily hot plates, induction stovetops, rice cookers or electric pressure cookers that are plugged into an electricity source, which can come from renewable power.
- LPG stoves: A fossil-fuel burner that uses a mixture of propane and butane distributed in large pressurised cylinders.
- Biodigesters: A large vessel where organic matter (animal manure, agriculture residues or food waste) is decomposed into biogas. This biogas is then used in a burner-type stove.
- Ethanol: A simple burner that attaches to a small canister containing alcohol fuel made from crops, such as corn or sugar, that has been fermented and distilled.
- Gas stoves: A burner that uses fossil-fuel gas typically delivered to customers via distribution pipelines.
The IEA infographic below demonstrates how each of these methods work.
At the summit, fossil-fuel executives from companies such as TotalEnergies, Shell, Eni, Indian Oil and Equinor were keen to stress the role that LPG cookstoves should play in providing clean cooking access in Africa.
Patrick Pouyanné, chairman of the board and chief executive officer at TotalEnergies – one of the fossil fuel companies behind the controversial East African oil pipeline project – told the summit that his company will invest more than $400m in the development of LPG for cooking by 2030.
Eirik Wærness, senior vice president and chief economist at Equinor – a key funder of the controversial Rosebank oil field in UK waters – boasted that his company already supplies 10% of India’s LPG. He told the conference:
“We should not let the best – which is renewable energy – stand in the way of the good [LPG]. We will do all that we can to provide LPG – and also LNG [liquified natural gas] – as a viable, clean fuel.”
The IEA’s scenario for achieving universal clean cooking access sees a key role of LPG cookstoves. It notes that, in the last decade, 70% of people who gained “clean” cooking access globally did so through LPG.
In its scenario, LPG remains the “primary solution to deliver clean cooking access”, representing nearly half of new household access in 2030.
Below, an IEA graphic breaks down the numbers of households gaining access to different types of clean cooking in 2022 (left) and how its scenario expects households to gain access from 2023-2030.
At the sidelines of the summit, Carbon Brief spoke to Dr Donnee Alexander, chief science officer for the Clean Cooking Alliance, a UN-backed NGO which helped to coordinate the summit.
Asked about whether a focus on LPG cookstoves over renewable-energy methods could risk locking African nations into further fossil-fuel dependency, she responded:
“I think Africa should be able to transition however they so desire. Because they have no energy. For me to say, ‘you need to transition in a certain way’, when a woman is cooking over an open fire and dying prematurely because she’s experiencing smoke inhalation every day of her life, who am I to say that she should not be transitioning to a much cleaner option compared to the baseline?”
But several African commentators reject the idea that fossil fuels are the key solution to Africa’s clean cooking crisis.
In her commentary on the summit, Nakate says:
“Natural gas is not clean…burning LPG or methane at home emits nitrogen dioxide, carbon monoxide and benzene, all [of] which can potentially trigger respiratory complications, including childhood asthma…Instead of trying to make gas affordable, the summit should seek to unlock investments that establish and scale ambitious and people-centred energy programmes. This is the most reasonable way to deliver decentralised energy to communities on the continent.”
Her thoughts are echoed by Mohamed Adow, founder and director of the Power Shift Africa thinktank in Kenya.
In a statement, he said there is “no evidence” that gas is the solution to providing clean cooking access in Africa, adding:
“What we need is a woman-centred approach that puts their needs first, not those of a greedy private sector looking to make profits. Rather than subsidies for private companies, that money would be better used investing in high efficiency, low-cost electric cookers for Africans.”
While most of the speakers at the summit focused on LPG, there was some recognition that renewable energy could be a way forward for providing clean cooking.
Stanlake Samkange, assistant executive director at the World Food Programme, said that his organisation had traditionally focused on supplying cleaner fuel stoves, but that “2024 is a departure”. He added:
“We are not just focusing on fuel efficient stoves but clean cooking…We are looking at electronic stoves and e-cooking. In Madagascar, we are looking to link that to solar panels.”
How will improved access to clean cooking be financed?
The IEA estimates that $4bn will need to be leveraged annually until 2030 in order to achieve universal clean cooking access.
The clean cooking summit raised $2.2bn from public and private sources. This included new pledges from the EU, France, Denmark, the US, the UK and firms, including fossil-fuel companies.
It follows on from a high-level clean cooking event at the COP28 climate summit in Dubai, where the African Development Bank pledged to allocate a separate $2bn for clean cooking over the next decade.
At the Paris summit, Birol pledged that the IEA will closely monitor where the finance is spent and reveal the results in a year.
Throughout the conference, heads of state, ministers and company CEOs made it clear that they saw clean cookstove carbon-offset projects as key for leveraging finance and distributing new technologies in Africa.
Offsetting involves developed nations or companies paying for projects that distribute clean cookstoves, allowing them to then claim they have reduced their own emissions by paying to cut carbon in another country. (For a full breakdown, see Carbon Brief’s carbon offsets explainer.)
Stephanie Mbombo, presidential special envoy for the new climate economy for the Democratic Republic of the Congo, said that her president saw carbon offsets as the “key driver” for access to clean cooking, telling the summit:
“[With] carbon credits, we will save the world, but we will also save ourselves.”
The CEOs of clean cookstove carbon-offset companies were invited to speak alongside senior political figures and made bold claims about how they could play a pivotal role.
“With carbon credits, it’s solved, it’s done,” said Peter Scott, the CEO of the cookstove company BURN Manufacturing.
This sentiment was echoed in the declaration issued from the summit.
It said that participants “acknowledge the significant role that carbon credits and climate finance have already played in scaling clean cooking efforts, recognising the potential for further expansion of this support”.
But academic research has found that clean cookstove carbon-offset projects are “largely worthless” in emissions reductions terms.
A study in the journal Nature Sustainability found that nine in 10 of the 96m cookstove credits certified by leading carbon registries do not avoid the emissions they claim.
What is more, investigations by journalists, including at Climate Home News, have uncovered serious faults with clean cookstove projects, such as faulty stoves being distributed without communities being given access to repairs or replacements.
Gilles Dufrasne, policy lead at Carbon Market Watch, a watchdog of carbon offsets, told Carbon Brief that cookstove projects have “perhaps” been the least successful at achieving emissions reductions out of all types of carbon-offset projects. He added:
“This is a case of projects that very likely have significant positive impacts for sustainable development, and likely also positive climate impacts, but where the quantification of these impacts is extremely shaky. Most projects issue many more credits than they should, and that’s a problem if countries use it to meet their nationally determined contributions – as this [clean cooking summit declaration] suggests they could.”
Acknowledging the need for more “high integrity” cookstove credits, the conference saw the Clean Cooking Alliance launch new “principles for responsible carbon finance in clean cooking”.
Alexander told Carbon Brief the goal of the principles was to “address the challenges in the carbon market to ensure that we have both higher integrity but also higher demand”.
She said that the new principles could bring about tangible ways of improving the outcomes of cookstove carbon-offsets projects:
“We’re saying let’s measure reduction in fuel use [from distributing clean cookstoves], utilising standard methodologies. Or let’s have digital monitoring and verification so we know exactly when the stove is used. Things like that start to bring more integrity into the system.”
Dufrasne added to Carbon Brief that, with current projects offering little guarantee that promised emissions reductions will be achieved, there is a risk that the sale of more carbon credits to developed nations will lead to these countries reducing their emissions by less than if they had invested in alternative climate measures:
“Getting countries and companies to pledge finance to a fund, which then finances cookstove projects – with or without credits – is likely to be a better way.”

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.

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.

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.

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.
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.
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.”
