The Russian government’s campaign for endorsement of “transitional fuels” succeeded at the Cop28 climate talks in Dubai.
Russia, the world’s second biggest gas producer, told the United Nations back in February that “natural gas as a transitional fuel… can be used for [emission-cutting] purposes” and this should be recognised at Cop28.
While the final Cop28 agreement does not specifically mention gas, it “recognizes that transitional fuels can play a role in facilitating the energy transition while ensuring energy security”.
It also calls on governments to transition away from fossil fuels in their energy systems so as to achieve net zero by 2050.
Diann Black-Layne from Antigua and Barbuda told the closing meeting of Cop28 that the “transitional fuel” language “is a dangerous loophole”. Coal, oil and gas are all fossil fuels and “we need to transition away from them,” she said.
But Barbados’s climate envoy Avinash Persaud later told Climate Home: “If you actually think about transitioning grids, transition fuels would help to transition with the lowest emissions. You can’t flip a switch and so in the mean time half switch. The challenge is to make sure that the slip road doesn’t become a parking lot.”
Persaud said that “more than a few” countries had supported the language “at some level and at varying degrees”. Another negotiator agreed it “wasn’t just Russia”.
Last-minute addition
Ahead of Cop28, governments and other organisations told a UN panel what they wanted to do to put the world on track to meet its climate goals, in a process known as the global stocktake.
A team of technical experts summarised all the submissions in October. The head of UN climate change, Simon Stiell, called for a “course correction”.
The technical summary included a line which called on governments to “recognise role of natural gas as an efficient transitional fuel”.
At Cop28, the UAE Presidency put together a 27-page document which included the language which made it into the final text, dropping the mention of gas but referring to “transitional fuels”.
Like many other parts of this document, it included an alternative option of no text. Three days later, after talking to governments, the UAE Presidency dropped it from their next version of the Dubai deal.
With all the attention on the broader issue of fossil fuel phase-out, this language was little noticed or commented on – either in the press or by negotiators.
It stayed off the radar until the scheduled end date for Cop28, 12 December. It appeared in a draft text, according to a source who saw the text, time-stamped 8pm that night.
But some negotiators didn’t see it until the text was published at 7am the following morning. Four hours later, the closing plenary meeting began and within minutes it had been approved.
‘An honest paragraph’
The strongest supporters of anti-fossil fuel language at Cop28 were developed nations, particularly the European Union, and small islands.
But on gas, developed countries did not want to resist, and small islands were still in a separate meeting room discussing the text when the decision was made.
Speaking to press shortly afterwards, German foreign minister Annalena Baerbock said the EU delegation had not had much time to discuss the text.
But, she said through a translator, “for me it is really an honest paragraph”. She said Germany and the EU have been accused of hypocrisy at previous Cops for continuing to use gas while asking other countries to move to renewables.
“We wanted to show that this does not happen from one day for another but it will happen slowly, slowly, slowly,” she said. Gas is “a bridge”, she said, and “every bridge has an end”.
Kaveh Guilanpour, from the Center for Climate and Clean Energy Solutions, said he’d rather the language had not been there “but in many ways its consistent with what lot of countries and regions are actually doing”.
The day before Cop28 closed, Brazil auctioned 193 oil and gas blocks. On the day it closed, the Italian export credit agency lent €400m ($436m) to a firm to supply Italy with gas. The day after, the board of a European public bank decided to keep lending to gas pipelines and power plants.
Small islands not there
The negotiating group for 39 small, developing island states (Aosis) was most likely to object to that language.
But, having seen the final text at 7am, when the plenary started they were still frantically discussing whether to support it or not.
As they entered the room with their comments on the text in hand, the room was already standing to applaud Cop28 president Sultan Al-Jaber’s announcement that it had been adopted.
Their lead negotiator Anne Rasmussen from Samoa took the microphone to say she “was a little confused about what happened”.
Delivering her prepared remarks, she said that because of the transitional fuels language – and other issues – that the “course correction has not been secured”.
“We have made incremental advancements over business as usual when what we really needed is an exponential step change,” she said.
To a standing ovation, she said the text includes a “litany of loopholes” for carbon capture and on the removal of fossil fuel subsidies.

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.”
