Carbon credit certifiers from the much-criticized voluntary market could be the big winners of a failure to strike a deal on the exchange of offsets between countries at Cop28, experts told Climate Home.
Talks over Article 6.2 of the Paris Agreement – allowing for bilateral deals – collapsed in Dubai following a bitter fight over integrity between the European Union and the United States.
But willing countries can still move ahead with agreements in a vacuum that is increasingly being filled by independent certifiers from the voluntary market. Some observers are raising questions on whether they are fit for purpose.
Transatlantic fight
When the EU led a push at Cop28 for tighter controls over the bilateral exchange of carbon credits, one of its main goals was to restrict the role of operators from the voluntary carbon market.
In the year leading up to the summit, criticism of the market, which sells offsets mainly to corporate emitters, intensified. The climate credentials and the social and environmental integrity of several of its projects were being questioned. The nascent mechanism should draw a blank slate – the EU argued – and rely on a new standard directly supervised by the UN.

The US went into the talks with a polar opposite vision. It wanted a light-touch approach built on the existing voluntary standards, accepting their requirements and using their infrastructure, according to a leaked EU memo prepared before Cop28 and seen by Climate Home.
The two forces clashed during deeply divisive marathon negotiations in Dubai, failing to find common ground. “Views have become more polarised,” said Pedro Martins Barata, an expert at EDF and a former carbon markets negotiator. “There’s more dissent on an almost philosophical level on what carbon markets should be like.”
After no deal
As the summit drew to a close, the Cop presidency put a ‘take it or leave it’ text on the table. It contained provisions the EU and other groups found unacceptable and was roundly rejected. Negotiators will try again to land a deal at Cop29 next year.
In the meantime, countries can still go ahead with bilateral deals under an initial rulebook agreed two years ago in Glasgow. “Nothing that happened in Dubai prevents countries from moving forward and some will certainly do so,” said Martins Barata.
Switzerland is developing projects with Ghana, Thailand and Vanuatu that will help achieve its climate goals. Singapore inked a similar deal with Papua New Guinea during the summit.

The political stalemate has opened up a big opportunity for players from the voluntary market. They are expected to take a leading role in filling the regulatory gap, experts told Climate Home.
“If a voluntary standard or its projects are given preference by certain countries, it will be a significant stamp of approval and could generate lots of investment,” said Jonathan Crook from Carbon Market Watch.
Voluntary market eyes opportunity
Some are wasting no time. Singapore, a pioneer in bilateral offsets, is partnering up with Verra and Gold Standard, the leading carbon credit registers. Their goal is to create a “playbook” with rules and procedures for countries to use existing carbon credit programs to achieve their climate plans under Article 6.
Hugh Salway, a senior director at Gold Standard, sees an important role for existing operators to speed up the implementation of deals. “A government can create its standard which would take time to develop and would be complicated to maintain,” he told Climate Home. “Or it can use our standard which is already set up with rules, methodologies, and auditors.”
‘Car without wheels’: Adaptation playbook lacks finance target
Another register, the Qatar-based Global Carbon Council (GCC), is also working with a series of credits-producing countries, including Oman and Ghana. They are looking to sell article 6.2 offsets in a first-of-its-kind auction at the beginning of 2024.
“We have been doing this for years, we have the necessary capacity to make it work,” said Kishor Rajhansa, chief operating officer of GCC. Limiting the role of the private sector “would kill off the potential of article 6.2,” he added in an interview at Cop28.
Integrity concerns raised
But some observers are concerned by an outsized influence of existing standards given their chequered record.
Some flagship projects certified by Verra have come under fire for making exaggerated climate claims and for causing alleged environmental and human rights violations. The GCC has been accused of breathing new life into offsets that hardly make any difference to global emissions and would not be accepted anywhere else.
Using voluntary market systems “may simplify things, but it raises many questions about how suitable it is, both for countries and the climate, given all the issues that have been flagged,” said Carbon Market Watch’s Crook.

Chart: Why China’s solar boom is slowing down
Solar power has been a major element of China’s renewables buildout since the mid-2010s.
The country installed 315 gigawatts (GW) of new capacity in 2025, adding more than half of all new solar globally. The year before, it added 277GW.
But the picture in 2026 to date is very different. Installations in March fell 56% year-on-year to 9GW, while new capacity in April totalled 10GW, a 79% drop compared to a year earlier, according to Carbon Brief’s analysis of official data.
Domestic uncertainty
The lower pace in 2026 had been anticipated by analysts.
In previous years, massive solar installations were driven by strong policy support for renewables, including a fixed-price tariff for generators.
In February 2025, the government announced that new solar and wind projects would instead be financed through a new “contract for difference” (CfD)-style system.
Under the new system, power from a certain amount of renewable capacity will be purchased for a fixed “strike price”, which to date has been far lower than previous guaranteed tariffs. Further projects will need to secure their own contracts on the open market.
While the new system is posing challenges for developers in the short term, it is part of a longer-term shift towards market-driven pricing for renewables, which has already made them cheaper than coal.
The change led to a rush of new project installations ahead of the June 2025 cut-off date, so that they could fall under the old fixed-price regime.
New solar additions totalled 45GW in April 2025 and 93GW in May 2025, before falling to 14GW in June 2025, according to Carbon Brief analysis of government data.
Additions also spiked in December, in both 2024 and 2025, as developers raced to meet completion deadlines including those under the 14th five-year plan.
Some reports have attributed the precipitous drop this year to falling demand for solar in China.
But this is a “major oversimplification”, David Fishman, principal at energy consultancy the Lantau Group, wrote on LinkedIn.
The real challenge, he said, is that “developers and banks [are] still figuring out how to finance and build projects without policy-backed revenue guarantees”.
Yang Biqing, energy analyst for Asia at thinktank Ember, agrees, telling Carbon Brief that the new CfD-style system has created “greater uncertainty” for developers, compounded by fierce competition and a growing push for “consolidation” in the industry.
The government set a target for 200GW of new solar and wind capacity in 2026.
Fishman tells Carbon Brief that this will be “difficult” for the government to achieve, though not impossible. Current levels of solar additions – reaching perhaps 120GW for the year – plus an “ambitious” 80GW of new wind power, could help China to hit the target, he says.
Others are more bullish. The China Photovoltaic Industry Association forecasts 180-240GW of new solar in 2026.
But few believe additions will match the breakneck pace of 2025.
“China’s solar industry is no longer a story of capacity expansion”, says Yang, with officials now “increasingly” focused on integrating current generation into the grid.
Soaring exports
Meanwhile, China’s solar exports are still going strong.
China exported almost 1.2m tonnes of solar cells in April 2026, according to Reuters. Although down from a record high in March, it represented a 60% rise year-on-year, added the newswire.
This signals solar’s attractiveness globally in the face of rising energy prices caused by the Iran-US conflict, analysts have said.
High demand for panels has been reported across several continents, including Europe, Asia and Africa.
For example, in the Philippines, the conflict is “driving” solar uptake, one analyst told the Associated Press, adding:
“People want solar and people want solar now.”

A ‘Reforestation Pipeline’ in New Mexico Trains Seedlings to Survive in Burn Scars
Increasing heat and drought are killing young pines planted on ground scorched by wildfires. Can seeds from the toughest trees grown in boot camp nurseries better endure?
Four years after the Calf Canyon/Hermits Peak Fire burned 341,471 acres in northern New Mexico, the massive burn scar from the most destructive blaze in state history still holds vast stretches of leafless, barren and charred trees.
