Burning all the oil and gas from new discoveries and newly approved projects since 2021 would emit at least 14.1bn tonnes of carbon dioxide (GtCO2), according to Carbon Brief analysis of Global Energy Monitor (GEM) data.
This would be equivalent to more than an entire year’s worth of China’s emissions.
It includes 8GtCO2 from new oil and gas reserves discovered in 2022-23 and another 6GtCO2 from projects that were approved for development over the same period.
These have all gone ahead since the International Energy Agency (IEA) concluded, in 2021, that “no new oil and gas fields” would be required if the world were to limit global warming to 1.5C .
Since then, world leaders gathering at the COP28 summit at the end of 2023 have also agreed to “transition away from fossil fuels”.
Despite this, nations such as Guyana and Namibia are emerging as entirely new hotspots for oil and gas development. At the same time, major historic fossil-fuel producers, such as the US and Iran, are still going ahead with large new projects.
Additionally, oil majors such as TotalEnergies and Shell that have made public commitments to climate action, are among the biggest players investing in new oil and gas extraction around the world.
More oil, more CO2
In 2021, the IEA issued its first “net-zero roadmap”, setting out a pathway for the world to limit warming to 1.5C. The influential agency concluded that:
“Beyond projects already committed as of 2021, there are no new oil-and-gas fields approved for development in our pathway.”
This statement has become a rallying cry for campaigners and leaders pushing for a phase out of fossil fuels.
The IEA has since clarified that there would be no need for new oil and gas developments if the world gets on track for 1.5C. It has also slightly softened its language, by allowing for new oil and gas projects with a “short-lead time” within its 1.5C scenario.
Yet it has also warned of the risk of “overinvestment” in new developments, noting that current spending is “almost double” what would be needed under its 1.5C pathway.
In any case, the IEA’s message has been widely ignored by oil and gas companies, which have continued to search for new extraction opportunities.
In its new global oil and gas extraction tracker, GEM identifies 50 new sites discovered in 2022 and 2023, after the IEA issued its initial net-zero roadmap. The oil and gas reserves from these projects amount to 20.3m barrels of oil equivalent (Mboe).
The tracker also identified a further 45 projects that have reached “final investment decision” (FID) since the IEA’s roadmap, with an extra 16Mboe of reserves. FID is the point at which companies decide to move ahead with a project’s construction and development.
If all the oil and gas in the newly discovered reserves is burned in the coming years, an extra 8GtCO2 would be released into the atmosphere, according to Carbon Brief analysis. Adding the reserves discovered between 2022-23 brings this total to 14.1GtCO2.
This is equivalent to more than one-third of the CO2 emissions from global energy use in 2022, or all the emissions from burning oil that year, as shown in the chart below.

These findings are in line with mounting evidence that both company and government plans for fossil fuels are not aligned with their own climate goals.
According to the most recent UN Environment Programme “production gap” report, companies are planning for oil and gas production that is 82% and 29% higher, respectively, than would be needed in a 1.5C pathway.
The remaining “carbon budget” of emissions that can be released while retaining a 50% chance of limiting warming to 1.5C is just 275GtCO2, according to the Global Carbon Budget consortium of scientists. Burning all of the contents of the new oil and gas schemes identified by GEM would use up 5% of this remaining budget.
Moreover, the GEM report points out that new projects take, on average, 11 years to start producing significant amounts of oil and gas. This means that most will not enter production until the 2030s.
By this point, according to the IEA, fossil-fuel demand would have fallen by “more than 25%” if the world gets on to a 1.5C-compliant pathway.
GEM also notes that its analysis likely underestimates the scale of new fossil fuel developments. It excludes smaller sites and those where the size has not been publicly announced, such as new gas fields discovered in Saudi Arabia in 2022.
The IEA updated its net-zero scenario in 2023 to reflect the continued expansion of fossil-fuel projects since its previous report. It stated that:
“No new long lead time conventional oil and gas projects need to be approved for development.”
It added that falling demand for fossil fuels “may also mean that a number of high cost projects come to an end before they reach the end of their technical lifetimes”, again if the world gets onto a 1.5C pathway.
To reflect the IEA’s new language around avoiding “long lead time” and “conventional” projects, GEM excludes expansions of existing projects and “unconventional” sites from its analysis. The report notes that including them would roughly quadruple the size of the reserves that reached a FID in 2022-23.
Oil majors
Many oil companies have made it clear that they do not intend to wind down their fossil-fuel operations in the near future.
This is true even for those that have made commitments to climate action, such as Shell and TotalEnergies. (Some oil majors have also watered down their pledges in recent months.)
As the chart below shows, many of the companies with the largest share of new oil and gas schemes have also announced net-zero targets.

The top rankings are dominated by publicly traded oil majors, such as ExxonMobil, and national companies, such as the Abu Dhabi National Oil Company (ADNOC) – which is led by COP28 president Sultan Al Jaber. Saudi Aramco, the world’s largest oil company, is missing from the GEM tracker, likely due to the lack of data from Saudi Arabia.
The emissions that could result from new gas fields run by the state-owned National Iranian Oil Company alone amount to 1,700MtCO2, according to Carbon Brief analysis. This is higher than the annual carbon footprint of Brazil.
Meanwhile, oil and gas in new projects being developed by TotalEnergies and ExxonMobil could generate roughly 1,000MtCO2 – equivalent to Japan’s annual total – for each company.
At the recent CERAWeek industry conference, many oil and gas industry leaders argued against a transition to cleaner forms of energy. For example, Saudi Aramco chief executive Amin Nasser told attendees: “We should abandon the fantasy of phasing out oil and gas.”
As companies continue searching for more oil and gas, executives have consistently emphasised that demand for fossil fuels, rather than production, is the problem.
Most recently, in an interview with Fortune, ExxonMobil chief executive Darren Woods placed the blame on the public, who he said “aren’t willing to spend the money” on low-carbon alternatives.
New country ‘hotspots’
New nations, mainly in the global south, are opening up as “global hotspots” for oil and gas projects, according to GEM.
Notably, Guyana is set to have the highest oil production growth through to 2035. Over the past two years, it has already been the site of more new oil and gas discoveries than any other country. Namibia has also opened up as a major new frontier in fossil-fuel extraction.
The chart below shows how nations that have recently been targeted for oil and gas exploration, now make up a large portion of new discoveries and developments.

The expansion of oil and gas production in the global south is a highly politicised topic.
Many African leaders, in particular, argue that their countries are entitled to exploit their natural resources in order to bring benefits to their people, as global-north countries have done. At COP28, African Group chair Collins Nzovu stated that oil and gas were “crucial for Africa’s development”.
(It is worth noting that, according to GEM’s analysis, companies based in the global north such as ExxonMobil, Hess Corporation and TotalEnergies own most of the reserves in the new global-south projects.)
Meanwhile, wealthy oil producers such as the US, Norway and the UAE justify their continued fossil-fuel extraction by saying their production emissions are relatively low. Others, such as the UK, argue that they need to exploit domestic reserves to preserve their energy security.
Even in a 1.5C scenario, the IEA still includes a significantly reduced amount of oil and gas use in 2050. Most of it goes towards making petrochemicals and producing hydrogen fuel.
However, in last year’s report on the position of the oil and gas industry in the net-zero transition, the agency also emphasises that this does not mean everyone can continue producing.
“Many producers say they will be the ones to keep producing throughout transitions and
beyond. They cannot all be right,” it concludes.

Science ‘under attack’ from fossil fuel interests at UN climate talks
Dozens of countries have called out growing “coordinated attacks” by fossil fuel interests aimed at undermining the role of climate science in the UN negotiations at the mid-year talks in Bonn.
Under the banner of ‘Friends of Science’, in an overflowing press conference room lined with negotiators and civil society supporters, diplomats from Fiji, Nepal, the European Union, Switzerland, Sierra Leone and Panama vowed to ensure that decision-making in the UN climate process remains based on the “best available science”. That includes reports from the Intergovernmental Panel on Climate Change (IPCC), the UN’s climate science body, they said.
While steering clear of singling out any specific country, they said efforts to cast doubt on established scientific concepts, such as the 1.5 global warming limit, are led by “the usual suspects” and those who think “science threatens their economic prospects”.
Saudi Arabia and India have opposed calls in draft texts to encourage scientific work on scenarios that would minimise the magnitude and duration of any overshoot of 1.5C, according to one negotiator in the room and summaries of closed-door discussions published by a reporting service.
UN chief António Guterres conceded last year that a temporary breach of the key warming limit is inevitable, while urging countries to redouble efforts to bring temperatures back down.
‘Polluted narrative’
Scientists have long established that burning fossil fuels is the primary cause of man-made climate change and a rapid shift away from oil, coal and gas is essential to curb global warming.
Saudi Arabia is dependent on oil and gas exports, while India largely relies on coal to power its economic development.
One negotiator said that research on how climate action can be equitable for developing countries, produced by Indian universities, had been published too late to be incorporated into the last IPCC assessment report in 2023. This incident led the Indian government to try and discredit the IPCC, they said. Some Indian scientists have argued that the IPCC’s scenarios are unfair on developing countries.
Saudi Arabia and India have played down the importance of making sure that the latest IPCC assessments – regarded as the gold standard of climate science – are available for the next global stocktake, the UN scorecard of climate action around the world.
“Anyone that is blocking references to science – they are not our friends,” Sivendra Michael, lead negotiator for Fiji, told a press conference, highlighting the rise of a “polluted narrative” both inside and outside the negotiating rooms.
1.5C is a ‘hard limit’
Speaking for the AILAC coalition of Latin American countries, Panama’s Ana Aguilar said they went to Bonn to negotiate positions, not to negotiate the facts laid out by science.
“We see coordinated efforts to cast doubt on the best available science driven by a narrow set of interests, not by the needs of our people,” she added. “We have seen this playbook before… manufacture doubt, delay the response and let the vulnerable people pay this bill.”


The ‘Friends of Science’ coalition stressed that the 1.5C goal of the Paris Agreement cannot be negotiated, as the survival of the most climate vulnerable communities is at stake if it is permanently breached.
“Science tells us that 1.5C is a hard limit for many countries, including the small island developing states and least developed countries,” said Manjeet Dhakal, a negotiator for Nepal. “We still have a chance to keep 1.5 degrees in reach and minimise the overshoot if we act fast and drastically.”
Long-running IPCC standoff
While diplomats claimed attacks on science are broadening, one long-standing issue of contention is whether the latest assessment reports of the IPCC will be ready in time for the next UN global stocktake due to start this November and end in 2028.
This matters because, as some experts have pointed out, previous IPCC findings played a key role in the first such exercise, which culminated at COP28 in Dubai in the landmark agreement on transitioning away from fossil fuels in energy systems.
Since the start of the latest IPCC assessment cycle, known as AR7, a battle over the timing has dragged on for over two years at successive IPCC meetings, with governments repeatedly failing to find a breakthrough.
A large majority of nations have been pushing for an accelerated timeline that would ensure the AR7 reports can be fed into the UN’s global stocktake. But a group of countries, including Saudi Arabia, India, China, Russia and Kenya, have said at previous IPCC meetings they want a longer process, arguing a fast-tracked assessment would put a burden on developing countries with limited resources.
Science and the stocktake
That fight has now bled into the Bonn talks where governments began discussing the arrangements for the next stocktake. At a session earlier this week, most developed countries, Latin American and small island states, and the world’s poorest nations emphasised the assessment of collective climate action must be guided by the “best available science” – code for the findings of the IPCC reports.
The Maldives, speaking for small island states, said IPCC science remains “essential to the integrity, credibility and usefulness” of the stocktake. AILAC said that starting the process “on the right footing” requires a political decision on the timeline to deliver the AR7 reports in time. Switzerland said IPCC reports “ask more than is politically comfortable, but that is precisely why they must guide every decision we make”.
Saudi Arabia, however, said no particular scientific input – and in particular what comes out of the IPCC – should be prioritised. Similarly, India warned against creating “some kind of preferred hierarchy” in the role that any specific source of information should play in the process.
Ghana’s Antwi-Boasiako Amoah, who chairs the African Group, told a press conference on Tuesday that some countries think rushing to get IPCC inputs into the global stocktake could “undermine or compromise the IPCC process”. “Africa is for science,” he said, without saying where the continent stands on the IPCC timeline.
Crunch talks in October
At the “Friends of Science” press conference, Dhakal pushed back on the idea that science would have to be rushed to be incorporated. He said the IPCC leadership has “perfectly made it clear” that they can deliver the report before the global stocktake. “It is the scientists who are saying they can deliver it on time,” he said.


The discussion will be picked up again at the next IPCC session in October, where its boss Jim Skea is hoping to reach an agreement. “As a scientist myself, I cannot overstate the importance of this decision,” he told governments in Bonn last week.
Andreas Sieber, head of political strategy at campaigning group 350.org, told Climate Home News that the debate may sound procedural, “but it is anything but”. “Science is the backbone of the Paris Agreement ambition cycle, and the evidence assessed through AR7 will help determine not only the emissions pathways countries pursue, but also how the world responds to mounting climate losses and who receives support,” he said in Bonn.

Key developments
Ocean talks
MAKING WAVES: African and Commonwealth countries issued a “call to action” to implement the High Seas Treaty at the Our Ocean Conference in Kenya this week, reported the Associated Press. The summit, which ends on 18 June, is focused on ocean issues including “climate change, biodiversity and pollution”, said the newswire. The UK government announced £13.9m in marine-related funding at the summit.
OCEAN ‘STRAIN’: Climate change, pollution, overfishing and biodiversity loss are putting oceans under “severe strain”, according to a UN report. The third “world ocean assessment” noted that conservation efforts have also “grown”, including through “nature-based solutions, ecosystem restoration and sustainable management techniques”. Meanwhile, another UN report said that fisheries and aquaculture production reached an all-time high of 235m tonnes in 2024.
OBSERVATION ISSUES: Scientists told the Guardian that the Trump administration’s plan to dismantle a key ocean-observation system run by the US would “severely degrade” the accuracy of weather forecasts around the world. Several Democratic and one Republican lawmaker pushed back against the plan to get rid of the system, reported the Associated Press. [For more, see the first edition of Cited, Carbon Brief’s newsletter on climate science.]
Plant and fungi update
OFF-KILTER: Plant flowering times have “shifted significantly” over the last century, according to an AI-assisted analysis of 8m “digitised herbarium specimens” in the latest “state of the world plants and fungi” report from the Royal Botanic Gardens Kew. The report stated there have been “both advances and delays” in flowering date, with a median shift of 2.5 days per decade in either direction. The greatest variation was observed in the tropics, it added.
‘NEW ERA’: The report highlighted that Kew recently completed a digitisation of 7.4m herbarium and fungarium specimens in its collection. The ongoing digitisation of specimens around the world, alongside AI technology, could “transform understanding of biodiversity loss and climate change and pave the way to resolving these seemingly intractable crises”, it said.
EXTINCTION RISK: In its coverage of the report, the Guardian said that AI and digitalisation could help scientists document “vital” plant species “before they vanish”. About 40% of the world’s “assessed” 70,000 plant species are at risk of extinction, while a further 330,000 are yet to be analysed, according to the newspaper. The situation for fungi is “even more stark”, it reported, with 90% of an estimated 2m species still “unknown to science” and less than 1% of known species assessed for extinction risk.
News and views
- BEEF TRACKS: A “landmark” law in Colombia requiring the beef industry to prove supply chains are deforestation-free has taken effect, reported the Associated Press. The measure is part of efforts to “reverse decades of forest loss, much of it driven by the expansion of cattle ranching into previously forested areas”, noted the newswire.
- CONTINGENCY PLAN: With El Niño conditions officially confirmed as underway, the Indian government called for an “overhaul” of agricultural districts’ plans for managing the impact of below-normal rainfall on crops, reported Down to Earth. Around 150-200 districts have been identified as “most critical” based on projections, the outlet noted.
- MEATIER: Global meat supply has increased fourfold in the past six decades, according to a UN report covered by the Guardian. Agriculture’s “planet-heating emissions are forecast to rise by 7.6% over the next decade” as food production continues to grow, the newspaper said.
- TREES, NOT TARMAC: Kenya’s former chief justice, David Maraga, was among a number of protesters arrested in Nairobi for demonstrating against plans to turn 75 acres of Nairobi National Park into a car park, reported Kenya’s Daily Nation. Demonstrators were en route to deliver a petition to Kenya’s Wildlife Service when they were interrupted by anti-riot police officers, according to the newspaper.
- MANGROVES BACK, ALRIGHT: A new study covered by BBC News found that mangrove forests are “staging an unexpected comeback” globally. The broadcaster said mangroves had been “declining rapidly as they were cleared for fish farms and housing”, but the world is now “gaining more mangroves than it has been losing”.
- ‘LIMITED’ PROGRESS: Some 59% of the world’s largest financial institutions do not have a deforestation policy in place, according to the latest “forest 500” report from Global Canopy. The report – which assesses the 150 financial institutions that provide the most financing to the 500 companies with the “greatest influence” on deforestation – described finance sector progress on forest loss in 2025 as “limited”.
Spotlight
Coral reef ‘hope’
This week, Carbon Brief reports on research estimating coral reef resilience.
New research offers a sliver of “hope” that 30% of the world’s coral reefs could be “resilient” against the harmful effects of climate change.
The study, which is in the final stages of peer review and due to be published soon, identified swathes of reefs that have the best potential to withstand and recover from marine heatwaves and other stressors.
Climate change is a major threat to the survival of coral reefs. In a 2018 report, the UN’s science body warned that reefs could decline by an additional 70-90% at 1.5C of warming and as much as 99% under 2C.
The areas of potentially resilient reefs identified in the new study span almost 166,000 square kilometres – an area twice the size of Scotland.
These reefs are spread across 71 countries and 100 territories, but 61% are found in the territorial waters of just five nations – Australia, the Bahamas, Cuba, Indonesia and the Philippines.
The lead study author, Dr Kyle Zawada from Macquarie University in Australia, told Carbon Brief that the research shows the areas that could most likely “persist through climate change”. He added:
“[Coal reefs] are obviously in dire straits – but that’s not to say there are not pockets of resistance and pockets of resilience.”
Fewer than 30% of the reefs deemed to be the most climate-resilient are contained in protected or conserved areas, the study noted.
The map below shows a snapshot of the findings, highlighting the Great Barrier Reef off the north-eastern coast of Australia. The light pink areas are regular reefs, while the slightly darker pink are “climate-resilient” reefs.

Reef maps
The team, led by researchers from Macquarie University and the Wildlife Conservation Society, used the findings from more than 45,000 research surveys on corals over 1960-2025 in modelling simulations to create a map of coral cover around the world in 2020 and projections for 2050.
The modelling looked at various scenarios of future emissions and the researchers developed criteria to determine which reefs could be best positioned to survive or recover from extreme events and higher temperatures.
This specified that, for example, larger-sized reefs and those with a wide diversity of coral species tend to be more resilient than smaller areas with a lower variety of coral.
Zawada told Carbon Brief that the study does not replace real-life observations of how reefs respond to extremes. But, he added, it offers a “good guess” of areas to protect:
“It would be nice to say that there are these little reefs of hope, obviously with the massive asterisks that this doesn’t mean that these ones are out of the woods…and to sort of use that as a rallying call for us to take that hope forward and have a look at these reefs.”
