Record numbers of delegates have been registered for this year’s COP28 climate summit in the United Arab Emirates (UAE), making it potentially the largest in COP history by some distance.
More than 80,000 participants have badges for this year’s Conference of the Parties (COP) in Dubai.
This is 30,000 more than travelled to Sharm El-Sheikh in Egypt for COP27 last year, the previous largest in an almost 30-year history of summits.
For the first time in COP history, every single delegate has been named in the participant lists.
Previous COPs have typically seen thousands of “overflow” participants in which countries and UN agencies could nominate delegates without their names appearing on their official lists.
Also named this year are “host country guests” – those receiving badges as guests of the UAE.
Recipients include former UK prime ministers Boris Johnson and Tony Blair, Microsoft co-founder Bill Gates, CEO and chairman of French energy giant EDF Luc Rémont and NATO secretary general Jens Stoltenberg.
This year, 3,000 “virtual” participants are also named, which takes the overall provisional delegate total for COP28 to around 84,000.
Unsurprisingly, the UAE has the largest-ever registered delegation of any country, with 4,409 badges. This is followed by Brazil with 3,081 and then China and Nigeria, who both have issued 1,411 badges.
Record numbers
For the first time in COP history, the participant lists have been published by the United Nations Framework Convention on Climate Change (UNFCCC) in spreadsheet format, rather than as pdf documents.
The provisional total for COP28 suggests that 81,027 delegates have registered to attend the summit in person. With a further 3,074 attending virtually, this takes the overall total to 84,101.
As the chart below shows, this comfortably makes the Dubai event the largest COP in history. For comparison, the first climate COP – held in Berlin in 1995 – had 3,969 delegates.
Last year’s COP in Sharm El-Sheikh received almost 50,000 delegates, which put it some distance ahead of the 38,000 that attended COP26 in Glasgow in 2021. It highlights a trend of increasing participation at climate COPs following a dip in attendance after the peak of COP21 in Paris in 2015.
It should be noted that these are provisional figures, based on the delegates that have registered for the summit. The UNFCCC will release the final figures – based on participants collecting a physical badge at the venue – after the summit has closed.

Overall totals for delegates from parties, observers and the media for all COPs, as published by the UNFCCC (see this article for more details on the data). Data for COPs 1-27 are the “final” figures, while COP28 data is “provisional”. Chart by Carbon Brief.
As usual, the lists are divided between the different types of groups and organisations attending the summit. The largest group at COP28 is for delegates representing parties. These are nation states, plus the European Union, that have ratified the convention and play a full part in negotiations. This group adds up to 24,488 delegates – more than double the number at COP27 last year.
Unusually, the participant lists for this year also name the “overflow” badges that have been given out. For the UK delegation, examples include 21 members of Prime Minister Rishi Sunak’s press delegation, 16 members of King Charles’s royal household and 18 members of parliament.
For consistency with Carbon Brief’s analysis of previous COPs, the above chart includes this group separately, but the participant lists this year do divide the overflow delegates between groups. Including the overflow numbers takes the total for party representatives to 51,695 – by itself, more than the total number of delegates at any previous COP.
As at COP27, there are no longer any “observer” states now that the Holy See – the government of the Roman Catholic Church, which operates from Vatican City State and is led by the pope as the bishop of Rome – has become a full party to the Convention.
The next-largest group is that of observers from non-governmental organisations (NGOs), which totals 14,338 delegates – again, comfortably the largest for this group in COP history.
Along with the NGOs, there are several other groups that fall into the category of “observer organisations” – such as those participants representing UN bodies, intergovernmental organisations, other agencies and business representatives. These total 3,623 registered delegates – or 4,754 when overflow badges are included.
Finally, another record-breaking group is the number of media delegates – clocking in at 3,972. This total potentially tops the 3,712 media representatives at COP3 in Kyoto in 1997.
UAE largest delegation
The UAE has registered the largest delegation of any party, totalling 4,409 participants – including overflow badges. Even without overflow badges – which hugely swell delegation size – UAE’s group of 620 would be its largest in COP history.
The UAE’s registered delegation at COP27 last year was potentially larger at 1,073 people, but just 436 attended, according to the final lists, putting it second-largest behind Brazil’s delegation of 467.
Brazil has again registered a large delegation for this year’s COP – 3,081 participants including overflow badges – meaning it is only behind UAE for overall delegation size.
Other delegations surpassing 1,000 include China and Nigeria who have both registered 1,411 people, followed by Indonesia with 1,229, Japan 1,067 and Turkey with 1,045.
(It is worth noting that some countries allocate some of their party badges to NGOs, which can artificially inflate the size of their official delegation.)
At the other end of the scale, the smallest delegations have been registered by North Korea (two), Nicaragua (six), Eritrea (seven) and Liechtenstein and Moldova (both eight).
For the third year in a row, both Afghanistan and Myanmar have not registered a delegation to the COP, while San Marino is also not present on the provisional lists this year.
The map and chart below present the delegation size – split between party and overflow badges – for all the countries registered for COP27. The darker the shading, the more delegates that country has signed up. Mouse over the countries to see the number of delegates and the population size.
Gender balance
Along with the names in the participant lists, the UNFCCC also typically provides a title – such as Mr, Ms, Sr or Sra – for each registered participant. In the past, this has allowed Carbon Brief to work out the balance of men to women in the delegations that each country has sent to a COP.
(This analysis always carries the caveat that the titles are designated by UNFCCC and not by Carbon Brief. In addition, Carbon Brief recognises that gender is not best categorised using a binary “male” or “female” label and appreciates that the UNFCCC’s lists may not be wholly accurate.)
However, this year’s lists are slightly different. First, there are a number of participants – particularly, for no obvious reason, in the Canadian delegation – that have not been given a title at all. And other titles that do not indicate gender – such as Dr, Prof, Ambassador and Honourable – have also been used frequently.
Therefore, for this COP28 analysis, these non-gendered titles – which make up around 330 names of more than 24,000 in the list of party delegates – have been excluded.
This gives an average gender balance of party delegations of 62% male to 38% female. The chart below shows how this compares with previous COPs – note that, for consistency, the COP28 figure only includes those on party badges, not overflow ones.
There is just one all-male party delegation this year, which is the two-strong group representing North Korea.

The average size of named party delegations (not including overflows) for each COP, divided by male (orange) and female (purple) participants. The lines show what percentage of the average delegation is male (orange) and female (purple). Data for COPs 1-27 collated from “final” participant lists published by the UNFCCC, while COP28 data is based on the “provisional” list. Note that around 330 delegates in the COP28 provisional list are not included because there is no information on their gender. Chart by Carbon Brief.

The Global Energy Supply in a Decade ‘Is Not a World We’re Going to Recognize’
With the U.S. bombing Iran and the Strait of Hormuz closed, energy experts say countries transitioning to renewables will be more resilient in the “face of the shock.”
The United States’ war on Iran could fundamentally alter how countries consume and generate energy and hamper international progress in combating climate change, a panel of energy experts said today.

Iran war analysis: How 60 nations have responded to the global energy crisis
One month into the US and Israel’s war on Iran, at least 60 countries have taken emergency measures in response to the subsequent global energy crisis, according to analysis by Carbon Brief.
So far, these countries have announced nearly 200 policies to save fuel, support consumers and boost domestic energy supplies.
Carbon Brief has drawn on tracking by the International Energy Agency (IEA) and other sources to assess the global policy response, just as a temporary ceasefire is declared.
Since the start of the war in late February, both sides have bombed vital energy infrastructure across the region as Iran has blocked the Strait of Hormuz – a key waterway through which around a fifth of global oil and liquified natural gas (LNG) trade passes.
This has made it impossible to export the usual volumes of fossil fuels from the region and, as a result, sent prices soaring.
Around 30 nations, from Norway to Zambia, have cut fuel taxes to help people struggling with rising costs, making this by far the most common domestic policy response to the crisis.
Some countries have stressed the need to boost domestic renewable-energy construction, while others – including Japan, Italy and South Korea – have opted to lean more on coal, at least in the short term.
The most wide-ranging responses have been in Asia, where countries that rely heavily on fossil fuels from the Middle East have implemented driving bans, fuel rationing and school closures in order to reduce demand.
‘Largest disruption’
On 28 February, the US and Israel launched a surprise attack on Iran, triggering conflict across the Middle East and sending shockwaves around the world.
There have been numerous assaults on energy infrastructure, including an Iranian attack on the world’s largest LNG facility in Qatar and an Israeli bombing of Iran’s gas sites.
Iran’s blockade of the Strait of Hormuz, a chokepoint in the Persian Gulf, is causing what the IEA has called the “largest supply disruption in the history of the global oil market”.
A fifth of the world’s oil and LNG is normally shipped through this region, with 90% of those supplies going to destinations in Asia. Without these supplies, fuel prices have surged.
Governments around the world have taken emergency actions in response to this new energy crisis, shielding their citizens from price spikes, conserving energy where possible and considering longer-term energy policies.
Even with a two-week ceasefire announced, the energy crisis is expected to continue, given the extensive damage to infrastructure and continuing uncertainties.
Asian crunch
Carbon Brief has used tracking by the IEA, news reports, government announcements and internal monitoring by the thinktank E3G to assess the range of national responses to the energy crisis roughly one month into the Iran war.
In total, Carbon Brief has identified 185 relevant policies, announcements and campaigns from 60 national governments.
As the map below shows, these measures are concentrated in east and south Asia. These regions are facing the most extreme disruption, largely due to their reliance on oil and gas supplies from the Middle East.

Nations including Indonesia, Japan, South Korea and India are already spending billions of dollars on fuel subsidies to protect people from rising costs.
At least 16 Asian countries are also taking drastic measures to reduce fuel consumption. For example, the Philippines has declared a “state of national emergency”, which includes limiting air conditioning in public buildings and subsidising public transport.
Other examples from the region include the government in Bangladesh asking the public and businesses to avoid unnecessary lighting, Pakistan reducing the speed limit on highways and Laos encouraging people to work from home.
Europe – which was hit hard by the 2022 energy crisis due to its reliance on Russian gas – is less immediately exposed to the current crisis than Asia. However, many nations are still heavily reliant on gas, including supplies from Qatar.
The continent is already feeling the effects of higher global energy prices as countries compete for more limited resources.
At least 18 European nations have introduced measures to help people with rising costs. Spain, which is relatively insulated from the crisis due to the high share of renewables in its electricity supply, nevertheless announced a €5bn aid package, with at least six measures to support consumers.
Many African countries, while also less reliant on direct fossil-fuel supplies via the Strait of Hormuz than Asia, are still facing the strain of higher import bills. Some, including Ethiopia, Kenya and Zambia, are also facing severe fuel shortages.
There have been fewer new policies across the Americas, which have been comparatively insulated from the energy crisis so far. One outlier is Chile, which is among the region’s biggest fuel importers and is, therefore, more exposed to global price increases.
Tax cuts
The most common types of policy response to the energy crisis so far have been efforts to protect people and businesses from the surge in fuel prices.
At least 28 nations, including Italy, Brazil and Australia, have introduced a total of 31 measures to cut taxes – and, therefore, prices – on fuel.
Even across Africa, where state revenues are already stretched, some nations – including Namibia and South Africa – are cutting fuel levies in a bid to stabilise prices.
Another 17 countries, including Mexico and Poland, have directly capped the price of fuel. Others, such as France and the UK, have opted for more targeted fuel subsidies, designed to support specific vulnerable groups and industries.
These measures are all shown in the dark blue “consumer support” bars in the chart below.

Such measures can directly help consumers, but some leaders, NGOs and financial experts have noted that there is also the risk of them driving inflation and reinforcing reliance on the existing fossil fuel-based system.
Christine Lagarde, president of the European Central Bank, spoke in favour of short-term measures to “smooth the shock”, but noted that “broad-based and open-ended measures may add excessively to demand”.
Measures to conserve energy, of the type that many developing countries in Asia have implemented extensively, have been described by the IEA as “more effective and fiscally sustainable than broad-based subsidies”.
So far, there have been at least 23 such measures introduced to limit the use of transport, particularly private cars.
These include Lithuania cutting train fares, two Australian states making public transport free and Myanmar and South Korea asking people to only drive their cars on certain days.
Clean vs coal
At least eight countries have announced plans to either increase their use of coal or review existing plans to transition away from coal, according to Carbon Brief’s analysis. These include Japan, South Korea, Bangladesh, the Philippines, Thailand, Pakistan, Germany and Italy.
These measures broadly involve delaying coal-plant closure, as in Italy, or allowing older sites to operate at higher rates, as in Japan – rather than building more coal plants.
There has been extensive coverage of how the energy crisis is “driving Asia back to coal”. However, as Bloomberg columnist David Fickling has noted, this shift is relatively small and likely to be offset by a move to cheap solar power in the longer term.
Indeed, some countries have begun to consider changes to the way they use energy going forward, amid a crisis driven by the spiralling costs of fossil-fuel imports.
Leaders in India, Barbados and the UK have explicitly stressed the importance of a structural shift to using clean power. Governments in France and the Philippines are among those linking new renewable-energy announcements with the unfolding crisis.
New renewable-energy capacity will take time to come online, albeit substantially less time than developing new fossil-fuel generation. In the meantime, some nations are also taking short-term measures to make their road transport less reliant on fossil fuels.
For example, the Chilean government has enabled taxi drivers to access preferential credit for purchasing electric vehicles (EVs). Cambodia has cut import taxes on EVs and Laos has lowered excise taxes on them.
Finally, there have been some signs that countries are reconsidering their future exposure to imported fossil fuels, given the current economics of oil and gas.
The New Zealand government has indicated that a plan to build a new LNG terminal by 2027 now faces uncertainty. Reuters reported that Vietnamese conglomerate Vingroup has told the government it wanted to abandon a plan to build a new LNG-fired power plant in Vietnam, in favour of renewables.

US Senators Investigate $370 Million IRS Payout to Cheniere Energy
Seven Senate Democrats launched the probe over controversial tax credits to the country’s largest exporter of liquefied natural gas.
Seven Democratic U.S. senators have launched a probe into a $370 million “alternative fuel” payout to Cheniere Energy, made earlier this year by the IRS, that critics say the liquefied natural gas export company never should have received.
