Around 300 scientists, civil servants, journalists and climate experts took part in the 11th annual Carbon Brief quiz on Wednesday 18 March 2026.
For the second time, this year’s quiz was hosted by Octopus Energy at its headquarters in central London.
In total, 39 teams participated – 25 teams in person and 14 teams joining via Zoom.
Competing teams reflected a wide range of climate change and energy professionals. The list included journalists, civil servants, climate campaigners, policy advisers, energy experts and scientists.
Organisations represented included: Council on Energy, Environment and Water (CEEW) in India; New Scientist; the Times; Business Green; the Bartlett School of Environment, Energy and Resources (BSEER), UCL; Verisk Maplecroft; BBC; World Weather Attribution; Grantham Institute at Imperial; DESNZ; WWF; European Climate Foundation (ECF); the ENDS Report; C40 Cities; Ricardo; Met Office; Meliore; E3G; Danish Meteorological Institute (DMI); Energy Transitions Commission; Carbon Tracker; Ember; Royal Meteorological Society; Civil Service Climate and Environment Network (CSCEN); Changing Markets Foundation; Cerulogy; Oxford Sustainable Law Programme; Université de Lausanne; University of Exeter; Centre for Environment and Sustainability, University of Surrey; UK Parliament; Skeptical Science; ECIU (Energy and Climate Intelligence Unit); Octopus Energy; DeSmog; Department for Transport and Royal School of Mines.
Teams were tested with five rounds of questions – general knowledge, policy, science and two picture rounds. (See the slideshow of the questions and answers below).
After two hours of playing, this year’s winners were announced.
Comprised of players from the Council on Energy, Environment and Water (CEEW) in India, last time’s second place team, “Emissions Impossible” won the coveted Carbon Brief trophy with a total score of 76 out of 100 available points.

In joint second place, with 59 points, were the “Potato-sized nodules”, a mixed team of journalists from New Scientist, the Times and Business Green.
Sharing second place, after leading at the half-way point, were “You cannot BSEERious” from the Bartlett School of Environment, Energy and Resources at UCL.
In fourth place, with 57 points, were “Risky Quizness”, from Verisk Maplecroft.
A certificate was awarded to the BBC for the best team name, as voted for by Carbon Brief staff: “High hopes [low confidence]”.

All the questions and answers from this year’s quiz can be found in this PDF document.
This year’s trickiest round was picture round two, which asked teams to match the quote to the author, with an average score of 5.9 out of 20 available points.
No team correctly guessed that “Chris Funk: Drought, Flood, Fire” was the source of the quote: “How greenhouse gases warm the atmosphere is pretty straightforward. It is really important that we understand this. But almost nobody does, because it is not something that we are taught in school.”
Science was the second hardest round, earning an average score of 6.1 points out of 20.
No team correctly guessed “religious leaders” as the least trustworthy source of climate information, according to a 2025 study using public polling from seven global south countries.
The highest-scoring round was general knowledge, with an average of 13.8 out of 20 questions answered correctly.
Carbon Brief would like to thank all the teams who took part and we look forward to hosting the quiz again in the spring of 2027.

Paris Agreement committee names three countries snubbing it over NDCs
Three countries have been named by the Paris Agreement’s compliance committee for failing to submit a nationally determined contribution (NDC) and repeatedly snubbing offers of help with their climate plans.
After months of internal debate over whether to identify serial non-responders, the Paris Agreement’s Implementation and Compliance Committee (PAICC) named the three countries which have failed to engage with it over their NDCs on Friday.
It named Democratic Republic of Congo, Senegal and North Korea in a footnote of its annual report, adding that it decided to name them “with a view to facilitating engagement”, adding that representatives of the three nations had been invited to its meeting in early 2027 “with the purpose of identifying any challenges and constraints”.
“The Committee noted the importance of Parties engaging with the Committee in a timely manner, while noting that some delays may be due to the national capabilities and circumstances of the Parties”, the report said.
In July, PAICC said 12 countries had ignored its repeated attempts to discuss why they had not published an NDC as required every five years under the 2015 Paris accord.
Members of the committee had been divided over whether to name them, but at a September meeting decided to do so in their annual report to the annual climate COP summit.
By the time the report was published on Friday, only Congo, Senegal and North Korea “had not communicated an NDC or submitted a [Biennial Transparency Report] and had not yet responded to any of the Committee’s notifications, despite several reminders issued by the Committee in this regard”.
Rainforest and renewable energy ambitions
The silence from Congo and Senegal is notable because the former is home to much of the Congo Basin rainforest while the latter has sought billions of dollars in climate finance to support its renewable energy ambitions.
After Brazil, Congo has more rainforest than any country in the world. This forest, and the country’s peatlands, absorb huge amounts of greenhouse gas but are fast being lost to expanding farmland, charcoal production, logging and mining.
Senegal signed a Just Energy Transition Partnership with Canada and wealthy European nations in 2023, to help it meet its renewable energy targets under the-then government of Macky Sall. It was chair of the Least Developed Countries group between January 2022 and December 2023.

Tejas Rao, who is researching the PAICC as part of a doctoral thesis at Cambridge University, said the governments of the three countries should engage with the committee.
“Engagement costs these governments very little and the committee has shown it will listen,” he said.
“Silence leaves the committee with no basis to help, and it leaves the [governments] exposed to the narrative that they are simply disengaged,” he told Climate Home News.
Paris Agreement requirement
The 2015 Paris Agreement requires all parties to publish an NDC every five years outlining their emissions reduction targets, with each plan meant to be more ambitious than the country’s last NDC.
The latest set – the third round of plans, with new targets for 2035 – was due in February 2025. While most countries missed this deadline, all but around 30 – mostly small emitters but including Egypt, Vietnam and Argentina – have now submitted them.
Over the year, the PAICC – which is made up of government climate officials from developed and developing countries – has been communicating with governments that have not submitted NDCs and trying to overcome barriers to them doing so.
Some nations have cited exceptional circumstances as the reason for not submitting an NDC, a process that requires a significant amount of work in tracking emissions and consulting on how to curb them across the economy. For example, a letter from a Sudanese official to the PAICC, seen by Climate Home News, said that the country’s civil war had led to the suspension of its NDC preparation.
The US and Iran are not signed up to the Paris Agreement and so do not have active NDCs, nor does Taiwan, which is not a UN member state.
Rao said that because the PAICC is “facilitative and non-punitive”, naming the countries “is meant to open a door, not close one – the invited consultation is the point”.
“In recent months, governments that explained their constraints, whether capacity, finance or domestic process, have been met with follow-up and support rather than sanction, and the number of silent governments has fallen sharply,” Rao said.
