More than 450 scientists, civil servants, journalists and climate experts took part in the ninth annual Carbon Brief quiz on Wednesday 8 November 2023.

Carbon Brief hosted more than 200 guests in London, with hundreds more playing online.

This is the second year in a row the quiz has been hosted in London. In 2021, the event was held in Glasgow during COP26, while in 2020, the quiz was held entirely online due to Covid-19 restrictions.

In total, 53 teams participated this year – 22 teams in person and 31 teams joining via Zoom.

Teams competing 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: UK Parliament; Met Office; Committee on Climate Change; WWF-UK; UCL; E3G; Imperial College’s Grantham Institute; University of East Anglia; HM Treasury; Wellcome Trust; BusinessGreen; Department for Transport; Danish Meteorological Institute; Ember; Climate Analytics; Bloomberg; DeSmog; University of Surrey; Oxford University’s Smith School of Enterprise and the Environment; and the Sunrise Project.

Before the quiz, Carbon Brief’s editor and director Leo Hickman paid tribute to friends of Carbon Brief, veteran climate negotiator Prof Pete Betts CBE, climate scientist Prof Saleemul Huq OBE and former Guardian environment editor John Vidal, who sadly passed away this year.

Teams were tested with five rounds of questions – general knowledge, policy, science and two picture rounds. (See a slideshow of the questions and answers below).

After two hours of competitive quizzing, this year’s winners were announced. “The Climate Justice League”, which was made up of policy experts and journalists from the Centre for Science and Environment (CSE) and Down to Earth in India, won the coveted Carbon Brief trophy for the second year running, dropping only four points out of a total 100 available. The team accepted the trophy over Zoom at 2am local time in New Delhi. 

The 2020 and 2021 champions, the University of East Anglia (UEA), placed second, with 64 points.

Tied in third place with 60 out of a total 100 available points were “Call me Mabey” from E3G and “Who You Gonna Call? Coalbusters?” from Ember.

All the questions and answers can be found in this PDF document. (Carbon Brief also tweeted throughout the event using the #CBQuiz hashtag.)

In an always-tricky quiz, one of the least correctly answered questions in the general knowledge round was: where in England was the 2023 hit movie Barbie mostly filmed? Just four teams gave the correct answer of “Leavesden”. And in the science round, just 10 teams knew – or guessed correctly – that the occupation of George Hadley, the amateur meteorologist after whom the Hadley Cell is named, was “lawyer”.

Carbon Brief would like to thank all the teams who took part and we look forward to hosting the quiz again in the autumn of 2024. If you would like to participate in next year’s quiz, please contact us in advance.

Governments defend energy transition as US snubs renewables agency

Published

on

After the United States announced last week it would withdraw from the International Renewable Energy Agency (IRENA), effectively slashing more than a fifth of its core budget, the organisation’s head said it could “manage” the US exit, as top officials argued the energy transition is “unstoppable”.

Speaking to reporters at IRENA’s 16th Assembly in Abu Dhabi, Director-General Francesco La Camera said the US had yet to formally notify the agency it would be leaving. IRENA’s statute says withdrawal of a member country takes effect at the end of the year in which it is notified.

Until that point, they remain a member with all its rights, including the right to vote, but also “the duty to pay”, La Camera added.

    On Sunday, IRENA’s member countries – around 170 in total – adopted a budget for the coming two years, which shows the US is expected to contribute 22% of IRENA’s core funding, with its share amounting to nearly $5.7 million for 2026.

    La Camera said IRENA is already talking to governments and the private sector to fill the potential financial hole if the US does not deliver on its financial obligations, as has been the case in previous years with the UN climate secretariat and the Green Climate Fund.

    “We know that some of these usual donors are considering to put something in our budget – we are also trying to get some money from the companies that are part of our initiatives… and we will see other ways that we can pursue,” he added. “I know that we can manage one way or another.”

    During country statements made on Sunday afternoon, which were closed to the media, there had been expectations that China might step up to close the gap, but that did not happen.

    The United Arab Emirates, Germany and other European nations are substantial government donors to IRENA, although the agency’s core budget has barely risen since 2018, documents show. That has limited its ability to expand its activities even as demand rises across developing countries and small island states for greater technical and policy support to boost renewables.

    La Camera noted that, following the US decision to pull out under Donald Trump, IRENA’s council may need to propose amendments to its approved budget for 2026-2027 ahead of its next meeting in May.

    Melford Nicholas, minister of information technologies, utilities and energy for Antigua and Barbuda, who is also a newly elected vice president of IRENA, told Climate Home News the US move would “not be an insignificant development” but Europeans had indicated they could help make up the shortfall.

    Clean energy for “opportunity and necessity”

    At the opening session of the two-day assembly, La Camera and other top officials affirmed the importance of renewable energy as the best choice for energy and economic security at a time of rising geopolitical tensions driven by fossil fuel interests.

    Selwin Hart, special adviser to the UN Secretary-General on Climate Action and Just Transition, said the world is clearly changing its energy system to clean sources “not out of idealism, but out of opportunity and necessity”.

    He noted that three out of four people live in countries that are net importers of fossil fuels, exposing them to geopolitical shocks, volatile prices and balance of payment pressures.

    Examples of this include the rise in gas prices in Europe after Russia’s invasion of Ukraine in 2024 led to sanctions.

    “The energy transition is taking place… not only based on climate considerations, but based on costs, based on competitiveness and energy security and energy independence,” Hart added. “These are the driving forces now – hardcore economic, hardcore national security [and] strategic reasons.”

    In a video message, Annalena Baerbock, president of the UN General Assembly and former foreign minister of Germany, said “we are living in heavy, challenging times” – but despite setbacks and political headwinds, “the march to a renewable energy future has proven unstoppable”.

    She added that global renewable capacity has now reached more than 4,400 gigawatts, almost 30 times that of 2015 when the Paris climate agreement was adopted, while a record $2.4 trillion was invested in the energy transition in 2024. “There is no way back,” she added.

    However, she and Hart both noted that more needs to be done to support African countries to unlock finance for clean energy, as it lags far behind other regions and receives only around 2% of investment in the sector.

    Challenges for small island states

    The substantial needs of small island developing states (SIDS) are also front and centre at the IRENA Assembly, where ministers have discussed the challenges of shifting away from costly diesel and other polluting fuels while being exposed to rising climate shocks such as destructive cyclones.

    Antigua and Barbuda’s minister Nicholas pointed to the difficulty of gaining insurance for renewable energy facilities as a key barrier in an era when storms can cause huge damage.

    This happened in Barbuda in 2017 when Hurricane Irma wiped out a solar plant that was not insured. Governments including the United Arab Emirates and New Zealand helped to rebuild it.

    Nicholas said SIDS are still in need of concessional finance, which could “become increasingly challenging for us” in the current international environment.

    “It’s an issue, because that retards the speed at which we’re able to get to renewable energy transition,” he added, noting his country is likely to reach an energy mix of around 60% renewables by 2030 rather than the 100% it had aimed for.

    Despite the obstacles, ministers from Caribbean countries like St Kitts and Nevis and Dominica showcased examples of planned geothermal plants that will enable them to phase down fossil fuels dramatically.

    IRENA’s La Camera said he was optimistic the world would get very close to realising a global goal of tripling renewable energy capacity by the end of this decade, but was still lagging behind on a twin target of doubling energy efficiency by 2030.

    To help catalyse a global transition away from fossil fuels, he added that IRENA would work with COP host nations on a roadmap to that end, which they are due to present at the COP31 UN climate summit in Turkey in November, as well as a potential target for electrification consistent with that plan.

    Renewables create fewer jobs globally as energy transition enters “new phase”

    Published

    on

    Jobs in renewable energy expanded only slightly in 2024 to reach 16.6 million worldwide, new figures show, suggesting that the industry’s ability to create employment is slowing as it matures.

    According to an annual report from the International Renewable Energy Agency (IRENA) and the International Labour Organization (ILO), the number of renewables jobs rose by just 2.3% between 2023 and 2024. This was partly due to Chinese solar manufacturers already producing more components than they could sell, and laying off workers to cut costs.

    Other factors included a shift from rooftop solar installations to utility-scale systems in major markets like India and Germany, as well as increasing automation in the sector – a trend that is expected to accelerate with the use of robots, drones and artificial intelligence.

    Employment in the sector has risen steadily from 7.3 million in 2012, when the data series began, along with the increase in solar, wind and geothermal energy, hydropower and biofuels around the world. But far fewer new jobs were created in 2024 – 400,000 – compared with 2023, which saw a jump of 2.5 million.

      In a foreword to the report released on Sunday, IRENA Director-General Francesco La Camera and ILO Director-General Gilbert F. Houngbo wrote that the slowdown in the rate of job creation points to “the emergence of a new phase in the energy transition”.

      “Growing automation and economies of scale mean that comparatively less human labour is required for each new unit of capacity – although impacts vary across countries, technologies and segments of the renewable energy value chain,” they said.

      IRENA currently projects that, with the right policies in place, the renewable energy workforce could expand to 30 million jobs by 2030. But the latest figures – which do not reflect the impact of Donald Trump’s squashing of US renewables incentives in 2025 – indicate reaching that level could be a stretch.

      Michael Renner, IRENA’s head of socioeconomics and policy, told Climate Home News on the sidelines of the agency’s assembly in Abu Dhabi that, in the past 10-20 years, the renewable energy sector has been far more labour-intensive than the fossil fuel industry – which has largely been automated – but the difference is starting to narrow.

      “I think renewables are still looking favourable [for job creation], and I don’t think that advantage will be lost – but I think it will be less massive, less dramatic,” he added.

      Notes:
      a) Includes liquid biofuels, solid biomass and biogas.
      b) Direct jobs only.
      c) “Others” includes geothermal energy, concentrated solar power, heat pumps (ground based), municipal and industrial waste,
      and ocean energy.

      Geographical imbalances

      The world needs to add a huge amount of solar, wind, hydro and geothermal capacity to meet a global goal of tripling renewable power capacity to reach 11.2 terawatts (TW) by the end of the decade. That will require installing an average of about 1.1 TW each year from 2025 to 2030, which is about double the power added in 2024, IRENA says.

      In a statement on the jobs report, La Camera noted that renewable energy deployment is “booming, but the human side of the story is as important as the technological side”.

      He pointed to geographical imbalances in the deployment of clean energy and related job creation. Africa has particularly struggled to attract foreign investment in building out renewables, with much of the growth currently concentrated in Asia.

      Outdated geological data limits Africa’s push to benefit from its mineral wealth

      “Countries that are lagging behind in the energy transition must be supported by the international community,” La Camera said. “This is essential not only to meet the goal of tripling renewable power capacity by 2030, but also to ensure that socioeconomic benefits become lived realities for all, helping to shore up popular support for the transition.”

      Some countries like Nigeria are trying to boost their solar equipment manufacturing supply chains, with the government saying it plans to ban solar panel imports, and two large assembly plants announced to support public electrification programmes.

      China leads on jobs but solar stumbles

      In 2024, China was home to nearly half – 44% – of the world’s renewable energy jobs with an estimated 7.3 million. But in that year, employment in its solar photovoltaics (PV) sector actually contracted slightly, as five leading manufacturers cut their workforce.

      This was in response to efforts by the Chinese government to curb what it has dubbed “disorderly” competition by reducing excess capacity across the solar PV supply chain, in a bid to boost prices and product quality.

      Renewables jobs stayed flat in the European Union in 2024, meanwhile, at 1.8 million jobs, and India and the US saw small rises, accounting for 1.3 million and 1.1 million respectively. Brazil was also a big employer, with 1.4 million jobs, partly thanks to its biofuels industry based on soy and sugarcane.

      Trump to pull US out of UN climate convention and climate science body

      On the impact of Trump’s efforts to roll back incentives and subsidies for green energy in the US, Renner said it will likely mean fewer new renewable power installations, with the report documenting examples of solar and wind projects that were cancelled or halted in 2025.

      He also noted the dampening effects of US tariff hikes on the production of solar panels in Southeast Asia, which has led to job losses in some countries including Thailand, while others such as India have been able to increase their exports to the US thanks to relatively lower taxes on their exports.

      Limited opportunities for women and people with disabilities

      The report also highlights a lack of progress on increasing women workers in the renewables industry. While higher than in fossil fuels, it has plateaued at about one job in three.

      Those jobs are concentrated in administrative roles, which account for 45% of female employment in renewable energy, as well as in technical positions unrelated to science, technology or engineering, such as legal work.

      The report calls for greater efforts by companies, education and skills training bodies to open up more opportunities for women in clean energy, as well as for people with disabilities who face high barriers to participating in labour markets across the board, with only three in 10 being employed worldwide.

      There are some positive cases where proactive policies have made a difference, such as in India’s electric vehicle industry, which has a relatively high level of women at the management level.

      How Belém launched the Just Transition mechanism

      In Brazil, meanwhile, national legislation requires companies with more than 100 employees to reserve 2-5% of jobs for people with disabilities, including those in renewable energy.

      And in Spain, energy utility Endesa and municipalities trained over 300 people with intellectual and psycho-social disabilities in tasks like vegetation management and composting at solar energy sites, with nearly 40% securing jobs after six months.

      ILO’s Houngbo called for greater efforts on disability inclusion in the clean energy transition, not just as a matter of justice but also to advance resilient labour markets and sustainable development.

      “This requires accessible training systems, inclusive hiring practices, and workplaces that accommodate, welcome and respond to diverse needs and respect every worker’s rights,” he added.

      Climate Home News received support from IRENA to travel to Abu Dhabi to covers its 16th Assembly.
