The Carbon Brief Quiz 2026

Carbon Neutral Regulation in AI Training

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 […]

Welcome to Carbon Brief’s DeBriefed. An essential guide to the week’s key developments relating to climate change. This week Iran war fallout continues WORK FROM HOME: The International Energy Agency has advised its member countries to take 10 steps in response to the ongoing energy crisis fuelled by the Iran war, including reducing highway speeds and […]

Just 1% of England’s land will be needed for renewables to help meet the UK’s climate goals by 2050, according to a first-of-its-kind framework. There is enough land in England to meet climate and nature goals, while also producing more food and building new homes, according to the UK government’s new “land-use framework”. Speaking at […]

Who benefits from artificial intelligence? This basic question, which has been especially salient during the AI surge of the last few years, was front and center at a conference at MIT on Wednesday, as speakers and audience members grappled with the many dimensions of AI’s impact. In one of the conferences’s keynote talks, journalist Karen […]

Sustainability in manufacturing usually gets brought up in terms of energy use, emissions and recycling, but let’s be clear – all that matters too – although a lot of waste is actually locked in right from the get-go, during the design phase. Before a system so much as gets built, turned on or put into […]

Most people think of waste as something physical. Plastic packaging. Food scraps. Old electronics. Piles of paper that should have been recycled weeks ago. Digital waste feels different because it is harder to see. A bloated video file does not sit on the kitchen counter. Ten duplicate exports do not spill out of a bin. […]

Methane, a potent greenhouse gas, is responsible for about 30% of the global temperature increase observed since the industrial revolution. China accounts for more than 10% of annual global human methane emissions, in large part due to unintended releases – known as “fugitive” emissions – from its energy sector. In a recently published study, we take […]

Large language models (LLMs) can generate credible but inaccurate responses, so researchers have developed uncertainty quantification methods to check the reliability of predictions. One popular method involves submitting the same prompt multiple times to see if the model generates the same answer. But this method measures self-confidence, and even the most impressive LLM might be […]

MIT researchers have spent more than a decade studying techniques that enable robots to find and manipulate hidden objects by “seeing” through obstacles. Their methods utilize surface-penetrating wireless signals that reflect off concealed items. Now, the researchers are leveraging generative artificial intelligence models to overcome a longstanding bottleneck that limited the precision of prior approaches. […]

Ion-exchange membrane process for chlor-alkali electrolysis. A new recycling initiative aims to convert pure titanium scrap generated during the manufacturing of electrolysis cells into a raw material for pure titanium. The approach is designed to reduce the environmental impact of cell production and enhance the value of recovered materials. It has been launched by Asahi […]
