More than 300 people across academia and industry spilled into an auditorium to attend a BoltzGen seminar on Thursday, Oct. 30, hosted by the Abdul Latif Jameel Clinic for Machine Learning in Health (MIT Jameel Clinic). Headlining the event was MIT PhD student and BoltzGen’s first author Hannes Stärk, who had announced BoltzGen just a few days […]

Following the end of COP30, Carbon Brief’s journalist answered a range of questions exclusively asked by its Insider Pass holders. COP30 officially closed at 8:44pm on Saturday evening, with the final gavel coming down and more than 150 pages of decision text adopted at the summit in Belém, Brazil. Less than 24 hours later, Carbon […]

The 30th Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC) reached a disappointing conclusion on Saturday. Just a few days earlier, things had looked promising. The COP President—Ambassador André Corrêa do Lago of Brazil—had proposed a draft decision recognizing the need for countries to “overcome their dependence on […]

There is growing attention on the links between artificial intelligence and increased energy demands. But while the power-hungry data centers being built to support AI could potentially stress electricity grids, increase customer prices and service interruptions, and generally slow the transition to clean energy, the use of artificial intelligence can also help the energy transition. […]
Today the Sabin Center for Climate Change Law published a report analyzing climate change lawsuits filed in United States courts while President Joseph R. Biden was in office. During the Biden administration, the federal government reversed course on the first Trump administration’s climate deregulation and embarked on a “whole-of-government approach to combatting the climate crisis.” […]

From policy and regulation to innovation, operations and global markets, this year’s ADBA National Conference in London on 10 December will hold the essential discussions required to advance the UK’s biogas and biomethane sector and accelerate the transition to net zero, according to organizer the Anaerobic Digestion and Bioresources Association (ADBA). Organised under the theme […]

On the Isle of Skye, Waterstein Head comprises large structures of volcanic basalt, rich in silicate minerals that bond readily with CO2 to form stable carbonates. Rocks formed by ancient volcanoes found across the UK could safely store millions of tonnes of CO2 by turning it into stone, according to new research. Scientists have identified […]

This article contains sponsored content. By Matt Hale, Global Key Account Director, HRS Heat Exchangers Global emissions of carbon dioxide (CO2) from burning fossil fuels have risen again,1 according to data released during the COP 30 UN climate conference in Brazil. This underscores the ongoing challenges that the world faces in meeting previously agreed reductions […]

A voluntary plan to curb fossil fuels, a goal to triple adaptation finance and new efforts to “strengthen” climate targets have been launched at the COP30 climate summit in Brazil. After all-night negotiations in the Amazonian city of Belém, the Brazilian presidency released a final package termed the “global mutirão” – a name meaning “collective […]

There’s been a lot of chatter about Roadmaps in Belem. The WWF and Greenpeace have led a call for a roadmap to end deforestation. Currently, 45 countries have indicated support. More than 80 countries have called for a roadmap to phase out fossil fuels. Additionally, there are four other roadmaps on finance from developed to […]
I’m writing this from Boston, not Belém. I left COP30 a day before it ended—exhausted, frustrated, and strangely hopeful all at once. Brazil’s presidency pushed hard to close the deal, with President Lula returning to witness what they hoped would be a historic finish. Draft texts circulated rapidly. But negotiators were still debating language that […]

Welcome to Carbon Brief’s DeBriefed. An essential guide to the week’s key developments relating to climate change. This week Key ‘mutirão’ text emerges ‘MUTIRÃO’ 2.0: After many late nights, but little progress – and a dramatic fire at the COP30 venue – the much-awaited second draft of the summit’s key agreement, called the “mutirão” text, finally […]
It is a basic principle of administrative law that, even after a jurisdiction enacts legislation, full implementation of the law typically depends on regulatory and other actions by executive branch agencies. This is particularly true in the context of environmental and climate change legislation, which are often especially complex and generally demand considerable administrative and […]

In many cases, industrial composting has been required to break down biopolymers. Biodegradable plastics are emerging as an alternative to conventional plastics to address microplastic pollution. Unlike conventional plastics, biodegradable plastics are designed to break down over a faster timescale under specific conditions, potentially reducing long-term persistence in the environment. Although regulations are driving the […]
