Explainer: Why gas plays a minimal role in China’s climate strategy

Carbon Neutral Regulation in AI Training

Ten years ago, switching from burning coal to gas was a key element of China’s policy to reduce severe air pollution. However, while gas is seen in some countries as a “bridging” fuel to move away from coal use, rapid electrification, uncompetitiveness and supply concerns have suppressed its share in China’s energy mix. As such, […]

Every year, understanding of climate science grows stronger. With each new research project and published paper, scientists learn more about how the Earth system responds to continuing greenhouse gas emissions. But with many thousands of new studies on climate change being published every year, it can be hard to keep up with the latest developments. […]

To mark Clean Air Night (22 January), Healthy Air Scotland, a coalition of public health, transport and environmental charities is calling on the Scottish Government to address the public health impacts caused by domestic burning. The call from Healthy Air Scotland comes as the coalition launches its manifesto ahead of the Scottish election in May. […]

Local governments are leaders in the fight against climate change: they reduce community-wide greenhouse gas emissions, promote renewable energy resources, and otherwise advance climate mitigation and adaptation goals. But even as many local governments have already demonstrated their capability to tackle the climate crisis, state governments can hinder those efforts by preempting local laws. Today, […]

Choosing the “least expensive” healthy food options could cut dietary emissions by one-third, according to a new study. In addition to the lower emissions, diets composed of low-cost, healthy foods would cost roughly one-third as much as a diet of the most-consumed foods in every country. The study, published in Nature Food, compares prices and […]

MIT researchers have identified significant examples of machine-learning model failure when those models are applied to data other than what they were trained on, raising questions about the need to test whenever a model is deployed in a new setting. “We demonstrate that even when you train models on large amounts of data, and choose […]

Since its launch on January 20, 2018, the Silencing Science Tracker has been documenting government efforts to restrict and prevent scientific research, education, and the publication and use of scientific information. We are proud to announce the launch of an improved version of the Tracker—a tool more critical than ever as the second Trump administration […]

Hinkley Point nuclear power station construction in Somerset in 2022. The government’s review of nuclear delivery, published in November, is based on misleading advice, says new research published by The Wildlife Trusts, a federation of UK wildlife charities. Faulty evidence underpins the Prime Minister’s appraisal of “pointless gold-plating, unnecessary red-tape, well-intentioned, but fundamentally misguided environmental […]

Solar is still the principal success story of the energy transition, say the authors. Despite continued low-carbon technology investment and progress, shortfalls in project realization ahead of 2030 threaten to impact interim goals set by countries and companies in the path to reaching net zero by 2050, according to analysis from consulting firm McKinsey & […]

Nearly 100 UK newspaper editorials opposed climate action in 2025, a record figure that reveals the scale of the backlash against net-zero in the right-leaning press. Carbon Brief has analysed editorials – articles considered the newspaper’s formal “voice” – since 2011 and this is the first year opposition to climate action has exceeded support. Criticism […]

The world’s most biodiverse nation, Brazil, has belatedly published its UN plan for halting and reversing nature decline by the end of this decade. Brazil is home to 10-15% of all known species on Earth, 64% of the Amazon rainforest and it supplies 10% of global food demand, according to official estimates. It was among […]
