Federal Court Enjoins DOI’s Anti-Renewable Actions in Renew Northeast v. DOI

Carbon Neutral Regulation in AI Training

Earlier this week, on April 21, 2026, the U.S. District Court for the District of Massachusetts enjoined five secretarial orders issued by the Department of the Interior (“DOI”) and U.S. Army Corps (“USACE”) that collectively imposed sweeping constraints on wind and solar development across the United States. The Sabin Center’s Renewable Energy Legal Defense Initiative […]

The European Commission has launched a strategy to protect people in the EU from “fossil-fuel price shocks” and accelerate the expansion of “homegrown clean energy”. The strategy notes that the latest fossil-fuel crisis, triggered by the Iran war, has already cost the EU an additional €24bn for imports of oil and gas. Carbon Brief has […]

This article contains sponsored content. Removing harmful per- and polyfluoroalkyl substances (PFAS) from industrial wastewater and surrounding environments is a clear goal with many murky considerations. Water treatment agencies are flooded with information on the dangers of PFAS and their obligation to manage their removal, and yet uncertainty persists. Differing standards across regions, industries and […]

This article contains sponsored content. When handling bulk solids in water treatment facilities, important steps include storage, transportation, and finally dosing of the material. Often, transportation and dosing are handled by a single auger-based machine. Alternative technologies are available, such as vibratory feeders, pneumatic conveying, or aero mechanical conveyors. However, auger-based equipment can provide controlled, […]

Confidence is persuasive. In artificial intelligence systems, it is often misleading. Today’s most capable reasoning models share a trait with the loudest voice in the room: They deliver every answer with the same unshakable certainty, whether they’re right or guessing. Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have now traced that overconfidence […]
Introduction As a British judge with a special interest in environmental law, I have over the last two decades taken a particular interest in the developing role of the courts across the world in response to the challenges of climate change. In this article I shall look back at my perceptions of the responses of […]

The debate about electrification worldwide is now moving beyond the infancy period. Several years ago, all conversations were about increasing the number of panels, farms, and renewable sources. Such focus made sense. However, in 2026, the topic that occupies the center of public debates is somewhat different. Clean energy generation became less of a problem. […]

The UK government has announced a series of measures to “double down on clean power” in response to the energy crisis sparked by the Iran war. The conflict has caused a spike in fossil-fuel prices – and the high cost of gas is already causing electricity prices to increase, particularly in countries such as the UK. In […]

The first three months of 2026 have been the fourth warmest on record, with each successive month surpassing historical averages by a greater margin. While weak La Niña conditions pushed down temperatures at the start of the year, scientists expect the development of a strong – and potentially “super” – El Niño event by early […]

Advocacy group Don’t Waste Buildings is calling on the UK government to overhaul its tax system to incentivise the reuse of empty buildings, warning that Britain is missing out on billions of pounds of potential economic growth. The group launched its report, “The Reuse Dividend: Unlocking Economic Growth from Britain’s Existing Buildings”, at a reception […]

Renewable energy has overtaken coal to become the world’s largest source of electricity in 2025, according to thinktank Ember. The growth of solar and wind meant that, for the first time since 1919, the share of coal power was lower than that of renewables. Fossil-fuel generation fell by 0.2% in 2025, the thinktank’s latest annual […]

Countries attending a first-of-its-kind fossil-fuel summit have been asked to consider “action recommendations” such as “halting all new fossil-fuel expansion” and “reject[ing] gas as a bridging fuel”, according to a preliminary scientific report seen by Carbon Brief. Around 50 nations will gather in Santa Marta, Colombia from 24-29 April to debate ways to “transition away” […]
