DeBriefed 5 June 2026: UK eyes 2040 emissions cut | US ‘dismantling’ oceans research | China’s solar slump
Why this matters: environmental and climate reporting with long-term consequences.
Welcome to Carbon Brief’s De Briefed. An essential guide to the week’s key developments relating to climate change. This week UK proposes new emissions target ‘ON COURSE’: The UK government has proposed reducing the country’s greenhouse gas emissions to 87% below 1990 levels by 2040, reported the Associated Press. The newswire cited scientists saying that the goal “puts the UK on course to meet its 2050 net-zero target”. To meet this target, the UK would “need to invest around £880bn over 25 years…but doing so would yield benefits worth £1,620bn”, according to an in-depth analysis of the plans by Carbon Brief. UPCOMING ‘FLASHPOINT’: The Financial Times noted that, for the target to become “legally binding”, it must be approved by parliament. While the UK’s previous carbon budget “received cross-party support”, this time the proposal is “expected to become a flashpoint among lawmakers”, it added, with both the Conservatives and Reform pledging to “scrap” net-zero policies. DRIVING FORCE: Separately, a new report by consultancy Confederation of British Industry (CBI) Economics has valued the UK’s “net-zero economy” at more than £100bn a year, reported the Guardian. It added that, by a broad measure, the UK energy transition supports 1.1m jobs and provides “nearly 4% of the UK’s economic output”. US ‘dismantling’ oceans data SYSTEMS OFFLINE: The Trump administration is “dismantling” a “$368m deep-ocean observation system” that, among other things, allows scientists to monitor the ocean currents that affect the global climate and understand how the “ocean is absorbing greenhouse gases from the atmosphere”, said the New York Times. Bloomberg reported that Trump’s efforts to close the National Center for Atmospheric Research (NCAR), a key climate science research institution, has been “temporarily blocked” by a judge. RULE ROLLBACK: The US Securities and Exchange Commission (SEC), an independent body that regulates US securities markets, has proposed repealing the cl
