Who Funds and Who Pays: The funding of solar geoengineering, 2020–2025
This report by Jared Sanborn and J. P. Sapinski, published by the Heinrich Böell Foundation, analyses the period from 2020 to 2025, and shows that funding for high-risk solar geoengineering technologies has increased dramatically - more than tenfold. Both 2024 and...
Global Southwashing: How The Degrees Initiative is imposing its solar geoengineering agenda onto climate research in the Global South
This briefing by Anja Chalmin, a researcher with Geoengineering Monitor and the ETC Group, examines The Degrees Initiative, a UK-based NGO that is “dedicated to putting the Global South at the centre of the Solar Radiation Modification (SRM) conversation.” Contents...
New briefing offers a critical perspective on biochar
Biofuelwatch's new briefing, Biochar: A critical perspective, looks into what the science tells us about whether biochar reliably stores carbon and boosts soil fertility. Download the briefing In 2011, Biofuelwatch published a comprehensive report on biochar:...

The Seaweed Delusion: Industrial seaweed will not cool the climate or save nature
As the world scrambles for a climate fix, seaweeds – or “macroalgae” – have been thrust into the limelight. Buoyed up by hype and hundreds of millions of dollars of so called “green” investment, a new “blue carbon” seaweed industry is invading coasts and seas,...
Carbon Capture or Captured Futures? New Report From Biofuelwatch on California Climate Politics
New Report from Biofuelwatch Exposes Sordid Workings of California Climate Politics While California state authorities continue to promote markets-based and technological approaches to advance ‘net zero’ as a primary focus for climate policy, grassroots organizations...
