ARIA: The UK’s dubious ‘deep tech’ agency
In 2025 a new ‘high risk-high reward’ agency funded by the UK Government began bankrolling outdoor solar geoengineering experiments, in direct contravention of agreed international moratoria and norms. ETC Group decided to take a closer look. High risk ‘deep tech’...
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...
Technology and Geoengineering Map updates
Artificially fertilising the ocean in order to sink carbon as a climate solution is gathering momentum
This update on Ocean Fertilisation and Artificial Upwelling summarises the latest developments on the Geoengineering Monitor Map, highlighting new trends for civil society and climate justice movements to follow in their efforts to oppose geoengineering globally. ...
Weak voluntary certification and flawed carbon accounting are legitimising the biochar boom
This technology update on biochar summarises the latest developments on the Geoengineering Monitor Map, highlighting new trends for civil society and climate justice movements to follow in their efforts to oppose geoengineering globally. It was researched and written...
Geoengineering the stratosphere: Funding for high-altitude geoengineering research is increasing massively
This update on Stratospheric Aerosol Injection (SAI) summarises the latest developments on the Geoengineering Monitor Map, highlighting new trends for civil society and climate justice movements to follow in their efforts to oppose geoengineering globally. This...

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,...

Institutionalising Article 6: Bureaucracy, Technology, and the Future of Global Carbon Markets
Guest article by Tamra L Gilbertson As the UNFCCC mid-term process drew to a close in Bonn, Germany, the overall picture was difficult to ignore. Major areas of negotiation, including the Global Goal on Adaptation and the Mitigation Work Programme, ended without...
How does it feel? Reflections on a community’s struggle to protect its coastline from marine geoengineering
By Senara Wilson Hodges, Keep Our Sea Chemical Free and The Cornwall Carbon Scrutiny Group How does it feel to sink your bare feet into the sparkling ocean? To stand silently with people who love this bay and have fought to protect it? To close your eyes and to feel...
Sun-dimming is the new climate colonialism, and the UK is funding the runway
Guest article by Mohammed Usrof, Palestinian Institute for Climate Strategy Solar geoengineering is moving from academic debate into political infrastructure. It is being advanced as a security and profit project for a world that refuses to phase out fossil fuels and...
