Geoengineering technologies and approaches
Geoengineering technologies and approaches broadly fall into two categories, Solar Radiation Modification (SRM) and Carbon Dioxide Removal (CDR).
Most are hypothetical proposals that exist only in research papers and modelling studies, others are already being tested and commercialised by various geoengineering advocates.
We are keeping close track of each of them – select a technology below to access more information about it, including the latest project updates and a printable briefing.
