Key points:
• CBD Decision X/33, 8 (w) on geoengineering remains valid and should be affirmed and strengthened.
• The potential impacts of geoengineering on biodiversity have been scarcely studied. Studies and policy recommendations on the impacts on biodiversity and associated livelihoods caused by any geoengineering intervention are, and should remain, under the mandate of CBD and its bodies.
• New research papers continue to demonstrate high risks and uncertainties associated with the full range of geoengineering proposals.
