June 1, 2026 – The Climate Intervention Environmental Impact Fund (CIEIF; https://cieif.org/ ) is pleased to announce completion of its fifth round of US$75,000 grants towards environmental impact analysis for climate restoration projects.  

The recipients are:    

Carbizon (www.uantwerpen.be/en/staff/harun-niron_23841/research/) is a Belgian startup project based at the University of Antwerp. It proposes a high-intensity enhanced rock weathering (ERW) two-year field test in Muranga’a County in central Kenya, integrating crushed basalt with biochar and organic matter to create a functional soil building system while simultaneously quantifying durable inorganic carbon removal. 

Hourglass Climate (www.hourglassclimate.org) is a U.S. non-profit organization dedicated to independent science for the responsible development of marine carbon dioxide removal. CIEIF’s grant will aid Hourglass’s development of a potential field test to evaluate the carbon removal efficiency and environmental safety of mineral-based Ocean Alkalinity Enhancement (OAE) in New Zealand. The project would involve the nearshore release of approximately 2,000 tons of finely ground, locally-sourced rock.

Institute for Glacier Stewardship (IFGS; www.icepreservation.org) is a U.S. based nonprofit group focused on potential interventions in glaciers aimed at slowing their global warming-driven melting and the resulting sea level rise. The ultimate goal, several years at least away, will be Antarctica’s glaciers, but IFGS first proposes undertaking a pilot field test in Yakutat, Alaska. Funding provided by CIEIF will support an independent environmental impact assessment of the proposed basal anchoring intervention — the removing of subglacial water to increase basal friction and slow glacier flow. 

More details about all three projects are at cieif.org/current-grants. 

CIEIF also is announcing another round of three grants with award amounts of $75,000 each. The deadline for applications is December 1, 2026. Innovative climate intervention projects worldwide in need of funding for focused environmental impact assessment, impact modeling, and/or public-stakeholder outreach are encouraged to apply. Details of the strict eligibility requirements are at: cieif.org/what-we-do and cieif.org/guidelines-for-grant-applicants/ .
