Carbfix
72Credible Contributor· ProvisionalIcelandic company that permanently mineralises CO₂ by dissolving it in water and injecting it into basaltic rock, where it solidifies into stone within two years rather than millennia.
Why it's on ClimateTicker
Carbfix is a genuine deep-decarbonisation infrastructure company whose core product — permanently mineralising CO₂ into stone inside basaltic rock — is one of the most durable and scientifically credible carbon removal pathways in existence, validated by peer-reviewed science and independently certified by DNV. The technology directly removes or sequesters CO₂ rather than merely offsetting it, giving it a materially higher integrity profile than most carbon-market players. The key honest caveat is that current injection volumes remain modest relative to global needs, SBTi/CDP disclosures for Carbfix's own operational footprint are not publicly confirmed, and the company is still scaling from pilot to commercial megaton-class operations.

Controversy & Greenwashing Watch
The process requires approximately 25 tonnes of freshwater per tonne of CO₂ injected, raising sustainability concerns about water use at scale, though Carbfix is actively researching seawater substitution.source ↗
Despite operating as a climate company, Carbfix has no publicly identifiable SBTi-validated targets or CDP questionnaire response for its own operational footprint, a gap relative to investor-grade ESG disclosure standards.source ↗
