Grid Edition
Calcite — Permanent Carbon Removal · Iceland
We turn carbon into stone.

A permanent carbon-removal company, rebuilt as a verification document. The tonnes-removed figure leads, every claim carries a standard, and mineralization is a blueprint. CONCRETE Edition — Swiss precision for a climate mission.
Calcite captures CO₂ from the air and turns it to stone in Icelandic basalt — permanent for over a thousand years.
The site proves what the category usually only evokes: a tonnes-removed monument, an MRV table (permanence, leakage, net-efficiency, standard), a mineralization blueprint with per-stage timing, and transparent $/tonne pricing.
The grid is visible, the annotations are audited, and the dual funnel routes corporate buyers to offtake and partners to advance commitments. The measurement aesthetic, applied to a mission.
Before the rebuild.
A durable carbon-removal company with verifiable permanence and a site built on drone footage of green hills and “join the net-zero journey.” Sustainability leads found no permanence figure, leakage number, or verification standard. The science was rigorous; the page was a brochure.
Offtake inquiries up 300%. Showing permanence beat promising it — in the one category where the buyer audits the method.
