Removals Basket
Carbon taken out of the air and kept out
Durable carbon dioxide removal only: biochar and enhanced rock weathering with century-to-millennia storage, independently audited on removal-native registries.
Removals is the premium end of the shelf and the only basket that contains no avoidance credits at all. Biochar locks plant carbon into a mineralised form that persists in soil for centuries; enhanced rock weathering accelerates the natural reaction that converts atmospheric CO2 into bicarbonate and stores it in the ocean for tens of thousands of years. Supply is genuinely scarce and priced accordingly, so availability here is small and refreshed as the desk contracts new issuances. Credits are drawn from Puro.earth, Isometric and Verra rather than from a single supplier.

Exactly what is in this basket
Every tonne you buy is split across these projects in the proportions shown. Each one links to its public registry listing, so you can verify any of it yourself.
Carbofex 1 Hiedanranta
Slow-pyrolysis biochar production in Tampere, Finland, audited by DNV and issuing CO2 Removal Certificates on Puro.earth under the Biochar 2022 methodology. The registry records 4,113 CORCs issued and 3,944 retired over a crediting period running from November 2018 to April 2022.

Registry listingProject Reignite: Turning Farm Waste into Climate Action
The first biochar project Verra registered under VM0044, in Odisha, India. Rural farmers stop open-burning agricultural waste and instead pyrolyse it into biochar, which is applied back to the same farms as a soil amendment.

Verra VCS · 4679
Registry listingERW Deployment: Seoni and North Chhattisgarh, India
Mati Carbon spreads Deccan Traps basalt powder on smallholder rice paddies, where high water fluxes speed up basalt dissolution and CO2 drawdown. Isometric assessed the reversal risk as no observable risk, so none of the credits are held in a buffer pool.

Registry listingUS Southeast Enhanced Weathering Project
Lithos Carbon applies superfine byproduct basalt dust from nearby quarries to farmland across the subtropical southeastern United States, working with both smallholders and large farms. Sourcing quarry byproduct locally keeps life-cycle emissions low.
