Suppliers

A supplier is an organization focused on achieving carbon dioxide removal (CDR). They can be grouped into pathways based on capture and storage mechanisms. Scientists at Isometric work with multiple suppliers across pathways to advance research and to both review and develop protocols.
Biomass Carbon Removal and StorageBiomass carbon removal and storage (BiCRS) involves storing carbon present in biomass, which is organic material originating from living or recently living organisms.

Enhanced WeatheringEnhanced weathering (EW) refers to the acceleration of natural chemical weathering, a process in which carbon dioxide dissolved in rainwater reacts with minerals contained within rocks, partly dissolving them and producing stable bicarbonate ions. When these bicarbonate ions are transported to the oceans via rivers they may be securely stored on long-term timescales. Typically enhanced weathering involves spreading crushed reactive rocks or minerals on croplands.+2

MineralizationMineralization involves the conversion of carbon dioxide into stable mineral forms, such as carbonates. The process can occur naturally, over geological timescales, and through accelerated processes, such as enhanced weathering (EW). Within this process, metal oxides, such as magnesium oxide and calcium oxide, react with carbon dioxide to form stable carbonates phases. The products of this process are typically stable over geological timescales. Multiple process paths can be utilized to achieve mineralization, including biological, microbial, chemical and physical feedstock alteration.

ReforestationReforestation (Refo) involves activities that reintroduce or increase forest cover on degraded lands restoring the native forest ecosystem. Forests can act as a source or sink of carbon by converting atmospheric CO₂ into biomass through photosynthesis. Carbon is also steadily released from forest biomass through respiration and oxidation or as a result of timber harvesting, fires and deforestation. Reforestation activities include planting tree seedlings, facilitating natural regeneration and the ongoing management of the forest to maximize and preserve the carbon removed from the atmosphere that is stored in tree biomass.
