We’re asking the tough questions.
Our due diligence model uses a rigorous set of criteria to vet the highest quality carbon removal solutions. As a result, our solutions are scalable, permanent, and meet stringent quality and MRV standards.
Our carbon removal solutions
Direct Air Capture
Direct Air Capture
Our direct air capture (DAC) technology removes CO₂ from ambient air. Powered by low-carbon energy, air is drawn into collector containers, and CO₂ molecules are captured inside with the sorbent. Once saturated, the CO₂ is released with low heat and transferred for storage safely and permanently underground.
Co-benefits
Highly scalable, uses a small land footprint, and creates jobs in varied locations.
Durability
10,000 years
Afforestation/Reforestation
Afforestation/Reforestation
Reforestation uses the natural ability of trees to absorb CO₂ through photosynthesis, storing carbon in their biomass and the surrounding soil.
Co-benefits
Supports biodiversity, stabilizes local climates, prevents soil erosion, and creates economic opportunities in forestry.
Durability
40+ years
Biochar
Biochar
Biochar offers another versatile solution for carbon removal. Produced by thermally decomposing biomass under low-oxygen conditions, Biochar locks carbon into a stable form that can be integrated into soils.
Co-benefits
Enhances soil fertility, improves water retention, reduces emissions of methane and nitrous oxide from agricultural soils, and creates a circular economy for organic waste.
Durability
10,000 years
Mangroves
Mangroves
Mangroves are coastal ecosystems composed of salt-tolerant trees and shrubs that capture and store carbon through both biomass and sediment accumulation. Their dense root systems trap organic material, enabling long-term carbon sequestration while stabilizing coastlines and reducing erosion. Mangroves are especially effective in sequestering "blue carbon," the carbon stored in coastal and marine ecosystems.
Co-benefits
Protects coastal communities from storm surges and flooding, enhances biodiversity by providing critical habitats for fish and wildlife, and supports livelihoods through fisheries and eco-tourism.
Durability
10,000 years
Bioenergy with carbon capture & storage
Bioenergy with carbon capture & storage
BECCS combines renewable energy generation with negative emissions by utilizing biomass to take up CO₂ during growth. This biomass is then processed for energy, and the resulting CO₂ emissions are captured and stored deep underground in geological formations.
Co-benefits
Provides a renewable energy source (using organic matter from plants to produce energy).
Durability
10,000+ years
Enhanced rock weathering
Enhanced rock weathering
Enhanced Rock Weathering accelerates natural chemical processes by spreading finely crushed silicate rocks over land. These rocks react with atmospheric CO₂ to form stable bicarbonates or carbonates that remain sequestered for thousands of years.
Co-benefits
Improves soil health (increasing crop yields for farmers), contributes to ocean alkalinity by mitigating acidification when dissolved minerals enter water bodies.
Durability
1,000+ years
