High-impact carbon removal pathways

We connect buyers with early-stage carbon removal projects across six

impact-drive and nature-powered and hybrid pathways.

ARR focuses on planting new forests, restoring degraded forests, and enhancing vegetation cover. These activities absorb CO2 from the atmosphere and improve biodiversity.

Biochar is a form of charcoal produced from organic waste through pyrolysis. It sequesters carbon in a stable form and enriches soil, enhancing crop yields and soil health.

Blue carbon refers to the carbon captured and stored by coastal and marine ecosystems, primarily mangroves. Mangroves sequester significant amounts of CO2, provide critical coastal protection and support biodiversity.

ERW accelerates the natural process of mineral weathering to capture CO2 from the atmosphere. The process involves spreading finely ground minerals that react with CO2, forming stable carbonates.

Soil carbon sequestration involves practices that increase the amount of carbon stored in soils. These practices improve soil health and fertility while removing CO2 from the atmosphere.
