Net negativity
Demonstrating evidence of removing atmospheric carbon dioxide on a lifecycle basis.
Scientific verification
Independently reviewed by our third-party scientific advisors and/or verified by standards.
Social and environmental benefits
Avoiding and minimizing environmental and social harm while supporting social equity and sustainability.
Low-durability solutions
Forestry and soil-based projects are typically durable for up to 100 years and represent high volume potential in the short term. We will prioritize projects that demonstrate clear calculations and methodologies.
Medium-durability solutions
Biochar and other types of carbon dioxide utilization sequester carbon for 100 to 1,000 years. We will prioritize projects that provide a full lifecycle analysis, adhere to best practices in feedstock and disposition, and avoid any human health hazards.
High-durability solutions
Direct air capture, biomass carbon removal and storage, and mineralization have durability terms of greater than 1,000 years. We will prioritize projects with responsible storage, monitoring strategies, and full lifecycle assessments.
