Direct Air Capture (DAC)
Technology that uses specialized machines to capture CO₂ directly from ambient air. Often combined with permanent geological storage for high-permanence carbon removal.
Why direct air capture (dac) matters for carbon credit buyers
DAC is the most measurable form of carbon removal: machines meter exactly how much CO₂ they capture, and geological storage keeps it locked away for thousands of years. That precision and durability make DAC credits a cornerstone of high-integrity net-zero portfolios, though supply is limited and prices are the highest in the market. Costs are expected to fall as plants scale.
