Annual CO2 Sequestered vs Time Period
公式
How to Calculate Carbon Sequestration
Carbon sequestration is the process of capturing and storing atmospheric CO2 in plants, soil, and geological formations.
Typical Rates (tons CO2/acre/year)
Formula
Annual Sequestration = Area (acres) * Rate (tons CO2/acre/year)
计算示例
A 100-acre temperate forest sequestering 2.5 tons CO2/acre/year over 10 years.
- 01Annual sequestration: 100 * 2.5 = 250 metric tons CO2/year
- 02Total over 10 years: 250 * 10 = 2,500 metric tons CO2
- 03Per acre total: 2,500 / 100 = 25 tons/acre
常见问题
What is carbon sequestration?
Carbon sequestration is the long-term capture and storage of atmospheric CO2. Natural sinks include forests, soil, and oceans. Engineered solutions include direct air capture and carbon mineralization.
How do forests sequester carbon?
Trees absorb CO2 through photosynthesis, storing carbon in trunks, branches, roots, and leaves. Forest soil also accumulates carbon from decomposing organic matter.
Is soil a significant carbon sink?
Yes, the world's soils hold about three times more carbon than the atmosphere. Regenerative agriculture practices can increase soil carbon storage by 0.3-1.0 tons CO2/acre/year.
