How It Works

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)

  • Temperate forests: 1.5-3.5
  • Tropical forests: 3-8
  • Grasslands: 0.5-1.5
  • Agricultural soil (cover crops): 0.3-1.0
  • Formula

    Annual Sequestration = Area (acres) * Rate (tons CO2/acre/year)

    Worked Example

    A 100-acre temperate forest sequestering 2.5 tons CO2/acre/year over 10 years.

    area_acres = 100seq_rate = 2.5years = 10
    1. 01Annual sequestration: 100 * 2.5 = 250 metric tons CO2/year
    2. 02Total over 10 years: 250 * 10 = 2,500 metric tons CO2
    3. 03Per acre total: 2,500 / 100 = 25 tons/acre

    Frequently Asked Questions

    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.
