Total CO2 Sequestered

1,235.4 lbs

Annual Sequestration Rate

41.2 lbs/year
Total Carbon: 336 lbs Dry Biomass: 673 lbs

Expert Tip

A single tree can sequester up to 48 pounds (22 kg) of CO2 per year once mature. Protecting mature trees yields greater immediate climate benefits than planting saplings.

Calculation Methodology & Details

📐

Formula

Biomass W: if DBH < 11": W = 0.25 × DBH² × H; if DBH ≥ 11": W = 0.15 × DBH² × H DryWeight = W × 0.725 (hard) or 0.70 (soft) Carbon = DryWeight × 0.50 CO2 = Carbon × 3.6663

Total green biomass W (in lbs) is estimated based on DBH (in inches) and height H (in feet). Sequestration calculates the molecular conversion to CO2 (based on carbon's atomic weight 12 and oxygen's 16). Metric values are converted for calculation.

How Carbon Storage is Calculated

Foliage and wood density models compute carbon footprint profiles:

1

Provide Tree Dimensions

Enter the trunk Diameter at Breast Height (DBH) and total tree height.

2

Select Class

Choose deciduous (hardwood) or coniferous (softwood) tree type.

3

Calculate equivalents

Review total dry biomass, pure carbon storage, and equivalent CO2 weight sequestered.
