Trees absorb carbon dioxide through photosynthesis, removing greenhouse gas from atmosphere. Absorption rates vary by species, age, and climate.
ステップバイステップガイド
- 1Mature hardwood trees absorb 20-48 kg CO₂/year on average
- 2Young trees absorb less; mature trees at peak absorption
- 3Total lifetime absorption: one mature tree ≈ 20-30 tonnes CO₂
解いた例
入力
100 mature trees, average 30 kg CO₂/tree/year
結果
3 tonnes CO₂ absorbed annually
Meaningful but modest offset
避けるべきよくある間違い
- ✕Over-estimating tree absorption capacity
- ✕Planting trees in marginal soils with poor survival
よくある質問
How many trees offset a person's carbon footprint?
Typical person generates 4-16 tonnes CO₂/year; requires 100-500+ trees for complete offset.
Do trees absorb carbon forever?
No, carbon stored until tree dies. Forest management extends storage; sustainably harvested wood maintains benefit.
