How does the Tree Carbon Calculator work?

Mature hardwood trees absorb 20-48 kg CO₂/year on average Then: Young trees absorb less; mature trees at peak absorption Then: Total lifetime absorption: one mature tree ≈ 20-30 tonnes CO₂.

Can you give an example of how to use the Tree Carbon Calculator?

Example: Input 100 mature trees, average 30 kg CO₂/tree/year gives a result of 3 tonnes CO₂ absorbed annually (Meaningful but modest offset).

Is the Tree Carbon Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
