Tree Calculator
Tree Planting Carbon Calculator
Trees are one of nature’s most effective carbon capture tools. Through photosynthesis, trees absorb CO₂ from the atmosphere and store it as biomass. This calculator helps you understand how many trees would be needed to offset your carbon emissions, and how tree planting compares to carbon credit offsets.
How Many Trees to Offset Your Emissions?
UK average: ~5.5 tonnes per person. Use our Carbon Calculator to find yours.
Gift trees, grow a forest together

Trees are a lovely bonus. A subscription is what actually offsets your footprint, verified, certificated, and tracked on your dashboard.
How Much CO₂ Does a Tree Absorb?
The carbon absorption of a tree depends on its species, age, location, and growing conditions. On average:
- A young tree (1-10 years) absorbs approximately 5-10 kg CO₂ per year as it establishes its root system and canopy.
- A mature broadleaf tree absorbs approximately 22 kg CO₂ per year.
- Over its 40-year lifecycle, a single tree absorbs roughly 0.9 tonnes of CO₂ in total.
- UK native species such as oak, birch, and Scots pine are among the best for long-term carbon storage.
Trees vs. Carbon Credits
Both tree planting and carbon credit offsets play important roles in fighting climate change, but they work differently:
- Tree planting takes 20-40 years to deliver its full carbon benefit and carries risks (fire, disease, drought). Best for long-term legacy.
- Verified carbon credits represent emission reductions that have already occurred or are guaranteed. They deliver immediate climate impact.
The most effective approach combines both: offset your current emissions immediately with carbon credits, and plant trees for long-term environmental benefit.
