Carbon to trees and offset cost
Turn tonnes of CO2 into trees and money. Enter your footprint in tonnes. See roughly how many trees it would take, and what voluntary carbon credits would cost.

Tree counts are illustrative and based on US urban trees. In a desert climate, expect fewer tonnes per tree.
How we work it out
Trees: tonnes / (0.06 t per tree per year x years). The US EPA figure is a 10-year average for a medium-growth urban tree in the US, allowing for some trees dying. Offsets: tonnes x 2024 price per tonne from Ecosystem Marketplace (State of the Voluntary Carbon Market 2025), as reported by Environmental Finance and Insight Focus. QAR uses the fixed rate of 3.64 per USD.

Questions
How many trees offset 1 tonne of CO2?
Using the US EPA figure of 0.06 tonnes per urban tree per year, about 17 trees growing for one year, or about 1.7 trees growing for ten years. This is an illustration, not a planting plan.
Do trees work the same in Qatar?
No. The EPA figure is for trees in a temperate US city. In Qatar's heat and dry soil, trees grow slower and need irrigation, often with desalinated water that itself has a carbon cost. Real uptake here is likely lower.
How much does a carbon offset cost?
Ecosystem Marketplace reports an average voluntary credit price of about USD 6.34 per tonne in 2024. Prices ranged from about USD 6.03 for avoided deforestation to about USD 29.72 for blue carbon credits.
Are cheap offsets good offsets?
Not always. Some cheap credits have been criticised for overstating impact. Look for removal credits and well-known standards. Cutting your own emissions first is more reliable.
Should I offset or reduce?
Reduce first. Offsets are for what you cannot cut yet. Our other tools show where your biggest cuts are: AC, flights and food.
