Carbon Offset Calculator
Calculate the cost to offset your CO₂ emissions, equivalent trees needed, and flight equivalents.
How to Use the Carbon Offset Calculator
- Enter your CO₂ emissions in tons.
- Enter offset price per ton (default $15).
- Click Calculate to see cost, tree equivalents, and flight equivalents.
使用场景
- •Personal carbon footprint offsetting.
- •Business sustainability planning.
- •Event or travel carbon neutrality.
公式
Formula: Cost = CO₂ tons × price/ton. Trees = CO₂ kg / 22 kg/year. Flights = CO₂ / 0.255 tons/flight.
常见问题
What is a carbon offset?
A carbon offset is a reduction in greenhouse gas emissions elsewhere to compensate for emissions at one source, typically measured in tons of CO₂ equivalent.
What is the average carbon offset price?
Voluntary carbon market prices range from $5–$50/ton CO₂. Quality verified offsets typically cost $15–$30/ton.
How much CO₂ does a tree absorb?
A mature tree absorbs approximately 22 kg of CO₂ per year on average, though this varies greatly by species, age, and climate.
