Flight Carbon Offset Calculator
Calculate CO2 emissions from flights and see how many trees you'd need to offset them
// Emissions by Class
Business class emits ~3x economy (more space per passenger). First class can be 4x. Choose economy when possible — it's the greenest option per person.
// Common Routes
JHB-Cape Town: ~250kg CO2. JHB-London: ~2,500kg. JHB-New York: ~2,800kg. A single long-haul flight can equal months of driving.
// Tree Math
A mature tree absorbs ~22kg CO2/year. Offsetting one JHB-London return flight requires ~227 trees growing for a full year. Planting trees helps but isn't a complete solution.
// Reduce Impact
Fly direct (takeoff/landing use the most fuel). Choose newer aircraft. Fly economy. Consider trains for shorter routes. Offset through certified programmes.
