When you fly, your seat on the plane is responsible for a specific share of the fuel burned and the CO2 released. Carbon offsetting a flight means calculating that CO2 precisely, then funding verified removal or reduction projects that cancel out that amount.
FLY uses the ICAO (International Civil Aviation Organization) fuel-burn methodology: real aircraft types, real routes from 25,600+ IATA data points, and cabin class multipliers for economy, premium economy, and business. The result is your personal CO2 figure, not an airline average.
Process
How to offset your flight
01
Enter your route
Type a flight number or origin-destination pair. FLY uses live FR24 data to identify your aircraft type.
02
See your CO2
Get your exact kg CO2 per cabin class, broken down per leg for multi-city trips.
03
Choose removal amount
Select 25%, 50%, 75%, or 100% of your calculated CO2 to remove. Priced at ~EUR 100/tonne.
04
Receive certificate
Get a personalised TC-2026 carbon removal certificate with your route, CO2 figure, and removal amount.
Why FLY
Better than airline offset programmes
🎯
Precise calculations
ICAO fuel-burn with real aircraft types, not generic per-km averages that can understate emissions by 40%.
🌱
Verified removal
Nature-based removal projects including XPRIZE finalists. Physical CO2 removal, not avoidance credits.
📜
Named certificate
Personalised PDF certificate with your route, date, CO2 figure, and removal amount. Share or keep for records.
🌍
Global coverage
141+ airlines across 6 continents. African, Asian, and Middle Eastern carriers included alongside European and US.
Get Started
Ready to offset your flight?
Takes 60 seconds. Enter your route, see your CO2, support verified removal.
Enter your route into FLY (origin, destination, cabin class), review your CO2 calculation, then choose how much to remove. Payment via Visa, Mastercard, or most major cards. You receive a certificate immediately after payment.
Approximately EUR 1-20 per person depending on route and cabin. A short-haul flight costs around EUR 1-3. Long-haul business class can reach EUR 15-25. FLY shows your exact cost before payment.
High-quality removal projects that physically extract CO2 from the atmosphere are worth it. FLY funds scientifically rigorous projects, not low-quality avoidance credits. The key is using precise emission figures rather than rough averages.
Traditional offsetting funds emissions reduction elsewhere (e.g. protecting a forest). Carbon removal physically extracts CO2 from the atmosphere via biochar, enhanced weathering, or reforestation with soil sequestration. FLY focuses on removal, which climate scientists consider higher quality.
Airlines participate in CORSIA, but this covers only a fraction of total emissions using lower-quality credits. Individual offsetting via FLY lets you use precise personal calculations and higher-quality removal projects.
