Flight Carbon Removal

This product removes the total global warming impact of one passenger flying for one hour in economy.

115 kg of CO₂ is physically removed from the atmosphere and durably stored for 100+ years, with proof provided within one month of purchase.

Economy Class - Choose the total length of your flight in hours and add to cart.
Business Class - Multiply the amount by 3 to account for the lounge and larger cabin space.

The 115 kg is a comprehensive global figure that represents the full life-cycle and climate impact and includes direct fuel combustion, upstream production, and high-altitude atmospheric effects. 

Calculation data and methods:

1. Direct CO₂ Emissions: 84.4 g/pkm (TTW)
   This "Tank-to-Wake" (TTW) number represents the direct CO₂ emissions from the jet fuel burned during the flight. We use 84.4 g per passenger-kilometer (pkm), which is derived from the analysis of 27 million actual commercial flights, reflecting a real-world average across all aircraft types and global regions and accounts for actual passenger occupancy.

2. Non-CO₂ Multiplier: 1.7 (RFI / GWP100)
   The Radiative Forcing Index (RFI) is a multiplier used to calculate the Global Warming Potential (GWP) of non-CO₂ effects of flying, such as nitrogen oxides and water vapor, which create heat-trapping contrails at high altitudes. We use RFI 1.7 based on a 100-year time horizon (GWP100), which is a widely accepted baseline and commonly used in corporate ESG reporting and GHG Protocol compliance.

3. Upstream CO₂ Emissions: 20.3% (WTT)
   The "Well-to-Tank" (WTT) ratio accounts for the carbon footprint of the jet fuel before it reaches the aircraft, including crude oil extraction, refining, and global transport to airports. We apply a 20.3% uplift to ensure we account for the full life-cycle of the fuel, not just the portion burned in the air. This is derived by calculating the percentage difference between the ICAO Global Baseline for a full life-cycle (89.1 g CO₂e/MJ) and the standard direct combustion value (74.1 g CO₂e/MJ).

4. Average Flight Duration: 2h 15min
   The current global average duration for a commercial passenger flight segment. We use 2.25-hour average to calibrate our efficiency data. This allows us to offer a standardized "1 Hour" unit that is accurate for the majority of global travelers.

5. Flight Distance per Hour: 700 km
   The average distance a commercial aircraft covers in one "Block Hour" (gate-to-gate). We use 700 km to account for the total flight journey. It is calculated using the average distance per commercial passenger flight of 1,578 km, derived from the study (43.3bn kilometers flown divided by 27.45m flights), and then divided by the current global average flight duration of 2.25 hours. This results in an average block speed of approximately 700 km per hour.

6. Calculation:
   1. Direct CO₂: 700 km x 0.0844 kg = 59.08 kg
   2. Non-CO₂ (1.7x): 59.08 kg x 0.70 = 41.36 kg
   3. Upstream (20.3%): 59.08 kg x 0.203 = 11.99 kg
   --> Total: 112.43 kg, rounded up to 115 kg
