This calculation uses version of Brighter Planet's flight carbon model. The flight greenhouse gas emission is the anthropogenic greenhouse gas emissions attributed to a single passenger on this flight. It includes CO2 emissions from combustion of non-biogenic fuel and extra forcing effects of high-altitude fuel combustion.
Calculations are performed adaptively, so methodology will vary depending on flight characteristics. Impact values, listed below, are based on a number of input factors, which in turn are based on others, and so forth. In each case, the methodology used in the calculation is specified, and, wherever possible, the source code of the method is displayed.
Conclusion: 0.0 kg
Method: from fuel use and greenhouse gas emission factor.
if cohort = cohort and cohort.respond_to?(:cleanup) then cohort.cleanup end (fuel_use * ghg_emission_factor)
Conclusion: 5.15214
Method: from fuel and aviation multiplier.
(fuel.co2_emission_factor * aviation_multiplier)
Conclusion: 2.0
Method: default.
2.0
Conclusion: 0.0 MJ
Method: from fuel use and fuel.
(fuel_use * fuel.energy_content)
Conclusion: 0
Method: from fuel per segment, segments per trip, trips, freight share, passengers, seat class multiplier, fuel, date, and timeframe.
date = if date.is_a?(Date) then date else Date.parse(date.to_s) end if timeframe.include?(date) then ((((((fuel_per_segment * segments_per_trip) * trips) * (1 - freight_share)) / passengers) * seat_class_multiplier) / fuel.density) else 0 end
Conclusion: 8351.048820476992
Method: from adjusted distance per segment and fuel use coefficients.
((((fuel_use_coefficients.m3 * (adjusted_distance_per_segment ** 3)) + (fuel_use_coefficients.m2 * (adjusted_distance_per_segment ** 2))) + (fuel_use_coefficients.m1 * adjusted_distance_per_segment)) + fuel_use_coefficients.b)
