AIR TRAVEL CARBON FOOTPRINT

International air travel significantly impacts our climate, contributing approximately 2.5% of global CO₂ emissions and around 3.5% of non-CO₂ emissions. Flights contribute to climate change not only through CO₂ emissions but also through radiative forcing: the global warming effect of non-CO2 pollutants such as water vapor and aerosols. Considering these non-CO₂ residuals is crucial as they significantly enhance the overall climate impact of flights.

FORLIANCE incorporates the comprehensive climate effects of air travel by applying an RFI (Radiative Forcing Index) multiplier when calculating flight emissions. This factor adjusts the emissions to account for both CO₂ and non-CO₂ effects, providing a more accurate depiction of the total climate impact.
To ensure accuracy, FORLIANCE follows the methodology established by the UK Department for Business, Energy and Industrial Strategy (BEIS), a reliable source for flight emissions factors. BEIS has developed a robust methodological framework, minimizing the risk of commercial interference and providing government-published data. Consequently, FORLIANCE applies an RFI multiplier of 1.9 to flight emission calculations.
While there is ongoing scientific debate regarding the precise value of this multiplier, and it is subject to significant uncertainty, using an RFI of 1.9 is currently considered a reasonable approach to account for the radiative forcing effects of air travel.

Understanding and accurately calculating the climate impact of air travel is essential for making informed decisions about carbon management and climate action. By using the RFI multiplier, FORLIANCE ensures that the full range of aviation’s environmental impacts is considered, leading to more effective carbon management strategies.

FORLIANCE is committed to helping organizations and individuals mitigate the climate impact of air travel. By providing accurate emissions calculations and promoting sustainable travel practices, we aim to reduce the carbon footprint of aviation and contribute to global climate goals.
