Emissions Calculation by atmosfair

The company atmosfair uses the external pageVDR standard methodologycall_made to calculate greenhouse gas emissions from business travel. Taking into account several important factors and based on the current state of climate science, atmosfair's emissions calculator records the flight emissions as accurately as possible. Factors such as flight altitude, aircraft type or number of seats on board play an essential role, as do holding patterns, detours and taxiing on the ground. However, the calculation can never be completely accurate, as only the probable emission of a flight can be considered. Factors such as the actual occupancy of the flight or rerouting due to weather phenomena are not included in the calculation.

Furthermore, the exhaust gases produced and emitted during a flight consist of more pollutants than just carbon dioxide (CO₂), which have additional, cumulative effects on the climate. Apart from the warming effect of CO₂, there are so-called non-CO₂ effects, such as contrails or the effect of nitrogen oxides (NO_x) on local ozone concentrations (Fig. 1). Other constituents such as water vapor, soot, or sulfate compounds also have warming or partially cooling effects on the atmosphere, but largely cancel each other out.
