1) Flight operations in LTO cycle (up to 915 metres), taking into account actual engine power, APU, engine start-up and airframe

2) Retroactive adjustment to the calculation method.

3) In accordance with the GHG Protocol: Flughafen Zürich AG’s own sources (vehicles, machinery, heating)

4) In accordance with the GHG Protocol: Electricity sourced by Flughafen Zürich AG externally

5) In accordance with the GHG Protocol: Aircraft in LTO cycle and complete route (outbound flight only), calculated by Eurocontrol, other emissions sources at the airport (handling, other heating) and all landside traffic in the vicinity of the airport (approx. 3 kilometres) for all modes of transport
