openAVEM (Open Aviation Emissions)

openAVEM is a Python package that takes a list of flights as input and calculates fuel burn and atmospheric emissions: oxides of nitrogen (NOx),
hydrocarbons (HC), CO, non-volatile particulate matter (nvPM). Landing
and takeoff (LTO) is modeled with a time-in-mode approach, while the
non-LTO portions of flight (climb, cruise, descent) are modeled using
EUROCONTROL's BADA aircraft performance model (which needs to be acquired separately).
