EUROCONTROL boosts capability to assess environmental flight footprint / Factoring environmental performance early into air traffic management (ATM) concept evaluation is a must on the way towards more efficient and sustainable trajectories. EUROCONTROL has developed an Application Programming Interface (API) for its Research Network Strategic Tool which is now able to estimate 25 different emissions from the fuel burn of flights. The API delivers a more detailed overview on the environmental footprint of new concepts of operations helping to assess sustainability gains through improved performance.
