This is sad to hear! Early in my career I worked for a company making airport collaborative decision making (A-CDM) software. One of the most impactful projects to which I contributed was a model that calculated the exact right moment for a pilot to turn their engine on given likely pushback times etc. That saved quite a lot of fuel (and therefore cost and pollution) back in the day. It's a real shame if similar thinking isn't being applied to the problem you describe.
