@galaxyproject almost everyone from the Freiburg Galaxy team going to #gcc2024 in Brno this June is going to travel there by train. Per person that saves ~ 200 kg of CO2.

Overall carbon footprint from traveling to GCC will, of course, be dominated by flights from outside the EU so how much potential is there for tweaking, e.g., the footprint of transatlantic flights?

Following are the results of the quick research I did this morning:

(to get the numbers I've been using https://co2.myclimate.org/en/flight_calculators/new, and expedia to get flight suggestions)

- roundtrip JFK - PRG using direct flights: 2.4t
- same roundtrip with a stop-over in Frankfurt: 2.6t
- roundtrip LAX - PRG with a stop-over in Amsterdam: 4.0t
- roundtrip LAX - PRG with a stop-over in Frankfurt: 4.1t
- roundtrip LAX - PRG with stop-overs in Las Vegas and Frankfurt: 4.3t

These are only estimates, not taking aircraft models into account, but bottom line is: non-European participants can save as much CO2, by just optimizing their flight route and minimizing stop-overs, as we can by avoiding intra-European flights.
