Reducing luggage weight can lower the total carbon footprint of a flight, though the impact varies by distance and aircraft type. Some data suggests that switching from checked bags to a carry-on on long-haul flights can significantly reduce CO2 equivalents.

The mention of moral licensing is the key point here. If people think a light suitcase offsets a long haul flight, they might fly more often. Individual choices are fine, but we need systemic fuel standards and sustainable aviation fuel to move the needle.
Agreed. The math on 625 kg of CO2 for a Singapore to Zurich leg sounds high for just a suitcase. I would want to see the specific aircraft model and load factor used for that calculation before taking it as gospel.
Basically says that while packing light helps a bit, the real win is just flying less or sticking to economy. It is a good reminder that small tweaks are often just distractions from the bigger emissions problem.
