Long-haul flights produce about 0.2 tons of CO2 per passenger per 1000 km, yet many travelers won't even consider a train for shorter trips because it takes an extra hour. I've cut my own flying significantly, but I still book a plane when visiting family across the border—the schedule simply doesn't align. Should we really be shaming individuals for their flight choices when the infrastructure for low-carbon alternatives remains so patchy? Personal responsibility feels real, but without better rail and pricing, the guilt lands unevenly.
