A round-trip economy flight to Bangkok produces roughly 2,250 kg of CO2 per person — this is an illustrative estimate based on typical published aviation emission factors, not a precise measurement for your specific flight.
Yes — a round-trip business class flight to Bangkok produces roughly 6,750 kg of CO2 per person, about three times the economy figure, since your seat takes up more of the aircraft's total space and fuel burn.
No — it's an illustrative estimate using average distance bands and published emission-factor methodology, not calculated from your specific flight number, aircraft type, or load factor. Airlines and dedicated carbon calculators can offer more precise per-flight figures.
Fly economy rather than premium/business when possible, choose nonstop flights over connections, pack lighter, and consider a reputable verified carbon offset program for emissions you can't avoid.
