You’re multiplying the amount of CO2 dramatically. That is the amount of CO2 for the entire plane, not calculated per passenger. Emissions are always calculated per passenger for different methods of transportation, otherwise you’re multiplying the output by potentially hundreds.
Edit: I think I’m wrong. I’m getting different results saying those numbers are actually closer to the per passenger number. I’d have to do the math but it’s definitely more than a burger by a long shot, just from a logical calorie conversion.
I like the term “cultural voyeurism.”
