Major, yes, top 20? LOL. Each passebger jet flight you take likely puts out more pollution than you will do in your car in years, as will a campfire. The hippies are a bit backward these days.

Thabks for the impulse downvotes. If my figures are wrong, say so. But even with 400 passengers, the pollution per person per mile is way higher. You butthurt math challenged hippies can keep on downboting. You are only hurting your own cause.

  Your figures are so absurdly wrong that they could only come from willfully ignorance or intent to deceive. Coarse insults would be less offensive than your input. We're talking about carbon emissions, and the science is clear on that and yet we still have a constant volcano of misinformation from contributions like yours.

It's not fair to compare a 747 (which produces a lot of pollution) with a family car when the 747 carries 300+ people and travels far more miles. If you look at pollution-per-passenger-mile then jet transport is now more efficient and less polluting than light cars: http://www.slate.com/articles/business/the_juice/2014/07/driving_vs_flying_which_is_more_harmful_to_the_environment.html http://www.slate.com/articles/business/the_juice/2014/07/dri... and https://www.yaleclimateconnections.org/2015/09/evolving-climate-math-of-flying-vs-driving/ https://www.yaleclimateconnections.org/2015/09/evolving-clim...

  This is definitely true, but it's also a little disingenuous to compare in pollution-per-passenger-mile because commercial flight makes traveling further so much easier. With the ability to travel from JFK to LAX in 6 hours, significantly more people are traveling far distances that they wouldn't have bothered to travel if the only option was train/cars. Speaking as someone who likes to fly to remote places, planes may be more efficient per mile, but people travel significantly further in them and likely end up contributing quite a bit more to global warming than people who don't fly and just drive to a lake a few hours away instead.

  Don't forget that planes release their pollution higher up in the atmosphere which intensifies the global warming effect.
