		reportingsjr on June 17, 2013 \| parent \| context \| favorite \| on: We're Too Cheap to Fly Faster I just want to point out that those car CO2 figures don't go to very high fuel efficiency rates. I have a prius c (high on the efficiency scale, I know) and I just calculated about 290 grams of CO2 per mile (about 50mpg). Still not amazing, but a good bit better than 390g CO2/mile. That's just for one passenger as well.

Good point. Of course, modern 787s and A380s are also far more fuel efficient then then '60s and 70s era aircraft. According to Wikipedia, the 787 is 20% more efficient then a 767
