and it's somewhat less alarming than this diary makes it out to be:

This sounds like a tremendously poor miles-per-gallon rating! But consider that a 747 can carry as many as 568 people. Let's call it 500 people to take into account the fact that not all seats on most flights are occupied. A 747 is transporting 500 people 1 mile using 5 gallons of fuel. That means the plane is burning 0.01 gallons per person per mile. In other words, the plane is getting 100 miles per gallon per person! The typical car gets about 25 miles per gallon, so the 747 is much better than a car carrying one person, and compares favorably even if there are four people in the car. Not bad when you consider that the 747 is flying at 550 miles per hour (900 km/h)!

any sort of commercial aircraft is an ecologic disaster.

What's worse, commercial flights within the US get half the milage of intercontinental 747s.

How big is your personal carbon footprint?

• ##### What matters though(7+ / 0-)

Is the total

Yes, flying might burn less than driving that trip would, but both are more than the trip not taken.

It also seems like an easy place to start.  I wonder for example what proportion are business travelers and how much money (which talks) and thereby carbon might be saved by convincing companies that teleconference are the way to go.

Clearly a part is prioritizing which trips are important and which aren't.  Of course cap and trade,  a carbon tax, and production limits all force up prices reducing use until its carbon efficient

• ##### Flying is such luxury tho'(0+ / 0-)

No one is going to be unable to fly to the grocery store, or take the flight to the dentist. The burden is on people who can pay.
