Go to good.is for the full graphic

Good.is has a neat visualization (you know how I love those) on the impact of different modes of travel. The chart metrics are a little confusing (passenger miles per gallon is tough to get my head around) but the impact is noted.

I was surprised by the efficiency of the motorcoach vs a sedan.  But if you pack those things with people, your footprint per person goes way down.

I was happy with the Amtrak efficiency.  I have only ridden the Amtrak once from Oakland to Santa Barbara and thoroughly enjoyed the experience.  However, I must say that there were not 300 people on the train.  On one leg, I was the only person in the entire car. These numbers reflect only the efficiency when the mode of transportation is maxed out with passengers.  Unfortunately, we are going to have to change the way we get around for this graphic to be true a larger percentage of the time.

One last note, carpooling with 4 people in an SUV is more efficient  (miles per gallon per passenger) than one person in a hybrid.  So if you own a hybrid, get a carpool group together to really take advantage of the savings!

Make sure to read the discussion on the article too.  Good stuff.
