Every wednesday, One Block Off the Grid publishes an awesome infographic about energy.
I thought this infographic on traveling and the greenest way to get somewhere in terms of pounds of CO2 emitted per trip - car, bus, train, or airplane - was particularly informative.
I am however, a bit confused about the emissions associated with taking a plane. They seem very low -- to go across the country from NYC to Los Angeles, flying is less pollutant than taking a train?
I always thought flying was by far the least green way of getting somewhere. This article does a similar transport comparison with results which are pretty consistent with the infographic - except for the airplane emissions (the article says ~2,500 lbs CO2 from NYC to San Francisco). Any thoughts? Maybe I'll contact 1BOG about this.
