Climate communications: the problem with buying cars based on miles-per-gallon
Nice illustration of how easy we can be fooled by numbers: to save gas, do you upgrade your 36 mpg car to a newer 46 mpg car, or do you upgrade your pickup truck from 15 mpg to 18 mpg? You drive both the same amount per year. Most people will select the 10 mpg fuel improvement – but they’ll save twice as much gas if they updated the pick up truck.
