Burn calories not electricity

I wrote a post about elevators some time ago and today I got a picture from a friend:
This sign was given by the NYC (free-of-charge) to any building that wanted to mount it. From this campaign:
Benefits of Taking the Stairs:
 - Stair climbing burns almost 700% the number of calories you burn standing on an elevator.
 - Just two minutes of stair-climbing each day burns enough calories to eliminate the one pound an average adult gains each year.
 - Men who climbed at least 20 floors a week (about 3 floors a day) had a 20% lower risk of stroke or death from all causes, in one study.
 - Stair-climbing has been shown to raise good cholesterol and improve cardiovascular health
Stair use also advances the city’s GreeNYC effort to reduce energy consumption. An escalator that operates 24 hours a day, seven days a week, can use 28,000 kilowatt hours of energy over the course of a year. That’s enough to create 43,000 pounds of carbon dioxide – more than three times the amount a car produces.

Posting such signs has been shown to increase stair use by approximately 50 percent.
