NYC carbon footprint: 54,349,650 tons a year = 148,903 tons a day = 6,204 tons an hour = 1.72 tons a second

In 2010 New York City added 54 million metric tons of carbon dioxide (equivalent) to the atmosphere, but that number means little to most people because few of us have a sense of scale for atmospheric pollution.

Carbon Visuals and Environmental Defense Fund make carbon emissions feel a bit more real - the total emissions and the rate of emission. Designed to engage the 'person on the street', this version is exploratory and still work in progress.
