Take the Global Footprint quiz


The Global Footprint quiz is a fun and eye-opening exercise that roughly estimates how many planet Earths would need to exist to support everyone if they all lived like you do.

Your results break down how many global acres are needed to sustain your lifestyle and sorts your ecological footprint into a pretty, if disturbing, pie chart.

Take the quiz and then use the site’s tool to explore scenarios for reducing your footprint.
