Students from around the world calculated their class mean and standard deviations for their footprints and posted them on our world map.
Do you see differences across the globe? If so, why do you think those differences exist?
Did you use the calculator to try to reduce your footprint down to the average from a citizen of another country? What changes would you have to make to lower your footprint in this way? Are you going to try and take some of these actions in your daily life?

The Effects of Light Usage
When I calculated my carbon footprint I found that my light consumption was what caused one of the biggest spikes in my carbon footprint. I live in a big house of which uses up a lot of light to keep it lit. On average, incandescent light bulbs create 4,500 lbs. of CO2 each year. After finding this out i have adapted to turning off any lights that aren't in use. The simple act of turning of lights is incredibly helpful as it is proven that .43 kgs. of carbon dioxide per kilowatt hour of electricity is consumed. So turning off unnecessary lights conserve both the energy bill and the amount of CO2 released.
