The very words "global warming" tend to make the problem seem insurmountable and even somewhat remote. Indeed, the state of California recently implemented the most stringent emissions standards in the country and many nations are now operating under the Kyoto Protocol (find out more). However, there is no doubt the each person contributes to the overall carbon load — with their own carbon footprint.The average American is responsible for about 20 tons of carbon dioxide emissions each year, a far greater per capita number than that of any other industrialized country. In fact, the US accounts for more than 20% of the world's total greenhouse gas emissions. You can reduce your carbon footprint by driving a more efficient car, or driving less. You can also plant trees or help preserve forests to offset your emissions, since trees are a sink for carbon.
How can you determine how much you're adding in greenhouse gasses? The Safe Climate Institute of the World Resources Institute has an easy carbon footprint calculator. All you need is how much your travel by car and air. Next, describe the energy you use at home. You can most easily find this data on your utility bills. And then the number of people in your household. The tool will then compare your carbon footprint with others of your nation!
