Other indicators
Carbon Dioxide is not your only environmental impact. There are other non-carbon impacts that result from your lifestyle and have an effect on the environment. Your CO2 emissions are an indicator of your contribution to climate change, but climate change isn't the only global environmental problem we face.
The Eco Footprint
The Eco Footprint measures various aspects of your lifestyle (including CO2 emissions) and expresses your impact in terms of the amount of land required to absorb the impact of your lifestyle.
