  • CO2-e or CO2-e: Carbon dioxide equivalency - Carbon dioxide is one of many greenhouse gases which are released into the atmosphere through natural and human activity. Each gas affects the natural cycle in a different way and to a different degree. To simplify this, a Carbon dioxide equivalency (CO2-e) has been calculated for all of the different greenhouse gases. CO2-e factors allow an easy and accurate way of assessing environmental impact from emissions.
