The Analysis to the Influence of Carbon Dioxide Emissions in Different Countries

There are some indicators to measure the CO2 emissions now. But they ignored the effects of the external influences. In this paper, we established an indicator of carbon dioxide emission per square measure, and then analyzed the major emitting countries' CO2 emissions. On this basis, we had a comparative analysis to the countries' CO2 emissions by using the indicator of carbon dioxide emission per square measure and other assessment indicators of measuring CO2 emissions. We found that when we measure a country's CO2 emissions by different indicators, we got different results. So we concluded that it is unfair to measure the influences of one country's CO2 emissions by single indicator but by integrated indicators. And integrated indicators can objectively and fairly measure the impacts of CO2 emissions in different countries. (C) 2011 Published by Elsevier Ltd.
