Long-term consumption-based accounting of CO2 (1948-2011) in global view

Accompanied the boom of global economy, soar the CO2 emissions during the past decades, with developing group showing higher growth rates than the developed. Geographical separation in production and consumption or the so-called carbon leakage is suggested to be one of the main reasons. Based on detailed input-output data, existing studies have derived consumption-based emission series in some 20 years together with combustion ones. In order to broaden data coverage, to which existed studies fail due to data availability, we develop a new model to embrace years from 1948 to 2011. The results basically coincide with existing studies. And it has displayed emission estimations in 3 levels: upper-bound level, lower-bound level and mean level. What is more, this model is succinct enough to be easily expanded for future estimations in GHGs or other ecological footprints analysis considering material flows. The emission transfers and consumption based emissions calculated are rocketing significantly, and a synthetic consideration of historical emissions in both views (producer and consumer respectively) is solemnly recommended in order to achieve solid progress in future climate policies, especially for future ADP scheme under which all parties are subjected.
