Characteristics of Multi-national Carbon Emissions Based on Empirical Mode Decomposition

摘要

According to the complexity of the reasons of carbon emissions in different countries, empirical mode decomposition method are used in this paper, decomposing the time-series data of national carbon emissions into high frequency modal and trends modal, represent the national carbon emissions short term interference and long term trend respectively. At the same time, the characteristics of each countries' carbon emissions are analyzed, the result show that the England carbon emissions in the downward phase and it's mainly affected by short term factors, however, the United States, Japan, Australia, Canada and China whose carbon emissions are still on the rise phase and they are affected by the long term trend.
