Research Objectives:To measure and analyze consumption-based carbon emission from the perspective of international final demand.Research Methods:Based on World Input-Output Database(WIOD),this paper uses MRIO model to measure consumption carbon emission of main countries (regions) in the world.Research Findings:The results show that China is the biggest country in carbon emission embodied in exports and EU transfers the most carbon emission. Developed countries have a higher proportion of consumption-based carbon emission from overseas,which mainly comes from developing countries.Carbon emission embodied in export of developed countries mainly comes from service industry,while that of developing countries is from mining and quarrying,heavy industry and electricity,gas and water supply. As to realization path,carbon emission embodied in trade of China and India which are characterized by export processing trade is mainly caused by export of final product,yet countries such as Russia and Australia which are the main exporter of energy and mineral resources realize their emission embodied in trade mainly by the export of intermediate product. Research Innovations:From the angle of consumer responsibility principle,this paper measures consumption-based carbon emission of different countries (regions) based on productionbased carbon emission,and analyzes the industry structure and realization method of embodied carbon in trade.Research Value:This paper contributes to providing a new idea for accurately measuring carbon emission and defining corresponding carbon emission reduction responsibility in international climate change negotiations.
