SO₂ Emission Analysis of China with Input-Output Model

Abstract

Input-output modelling, which is characterised as a flexible analytical tool, is intensively used in life cycle assessment to estimate the environmental impact of production and consumption. In this paper, the extended Leontief input-output model is used to examine SO₂ emissions in China in 2007. Since direct and indirect SO₂ emissions from each sector can be quantitatively calculated by this model, the results would help uncover the relationships between the SO₂ emission transactions of different sectors. A series of indicators, including SO₂ emission multiplier, intersectoral total SO₂ emission intensity, and total SO₂ emission discharge percentage, are also determined to obtain a full understanding of SO₂ emissions in China.
