Devising an integrated methodology for analyzing energy use and CO2 emissions from Taiwan's petrochemical industries.
Input-output modeling and multiplier analysis are used to assess Taiwan's five petrochemical industries, based upon their economic contribution and potential impacts on energy consumption and CO2 emission. In addition, a consolidated index system was developed for evaluating energy and economic efficiencies as well as targets for CO2 reduction. Results indicate that petrochemical materials (PM) make a major contribution to economic development, with lesser contributions from plastic materials (PL) and artificial fibres (AF). PM has the highest energy multiplier while PL has the largest induced potential for energy consumption. Plastic and rubber products (PP, RP) are relatively insignificant energy consumers. AF has the highest CO2 multiplier, and its induced potential for CO2 emission is the most significant. The consolidated index shows that the upstream petrochemical industries perform rather poorly in an integrated view of economic, energy, and CO2 emission, and should be seen as the primary targets for CO2 reduction. Investment of the petrochemical industries in Taiwan should be adjusted to improve energy efficiency, economic bases, and lower CO2 emissions.
