A disaggregated emissions inventory for Taiwan with uses in hybrid input-output life cycle analysis (IO-LCA)

摘要

This paper reports on a life-cycle analysis (LCA) of Taiwan’s “agriculture and forestry”, “crude petroleum, coal and natural gas extraction” and “electricity generation” sectors, revealing for the first time Taiwan’s CO_2 and CH_4 emissions inventories and matching Taiwan’s input-output sectors. Integrated hybrid input-output life cycle analysis is used to disaggregate the electricity generation sector into nuclear, hydro, gas, oil and coal, and cogeneration. Results show that the fossil-fuel-related electricity sub-sectors have higher CO_2 emissions intensity than the remaining sectors in the economy and that the “paddy rice” sector is Taiwan’s most CH4-intensive sector, making rice cultivation an important source of CH_4 emissions. This work is vital to sound policy decisions concerning power generation, coal, and agriculture and forestry at the national level.
