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

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 CH 4 ‐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.
