Abstract:
This study examined the greenhouse gas (GHG)
emission characteristics of surface treatment,
lightweight metal processing, and mold manufacturing
industries in Taiwan's metal and electrical machinery
manufacturing sectors. Carbon inventory analysis of
22 enterprises revealed that Scope 2 (indirect)
emissions accounted for an average of 67.99% of total
emissions, while CO2, CH4, and HFCs were the main
Scope 1 (direct) emissions. Fugitive emissions
dominated the lightweight metal processing industry,
fixed emissions prevailed in surface treatment, and
mold manufacturing had a balanced profile. Notably,
per capita carbon emissions in the mold manufacturing
industry were 11.07 tonnes CO2e/person, 4 times
higher than in the other two industries, suggesting that
Scope 1 and 2 emissions can serve as distinct
indicators of the level of process automation or smart
production implemented within these industries.
