Application of an Integrated Model to Manufacturing Sector’s Carbon Emission

Abstract

Based on a three-term plan, this study applied an integrated model (IPCC-RA-LMDI-TD) to analyse China's Carbon Emission from the manufacturing industries (CCEMI) for 2001-2020. Results revealed that for the long-term plan of CCEMI and decoupling analyses, the activity effect was the main enhancing factor while the intensity effect was the main limiting factor. For medium and short-term plans of CCEMI and decoupling analyses, the main enhancing factors are the activity effect followed by the carbon emission factor while the main inhibiting factors were structure effect, after intensity effect. In general, the sector's resultant decoupling status is mainly Expansive negative decoupling (2.22 in 2011-2015 and 1.27 in 2016-2020) followed by Expansive coupling (0.81 in 2001-2010). Nevertheless, the status is Expansive negative decoupling in the second half of the study period suggesting deterioration of the decoupling index of the sector over the study period. To actualize sustainable development, there is a need for environmentally friendly strategies such clean energy and technology deployment.
