Multi-sector reduction potential of embodied carbon emissions in China: a case study of Liaoning province

Abstract

This study indicates that energy-related industries, such as coal mining and dressing, metal melting and rolling, electric and heat power, as well as petroleum refining, are the central causes of carbon emissions. China has been the largest emitter of carbon dioxide worldwide since 2008, and its current energy structure is still coal-dominated, which further increases carbon emissions. The reduction in these carbon emissions is a focus of attention in China, and the carbon reduction potential is particularly studied with the aim to issue appropriate mitigation policies. This study calculates the total embodied carbon emissions from a multi-sector perspective, using the economic input–output life cycle assessment model and analyzing the carbon reduction potential of Liaoning province, China. The level of export and provincial outflow consumption is the primary cause that leads to embodied carbon emissions from the consumption demand perspective. The carbon reduction potential is divided into three grades (weak, medium, and strong). Energy-intensive industries were classified as high carbon emission industries with the strongest potential for carbon emission reduction. This study provides policy insights that will aid the preparation of emissions reduction strategies.
