Abstract

Methanol, as a renewable and clean energy carrier, has an important position and broad prospects in realising a low-carbon future. Based on the idea of hierarchical attribution management (HAM), this study evaluates the life cycle carbon footprint (CF) of methanol production, focusing on coal-to-methanol (CTM) and biomass-to-methanol (BTM) processes. The results showed that the CF was 0.2759 kgCO₂-eq/MJ CH₃OH for CTM and 0.1833 kgCO₂-eq/MJ CH₃OH for BTM. The CF from BTM are 66.44 % of those from CTM. The methanol production process was the major contributor of CF for both processes, accounting for 96.93 % and 70.53 % of the total CF, respectively. This study was extended to project the carbon emissions from methanol production in 30 provinces in China from 2021 to 2035, considering different power structures. Sensitivity analyses of 24 scenarios further examined the impact of key inputs on total carbon emissions. This study highlights the importance of biomass utilization for carbon reduction and provides insights for strategic environmental investment planning.

期刊介绍： The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
