It is important for realizing the coordinated development of digitalization and low-carbon and carbon neutral to understand the carbon implications of digitization of high-carbon manufacturing industry (HCM). Based on input-output and energy data, this paper analyzes the change of HCM carbon emissions in the process of digital transformation. Specifically, on the basis of estimating the carbon emissions (direct and embodied) of HCM, we not only compute the carbon emissions embodied in the digital process of various HCM subsectors but also reveal the formation and change mechanism by identifying their supply chain tiers and crucial transfer paths. The results show that: 1) Digital process of HCM can reduce carbon emissions. 2) The carbon emissions embodied in the digital process of HCM are increasing, and shifting from low-supply chain tiers to high-supply chain tiers. 3) The embodied emissions, supply chain tiers and crucial paths in the digital process of HCM show spatial heterogeneity. We suggest that the attention should be paid to increasing embodied emissions in the high-supply chain tiers and regional differences during accelerating HCM digitization, then implement appropriate digital carbon neutral policies
