Qualitative and strategic evaluation of scope 3 emissions in Japanese automotive supply chains in Thailand
Abstract:
The expansion of the automotive industry has significantly contributed to the increase in greenhouse gas emissions through cross-border supply chains. Consequently, the internationalization of manufacturing and distribution networks presents considerable challenges for carbon accounting, transparency, and mitigation under established frameworks such as the Greenhouse Gas (GHG) Protocol. As a globally recognized standard, the GHG Protocol plays an essential role in measuring, reporting, and managing greenhouse gas emissions from organizations. In the JapanThailand automotive sector, manufacturers are increasingly required to account for emissions across their global operations, including indirect emissions. Building upon this context, this research examines the impact of Scope 3 emissionswhich originate from activities beyond a companys direct operationson Japanese automotive supply chains operating in Thailand, using the GHG Protocol as the foundational framework for analysis. The results underscore the importance of embedding Scope 3 emissions into supply chain governance to maintain competitiveness, comply with global sustainability benchmarks, and support Thailands long-term carbon neutrality targets. Policy proposals include establishing a national Scope 3 registry and reporting toolkit for SMEs, embedding Scope 3 metrics in Thailands BCG incentives, and developing OEM-led traceability platforms co-financed by public-private partnerships.
