Published 2026-03-06.

Thailand is the largest automotive producer in Southeast Asia. Japanese and European OEMs increasingly ask Thai tier-1 and tier-2 suppliers for emission data for their Scope 3 inventories. Use the latest official Thailand grid emission factor for Scope 2. Emission sources: Scope 1 (paint shop, welding, heat treatment), Scope 2 (PEA/MEA electricity), Scope 3 (steel, aluminium, plastics). TGO Carbon Footprint for Product (CFP) certification is increasingly requested by OEMs. SEC-ESG requirements cascade to SME suppliers. Eastern Seaboard industrial estates house many auto parts SMEs. BOI provides tax incentives for eligible green manufacturing investments.
