Thailand Roadmap to Nationally Determined Contributions: Can Existing Energy Efficiency be the Potential Measure to Achieve Climate Industrial Sector Target in Thailand?

Abstract

Thailand adopted energy management system initiatives in 2010, mandating designated factories to report plant-based energy consumption and conservation data. Validating energy savings from various measures is essential for tracking GHG mitigation performance and predicting future energy trends. Aligning with the 2030 NDC Roadmap, this study proposes three types of energy efficiency measures in large-scale industries: (i) housekeeping, (ii) process improvement, and (iii) machine change equipment. The study also aims to evaluate cumulative savings and GHG mitigation. Our findings indicate that real-world energy efficiency measures resulted in a reduction of 6.27 Mt CO₂ by 2030 which reflect for only 38.00 % of industrial NDC target. However, achieving the target requires an annual average energy saving growth rate of 24.15 %, by using the additional energy in transition measures such as hydrogen and CCUS. Long-term, tailored strategies for specific industrial sectors are essential to pave the way for a sustainable industrial future for the country.
