Financing NDC 3.0: Challenges and Opportunities Toward Net Zero 2050 

Thailand’s updated NDC 3.0, submitted to the UNFCCC ahead of COP30 in November 2025, marks a major step forward in the country’s climate ambition. By shifting from BAU-based projections to absolute emission-reduction targets, Thailand has pledged to cut net GHG emissions by 47%—or 135.2 MtCO₂eq—from 2019 levels by 2035

Yet behind this ambition lie critical financing challenges. NDC 3.0 estimates that Thailand will need an additional USD 7.05 billion in investments by 2035, with nearly 86% directed toward the energy and transport sectors. At the same time, limited transparency on sectoral investment plans, insufficient attention to adaptation and loss and damage, and constrained access to international climate finance raise concerns over the feasibility of the transition.

CFNT Briefing examines the financing gaps between Thailand’s NDC 3.0 commitments and actual investment flows, drawing on insights from Thailand Climate Finance Tracker. It highlights sectoral mismatches in priority technologies and explores opportunities for policymakers, financial institutions, and international partners to mobilize finance, leverage global climate mechanisms, and accelerate Thailand’s journey toward net zero.
