This brief explores how climate finance in Thailand can be scaled up to meet the country’s net-zero targets.
Thailand has pledged to reduce greenhouse gas emissions by 33% unconditionally—and up to 40% with international support—by 2030. It seeks to achieve carbon neutrality by 2050 and net-zero emissions by 2065.
While Thailand’s climate finance landscape has made meaningful progress over the past 6 years, with mitigation-related investments totaling 1.6 trillion baht ($47 billion) from 2018 to 2024, adaptation accounted for less than 1% of climate finance, which remains concentrated, fragmented, and insufficient to meet the country’s targets.
Meeting these targets will require a substantial scale-up in finance. From 2018 to 2024, average annual nationally determined contribution (NDC)-related investment stood at $8 billion. From 2030 onward, the country will need to mobilize at least $21 billion yearly to stay on track.
This brief explores how climate finance in Thailand can be scaled up to meet the country’s net-zero targets. It explores financing gaps, current flows, and key reforms to unlock investments in underfunded sectors.
