The Climate Change Act: From Voluntary to Mandatory
Approved in principle by the Cabinet in December 2025, the Climate Change Act (or “Global Warming Act”) serves as Thailand’s first master law on climate governance. It shifts the nation from a voluntary, incentive-based approach to a binding, rules-based system.
- Mandatory Transparency: In “Phase One,” the law mandates greenhouse gas (GHG) emission reporting for (approximately 4,000) “controlled legal entities”— primarily large-scale industrial players. This creates a transparent baseline for national emissions.
- Carbon Pricing: The Act introduces a multi-pronged Carbon Pricing strategy:
- Carbon Tax: The Excise Department has already launched the first phase, targeting the oil and petroleum sectors.
- Thailand CBAM: Mirroring the European Union’s Carbon Border Adjustment Mechanism, this ensures that Thai exports meet international standards, protecting local businesses from “carbon leakage” and maintaining trade parity with the EU.
- Emissions Trading System (ETS): A “cap-and-trade” model where the government sets emission limits and allows companies to trade surplus permits.
- Carbon Credit Integration: To support local reduction and sequestration projects, the law allows companies to use Thai carbon credits (TVER) to offset up to 15% of their obligations within the ETS
- The Climate Fund: This fund will act as a financial engine to
- Enhance Resilience: Invest in infrastructure that protects against climate-related loss and damage.
- Support Innovation: Provide revolving capital for clean energy projects and sustainable agricultural practices.
- Safety Nets: Fund advanced early warning systems to mitigate the impact of natural disasters on the population.

Institutionalizing Carbon as a Financial Asset
On February 10, 2026, the Cabinet approved the expansion of the Futures Trading Act B.E. 2546 (2003). Under SEC supervision, this upgrades Thailand’s financial infrastructure by adding:
- Carbon Credits (now classified as deliverable “goods” rather than just variables).
- Greenhouse Gas Allowances and Renewable Energy Certificates (RECs).
By allowing these to be traded on the Thailand Futures Exchange (TFEX), the government provides businesses with sophisticated tools to hedge price risks and manage environmental costs effectively, aligning with the 2050 Net Zero goal.

Transforming the Grid: NDC 3.0 & Renewable Energy
To meet the NDC 3.0 target, a new committee is finalizing the Power Development Plan (PDP 2026). The plan ensures that renewable energy supply meets the high-capacity demands of data centers and MNCs through:
- Utility Green Tariffs (UGT): UGT1 (already launched) uses existing capacity, while UGT2 (planned launch for 2026) will feature new RE sources and bundled RECs.
- Third Party Access/ Direct PPAs: A pilot project for 2,000 Megawatts specifically targeting data centers, currently undergoing public hearings to allow third-party access through the national grid.
.
The “Quick Big Win” Solar Initiative
Launched on September 30, 2025, this fast-track scheme aims to reduce household costs and boost community income through four pillars:
- Agricultural Solar: Over 1,200 solar-powered water pump systems.
- Community Solar: Farms allowing over 300 communities to sell power to the state.
- Household Rooftop Solar: Personal income tax deductions of up to 200,000 Baht.
- Floating Solar: Large-scale hybrid hydro-solar projects by EGAT (1,600 MW capacity).
.
Urban & Industrial Decarbonization: The LCC Project
The Cabinet approved the “Low Carbon City (LCC) and Carbon Market Development” project on December 9, 2025, backed by an initial US$100 million loan from the World Bank.
- Industrial Estates (IEAT): Pilot sites at Map Ta Phut and Laem Chabang are being transformed into low-carbon hubs using solar arrays, large-scale battery storage, and industrial EV charging. This initiative is expected to cut 2.33 million tonnes of CO2 over ten years.
- Bangkok (BMA): The BMA is collaborating under this framework to reach Net Zero by 2030 for city operations. Key focuses include energy-efficient buildings, transitioning public transport to EV, and creating a local carbon credit market to fund urban greening.
The shift from the “high-growth, high-pollution” model to a low-carbon trajectory is not merely an environmental choice—it is a wholesale modernization of Thailand’s industrial identity.
Ultimately, this roadmap is designed to ensure that Thai businesses remain competitive and that the country becomes the preferred destination for the next wave of “green” foreign investment. For companies operating in Thailand, the message is clear: the transition is no longer a distant goal, but the new legal and financial baseline for doing business.
