Thailand's Climate Change Act 2027: What Commercial Property Owners Must Prepare For

Thailand's Draft Climate Change Act was Cabinet-approved in December 2025 and is expected to take effect by 2027. For commercial property owners, facility managers, and real estate investors, the implications are significant — and the preparation window is short.

Key provisions of the Act

2030 emissions targets

20 to 25% reduction in greenhouse gas emissions below 2005 levels, with net-zero targets for 2050 and 2065.

Mandatory GHG reporting

Companies above specified thresholds must report greenhouse gas emissions to a national registry managed by the Thailand Greenhouse Gas Management Organisation (TGO).

National Emissions Trading Scheme (ETS)

A cap-and-trade system for large emitters. Companies that exceed their allocation must purchase credits; those below can sell.

Carbon tax framework

A carbon tax on emissions, with revenue directed to a national Climate Fund for green transition projects.

Thailand CBAM

A carbon border adjustment mechanism for imports, similar to the EU model, affecting trade-exposed industries.

Climate Fund

Financed by carbon tax and ETS revenue. Will fund green infrastructure, clean technology, and climate adaptation projects.

What this means for commercial real estate

Commercial buildings are significant energy consumers and GHG emitters. Under the Climate Change Act, large building owners and operators may face mandatory GHG reporting obligations — and potentially ETS participation if emissions exceed thresholds.

GHG reporting requirements will likely extend to building operations, including energy consumption, refrigerants, and maintenance activities

ESG-compliant buildings will be better positioned to attract international capital as investor ESG requirements tighten

Green building certifications (TREES-NC, LEED) will become more valuable as regulatory pressure increases

Verifiable external asset data — including cleaning compliance and building condition — will be required for complete GHG reporting

Early adopters of ESG data collection will have a significant advantage when reporting becomes mandatory

The external data problem

Most commercial buildings have reasonable internal data: energy bills, water consumption, waste records. What is typically missing is verifiable external data — the building envelope, facade condition, cleaning compliance, and the environmental impact of maintenance activities.

Under the Climate Change Act, this gap will become a compliance liability. Buildings that cannot demonstrate verified, auditable maintenance records will struggle to meet reporting requirements.

How autonomous drone operations address the gap

Every autonomous drone cleaning and inspection operation generates verified, auditable data:

96% CO₂ reduction compared to traditional cleaning methods — a measurable, verifiable emissions reduction

Chemical-free CleanWater approach eliminates chemical runoff and associated environmental impact

Battery-powered operations with minimal carbon footprint

Digital audit trails with timestamps, coverage data, and photographic evidence

ESG data independently verified for GRESB and regulatory submissions

What to do now

01Audit your current ESG data coverage and identify gaps in external asset reporting

02Establish baseline condition data for building facades and external surfaces

03Implement digital QA and reporting for all exterior maintenance activities

04Align maintenance contracts with ESG and Climate Change Act reporting requirements

05Consider GRESB participation to benchmark your portfolio against international standards
