Thailand's Department of Climate Change and Environment (DCCE) opened a public consultation on July 20, 2026 on the second revision of the country's Long-Term Low Greenhouse Gas Emission Development Strategy (LT-LEDS), the national pathway to net zero emissions by 2050. Comments are due by July 27, 2026, giving climate and ESG teams a seven-day window to shape the assumptions that will underpin Thai decarbonization policy for decades.
The consultation invites every sector to weigh in on updated emission reduction milestones, sectoral pathways and the role of carbon-market instruments in the LT-LEDS, which Thailand submits to the UNFCCC under the Paris Agreement. Unlike the draft Climate Change Act, the LT-LEDS is a strategy document, not a binding obligation, but it sets the trajectory that later binding rules will operationalize.
What is the LT-LEDS, and how does it differ from the Climate Change Act?
The LT-LEDS is Thailand's long-term, economy-wide blueprint for low-emission development, submitted to the UNFCCC to articulate how the country reaches net zero by 2050. The second revision updates the pathway assumptions, sectoral mitigation ambition and the role of Article 6 carbon-market cooperation that the first version set out.
It is distinct from the Climate Change Act, which the Cabinet approved in principle on December 2, 2025 and which is expected to reach Parliament around 2027. That Act will create binding instruments: a national cap-and-trade ETS, a Thailand CBAM, a domestic carbon tax, mandatory GHG reporting and statutory carbon-credit assets registered with TGO. The LT-LEDS is the strategic compass; the Act is the enforceable machinery. Commenting on the LT-LEDS now lets industry shape the direction before the binding instruments lock it in.
| Aspect | LT-LEDS (under revision) | Climate Change Act (draft) |
|---|---|---|
| Instrument type | Strategy document submitted to UNFCCC | Primary legislation (Act) |
| Binding force | Non-binding pathway | Binding once in force, around 2027 |
| Lead authority | DCCE | DCCE; TGO for registry and MRV |
| Key content | Net zero 2050 trajectory, sectoral pathways | ETS, carbon tax, CBAM, mandatory GHG reporting |
| Current status | Public consultation until July 27, 2026 | Cabinet-approved in principle, awaiting Parliament |
Who should comment, and why does the window close on July 27?
Climate policy, ESG and transition leads at Thai energy majors, heavy industrials and SET-listed issuers should comment, because the revised pathway assumptions will flow into the targets they are already disclosing. SET50 issuers are now in their first mandatory ISSB climate disclosure year (FY2026 data) under the SEC's climate-first roadmap, and the LT-LEDS trajectory feeds the reference scenarios behind those disclosures and any science-based targets.
The seven-day window (July 20 to July 27, 2026) is unusually short for a national strategy revision, and DCCE has been running focus-group sessions to feed the draft since January 2026. Companies that want their pathway assumptions reflected, whether on residual emission levels, sectoral decarbonization depth or the use of international carbon credits under Article 6, need to submit within that window rather than wait for the legislative track.
How do you submit feedback to DCCE?
DCCE is collecting comments through three channels:
- Google Forms: the official consultation form linked from the DCCE announcement page.
- QR code: scanning the code on the DCCE page opens the same form.
- Email: [email protected].
DCCE states that every comment will be used to make the revised LT-LEDS more complete, appropriate and aligned with Thailand's development context. Submit on the record through one of these channels, not via informal contacts, so the input is attributable when the final strategy is published. The official source is the DCCE announcement page, and the submission form is the DCCE LT-LEDS consultation Google Form.
What should compliance teams do now?
First, verify whether your operations or portfolio companies are in the sectors the LT-LEDS covers and whether your current transition plan assumptions align with the revised pathway. Second, draft a focused comment on the two or three assumptions that most affect your decarbonization cost curve: sectoral ambition, residual emission levels and Article 6 credit use. Third, brief your government affairs and SET disclosure teams so the LT-LEDS comment and your FY2026 ISSB disclosure tell a consistent story. Fourth, track the Climate Change Act separately, because the binding ETS, carbon tax and CBAM obligations will follow the trajectory this consultation sets.
Continuous, per-jurisdiction real-time monitoring surfaces this kind of consultation the moment it publishes, so the seven-day window never catches a team off guard.
Take advantage of this real-time watch
Thailand's LT-LEDS revision is non-binding, but it is the document that the binding Climate Change Act will later operationalize. Climate and ESG teams have until July 27, 2026 to shape its assumptions, and Obsidian will keep tracking the consultation outcome and the Act's parliamentary progress as the binding layer takes shape.
