bulletin on the draft Climate Change Act. The Office of the Council of State is now working through <strong>Chapter 11, on carbon credits<\/strong>. Since late August, the same review has finished the chapter on an emissions trading system, opened the chapter on a Thai border carbon adjustment, and spent two weeks on a <strong>carbon tax<\/strong>, with the Excise and Customs Departments named as the collectors.<\/p>\n\n<p>The headlines will focus on the carbon tax. For sustainability, finance and IR teams at Thai companies, the more useful news is less dramatic. Every pricing chapter now under review draws on one input: the company-level greenhouse gas report in Chapter 6. And the government still has not said who has to file it.<\/p>\n\n<!--OBG-G--><div class=\"obg obg-toc\"><div class=\"obg-lb\">What this guide covers<\/div><ol><li><a href=\"#where-the-bill-actually-is\">Where the bill actually is<\/a><\/li><li><a href=\"#six-weeks-four-chapters-what-the-council-of-state-has-review\">Six weeks, four chapters: what the Council of State has reviewed<\/a><\/li><li><a href=\"#the-question-nobody-can-answer-yet-who-must-report\">The question nobody can answer yet: who must report<\/a><\/li><li><a href=\"#three-reporting-regimes-one-set-of-numbers\">Three reporting regimes, one set of numbers<\/a><\/li><li><a href=\"#where-english-comes-in-and-where-it-does-not\">Where English comes in, and where it does not<\/a><\/li><li><a href=\"#where-the-evidence-runs-out\">Where the evidence runs out<\/a><\/li><li><a href=\"#what-to-do-before-the-thresholds-land\">What to do before the thresholds land<\/a><\/li><\/ol><\/div><!--\/OBG-G-->\n\n<!--OBG-G--><div class=\"obg obg-stats\"><div class=\"obg-stat\"><div class=\"obg-sn\">14<\/div><div class=\"obg-sl\">chapters in the draft Act, 205 sections<\/div><\/div><div class=\"obg-stat\"><div class=\"obg-sn\">23<\/div><div class=\"obg-sl\">weeks of Council of State review, to 16 Oct 2026<\/div><\/div><div class=\"obg-stat\"><div class=\"obg-sn\">2027<\/div><div class=\"obg-sl\">DCCE\u2019s planned enforcement year \u2014 a target, not law<\/div><\/div><div class=\"obg-stat\"><div class=\"obg-sn\">1,211<\/div><div class=\"obg-sl\">companies holding a valid TGO CFO today<\/div><\/div><\/div><!--\/OBG-G-->\n\n<h2 id=\"where-the-bill-actually-is\">Where the bill actually is<\/h2>\n<p>The facts are short and come from DCCE itself. Cabinet approved the bill <strong>in principle on 2 December 2025<\/strong>. DCCE described it then as <strong>14 chapters and 205 sections<\/strong> plus transitional provisions, covering an ETS, a border carbon adjustment, a carbon tax, carbon credits and a climate fund. It went to the Office of the Council of State for legal drafting review. DCCE\u2019s own timeline, published on <strong>11 October 2026<\/strong>, says that in 2026 the bill is under that review <em>\u201cbefore going to the Cabinet and the legislative process\u201d<\/em>. So a second Cabinet decision and the whole of Parliament are still ahead.<\/p>\n<p>On 15 October, DCCE described the bill as one it <em>\u201cplans to enforce in 2027\u201d<\/em>, in a release about roughly <strong>81.6 million baht<\/strong> in World Bank grants signed on 14 October. Around 68 million baht of that goes to the Partnership for Market Implementation, which studies the design of carbon pricing instruments. A 2027 start would need the Council of State, Cabinet and Parliament to finish within about fourteen months. That is possible. It is not yet scheduled.<\/p>\n\n<h2 id=\"six-weeks-four-chapters-what-the-council-of-state-has-review\">Six weeks, four chapters: what the Council of State has reviewed<\/h2>\n<p>DCCE has posted a bulletin for most review weeks since the series resumed on 28 August.

First, the ETS chapter repeatedly refers to <strong>\u0e19\u0e34\u0e15\u0e34\u0e1a\u0e38\u0e04\u0e04\u0e25\u0e04\u0e27\u0e1a\u0e04\u0e38\u0e21<\/strong>, \u201ccontrolled legal entities\u201d, and gives officials power to inspect their emissions. The ETS is designed around a defined list of companies, not the whole economy. Second, the capital-market regulators were in the room for the trading sections, so allowances are being treated as tradable instruments, not just compliance paperwork.<\/p>\n\n<!--OBG-G--><div class=\"obg obg-quote\"><p>The bill\u2026 is planned to be enforced in 2027, and will be an important tool for achieving Thailand\u2019s long-term Net Zero 2050 goal.<\/p><cite>Department of Climate Change and Environment, release of 15 October 2026 \u00b7 our translation from the Thai<\/cite><\/div><!--\/OBG-G-->\n\n<h2 id=\"the-question-nobody-can-answer-yet-who-must-report\">The question nobody can answer yet: who must report<\/h2>\n<p>The reporting system already exists.

On <strong>7 October 2026<\/strong> DCCE ran its first training on the system for legal entities, with 100 participants including companies, verification bodies and TGO. The training covered user registration, reporting, verification and certification of reports under <strong>Chapter 6, Part 2<\/strong>. DCCE says the data will feed an ETS <em>\u201cor other carbon pricing mechanisms\u201d<\/em>.<\/p>\n<p>What the system cannot yet tell anyone is who has to use it. At the project steering committee on <strong>6 October<\/strong>, members asked DCCE to <em>\u201cclearly define which legal entities must report, in Phase 1, Phase 2 or later phases, so that they can prepare\u201d<\/em>. That request is the clearest public sign that the covered list has not been set. On 19 October DCCE announced the winning bidder for a consultancy to prepare for implementation of the bill and to draft its <strong>secondary legislation<\/strong>. That is where thresholds, sectors and deadlines are most likely to appear, after the Act itself passes.<\/p>\n\n<!--OBG-G--><div class=\"obg obg-facts\"><div class=\"obg-fact\"><div class=\"obg-fh\">Known<\/div><p>Reporting sits in <b>Chapter 6, Part 2<\/b>, and that part of the review was completed in July.

The practical answer for a company is not to wait for the government to reconcile them. Build <strong>one inventory<\/strong>, with one boundary, one set of activity data and the current <a href=\"\/th\/tgo-cfo-certification\/\">TGO emission factors<\/a>, and produce each report from it. A company that already holds a verified TGO CFO has most of the evidence trail a Chapter 6 report will need. For how that same inventory feeds a rater, see <a href=\"\/th\/tgo-carbon-to-ftse-disclosure\/\">from TGO carbon numbers to FTSE disclosure<\/a>.<\/p>\n\n<h2 id=\"where-english-comes-in-and-where-it-does-not\">Where English comes in, and where it does not<\/h2>\n<p>A report filed into a Thai government system under a Thai statute will be in Thai. That is compliance, and it does not need an English edition. English matters for the readers outside that system.<\/p>\n<p>The bill\u2019s Chapter 9 is a <em>\u0e44\u0e17\u0e22<\/em> border adjustment, aimed at imports. It does not change what Thai exporters owe Europe. Under the EU\u2019s CBAM, Commission Implementing Regulation (EU) 2025\/2547, Article 10(4), <em>\u201cthe operator\u2019s emissions report shall be submitted in English.\u201d<\/em> If your installation exports CBAM goods, the numbers in your Thai filing and in your English CBAM report have to match line for line. See <a href=\"\/th\/cbam-thailand-exporters\/\">CBAM for Thai exporters<\/a>.<\/p>\n<p>The same applies to investors. FTSE Russell scores Thai listed companies from their public disclosure, without a questionnaire, and Thai is not among the research languages its ESG Scores FAQ names (v1.5, \u00a71.8). SET itself <em>recommends<\/em> that listed companies disclose in English, because FTSE Russell assesses primarily from English (SET Q&amp;A, question 16). It does not require it. Once a carbon tax or ETS exists, the cost exposure it creates becomes a climate risk that global analysts will read about in your English One Report. The English edition is the version they actually read, so it is worth making it exactly right. Our <a href=\"\/th\/tsrs-s1-s2-bilingual-disclosure\/\">bilingual TSRS disclosure<\/a> work starts from that point.<\/p>\n\n<h2 id=\"where-the-evidence-runs-out\">Where the evidence runs out<\/h2>\n<p>Three caveats keep this honest.<\/p>\n<p><strong>The bulletins are DCCE\u2019s own summaries.<\/strong> The Council of State does not publish its working drafts, and DCCE did not post a bulletin for every week. We know which topics were discussed, not the wording agreed. Any section numbers or rates quoted elsewhere for the carbon tax or ETS should be treated with suspicion until the bill text is published.<\/p>\n<p><strong>2027 is a plan.<\/strong> No Cabinet resolution on the final draft, no submission to Parliament and no Royal Gazette item exists as of 23 October 2026.

Many readers of this post may not be required to report under the Act for years. The case for preparing now rests on the SEC\u2019s FY2027 timetable for SET50 and on export customers, which are already fixed, not on the Act.<\/p>\n\n<h2 id=\"what-to-do-before-the-thresholds-land\">What to do before the thresholds land<\/h2>\n<!--OBG-G--><div class=\"obg obg-take\"><div class=\"obg-lb\">Key takeaways<\/div><ul><li>Treat the Act as <b>coming, but not dated<\/b>.
