Othello Is Now an Official ISSB Training Partner for Thailand

On 29 October 2026, Othello ESG Consultant Company Limited signed a licence with the IFRS Foundation under the ISSB Training Partner Programme. We are now an official ISSB Training Partner, licensed to deliver the ISSB Disclosure Training in Thailand.

The ISSB Disclosure Training is the official curriculum on the IFRS Sustainability Disclosure Standards set by the International Sustainability Standards Board (ISSB), including IFRS S1 and IFRS S2. The content is developed and owned by the IFRS Foundation, the organisation behind the Standards themselves.

What the licence covers

The ISSB Training Partner Programme recognises organisations approved to deliver official training on applying the IFRS Sustainability Disclosure Standards. Training Partners teach from IFRS Foundation-developed materials and meet defined delivery standards, so a participant in Bangkok gets the same core curriculum as a participant anywhere else in the programme.

Our licence is jurisdictional, for Thailand. Only trainers who have completed the IFRS Foundation’s trainer assessment deliver the course. Alongside the official curriculum, we add a Thailand module covering the SEC’s rules and Form 56-1 One Report-S. That module is Othello’s own content and is labelled as such.

Othello ESG Consultant Company Limited is listed under Thailand in the IFRS Foundation’s official directory of ISSB Training Partners — the public record of organisations that have completed the programme’s onboarding.

What participants get

Full course details, upcoming dates and a Thai-language guide are on the ISSB Disclosure Training page.

Why this matters now

Thailand’s ISSB-based rules are no longer a consultation. The SEC’s nine notifications came into force on 26 October 2026, with a new Form 56-1 One Report-S and a preparation manual. We set out the detail in our analysis of the SEC rules. The phase-in runs by index group:

For the SET50 group, FY2027 is the first data year, and it starts in about two months. Which companies are in that group will be fixed by SET’s December 2026 review, which we covered in our note on the SET50 cohort. Greenhouse gas data needs external assurance from the first filing, with no transition relief. The finance, sustainability and investor-relations teams who will sign off these reports need to understand IFRS S1 and IFRS S2 before the data year begins, not after.

Where the course fits with the rest of the work

Training is one part of getting ready. The same teams also need a reliable greenhouse gas inventory and a disclosure that reads correctly in both Thai and English. The IFRS Foundation has not published an official Thai text of IFRS S1 or IFRS S2, which we explain in our note on the missing Thai text. Related services:

• Carbon footprint, Scope 1, 2 and 3 (CFO and CFP), the inventory that IFRS S2 metrics are built on.
• IFRS S1 and IFRS S2 bilingual disclosure, for the report itself.
• Our map of ISSB adoption in Thailand and ASEAN, for the regional picture.

First public cohort

Our first public cohort of the ISSB Disclosure Training is planned for December 2026 in Bangkok. In-house sessions for a single company’s board, finance or sustainability team can be arranged on request.
