About these numbers.
01What share of Thai listed companies hold an ESG rating?+
About 28% — Othello’s dataset of 936 SET and mai companies (as of 12 Jul 2026) shows 260 with an ESG rating. The gap is widest on the mai board, where only 9% are rated versus 34% on the SET, so a SET company is roughly 3.8 times more likely to hold a rating than a mai company.
02How many Thai listed companies disclose greenhouse-gas data?+
Around 32% (297 of 936) disclose GHG figures, by Othello’s analysis as of 12 Jul 2026. Disclosure concentrates among already-rated companies: 68% of rated companies report GHG data, well above the market-wide rate. Agro & Food and Resources lead on GHG disclosure by sector; Property & Construction and Consumer Products trail.
03Are these statistics official?+
The company-level figures are Othello International’s own analysis of public SET and mai disclosure data as of 12 Jul 2026, not an official SET or SEC publication.

Behind every number is a disclosure gap.
Most of these gaps are not missing work — they are work that never made it into complete, English, framework-legible disclosure. That is exactly what we build.
