Iron & steel in Thailand: emitters, CO2 & carbon value

11 tracked facilities, ≈2,137,439 t CO2/yr combined — here are the largest, what that CO2 is worth at current prices, and the sector's reduction pathway. Full sector pathway: decarbonizing iron & steel.

The numbers

Iron & steel in Thailand at a glance

Metric	Value	Note
Facilities tracked	11	with CO2 estimates
Total est. CO2	2,137,439 t/yr	Climate TRACE 2023
Average per facility	194,313 t/yr
Indicative carbon value	€161M/yr	at €75.36/t CBAM

📦 Iron & steel is a CBAM sector. EU-bound exports from Thailand pay the border price on the 2026→2034 phase-in — how CBAM works.

No carbon-pricing instrument is tracked for this country on this hub — exporters of CBAM goods to the EU still pay the border price with no domestic deduction.

Inzonex removable modular insulation on industrial equipment

Cut the tonnes at the source

Hot industrial equipment? Cut the heat loss.

Boilers, kilns, heat exchangers, valves and steam lines lose energy continuously. Inzonex makes patented (UK GB2508992.1) removable modular insulation — snap-fastened covers engineered per temperature tier, not generic off-the-shelf jackets:

Up to 90% less heat loss from insulated surfaces
Surface temperature ≤45 °C — touch-safe for workers (EN ISO 13732-1)
6× faster maintenance access than fixed cut-and-weld lagging — unclips and refits in minutes, no destruction
Inspectable — comes off to check for corrosion under insulation, then refits like-new (generic jackets often don't survive removal)
Typical payback under 2 years (some 9–11 months)

FAQ

Questions

How many iron & steel facilities does Thailand have with tracked emissions?

11 facilities carry satellite-based CO2 estimates in our dataset (Climate TRACE 2023), totalling ≈2,137,439 t CO2/yr.

What is the largest iron & steel emitter in Thailand?

Chow Steel Kabinburi Steel Plant — ≈1,646,539 t CO2/yr (est. 2023). Estimates are modelled, not verified declarations.

What would this CO2 cost at the CBAM price?

≈€161M per year at €75.36/t — indicative full-price value; actual cost depends on the EU-bound export share.

How this page is built: heat-loss figures follow ASTM C680 / ISO 12241 (the method behind our public calculators); facility emissions from Climate TRACE & EU ETS verified data across 30,000+ industrial sites; the 2026–2034 schedule is Regulation (EU) 2023/956, not a forecast.
