# Thailand EV Supply Chain: MSME Decarbonisation for the BOI 30@30 Policy

Canonical: https://senseible.earth/climate-intelligence/thailand-ev-supply-chain-msme-2026

Published 2026-05-06.

Thailand's 30@30 policy targets 30% of vehicle production to be EVs by 2030. Several global automakers have committed EV manufacturing investment in Thailand. MSME suppliers face new carbon and content expectations.

## What 30@30 means for suppliers

- Government EV incentives come with local production commitments, pulling more component work into Thailand
- OEM customers increasingly ask suppliers for emissions data
- Battery suppliers exporting to the EU must prepare for the EU Battery Regulation's carbon footprint and passport rules

## The grid reality

Thailand's grid relies mainly on natural gas plus hydropower imported from Lao PDR, so its grid emission factor is lower than coal-heavy grids such as India's. That gives Thailand-assembled components a structural advantage on electricity-related emissions. Use the official Thai grid factor published by TGO and document its version.

## What Tier 2/3 MSMEs should do

1. Baseline electricity + LPG + diesel using [Senseible](https://senseible.earth/)
2. Check BOI incentives for eligible EV parts and energy-efficiency investments
3. Check PEA / MEA rules for rooftop solar
4. Submit emissions data through each OEM's supplier portal
5. Use [Logistics calculator](https://senseible.earth/calculators/logistics-emissions) to model EV vs ICE component freight

A cleaner grid is an advantage, but other countries are adding renewable capacity too. Rooftop solar and renewable supply contracts help Thai MSMEs keep their lead.

## Battery passport prep

The EU Battery Regulation requires EV batteries, light means of transport batteries and industrial batteries above 2 kWh placed on the EU market from February 2027 to carry a digital battery passport, with information including carbon footprint, recycled content and supply chain due diligence. Thai battery exporters need data collection systems running well before then.
