CBAM is no longer a warning — it's live
From 1 January 2026, the EU's Carbon Border Adjustment Mechanism (CBAM) entered its definitive phase. EU importers must now declare the greenhouse-gas emissions embedded in the goods they import and, over time, purchase CBAM certificates for them. The mechanism covers cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen.
Two dates matter more than the headline. Certificates only go on sale on 1 February 2027, and the first surrender — covering everything imported during 2026 — is due by 30 September 2027. So 2026 shipments accrue a cost that is invoiced later, which is exactly the window in which emissions data has to be collected rather than reconstructed.
There is also a threshold worth checking before anything else: since the October 2025 simplification, an EU importer bringing in 50 tonnes or less of CBAM goods a year is exempt altogether — around 90% of importers, though the exemption does not apply to hydrogen or electricity. If your EU customer sits under it, your CBAM conversation is about paperwork relief, not carbon cost.
For Thai exporters, this is no longer theoretical. Analysts estimate CBAM affects a low-single-digit share of Thailand's exports to the EU — worth on the order of tens of billions of baht per year — concentrated in steel and aluminium.
The real risk: not pollution, but proof
The commercial danger is subtle. A multinational buyer may ask a Thai supplier for verified electricity data, then for process-heat details, then for proof of renewable-energy use. A supplier can lose the bid not because it pollutes more, but because it cannot show its numbers with confidence.
CBAM turns carbon accounting into a condition of trade. Two things now matter:
- Lowering the embedded emissions of your product
- Proving the reduction with audit-ready data
Why onsite solar is the most direct lever
A large share of a factory's embedded emissions comes from purchased electricity — Scope 2. Grid electricity in Thailand still carries a significant carbon intensity, so every kWh you replace with your own renewable generation lowers your product's carbon number directly.
- Onsite solar rooftop — displaces grid electricity during production hours, cutting Scope 2 at the meter
- BESS — shifts more of that solar into the production profile and improves self-consumption
- A Direct PPA / green tariff — covers the remaining load with contracted renewable power
Proving it: MRV and verifiable reporting
Reduction only counts if it is measured and verifiable. A well-designed Solar + BESS system should produce an automated carbon report covering renewable generation and Scope 2 emissions avoided, built on TGO/IEA emission factors and ready for CBAM, T-VER and ESG disclosures.
The goal is a clean chain of evidence: metered renewable generation → Scope 2 avoided → a report your EU customer's auditors accept.
The upside: carbon-credit revenue (T-VER)
Compliance is not the only benefit. Thailand's voluntary emission-reduction programme, T-VER, lets qualifying solar projects register and sell carbon credits, with support available from agencies such as EXIM Thailand. Credit prices vary, but they add a second revenue stream on top of the electricity savings — turning an energy investment into both a cost cut and an income source.
A practical roadmap for a factory
- Baseline — measure current electricity use and grid-based Scope 2 emissions
- Design — size onsite solar + BESS (and consider a Direct PPA) against your real 15-minute load profile
- Install & monitor — commission the system with metering that feeds an automated carbon report
- Report & monetise — use the report for CBAM/customer disclosures, and evaluate T-VER credit registration
Where LEONICS fits
LEONICS designs Solar Rooftop + BESS + GridMind AI systems with automated carbon reporting built in — renewable generation and Scope 2 avoided, ready for CBAM, T-VER and ESG requirements. It is one system that both lowers your bill and documents your carbon story for export customers.
Frequently asked questions
Does CBAM apply to my products?
CBAM currently targets cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen. If you export these to the EU — or supply companies that do — you are within scope or part of the affected chain. Check your EU customer's volume first: an importer under 50 tonnes of CBAM goods a year is exempt (hydrogen and electricity aside), which takes about 90% of EU importers out of the mechanism.Can offsets alone satisfy CBAM?
CBAM is about the emissions embedded in the product itself, so actual reductions (such as onsite renewable electricity) carry more weight than offsets bought elsewhere. Onsite solar is directly attributable to your production.How much of my carbon footprint can solar cut?
It depends on how much of your load is electricity (Scope 2) and how much of it solar + BESS can cover. A feasibility study on your real load profile gives the figure.Is the reporting audit-ready?
A properly instrumented system produces metered generation data and Scope 2-avoided figures built on TGO and IEA emission factors — the basis auditors and EU customers look for.Getting started
The first step is to measure your real load and model how much Scope 2 solar + BESS can remove — then design the system and the reporting together. LEONICS offers a free Solar Insight Pro feasibility analysis for factories.
