01What is EU CBAM and Why It Matters for Malaysia
The Carbon Border Adjustment Mechanism (CBAM) is the European Union's landmark policy to prevent “carbon leakage” — the practice of companies relocating carbon-intensive production to countries with weaker climate regulations. Under CBAM, EU importers must purchase “CBAM certificates” proportional to the embedded carbon emissions in goods they import from non-EU countries.
CBAM certificates are priced to match the EU Emissions Trading System (EU ETS) carbon price — currently trading at EUR 55–70 per tonne of CO2 equivalent (tCO2e) in Q1 2026. The key variable is the “embedded emission intensity” of your product — measured in tCO2e per tonne of output.
For Malaysian manufacturers, this creates a direct financial incentive to reduce the carbon intensity of their production — particularly the Scope 2 emissions from electricity consumption. Malaysia's TNB grid has an emission factor of approximately 0.740 tCO2e per MWh for Peninsular Malaysia (Suruhanjaya Tenaga, 2024 (provisional)), one of the higher emission factors in Southeast Asia. Solar electricity you generate and use on site avoids that grid factor for the share of your load it covers.
The CBAM Cost Formula
Malaysia's disadvantage: Because Malaysia does not yet have a mandatory carbon pricing mechanism, the full EU ETS carbon price applies to embedded emissions in Malaysian exports — with no offset or credit. Every tonne of CO2 embedded in your product costs your EU buyer up to EUR 60 in CBAM certificates at the full rate. The charge phases in from 2026 as free EU ETS allowances are withdrawn and reaches 100% of embedded emissions in 2034. Reducing your emission intensity is the only way to reduce this cost.
02Which Malaysian Industries Are Affected
CBAM's initial scope covers six product categories. Malaysia is a significant exporter in several of these, particularly aluminum products, steel pipes and tubes, and fertilizers.
| CBAM Sector | Key Malaysian Exporters | Typical Emission Intensity | CBAM Cost/tonne Output (at full rate, 2034) |
|---|---|---|---|
| Iron & Steel | Hiap Teck, Southern Steel, Mycron Steel | 1.8–2.5 tCO2e/tonne | EUR 108–150/tonne |
| Aluminium | Press Metal, Alcom, Aluminium Extrusions | 6–12 tCO2e/tonne | EUR 360–720/tonne |
| Cement | YTL Cement, Lafarge Malaysia, CMSB | 0.8–0.9 tCO2e/tonne | EUR 48–54/tonne |
| Fertilizers | Malaysian fertilizer producers | 1.2–3.0 tCO2e/tonne | EUR 72–180/tonne |
| Hydrogen | PETRONAS, emerging green H2 projects | 0–10 tCO2e/tonne | EUR 0–600/tonne |
| Electricity | Power grid cross-border (limited scope) | Grid-dependent | EUR/MWh equivalent |
Even if your company is not directly in a CBAM-regulated sector, you may face indirect CBAM pressure. EU OEMs in automotive, construction, and industrial equipment are increasingly requiring their Tier-1 and Tier-2 Malaysian suppliers to provide Scope 3 emission data and demonstrate decarbonization roadmaps. Companies that cannot provide verified emission data risk being de-listed from European supply chains.
| Period | Status | Obligation for Malaysian Exporters |
|---|---|---|
| Oct 2023 – Dec 2025 | Transitional | Quarterly embedded emission reporting (no financial penalties). EU importers submit reports. |
| Jan 2026 onwards ← NOW | Definitive period | Only authorised CBAM declarants may import. Embedded emissions in 2026 imports must be covered by CBAM certificates, which are sold from 2027. |
| 2026–2034 | Ramping Up | Free EU ETS allowances phased out — CBAM burden increases annually as EU ETS free allocation drops. |
| 2034 onwards | Full CBAM | Zero free EU ETS allowances — full CBAM cost on 100% of embedded emissions. |
03How Solar Reduces Your CBAM Exposure
The embedded emissions in your products are calculated using your total greenhouse gas emissions divided by production output. Electricity from the TNB grid is the main source of Scope 2 emissions for most manufacturers. Solar electricity used on site displaces that grid electricity for the share of your load it covers — it has a lifecycle emission factor of approximately 20–40 gCO2e/kWh, versus 740 gCO2e/kWh for the Peninsular grid. Under the CBAM Regulation, indirect emissions from electricity count towards the CBAM charge only for cement and fertilisers; for iron and steel, aluminium and hydrogen only direct emissions are charged. For those sectors solar still lowers your electricity bill and Scope 2 footprint, but not the CBAM certificate cost itself.
Illustrative arithmetic: 500 kWp Solar on an Electricity-Intensive Plant (where indirect emissions are in scope)
Compounding value: As the EU ETS carbon price is projected to rise to EUR 80–100/tCO2e by 2028–2030, and as CBAM free allowances are phased out, the CBAM savings from solar become proportionally larger over time where indirect emissions are in scope. Carbon-price projections are estimates, not guarantees.
04RECs: Documenting Your Renewable Generation
Your solar generation can also be registered for Renewable Energy Certificates (RECs) through a recognised REC registry. Each REC represents 1 MWh of renewable generation and can be kept for your own market-based Scope 2 and ESG reporting, or sold. RECs are not carbon credits, and they do not by themselves change how CBAM calculates indirect emissions — confirm the treatment with your EU importer and its verifier.
Register your solar system with a recognised REC registry. For every MWh generated, one REC can be issued.
REC prices vary by registry, buyer and contract. Ask the registry or buyer for current prices before counting on REC income.
A 1 MWp solar system generates roughly 1,260 MWh a year in this guide's example, so roughly 1,260 RECs. Trexon provides the monitored generation data.
| System Size | Annual Generation | RECs/Year | Scope 2 Reduction (0.740 t/MWh) |
|---|---|---|---|
| 200 kWp | 252 MWh | 252 | 186 tCO2e |
| 500 kWp | 630 MWh | 630 | 466 tCO2e |
| 1 MWp | 1,260 MWh | 1,260 | 932 tCO2e |
| 2 MWp | 2,520 MWh | 2,520 | 1,865 tCO2e |
| 5 MWp | 6,300 MWh | 6,300 | 4,662 tCO2e |
05ESG Reporting: Bursa Malaysia Sustainability Obligations
Bursa Malaysia has progressively strengthened sustainability reporting requirements for listed companies. As of 2026, Main Market listed companies must publish Climate-Related Disclosures aligned with TCFD (Task Force on Climate-related Financial Disclosures), including Scope 1, Scope 2, and material Scope 3 emissions.
| Company Category | Disclosure Requirement | Effective Date | Solar's Role |
|---|---|---|---|
| Main Market (Top 100 by market cap) | TCFD-aligned climate-risk disclosures (check Bursa's current requirements) | From FY2026 (phased) | Reduces reported Scope 2 intensity; mandatory for investor credibility |
| Main Market (all others) | Sustainability Statement (per Bursa's current requirements) | Per Bursa timeline | Lower absolute Scope 2 figure improves ESG rating |
| ACE Market listed | Sustainability Statement | Comply-or-explain | Demonstrates low-carbon trajectory to investors |
| Non-listed (EU supply chain) | CBAM embedded emission reporting (via EU importer) | Jan 2026 (active) | Lower CBAM certificate cost where indirect emissions are in scope (cement, fertilisers) |

065-Step CBAM-Proof Your Factory Action Plan
Map Your Embedded Emissions
Commission a Scope 1, 2, and 3 GHG inventory for your factory. Identify which production processes have the highest embedded emission intensity per tonne of output. This becomes your CBAM calculation baseline.
Engage an accredited carbon accountant or CBAM verifier.
Quantify Your CBAM Exposure
Based on your EU export volumes and embedded emission intensity, calculate annual CBAM certificate cost at current EU ETS price. This provides the financial justification for your decarbonization investment.
Use the formula: Annual Exports (tonnes) × Emission Intensity (tCO2e/tonne) × EUR 60/tCO2e × RM/EUR rate (this is the full-rate cost; the charge phases in until 2034).
Deploy Industrial Solar (Priority: Scope 2)
Scope 2 emissions from electricity are usually the easiest to reduce. Rooftop solar displaces grid electricity for the share of your load it covers; how much depends on your roof and load profile. It lowers the CBAM certificate cost only where indirect emissions are in scope (cement, fertilisers).
Request a site assessment from Trexon Energy for the solar sizing and energy-cost savings case.
Consider RECs for ESG Reporting
Register your solar system with a recognised REC registry if RECs suit your ESG or customer reporting. Check with your EU importer and its verifier how (or whether) they are recognised for CBAM before relying on them.
Trexon provides the system generation data the registry asks for.
Provide Embedded Emission Reports to EU Buyers
Give your EU buyers accurate embedded emission data (including your electricity source data where indirect emissions are in scope). Without your actual data they may have to use default values, which are usually higher.
Trexon can export your solar system's monitored generation data for your emissions reporting.
“CBAM has permanently changed the calculus for Malaysian exporters. Carbon is no longer an externality — it has a price, enforced at the EU border. Factories that cut grid electricity use will lower their Scope 2 intensity; whether that lowers CBAM cost depends on the product sector. Worth modelling now.”
