ESG Disclosure Mandate Becomes Reality
In February 2026, the Korean government announced the ESG disclosure mandate roadmap, gathered stakeholder input through March, and finalized it in April. ESG disclosure will become mandatory starting with listed companies with assets over 2 trillion KRW.
You might think, "We're not listed or large—why should we prepare?" However, the supply chain effect directly impacts SMEs.
Impact on SMEs: The Supply Chain Cascade
Surge in Scope 3 Data Demands from Large Corporations
Large companies need Scope 3 (supply chain emissions) data for ESG disclosureFrom 2026, cases of including supplier carbon data submission as contract requirements are surgingRisk of contract termination or evaluation penalties for non-submissionReal Cases
Auto parts suppliers: Carbon emission verification required for overseas OEM contractsElectronics suppliers: Supplier environmental data reflected in corporate ESG evaluationsFood/materials: CBAM certificate submission mandatory for European exports5 Things SMEs Must Prepare Now
1. Build Carbon Emission Measurement Systems
The first priority is to understand your company's carbon emissions.
Scope 1 (Direct Emissions)
Fossil fuel combustion from company-owned equipment (boilers, vehicles)LNG, diesel, gasoline usage → CO₂ conversionScope 2 (Indirect Emissions)
Emissions from purchased electricity and steamElectricity usage × emission factor calculationHow to Execute:
Use the SME Carbon Neutrality Platform (Ministry of Environment) for freeEstablish monthly data collection for energy usageUtilize initial assessment support through consulting firms2. Implement ESG Data Management Systems
Transition from Excel-based management to systematic data management.
Energy usage: Automatic monthly collection of electricity, gas, and fuelWaste output: Data management by type and disposal methodWater usage: Separate process and domestic water trackingSafety & health: Industrial accident rates, training hours, etc.Recommended Tools:
Government-supported carbon data platform (planned for 2026-2027)SaaS-based ESG management solutions (hundreds of thousands KRW/month)Custom spreadsheet templates (for smaller companies)3. Prepare for Supply Chain Carbon Data Sharing
Be ready to immediately respond to data requests from large corporate customers.
Pre-identify required data formats by customerBuild product-level carbon footprint calculation capabilitiesEstablish automated reporting systems (API integration, etc.)4. Invest in Energy Efficiency
Carbon emission reduction directly translates to cost savings.
Immediately Actionable Measures:
LED lighting replacement (30~50% energy savings)High-efficiency motor and inverter replacementCompressed air leak inspection (15~25% of energy waste)Waste heat recovery systemsGovernment Support:
SME energy efficiency equipment subsidies (up to 50~70%)Carbon neutrality commercialization support programsGreen finance low-interest loans5. ESG Capability Building Education
ESG requires company-wide understanding from executives to shop floor workers.
Executives: ESG strategy, regulatory trends, risk managementManagers: Data collection/reporting, improvement task managementShop floor: Energy conservation, waste separation, safety protocolsResponse Timeline by Roadmap Phase
| Timing | Target | SME Actions |
|--------|--------|-------------|
| April 2026 | Roadmap finalized | Internal assessment, assign responsible person |
| H2 2026 | Disclosure standards set | Build data collection systems |
| 2027 | 2T+ KRW companies prepare | Customer data requests intensify |
| 2028 | Mandatory disclosure starts | Supply chain data submission response |
