ESG Management
ESG (Environmental, Social, Governance)
What is ESG management?
- Considering environmental, social and governance factors together
- Sustainability beyond finance
- Greenwashing (promotion only) backfires
When ESG arrives, the first thing to change is not the report but the transaction paperwork. Supplier greenhouse gas emissions and industrial accident rates appear on the purchasing scorecards of automakers and major electronics companies, and bank loan reviews and institutional investor due diligence ask for the same data. In practice, the real work is bringing numbers held separately by finance, procurement and safety teams into a single system. It starts not with polishing promotional copy but with creating data that didn’t exist and assigning owners to manage it.
E, S and G don’t carry equal weight. Manufacturers lose points first on E, service and retail companies on S (labor, suppliers, personal data), and listed companies on G (board independence, internal controls). Greenhouse gases are also split into Scope 1, 2 and 3. Direct emissions (1) and electricity use (2) can be calculated from bills, but Scope 3, which comes from raw materials, logistics and suppliers, takes time because you must collect data from your trading partners. In Korea, sustainability report disclosure is being phased in, starting with large listed companies, and exporters face regulations that require proof of product-level emissions directly, such as the EU Carbon Border Adjustment Mechanism.
If you confuse it with CSR, even your budgeting goes off track. CSR is about where you spend a portion of your earnings, so it is handled as a social contribution budget. ESG is risk management of the earning process itself, so it translates into equipment investment, process improvement and board operating rules. No matter how many year-end volunteer photos you put in a report, your supply chain due diligence score won’t rise by a single point.
The most common failure in the field is outsourcing the report. A company spends tens of millions of won on an impressive sustainability report, but without raw data in-house, the numbers don’t add up when a customer asks for verification the following year. A single mismatched figure invites greenwashing suspicion, leading to lost points or a repeat audit. The opposite mistake is also common: chasing ratings and trying to fill in every rating agency’s questionnaire, while missing the company’s biggest real risks, such as supplier safety accidents or chemical management.

Let’s walk through a hypothetical case. Company A makes auto parts and is a Tier 1 supplier with 320 employees and annual revenue of KRW 120 billion (≈ US$89,780,000). Its automaker customer has told it to reply within 60 days to a supply chain ESG due diligence request. But neither its greenhouse gas emissions nor its supplier safety inspection records were compiled anywhere in the company.
- The head of management support opened the 142-item due diligence questionnaire and found 87 items marked 'no data.' The head told the CEO: "If we reply as is, our supplier rating drops a notch."
- An energy manager gathered two years of electricity and city gas bills and calculated Scope 1 and 2 emissions: 8,400 tCO2e a year, 62% of it from the drying ovens on the paint line.
- The safety manager personally walked the night-shift sites of six suppliers. Near-miss incidents had gone unrecorded for two years, so the manager built a monthly reporting form and collected 23 reports in the first month alone.
- The ESG task force was moved out of the PR team and placed directly under the CEO, and a standing agenda item was added so that emissions, accident rates and supplier payment days are reported to the board every quarter.
- It invested KRW 280 million (≈ US$209,500) in waste heat recovery equipment for its drying furnaces, cutting gas use by 18% and saving KRW 110 million (≈ US$82,300) a year in energy costs.
- Its repeat audit score rose from 58 to 81, restoring its supplier rating from B to A, and the following year it won KRW 4 billion (≈ US$2,992,700) in new EV parts orders.
