As ESG disclosure takes centre stage, transition execution is becoming a key corporate differentiator

ESG disclosure in Korea is about to enter the stage of institutionalisation. Since the Financial Services Commission released its draft disclosure roadmap in February, companies have faced growing pressure to adequately prepare for the final announcement, which is expected to address key issues such as the scope of companies subject to disclosure, the implementation timeline, and whether Scope 3 emissions will be included.

However, what companies should focus on now is not who needs to disclose or when it should be implemented – it is how to use this as an opportunity to articulate their company’s value through the right language and framework. ESG disclosure is a core management agenda that is directly linked to capital markets, competitive supply chain positioning, and financing. Ultimately, the key lies in presenting a company’s transition capabilities in a way that the market can understand and evaluate.

ESG disclosure can serve as a starting point for building trust with capital markets and supply chains. However, disclosure alone does not necessarily secure corporate competitiveness. More importantly, the key question which the market is asking is whether the disclosure is connected to a company’s actual transition plan, financing strategy, and execution framework. Companies now need to move beyond a passive response to disclosure requirements and assess how they can demonstrate their “ability to execute transition”. When the disclosure framework becomes a credible infrastructure and operates consistently within the company’s transition plan and organisational operating system, companies will be able to implement and undertake sustainable finance in a more concrete way.

To achieve this, the first factor companies should consider is securing trust in the global market, in other words, international alignment. A disclosure framework must be designed not to satisfy domestic regulations, but to standards that global investors, financial institutions, and supply chain stakeholders can also understand and benchmark against. This is particularly important for companies with a high share of exports, as their disclosure information must be understood by and compared within the context of demanding global supply chains. Major economies around the world have already begun to recognise the ISSB as a reference point for designing sustainability disclosure frameworks, while global investors and financial institutions are also assessing companies’ transition capabilities based on ISSB standards. For this reason, Korea’s disclosure roadmap has also been developed based on the ISSB’s IFRS S1 and S2 standards.

Second, companies need to communicate in the language of capital markets, articulating their transition narrative in investor dialogues. Disclosure data must go beyond merely presenting or reporting the current status of affairs but should extend to sector-specific transition pathways energy procurement structures, and evaluating how supply chain risks might affect future cash flows. In particular, for carbon-intensive industries, the investment plan and financing structure required to implement emissions reduction targets are as important as the targets themselves.

Finally, what is needed is an enterprise-wide approach and robust internal controls.  ESG disclosure is not a one-time reporting exercise but an ongoing information infrastructure, and companies must enhance the credibility of their disclosure frameworks through an enterprise-wide approach that encompasses climate data management systems, internal controls, and governance. Given that the sustainability disclosure standards of the KSSB (Korea Sustainability Standards Board) are structured around governance, strategy, risk management, and metrics and targets, companies must establish internal systems capable of collecting and verifying relevant data and incorporating it into decision-making.

When the disclosure framework operates consistently within the company’s transition plan and broader organisational operations, representative sustainable finance instruments such as sustainability-linked loans and green bonds can also be implemented in a more concrete manner. Companies must be able to explain what capital expenditure, technology development, process improvements, and supply chain restructuring they will pursue to achieve their targets, and how they will establish the financial foundation required to implement them. Only then can they secure the trust of the market. Companies that go beyond mere disclosure compliance to demonstrate real transition execution capabilities will be positioned to earn greater trust from investors, financial institutions, and global supply chains.
