Corporate sustainability management is increasingly viewed as a key management theme every corporation must pursue, and investors pay close attention ever to the sustainability performance of the investee companies.

GSIA ( Global Sustainable Investment Alliance )
Non-financial factors such as governance structures, employees, partners, and the environment increasingly impact corporate value and growth. By preventing and managing non-financial risk through sustainability management, companies can balance financial and non-financial growth and enhance access to capital markets including the steadily growing responsible investment market.

KCGS has conducted an evaluation of corporate governance since 2003 based on a high level of transparency and expertise. In 2011, it adopted an annual ESG evaluation adding social responsibility and environmentally responsible management to measure the level of sustainable management by the listed companies in Korea.
Through ESG evaluation, KCGS aims to help listed companies understand where they are in sustainability management and seek improvement where necessary. The ESG evaluation model has been developed by KCGS independently, not only aligned with international standards such as the OECD principles on corporate governance and ISO26000, but also faithfully reflective of legal and management circumstances in Korea.
