Since 2003, the Korea Institute of Corporate Governance and Sustainability (KCGS) has conducted corporate governance assessments based on expertise and transparency. Through ESG evaluations, which include social responsibility and environmental management, KCGS has assessed the sustainability management level of domestic publicly listed companies annually since 2011.

The objective of KCGS's ESG evaluation is to assist listed companies in assessing and enhancing their current sustainability management level. Its independent ESG evaluation model conforms to international standards, such as the OECD Principles of Corporate Governance and ISO 26000, as well as the domestic legal and business management environments.

Sustinvest comprehensively evaluates the level of ESG risk management of domestic companies, assisting in the selection of outstanding companies from a sustainability perspective. ESGValue™, an ESG evaluation model developed by Sustinvest in 2007, reflects the ever-evolving and expanding domestic and international ESG discourse.

Sustinvest's ESG data and evaluation results indicate that investors making sustainable investment decisions that take into account both financial and non-financial ESG factors will serve as a major force in achieving a sustainable society.

The goal of MSCI ESG Ratings is to evaluate a company's management of financially relevant ESG risks and opportunities. MSCI identifies industry leaders and laggards based on their exposure to ESG risks and how well they manage these risks relative to their peers using a rule-based methodology.

MSCI ESG Ratings range from leaders (AAA and AA), average (A, BBB, and BB) to laggards (B and CCC). MSCI also evaluates equity and fixed income securities, loans, mutual funds, ETFs, and countries.

The CDP is a non-profit organization that operates a global disclosure system to aid in the management of environmental impacts. Each year, it assists tens of thousands of businesses, municipalities, states, and regions in assessing and managing risks and opportunities associated with climate change, water security, and deforestation.

The global economy recognizes the CDP as the gold standard for environmental reporting, as it provides the richest and most exhaustive data on business and city government activities.
