What is CDP

What is CDP?

CDP operates the world’s only independent environmental disclosure system.
Through CDP, more than 540 Capital Markets Signatories and more than 270 major buyers request companies and suppliers to disclose environmental data on climate change, water security, forests, biodiversity, and plastics. As of 2025, more than 22,100 organizations worldwide, including 682 Korean companies, disclose key environmental data through CDP.

How CDP works: investors and customers request environmental data through CDP from companies and suppliers

KoSIF : Secretariat of the CDP Korea Committee

KoSIF serves as CDP’s Korea partner and the secretariat of the CDP Korea Committee, which has led the CDP programs in Korea since 2008. Starting with climate-related disclosures from Korea’s 50 largest listed companies, our coverage has expanded steadily, including the introduction of water security disclosure in 2014.
Through CDP, KoSIF supports Korean companies and financial institutions in responding to global environmental disclosure expectations. We also promote the use of environmental data across companies, financial institutions, and market stakeholders.

Why Supply Chain Data Matters

Enabling a Sustainable Future

For many companies, the largest environmental risks lie not in direct operations but across their supply chains. Scope 3 emissions are, on average, significantly higher than operational emissions, making supplier-level data and engagement essential for net-zero strategies.

Stay Ahead of Regulation

Major disclosure frameworks and regulations, including the EU CSRD and IFRS S2, increasingly require Scope 3 emissions disclosure, making supplier-level data essential for regulatory readiness.

Future-Proof Your Operations

CDP Supply Chain helps companies collect standardized supplier data, identify risks and opportunities, and strengthen resilience across their value chains.

At a Glance (2025)

As expectations from investors, regulators, and customers continue to grow, the ability to collect and use supply chain data is becoming an important source of corporate competitiveness. CDP Supply Chain provides a practical channel for companies to strengthen supply chain transparency, manage Scope 3 emissions, and respond to global disclosure expectations.
