Sustainable Digital Finance in Central Banking

Abstract

Abstract The role of central banks in advancing sustainable (“green”) digital finance is becoming increasingly significant, positioning them as both facilitators and key actors. This chapter begins by examining how climate-related financial risks may require adjustments to the operational frameworks of central bank policy tools, and highlights recent initiatives undertaken by central banks in response. It then reviews specific cases of sustainable digital finance in the central banking context, including: (1) the BIS’s Project Genesis, which integrates the green bond market and carbon markets through digital technologies; and (2) the collaboration between the Bank of Korea (BOK) and the Korea Exchange (KRX) to explore the application of distributed ledger technology and central bank digital currency (CBDC) in carbon trading.
