International Banking regulations (i.e. Basel Capital Accord) have gained much attention in the aftermath of the financial crisis. Simultaneously, interest in environmental risks for banking and their potential systemic impacts are also on the rise. The author highlights some initial programs (i.e. Brazil, China, Peru), where banking regulation and governance practices address environmental risks. This report concludes that the Basel Committee should learn from these experiences and consider reforms to the Basel III Pillar 2 Supervisory Review framework and the Pillar 3 Market Discipline framework, by recognising systemic environmental risks as material risks which can potentially threaten banking stability.
