A autoridade europeia do mercado de capitais, ESMA, está propondo que o risco climático seja uma nova categoria de risco, ao lado dos já existentes (liquidez, mercado, crédito, contágio e operacional), sendo identificado três grupos: mudança no sentimento do mercado, lavagem verde e riscos relacionados com o clima. Regulators and supervisors have started to incorporate environmental risks, especially those stemming from climate change, and their potential implications for the financial system into their work. The objective of this article is twofold: first, to depict how environmental risks can be expected to impact EU securities markets and their participants; and second, to lay out ESMA’s approach to integrating environmental risks in the risk assessment and monitoring framework. In light of ESMA’s financial stability, investor protection and orderly market objectives, and given the unique nature of climate risks and the challenges they entail for risk monitoring purposes, we propose to integrate climate risk as a new risk category alongside the existing liquidity, market, credit, contagion and operational risk categories. This risk category is intended to capture physical and transition risk drivers and their mitigants, in addition to the potential risks associated with green finance. As part of this framework, at the current juncture we identify three core risks to ESMA’s objectives stemming from climate change: abrupt changes in market sentiment, greenwashing and weather-related hazards.
