Monitoring Climate Risk: The evolution of Climate Indices and their application in Risk Management

This study provides an in-depth analysis of climate change, examining its multifaceted impacts on ecosystems, society, and the global economy. Climate change disrupts interconnected systems, intensifying risks to biodiversity, food security, and public health, with substantial financial implications. Recognizing climate change as a financial risk, the study highlights the importance of adapting economic and risk management practices, especially as conventional methods struggle with climate’s unpredictability and dynamic nature. Focusing on Italy, the study addresses the “insurance gap” where coverage fails to meet the rising climate-related financial risks. It reviews recent public policy efforts, like Italy’s Budget Law, which aims to narrow this gap. However, policy alone may not suffice, and thus innovative insurance strategies are explored, especially through the use of climate indices. These indices, such as the European Extreme Events Climate Index (E3CI), the Actuaries Climate Index (ACI), and the Actuaries Climate Risk Index (ACRI), offer standardized, data-driven metrics that enhance risk assessment and allow insurers to provide more comprehensive, adaptable, and affordable coverage. By incorporating these indices, insurers can quantify risks with greater precision, allowing for a proactive and resilient approach to climate risk. In particular, the E3CI shows that extreme events have sharply increased in Italy, pointing to a heightened need for adaptive insurance measures, essential for managing climate risks in a constantly evolving environment.
