Extreme heat raises exit risk for Italian firms, study finds

extreme heat firm exit rate Italian agriculture climate risk micro‑enterprises

A research project titled “Do High Temperatures Affect Firm Demography? Evidence From Italy” analysed more than 100,000 Italian firms across five sectors between 2009 and 2022. It found that each summer day with temperatures between 29 °C and 32 °C increases the firm exit rate by about 0.014 percentage points, while days at or above 32 °C raise the rate by roughly 0.016 points. Micro‑enterprises and individual firms are the most vulnerable to these heat‑related exits.

The AGRIcoltura100 2026 report, based on a survey of over 3,800 Italian farms, showed that 67.6 % of agricultural enterprises suffered at least one climate‑related damage between 2023 and 2025. Luca Filippone, director general of Reale Group, warned that climate risk in agriculture has become a structural threat and calls for stronger prevention and risk‑management tools.

In Trentino, a downburst with wind gusts over 20 m/s damaged roughly 100 hectares of vineyards and fruit trees, causing an estimated loss of €2 million. The European Environment Agency estimates that extreme weather events have already generated more than €738 billion in economic losses across Europe from 1980 to 2023.
