Tropical cyclones (TCs) can significantly hinder economic development for over a decade. This study quantifies the country-level social cost of carbon (SCC) induced by the persistent growth effects of damaging TCs, a factor not currently considered in SCC estimates. Using temperature-dependent damage functions for 41 TC-affected countries, the research finds that accounting for TC impacts increases the global SCC by over 20%, from US$173 to US$212 per tonne of CO₂ under a middle-of-the-road scenario. This increase is largely driven by major emitters like India, the USA, China, Taiwan, and Japan, highlighting the potential underestimation of climate policy benefits.
