Overview

The assessment of impacts and costs of climate change has largely focused on loss and damage to ‘hard ’ (e.g., , infrastructure, and other hard engineered assets) and the resulting loss of services (e.g., public transportation delays, power outages and water and sewage disruptions). However, municipal , which plays a key role in mitigating the impacts of climate change, is also vulnerable to its impacts. Particularly when not designed or maintained properly, green infrastructure is subject to contamination, damage from debris, and other climate hazard-related impacts. Damage to green infrastructure may require costly restoration or replacement that temporarily reduces its capacity to mitigate climate impacts, or, if left unrestored, can compromise long-term .
