In view of the ever-increasing progress of climate change, the importance of climate risk assessments is growing. They play a major role at the municipal level in particular (cities, distriscts, municipalities), because it is here that precautionary action must take place in the face of the dangers of the climate crisis. The recommendations in this papier provide support for the preparation and implementation of climate risk assessments at the municipal level. They summarise the international standard: ⁠Adaptation⁠ to climate change-Guidelines on vulnerability, impacts and risk assessment (ISO 14091:2021-07) and supplement this general guideline with specific recommendations for municipalities.
