The Climate Action Plan for Puerto Vallarta in the state of Jalisco shows that municipal adaptation and mitigation measures are not exclusively the task of the environmental unit at city hall. Each directorate has to be aware of its role in the fight against climate change, incorporate climate change into planning processes and utilise and steer resources and efforts so that development targets are achieved and are not jeopardised in the context of the major challenges posed by climate change (e.g. flooding as an infrastructure risk). VICLIM supported the city in drawing up its climate plan.
