Whether they are speaking in international forums, proposing ambitious goals to reduce emissions, or working hand in hand with their neighbors to achieve more sustainable urban settings, it is clear their agendas for climate change are a fundamental piece to their local administration. In this sense, urban climate action represents an opportunity, not only to offset the city footprint on the environment, but also to better the quality of life for all in cities.
