Locking in positive climate responses in cities

Cities are home to much of the world’s population and are key actors in climate mitigation and adaptation efforts. Many have stepped forward to show climate leadership, but it is not clear whether urban strategies for adaptation constrain or facilitate mitigation, and vice versa. Efforts to understand, develop and implement adaptation and mitigation strategies typically operate in silos, with limited interaction. Despite the increased prevalence and ambition of city-level mitigation and adaptation plans, there are few efforts aiming at creating synergies or avoiding trade-offs between them.We thank G.
