An expert in urban development, local environmental policies, and international policies on migration and climate, Caterina Sarfatti is director of the Inclusive climate action program of the international organization C40 Cities Climate Leadership Group. The intent of the program is to provide support to cities to plan and implement interventions against the climate crisis. In particular, we focus on creating plans that are fair and inclusive: which therefore take into account the needs of all strata of the population (not just the privileged classes). According to the United Nations, it is the vulnerable and marginalized categories that suffer most from the consequences of the climate crisis, risking to slip below the poverty line.
