Compact Climate Compliance (CCc) is a solution created by ICLEI South America to support municipalities with fewer than 200,000 inhabitants in promoting a sustainable territory, focusing on reducing Greenhouse Gas (GHG) emissions and increasing resilience to the climate crisis. Considering their specific characteristics, instead of promoting highly complex and consequently costly studies for municipalities of this size, analytical studies are carried out using publicly available data. In this way, compact CCc is structured by a governance system, GHG emissions analysis, and climate risk and vulnerability analysis. These steps are fundamental for the development of the compact Local Climate Action Plan (PLACc).
