The Children’s Climate Risk Index (CCRI) provides the first comprehensive view of children’s exposure and vulnerability to the impacts of climate change. It ranks countries based on children’s exposure to climate and environmental shocks, such as cyclones and heatwaves, as well as their vulnerability to those shocks, based on their access to essential services. This report presents a conceptual framework, a tool and an initial assessment at a global level of children’s exposure and vulnerability to climate and environmental hazards, shocks and stresses – in order to help prioritize action for those most at risk.
