The main objective of the LIFE GIOCONDA project is to provide local authorities with an innovative methodology that can effectively support policies on environment and health, by involving young people in decision-making processes. Data relating to air and noise pollution conditions will be collected in four project cities: Napoli, Taranto, Ravenna and Valdarno. This will be combined with data assessing the risk perception of teenagers, and their willingness-to-pay for local services related to environmental health issues, in order to develop and test an online platform to facilitate the application of environmental and health risk governance and policies. The platform will include a tool that allows decision makers to estimate costs and benefits of policies involving air pollution and/or noise exposure reductions that target young people s health, and a tool that enables schools to measure the pupils perception of their surrounding environment
