Background and aim Differential exposure to multiple environmental factors social deprivation can enhance health vulnerabilities thus limit the exposed population's capacity adapt climate change. We aimed identify hotspots of cumulative urban heat island, air pollution, deficit green spaces in continental France describe their evolution between 2000 2018. Methods Daily gridded minimum, mean maximum temperature PM2.5, PM10 NO2, were estimated based on validated models with high spatial resolution (200m 1km). Winter summer NDVI (Normalized Difference Vegetation Index) was using Landsat satellite images a 30m resolution. Over-exposure temperature, pollution assessed by defining thresholds for each indicator that are potential underlying risks. WHO quality guidelines used define over-exposure pollution. For spaces, reference values defined department type urbanization rate. The frequencies exceedance days temperatures, PM10, PM2.5 NO2 concentrations over year calculated combined altogether indicator. differential related deprivation, through European Deprivation Index (EDI) French (FDep), studied distributions comparison methods. Conclusion This study will provide first picture fine scale stress its co-exposures at national scale. work could be effect greenspace outcomes.
