During the EUROGEO conference Lesvos 2022 “RE-VISIONING GEOGRAPHY FOR SUSTAINABILITY IN THE POST-COVID ERA”, an interactive, user-friendly, online GIS platform to monitor SDG Indicator 11.6.2 at the municipality scale was presented, allowing the identification of hot-spots that necessitate increased policy attention. The indicator refers to population weighted concentrations of fine particulate matter (PM2.5) and is here monitored for a 3-year period, as a demonstration of EO exploitation in support of the SDG frame.
