About This Project

SDG 11 - Sustainable Cities SDG 13 - Climate Action

Transport is one of the biggest sources of carbon emissions in Ireland. In Dublin alone, private cars account for over 60% of all commuter journeys, contributing significantly to air pollution and greenhouse gas emissions. This website explores sustainable alternatives: cycling infrastructure, the Luas tram network, and Dublin Bus, and the impact they are making on the city's carbon footprint.
