Izmir Metropolitan Municipality has used Google‘s EIE Transportation Emissions and Trips data to better understand their transport sector‘s carbon footprint and the mobility patterns of citizens. EIE is a tool utilising various data sources and modelling capabilities to assist cities in assessing emissions sources, conducting analyses, and formulating strategies for impactful actions. The EIE five-year data from 2018 – 2022 allows the city to have complete information on trips occurring in the city, including private vehicles, buses, bikes, motorcycles, and ferry data. It also identifies low-carbon mobility options that inform the Sustainable Urban Mobility Plan (SUMP) and the Carbon Neutrality Roadmap.
