Transport is Gävle's largest source of emissions, yet governing private, industrial, and commuting-related mobility requires tools and trust that don't yet exist at scale. This pilot launches a dedicated transport portfolio within Gävle's Climate City Contract, bringing together haulers, transport buyers, logistics companies, and public sector actors to collectively tackle freight decarbonisation. Simultaneously, Lund University is building an agent-based simulation model to optimise regional EV charging infrastructure investments — combining grassroots coalition-building with cutting-edge data modelling. Year 1 delivered both technical infrastructure and strategic insight. Lund University built a full MATSim transport simulation model combining local fleet data with Sweden's national freight model to test charging infrastructure scenarios before capital is committed.
