Professor Greg Marsden presented on place-based transport decarbonization. He discussed how different places have different functions, transport systems, built environments, populations, and cultures, which leads to huge variations in factors like car carbon emissions between areas. His research aims to understand these differences and identify different pathways, speeds, and costs to reduce surface transport emissions by 2030, 2040, and 2050. The DecarboN8 project addresses these challenges through four research themes, pilot projects, policy briefings, events, and proposals for major demonstrations to decarbonize transport in different local contexts.
