New technologies are enabling a completely new and, above all, sustainable form of mobility in our urban centers. But how far have the major metropolises already come on their journey towards climate-neutral and efficient mobility that makes our cities even more livable? What are the hurdles and success factors? And how can we measure whether we are on the right path? The Sustainable Mobility Readiness Index (SMRI) offers answers and guidance. We want to discuss our experiences with mayors, city planners and public transport executives in a high-level panel.
