One-third of total urban greenhouse gas emissions in major cities is generated by transport. Reducing urban mobility emissions therefore provides a significant opportunity to decarbonise our cities (source). However, it requires citywide integration, network development and full supply chain innovation. Innovative business models and pioneering technology can enable cities toward achieving net-zero targets. BwB has been developing finance solutions in this area that include a range of payment mechanisms, co-benefit analysis and funding structures to meet the aspirations of cities, countries and citizens.
