Summary of the work:

Policy brief written to outline 7 actions that local and national governments can take to advance and scale up the use of renewable energy in public transport. Shifting people to public transport that runs on renewable energy is one of the fastest and most cost-effective ways to reduce emissions and improve local air quality. It is a fundamental solution to address both climate change and public health concerns. However, the crucial link between renewables and public transport has been largely ignored. A variety of solutions exist for affordable, accessible and safe public transport to run on renewable energy. In many cases these solutions are ready to be implemented.
