In this WHO Science in 5 episode, Dr Etienne Krug, Director of Social Determinants of Health, shares examples of cities that are taking action on greener, more sustainable transport that can also help keep people healthier and safe. 

For example, Mexico City, Mexico, has increased cycling lanes while making roads safer; Cali, Colombia has sent out bike doctors to help repair bikes; and Lusaka, Zambia created safer routes for children to get to school.

Note: This episode was filmed onsite in Cape Town, South Africa, during the 2024 Partnership for Healthy Cities Summit that brought together more than 50+ cities to help prevent injuries and noncommunicable diseases.
