For the urban transportation sector—one slice of the climate-change equation—the road to keeping below 1.5°C global warming involves both compact cities developed for walking, cycling and public transit, as well as a rapid and strategic transition to electrified vehicles. This report details why these two policy changes, implemented in tandem, are necessary to lower cumulative greenhouse gas emissions from urban passenger transport by 59 gigatonnes (Gt) CO2-eq by 2050. This combination of policy changes would

Rapid transit is the backbone of public transportation, especially in large cities, because it allows people to travel quickly between different neighborhoods. It functions best as part of a larger urban mobility system that includes walking and cycling. The Rapid Transit Database (RTDB) presents all publicly available data about every rapid transit line in the world. ITDP maintains the RTDB and updates it annually. Explore the database here. 

Demand for and use of private cars is growing worldwide, contributing to major challenges like poor air quality, traffic injuries, and climate change, especially in places experiencing rapid urbanization. Population growth and uptake of vehicles, coupled with inefficient public transportation and land use planning, make traffic a complex problem to manage. While many city leaders recognize that traffic is a problem, they too often focus on road expansions and new highways as the solutions. Not
