Protected Bicycle Lanes Protect the Climate

October 2022


As part of ITDP’s global Cycling Cities campaign and with support from the FIA Foundation, this report finds that networks of protected bicycle lanes in middle-income cities reduce greenhouse gas emissions, lower transport costs, and prevent premature road fatalities in a highly cost-effective way. 

Connected networks of physically-protected bicycle lanes, rather than disconnected, unprotected lanes or other policy measures, are the most important factor in increasing cycling usage. This study provides quantitative evidence to support this by examining the impacts of citywide networks of protected bicycle lanes in two cities in middle-income countries — Bogotá, Colombia and Guangzhou, China.


The findings of this research also enables anyone to model the climate impacts that a bicycle lane network would have in their city.

ITDP developed a free interactive modeling tool to predict the impact of any proposed bicycle lane development, which is available to download via Microsoft Excel.
