50 climate solutions from cities in the People's Republic of China


Wuhan unveiled one of the world’s largest bike-sharing programs in an effort to solve last-mile transportation while engaging citizens through a fun and interactive carbon credit system.

Wuhan rolled out one of the world’s largest bike-sharing projects, installing 20,000 bikes at 856 stations since 2015. Plans call for 80,000 bicycles and 3,160 stations to be installed city-wide by 2018. The new system is integrated with other modes of public transport in the city to increase connectivity. As a bonus feature, the stations offer charging facilities for electric vehicles, to further promote green transportation. Daily rides have risen from more than 1,000 during the trial period to about 80,000 in May 2016, amounting to 15 million total rides since launching.


A unique component of the system is the integration of a carbon credit scheme, through which bike-sharing users’ individual CO2 reduction is calculated based on average riding speed and other factors, and converted into a carbon credit, registered to individual users. The credit can be used to purchase small personal commodities and services, such as movie tickets, or used to offset out other carbon emissions.

Wuhan new ride-sharing program allows riders to see how much reduction to emissions they have helped after each ride.
The carbon credit concept enables citizens to know about their individual contribution to carbon emission reduction with every ride.

The Challenge

Faced with problems of air pollution and traffic congestion, Wuhan, one of the most populous cities in the Central PRC, launched an ambitious bike-shar- ing project that helps curb growing motor vehicle dependence and related emissions, while also solving last-mile transportation and boosting citizen engagement through the carbon credit system.


Economic As the first hour of bike use is free, and most bike trips last less than one hour, users are able to save money on transport.

Environment Annual CO2 emissions reduced by the bike-share system have reached 25,000 tons.

Health The bike-sharing program addresses health problems related to vehicle emissions and encourages the population to participate in a daily fitness activity.
