We are joined now by our reporter Liu Yang in Chengdu, the capital of southwest China's Sichuan province.

Well this certainly looks like a great way to travel around the city, tell us more about this car-sharing service.

Car-sharing is primarily designed for short trips. It's aimed at decreasing personal car ownership, reducing the distances vehicles travel and improving urban land use and developmentas well as motivating residents to walk, cycle or use public transport to get to work to reduce greenhouse gas emissions.The good thing about car-sharing is that customers can rent the vehicle twenty-four-seven as a supplement to public transport enabling them to save around two-thirds of the cost of using a taxi. For example, travelling 20 kilometers in a taxi will cost nearly 70 yuan but with the car-sharing service it's only 18 yuan.In Shanghai, one vehicle from their EVCARD program is used 10 times per day. In Chengdu, it's around 4 times per day. But there are still a number of challenges ahead before the service can grow - for example, a shortage of parking spaces is an issue in Chengdu, and another problem is how the used vehicles are handled. The EVCARD model is very similar to France's Autolib and car2go which began in Germany. Autolib is the first fully electric, open-access car sharing service in Paris. They have around 10,000 rentals every day from their 100,000-strong customer base and also boast some 6,000 parking spaces across the city where the cars can be charged.
