This study aims to quantitatively estimate the environmental benefits of bike sharing. Using big data techniques, we estimate the impacts of bike sharing on energy use and carbon dioxide (CO2) and nitrogen oxide (NOX) emissions in Shanghai from a spatiotemporal perspective.

Key findings



In 2016, bike sharing in Shanghai saved 8,358 tonnes of petrol and decreased CO2 and NOX emissions by 25,240 and 64 tonnes, respectively.

‍



From a temporal perspective, there are obvious morning and evening peaks of the environmental benefits of bike sharing, and evening peaks are higher than morning peaks.

‍



From a spatial perspective, environmental benefits are much higher in more developed districts in Shanghai where population density is usually higher.
