Life cycle assessment of greenhouse gas emission reduction through bike-sharing for sustainable cities

Bike-sharing has shown its potential to improve irrational urban transportation structures and significantly reduce greenhouse gas emissions. This paper thus established a computation model to assess the greenhouse gas emission (GGE) reduction through bike-sharing based on the life cycle assessment (LCA) theory. Data collected from Shanghai, China, is selected for a case study to demonstrate and validate the model. Results indicate that promoting bike-sharing can significantly reduce the life cycle GGE (LCGGE) in the transportation sector. Findings from this study highlight the environmental benefits of bike-sharing, which provide valuable references for improving urban transportation systems and developing sustainable cities.
