Bike sharing is becoming increasingly popular around the world. However, there is little empirical evidence of the emerging free-floating bike sharing (FFBS) system, and even less from a product life cycle perspective. Based on actual urban transportation big data and related product life cycle data, this chapter takes Beijing FFBS system as a study case. By comparing the changes in the choice of transportation means of urban residents before and after the emergence of FFBS, and in combination with the evolution of the FFBS system, the real environmental impact of FFBS is dynamically observed and evaluated from a life cycle analysis (LCA) perspective. The results show that FFBS display desirable properties in reducing air waste in the form of greenhouse gas (GHG) emissions. This reduction effect is mainly achieved by connecting to the public transportation system, hence substituting for the use of private cars. Yet, in comparison to the period prior to the emergence of FFBS (i.e., 2016), the excessive supply of FFBS resulted in an average annual increase of 0.38% in air waste as GHG emissions by daily transportation of urban residents in 2017 and 2018, with a cumulative increase of 0.102 million tons CO2,e. Since then, under increased government control, the scale of the FFBS system has gradually become reasonable and the operating efficiency has gradually improved. In 2019, air waste as GHG emissions were reduced by 0.065 million tons compared with 2016. Especially, according to the development plan of Beijing FFBS system, it is expected that the emission reductions will reach 0.16 million tons, a reduction rate of about 1.13%.
