摘要公共自行车作为一种绿色出行方式，在减少排放方面具有积极意义。基于生命周期理论，我们计算了公共自行车在整个生命周期内产生和减少的碳排放量，计算表明，当公共自行车日均周转率为1.874次/辆，日均行驶距离为2.150公里，损坏率每月增加2.5%时，每辆公共自行车大约需要7个月的时间才能达到碳平衡。在碳排放达到平衡后，使用公共自行车会导致碳排放的净减少。然而，在使用公共自行车约29个月后，碳排放量再次超过减排量。在此基础上，对温岭市186个公共自行车站点的碳平衡进行了研究，并提出了政策建议，以帮助公共自行车实现真实的减排。
ABSTRACT As a green travel mode, public bikes have positive implications in terms of reducing emissions. Based on the life cycle theory, we calculate the carbon emissions generated and reduced over the entire life cycle of public bikes.The calculation shows that when the average daily turnover rate of public bikes is 1.874 times/ bike, the average daily travel distance is 2.150 km, and the damage rate increases by 2.5% per month, each public bike needs approximately 7 months to reach the carbon balance. After the carbon emission balance is reached, the use of public bikes causes a net reduction in carbon emissions. However, the carbon emissions once again exceed the emission reductions after approximately 29 months of using public bikes. Furthermore, the carbon balance of the 186 stations used in Wenling City is studied.Based on the conclusions obtained, some policy recommendations are made to help public bikes achieve real emissions reduction.
