电动自行车(电动自行车)被发现提供了一个有希望的解决方案，以减少一个地区的客运系统的温室气体(GHG)影响。使用来自北美电动自行车车主调查的数据，对模式替换模型进行了调整和扩充，以考虑波特兰的情况，或考虑不同水平的电动自行车人骑行里程(PMT)模式份额的渗透率。据测算，对于15%的电动自行车PMT方式份额，汽车出行方式份额可以从84.7%降至74.8%。每天的汽车总PMT可以从2890万辆减少到2550万辆。此外，在计入电动自行车发电和诱导电动自行车出行的排放后，客运产生的二氧化碳(CO2)排放量可以减少12%。一辆电动自行车平均每年可减少225公斤二氧化碳。这些估计表明，电动自行车具有帮助城市和地区实现气候目标的潜力。此外，这项研究还可以用来支持必要的政策和计划，以促进这一新兴模式的增长，以实现碳减排影响。
Electric bicycles (e-bikes) have been found to offer a promising solution to reduce the greenhouse gas (GHG) impact of a region's passenger transportation system. Using data from a North American survey of e-bike owners, a mode replacement model was adapted and augmented to consider the case of Portland, OR for various levels of e-bike person miles traveled (PMT) mode share penetration. It was estimated that for a 15% e-bike PMT mode share, car trip mode share could be reduced from 84.7% to 74.8%. Total car PMT per day could be reduced from 28.9 million to 25.5 million. Furthermore, carbon dioxide (CO2) emissions from passenger transportation could be reduced by 12% after accounting for e-bike emissions from electricity generation and induced e-bike trips. An individual e-bike could provide an average reduction of 225 kg CO2 per year. These estimates show that e-bikes have the potential to help cities and regions achieve their climate goals. Additionally, this research can be used to support policies and programs necessary to facilitate the growth of this emerging mode to realize carbon reduction impacts.
