为什么全球公交车电动化进程正在加速

世界各地城市的公共交通机构越来越多地响应号召，通过定义和建立向可持续零排放公交车队过渡的任务，采取积极的气候行动，减少温室气体(GHG)排放.

到目前为止 世界领袖 in bus electrification is China, 世界上约98%的电动公交车在该国境内运营, including in the city of Shenzen, which boasts a municipal bus fleet of more than 16,000 vehicles.

In Europe, where centralized funding agencies are 积极支持 the development of clean bus projects, 电动公交车队遍布荷兰的各个城镇, 德国, 英国和法国. 在 亚太地区, 日本, 印度, 巴基斯坦和韩国也有重大的公共汽车电气化计划，要么已经实施，要么正在进行中.

在北美, 在过去的一两年里，变化的步伐尤其加快, 随着公共交通车队电气化计划在大城市，如 多伦多, 华盛顿特区.C. 和 西雅图, as well as many small 和 medium-sized cities such as 位于安大略省滑铁卢. 和 埃德蒙顿,阿尔塔.

The widespread growth of politically powerful voices dem和ing governments, 世界各地的机构和商业组织采取了有意义的行动来应对气候变化，这促使许多公共交通机构迅速加快其公共汽车车队电气化的计划.

The 运输 sector has been identified by the U.S. Environmental Protection Agency (EPA) as the largest contributor to greenhouse gas (GHG) emissions in the U.S., with surface 运输 such as cars, trucks 和 buses accounting for the bulk of those GHG emissions. 因此, 公共交通机构在其运输车队中采用零排放实践的切实努力通常是高知名度的公共举措，通常被积极接受为遏制人为气候变化的重要一步.

然而, 虽然电气化可以提供显著的环境和运营成本效益 traditional fossil-fueled buses, the associated capital costs to establish a new zero-emission fleet can be 障碍 transitioning to a zero-emission fleet，特别是由于 electric-charging infrastructure requirements.

The fact is, vehicle electrification technology has matured enough in recent years that it is now feasibly practical to implement a fleet-wide electrification, but many key considerations still exist. 将整个市政交通车队转换为电动汽车并不像购买新公交车来取代现有公交车那么简单.
