Project Overview

       The "Greenhouse Gas Reduction and Management Act" explicitly states that the national long-term reduction goal is to reduce greenhouse gas emissions to less than 50% of 2005 levels by 2050 (the "Climate Change Response Act" was promulgated on February 15, 2023, with the national long-term reduction goal revised to greenhouse gas net zero emissions by 2050). Taiwan has control objectives for five-year phases in order to achieve this goal. In the first phase, it is stipulated that national greenhouse gas emissions in 2020 will be 2% lower than in 2005; by 2025, they will be 10% lower than in 2005; and by 2030, they will be 20% lower than in 2005. The reduction targets for each phase are becoming increasingly stringent.
       The transportation sector's first phase greenhouse gas control goal is a 2% reduction compared to 2005, and the second phase goal is a 6.79% reduction. There is an urgent need to seek out and propose carbon-cutting measures that are effective.
       The total number of registered locomotives in nTaiwan will exceed 14.39 million units by December 2022. Registered fuel locomotives account for 13.76 million of them, indicating that fuel locomotives account for the vast majority of registered locomotives in Taiwan. Various shared modes are still expanding as a result of the rapid advancement of information and communication technology in recent years. Rather than ownership, the emphasis is on obtaining the right to use vehicles. The topics covered in this plan are centered on shared electric vehicles (EV) and gaining a deeper understanding of their impact on changing road users' mode choices, as well as the positive and negative effects on transportation greenhouse gas emissions. They serve as a reference for local competent authorities when revising emission control and implementation plans in accordance with their authority and responsibility when managing shared modes.
Research Results

1.  With a focus on people over the age of 18 from "Taipei City" and "Kaohsiung City," a questionnaire survey was distributed via residence phones and mobile phones (1,068 copies via residence phones and 200 copies via mobile phones, for a total of 1,268 copies). The experiences of using shared electric locomotives, the characteristics of potential users and users with no intention, potential mode choice (transfer) inclinations, the intention of use, and impediments were all investigated.

• The following factors influence the willingness of both experienced and potential users: "highly mobile, convenient, and fast;" The following factors contribute to users' unwillingness: "used to driving one's own car/motorbike" and "inconvenient."

• Among experienced users who can accept access to shared electric locomotives within five minutes (about 300 meters), Taipei City accounts for approximately 70% and Kaohsiung City accounts for approximately 90%; among potential users who can accept access to shared electric locomotives within three minutes (about 200 meters), Taipei City accounts for approximately 90% and Kaohsiung City accounts for approximately 80%.

2. According to estimates, the use of shared electric locomotives reduces carbon emissions. Those from Taipei City with shared electric locomotive use experience can save 111-131grams of CO₂e on average after each use, while those from Kaohsiung City can save 177-185grams of CO₂e on average after each use. 

 Result Promotion and Benefits

1. “Shared electric locomotives have cut down more carbon during the COVID-19 pandemic?” has been completed.
2. Experts and scholars, local transportation bureaus, and shared electric locomotive operators were invited to exchange ideas in November 2022 on vehicle access time (distance) accepted by the general public, whether people will buy/sell/declare scrap privately-owned locomotives after riding shared electric local motives, shared electric locomotive positioning (public transportation competition), and other issues. These concepts may be used by local governments in the future during policy administration.
