Abstract | Electric mobility has the potential to spearhead transport decarbonisation. While there is a vast literature on the potential benefits of electric vehicles (EVs) towards sustainability and national policies of EV adoption, regional and local polices are often overlooked. Hence, this paper aims to capture lessons learned from two bay areas, namely the Guangdong-Hong Kong-Macau Greater Bay Area (GBA) in China and the San Francisco Bay Area (SFBA) in the United States. These two regions are pioneers in electric mobility within the two largest economies of the world. An integrative methodology of transport decarbonisation and backcasting analysis are applied to analyse the progress achieved so far (2000–2018) and to project future carbon reduction potentials (2019–2050). Regional and local transport CO2 emissions are estimated by a distance-based approach. The results illustrate that electric mobility has led to carbon reductions of 1.73 Mt CO2 and 0.25 Mt CO2 in 2018 in GBA and SFBA respectively, contributing to a relative decoupling status in both regions (e = 0.85 & e = 0.14). Intra-regional variability in decoupling status is observed, with stronger spatial variations in GBA. The backcasting analysis suggests that the EV share needs to reach almost 100% before 2035 so that the 450 Delayed Action vision can be achieved. This requires a proactive policy package of cleaner electricity with emissions performance standards, EV sales mandates, expanded public charging infrastructure, and a range of measures to incentivize EV market uptakes. Major driving forces of decoupling, including vehicle kilometre travelled, public transport share, and regional/local EV policies, are also identified and discussed. |
