Electric vehicles (EVs) are considered to be a solution for sustainable transportation. EVs can reduce fossil fuel consumption, greenhouse gas emissions, and the negative impacts of climate change and global warming, as well as help improve air quality. However, EV adoption in Thailand is quite low. Against this backdrop, this study investigates barriers and motivators for EV adoption and their public perception in Thailand. A total of 454 responses were collected through an online questionnaire. The results indicate that the top three concerns of respondents about EVs are public infrastructure and vehicle performance in terms of charge range and battery life. Respondents with more than five years of driving experience in the age range of 26–35 years old could be key targets for early EV adoption.

Global emissions from the transportation sector were nearly 7.7 GtCO₂ in 2021. In Thailand, the transportation sector emitted 69 MtCO₂ and consumed 27,460 ktoe of final energy in the same year. Transitioning from internal combustion engine vehicles (ICEVs) to electric vehicles (EVs) can help reduce greenhouse gas emissions and air pollution, particularly PM2.5, in major metropolitan areas. However, in the early stages, the adoption of EVs may affect consumer considerations. This study aimed to investigate motivators and environmental awareness regarding EV adoption in Thailand. It also analyzed CO₂ emissions from the transportation sector in Thailand, covering the period from 1987 to 2023, to understand long-term trends and recent changes. An online questionnaire was conducted, and a total of 459 respondents participated. The results revealed that the top three motivators for respondents to consider EVs were the potential tax refund for purchasing an EV, lower charging costs compared to fuel costs for ICEVs, and lower operating costs for EVs compared to ICEVs. In terms of environmental awareness, respondents expressed concerns about adapting to global warming, the potential for EVs to reduce air pollution, and the environment in general. Based on the findings, individuals aged between 26 and 35 years old could be the key target group for early EV adoption.

Let O_K be the ring of Integers of a Field K. By an order O in K we mean a subring of O_K containing a Q-basis for the field K. The largest ideal of OK contained in O is called the conductor of O. In this paper we investigate conductor ideals whose norm is a power of some ramified prime in quartic number fields.
