Abstract

Urban development is an important policy tool of the country to enhance economic growth.  Cities are the main source of greenhouse gas emissions.  Therefore, finding ways to reduce greenhouse gas emissions is an important issue for public policy.  This paper aims to 1) study the greenhouse gas situation trends of Nakhon Ratchasima City, 2) study and analyze the EV proliferation scenarios and the greenhouse gas reduction opportunities, 3) analyze the social returns from EV proliferation scenarios, and 4) synthesize public policies to improve the environmental quality of the city.  The research methodology used the city development committee's focus group meeting method to present the results of the analysis of the city's greenhouse gas reduction data using the simulation of the electric vehicle expansion scenario with the social return results.  The research results found that the analysis data set on the promotion of electric vehicles has significant implications for reducing greenhouse gas emissions and effectively generating social returns and can lead to joint decision-making by the city development committee as a public policy under the concept of developing the city “Korat EV City”.
