Recently, urbanization has become a serious issue, as there is imbalance between regions and various environmental problems occur intensively in cities. Therefore, cities all over the world are promoting the Green New Deal and trying to realize carbon neutrality. Accordingly, the European Union is leading the creation of carbon-neutral cities by promoting policies aimed at rapidly realizing carbon neutrality. In Korea, projects such as U-City and Smart City have also been promoted continuously for many years, and recently, the projects Smart Green City and Carbon Neutral Green City have been introduced. Therefore, this study aimed to derive directions and implications for future projects based on policies to address climate change by analyzing the guidelines for the Smart Green City project and the project plans of Gimhae-si and Gangjin-gun, which are the leading projects in the Smart Green City business model and are equipped with an extensive budget.

Climate change has recently become a serious global issue, and carbon emissions and energy consumption are increasing, particularly in cities where economic activities and populations are concentrated. Accordingly, various countries worldwide are promoting the Green New Deal and promoting urban-centered climate change response policies with the aim of carbon neutrality. In Korea, following the “smart green city” project that creates a city where humans and the environment coexist, a similar “carbon neutral green city” policy is set to be introduced. Therefore, in this study, implications and directions for the sustainable introduction of the carbon neutral green city policy will be derived by comparing and analyzing the State and Tribal Assistance Grants of the U.S. bipartisan infrastructure law and the smart green city of the Korean new deal.

This study was designed to identify citizens’ awareness and satisfaction of Green Roof Projects (GRPs) in Changwon City, South Korea. Changwon City implemented a “Green Roof Promotion Planning” project according to the city’s codes and regulations from 2009 to 2011. The project introduced guidelines for ecological area rates and provided financial subsidies for the green roofing of private buildings. A citizens’ survey shows that 64.8 percent of respondents have a positive awareness of GRPs and think the projects’ priority should be on public buildings and commercial/office buildings. About 43.1 percent of green roof users were satisfied with green roofing in terms of housing improvement and energy saving. However, 34.6 percent of green roof users were not satisfied with regard to plant management. Educational level made a statistically meaningful difference in terms of the awareness of the project’s needs and participatory spirit. Statistics of the survey showed that citizens’ attitude of participation spirit was influenced by the increase in value of a building, green space expansion, and ecosystem conservation. However, their satisfaction was determined by housing improvements. The results of this survey call for a deliberate policy effort on the part of Changwon City to increase the projects’awareness, satisfaction, and participation
