Implementation Strategies for Greenhouse Gas Reduction in Urban Development Projects through Climate Change Impact Assessment

Since September 2022, South Korea has mandated climate change impact assessments (CCIA) for urban development projects exceeding 1 million square meters. To achieve its 2050 carbon neutrality goal, the government encourages these projects to establish concrete greenhouse gas (GHG) reduction measures through CCIA. This study examines the evaluation and reduction strategies for GHG emissions in urban development projects using case analyses and reviews of the latest technologies, proposing effective approaches to enhance their feasibility. First, minimizing GHG emissions during the urban development planning stage is crucial. This involves strategic land use planning, such as securing green spaces and optimizing park locations. Second, promoting energy-efficient building designs and the use of renewable energy technologies, such as solar power and geothermal systems, is essential. This applies not only to public buildings but also to residential and commercial structures. Third, establishing a systematic framework to monitor and verify the implementation of GHG reduction measures proposed during CCIA is necessary. This study contributes to the development of effective GHG reduction strategies for large-scale urban projects and provides actionable frameworks to strengthen climate change mitigation efforts during urban development processes.
