This study proposes a feedback framework linking CCIA, follow-up monitoring, and PSS to improve assessment reliability and support evidence-based, carbon-neutral urban planning.
Statutory requirements for Climate Change Impact Assessment (CCIA) came into force in Korea in 2022, requiring major development projects to assess both greenhouse gas (GHG) mitigation and climate change adaptation. While adaptation assessments primarily use existing climate projections and risk information, mitigation assessments estimate project-specific GHG emissions and identify mitigation measures based on project characteristics. However, the resulting information is not systematically accumulated, validated, or integrated into later assessment and planning processes. Focusing on the mitigation component of CCIA for urban development projects, this study proposes a data-feedback framework linking standardized assessment-stage information with follow-up monitoring and planning support system (PSS) applications. Within this framework, PSS can support verification of assessment assumptions and mitigation performance during follow-up, while observed outcomes can be fed back into future CCIA processes to improve assessment reliability. In turn, information needs and verification requirements identified through CCIA can inform improvements in PSS data structures and functions, thereby enhancing the applicability of PSS to both CCIA and climate-responsive urban planning. This iterative linkage among assessment, monitoring, and planning support can transform project-specific CCIA data into a cumulative urban climate evidence base, supporting consistent assessment practice, evidence-based planning, and carbon-neutral urban development.
