This study proposes an indicator-based CCIA follow-up for urban development that verifies ZEB and renewables and uses integrated data in PEIS to quantify GHG emissions and CO2 removals.
Since Sep 2022, South Korea mandates Climate Change Impact Assessment (CCIA) for major plans/projects, yet post-approval follow-up remains limited. We review seven urban development CCIA reports, classify greenhouse gas (GHG) mitigation by construction and operation, specify compliance checks, and propose an indicator-based scheme. Post-environmental-impact survey (PEIS) plans vary because boundaries between oversight and survey scope are blurred; we recommend demarcation. Construction measures: idling control, low-emission machinery, certified low-carbon materials, waste recycling. To avoid duplication with environmental impact assessment (EIA) air quality mitigation, prioritize certificates. Operation measures: on-site photovoltaics (PV), zero-energy buildings (ZEB), efficiency upgrades, and green infrastructure. As EIA omits GHG under CCIA, rigorous follow-up is essential. Key checks: ZEB compliance; for non-ZEBs, renewables or efficiency upgrades; and delivery of green/park plans, evidenced by permits, completion tests, performance tests, and field/drone surveys. For PEIS, we quantify operational GHG emissions and carbon dioxide (CO2) removals by sinks from public and utility records (electricity, gas, district heating), traffic data, and municipal open data. Where building energy management systems (BEMS) exist, end-use loads and on-site generation enable verification. Anthropogenic CO2 removals on managed land-urban trees and green infrastructure-are estimated using national factors, including annual biomass uptake per crown area.
