| Abstract |
This study examines the feasibility of applying a greenhouse gas (GHG) emissions cap management system to the apartment sector in
Gwangju Metropolitan City, South Korea. The residential sector accounts for 21.1 percent of the city’s total emissions, with apartments
contributing 72.2 percent of residential emissions. An analysis of 734 apartment complexes with 100 or more units shows that emission
intensity is asymmetrically distributed rather than centered around a single representative value. When the building sector reduction targets
from the Carbon Neutrality and Green Growth Master Plan are applied to individual complexes using a uniform emission intensity
benchmark, the share of complexes exceeding the target rises steadily as reduction goals become more stringent, increasing from 77.7 percent
in 2026 to 99.3 percent by 2045. This pattern reflects the structural characteristics of the baseline emission intensity distribution combined
with the application of uniform criteria, rather than indicating management failure at the complex level. The findings suggest that a cap
management system for apartments is better understood as a framework that defines the structural scope requiring sector-wide mitigation
efforts, rather than as a tool for identifying high-emission outliers. The study highlights the need for differentiated management strategies that
account for variation among complexes and for integrating emission intensity targets with complementary policy measures. |
