Research Background
As global efforts to mitigate the climate crisis intensify, the development and application of effective policy tools to achieve carbon neutrality have become increasingly critical. In South Korea, urban planning mandates the integration of carbon emission and absorption data and the monitoring of greenhouse gas (GHG) reduction targets established every five years. To support carbon-neutral urban policies, the “Carbon Spatial Map” system has been developed, providing essential data for urban planning processes.
Methodology for Developing the Carbon Spatial Map
The Carbon Spatial Map visualizes spatially disaggregated data on carbon emissions and absorption across three sectors: buildings, transportation, and carbon sinks. This information is presented at a high spatial resolution of 100-meter grid units. In contrast to traditional top-down national GHG inventory methods, the Carbon Spatial Map employs a bottom-up approach, calculating emissions based on direct sources.
- Buildings: Carbon emissions are calculated by converting electricity, gas, and district heating usage for individual buildings into emission values.
- Transportation: Emissions are estimated using traffic volume and vehicle speed data specific to road segments.
- Carbon Sinks: Carbon absorption performance is spatially assessed using forest land cover data, which is integrated into the overall map.
Applications in Urban Planning
The Carbon Spatial Map is being enhanced as a decision-support tool for urban policy formulation, including urban planning. South Korea’s urban planning guidelines stipulate that carbon-neutral elements must be incorporated into urban planning processes. To facilitate this, simulation tools are being developed to assess the carbon emission impacts of proposed urban plans. These tools utilize data from the Carbon Spatial Map to evaluate the environmental impacts of various urban development projects.
Furthermore, a monitoring module is being designed to track progress toward GHG reduction targets. This module will also quantify the contribution of carbon-neutral urban planning strategies to emission reductions.
Currently, the Carbon Spatial Map provides detailed information on carbon emissions and absorption. Future developments aim to expand the range of data provided, thereby establishing the system as a practical and scientific tool for governments and municipalities to design and implement carbon-neutral urban policies.
