Environmental Sustainability Assessment Based on the Concept of Carbon Carrying Capacity
Most of sustainability assessment tools for urban development planning do not provide any quantitative framework in terms of measuring the conceptual idea of “Carbon-neutral”. These tools generally use the scoring methodology by sum up points in various check lists for environmental sustainability. For planners, assessment of environmental sustainability should offer a simple and quantitative framework for measuring environmental resource uses and loads in order to develop planning alternatives under the limited natural conditions. The concept of carrying capacity needs to be understood as maximum loads to a limited environment, and the balance of CO2 emissions, uptakes, and offsetting acts as the most important quantitative indicators assessing environmental sustainability in terms of the conceptual idea of “Carbon-neutral”. Therefore, the purpose of this research is to investigate theories of the concept of “Carbon Carrying Capacity”, and to propose an assessment tool for measuring environmental sustainability based on the concept of Carbon Carrying Capacity. To present case study results, a high-density and mixed-use development project was chosen located in Kwangmyung-si near Seoul. Results indicated the baseline of Carbon Carrying Capacity was estimated at 0.48tCO2/capita•yr and possibilities of achieving environmental sustainability by the development planning alternatives.
