Development of Net Zero Contribution Evaluation Items for Urban Parks

This study developed items to evaluate the Net Zero contribution of urban parks, which were suggested as additional carbon sinks for achieving the 2050 Net Zero goal, and the results of the study are as follows. First, the evaluation items that were introduced were 46 items in 9 fields selected by investigating and analyzing previous studies and related systems. Second, FGI and Delphi analyses were conducted to verify the appropriateness of the derived items, and 22 evaluation items in 10 fields were ultimately derived. Third, the results of AHP analysis to set the importance of the evaluation items showed that the planting technique was the highest among the 10 fields. In terms of the importance of each item, the green space system connection item was analyzed as the highest in the relative decision method, and the planting item of tree species with high carbon absorption was analyzed as the highest in the absolute decision method. This study differs from previous studies in that it presents items that can evaluate the Net Zero contribution of urban parks, and additionally conducts an importance analysis of each item so that it can be used to determine priorities for improving the contribution to Net Zero. In addition, the results of a comparative analysis of the relative and absolute decision methods when utilizing the AHP technique were intended to be used as a basic study for related follow-up studies.
