As the severity of the climate crisis increases, the importance of preparing policies to reduce carbon is also emerging. As the Korean government announced the 2050 Carbon Neutrality Declaration, the role of the local governments become critical which led the comprehensive urban plan guideline to integrate carbon neutrality policies. However, it is difficult to predict whether it can lead to a substantial carbon reduction as the evaluation measures are absent. This study established indicators to evaluate the carbon neutrality of comprehensive urban plans using weighted AHP, and evaluated 12 cities in Gyeonggi-do. As a result, the highest-rated cities were Uijeongbu city, Osan city, and Yangju city, which presented detailed execution plans overall. The highest-rated indicators among them were ‘recognition of carbon emission’, ‘city carbon emission reduction target’, and ‘plan for industrial technology and production system for carbon reduction’, while the lowest-rated indicators were ‘coordination with other institutions’, ‘mixed-use development’ and ‘making continuously monitor, evaluate and update’.
