This study aims to make a theoretical consideration of the climate environment crisis and collaborative governance to overcome it. Climate crisis has emerged as a representative environmental problem that threatens the survival of mankind. In order to overcome the climate crisis, the IPCC suggested that the global average temperature increase should be suppressed within 1.5℃, and that 2050 carbon neutrality should be realized for this purpose. The international community is seeking a major transition to a decarbonized economic and social structure such as energy conversion and the Green New Deal policy. Response to the climate crisis and transition to a green society can be achieved through extensive civic participation and collaboration from various social groups. In the Chungbuk region, various practical collaboration activities have been carried out to realize carbon neutrality. In this study, implications were derived by collecting five cases of systematic practical collaboration activities promoted in Chungbuk and comparing and analyzing the evaluation results. Based on this, the direction of the carbon neutral policy in Chungbuk and the establishment of a practical collaboration system for realizing carbon neutrality were proposed.
