This thesis investigates the integration of climate neutrality within the action plans of local municipalities, focusing on the relationship between these plans and the actions proposed to achieve climate neutrality in the literature. Addressing the uncertainty surrounding the commitment of local municipalities to climate neutrality and the effectiveness of their actions, the study aims to provide insights for enhancing the efficacy of policies and strategies for climate neutrality at the local level. Through a comprehensive literature review and a case study approach focusing on İzmir Metropolitan Municipality in Turkey, the research develops a checklist for evaluating local action plans, with a particular emphasis on mitigation and adaptation measures. Utilizing this checklist, the study assesses the alignment of the İzmir Sustainable Energy and Climate Action Plan (SECAP) and the Green City Action Plan (GCAP) with climate neutrality principles. The evaluation methodology involves scoring each plan based on the presence or absence of specific actions related to climate neutrality criteria, providing both quantitative findings and qualitative insights into the plans' relationship with climate neutrality actions in the literature. This research contributes to understanding how local municipalities prioritize climate neutrality in their efforts to address climate change and offers recommendations for improving the integration of climate neutrality principles into local policies and action.
