Climate change and its resulting uncertainties challenge the concepts, procedures, and scope of conventional approaches to planning, creating a need to rethink and revise current planning methods. This paper proposes a new conceptual framework for assessing city plans based on the idea of sustainability and planning countering climate change. It applies this framework to assess the recent master plan for the city of New York City: PlaNYC<i> 2030</i>. The framework consists of eight concepts that were identified through conceptual analyses of the planning and interdisciplinary literature on sustainability and climate change. Using the proposed conceptual framework to evaluate PlaNYC<i> 2030</i> reveals some of the merits of the Plan. PlaNYC<i> </i>promotes greater compactness and density, enhanced mixed land use, sustainable transportation, greening, and renewal and utilization of underused land. With regard to the concept of uncertainty, it addresses future uncertainties related to climate change with institutional measures only. From the perspective of ecological economics, the Plan creates a number of mechanisms to promote its climate change goals and to create a cleaner environment for economic investment. It offers an ambitious vision of reducing emissions by 30% and creating a “greener, greater New York,” and links this vision with the international agenda for climate change. On the other hand, the assessment reveals that PlaNYC did not make a radical shift toward planning for climate change and adaptation. It inadequately addresses social planning issues that are crucial to New York City. NYC is “socially differentiated” in terms of the capacity of communities to meet climate change uncertainties, and the Plan fails to address the issues facing vulnerable communities due to climate change. The Plan calls for an integrative approach to climate change on the institutional level, but it fails to effectively integrate civil society, communities, and grassroots organizations into the process. The lack of a systematic procedure for public participation throughout the city’s neighborhoods and among different social groupings and other stakeholders is a critical shortcoming, particularly during the current age of climate change uncertainty. Practically, the proposed conceptual framework of evaluate appears to be an effective and constructive means of illuminating the Plan’s strengths and weaknesses, and appears to be an easy-to-grasp evaluation method, and should be easily understood and applied by scholars, practitioners and policy makers.
