20∗20∗60: A multilevel climate change analysis framework

Cities worldwide have established plans and policies to achieve climate-neutral and climate-resilient objectives in recent decades. Researches have demonstrated that Climate Change Action Plans generally fail to include mitigation and adaptation approaches in their planning processes, despite their importance. A proposed multilevel assessment of Climate Change Action Plans, urban regeneration, and building projects was used to analyze the ten cities most sustainable in terms of developing environmental strategies, including local climate action to determine the degree of adaptation and mitigation integration in cutting-edge contexts and to identify measures that show synergies and co-benefits for urban design practices. Climate Change Action Plans, urban regeneration and building projects have been evaluated through scoring methods to determine firstly the level of integration among adaptation and mitigation and secondly the most used urban design solutions that addresses both approaches. Almost all of Climate Change Action Plans have "moderate" and "early" integration, with the most advanced in North American cities including Toronto, Montreal, New York, and San Francisco. Climate Change Action Plans partly influence urban regeneration projects. Among the cities studied, Royal Seaport and Hammarby Sjöstad in Stockholm stand out as the most advanced in terms of including measures for both mitigating and adapting to climate change, as well as the extent of activities carried out. North American building projects have the highest adaptation and mitigation strategies. Climate Change Action Plans, urban regeneration initiatives, and building projects analyzed have displayed measures to include both climate change mitigation and climate change adaptation benefits into urban design.
