Due to a high concentration of people and activities in cities, they are at the forefront of battle against climate change (Ayyoob Sharifi/Hiroshima University). With the world projected to be highly urbanized by 2050, cities are encouraged to take urgent climate actions to mitigate and adapt to the threats of climate change. As climate change intensifies and urbanization increases rapidly, local governments are expected now more than ever to lead climate action planning. However, studies show the limitations of the existing climate action plans (CAPs). So scientists from Hiroshima University have created an Urban Climate Action Planning (UCAP) framework to guide the development of urban CAPs and support the assessment of the level of suitability of these plans. Their work is published as a critical review in the journal Renewable and Sustainable Energy Reviews on October 22, 2023. More than half of the world's population presently resides in urban areas, and this number continues to rise. At the same time, urban areas are the most vulnerable to a changing climate and its associated challenges, including heatwaves, floods, storm surges, and other natural hazards. Cities are responsible for over 70 percent of global greenhouse gas emissions and consume more than two-thirds of the world's energy. Scientists know that it is necessary to move beyond the "business as usual" approach to achieving sustainable urban development. The importance of urban CAPs in reducing greenhouse gas emissions and adapting to the impacts of climate change is already well documented. Recent research has highlighted the need for urgent urban climate actions to drastically reduce greenhouse gas emissions and develop systems for climate adaptation. The Hiroshima University scientists noted the pressing need for a more scholarly criticism of the existing CAPs and their suitability in guiding climate adaptation and mitigation efforts.
