Description
In response to the escalating urban ecological challenges induced by global climate change, the pursuit of sustainable development and green low-carbon regenerations under the goals of peaking and neutralizing carbon emissions (dual carbon) has emerged as a pivotal approach to bolster urban resilience and enhance urban ecology. However, systematic research on the integration of urban regeneration and green low-carbon technology remains nascent. This study scrutinized the practices of urban regeneration and planning within the dual carbon framework across three distinct spatial scales: urban zones intimately tied to residents' daily lives (encompassing public spaces and residential areas), cities, and metropolitan regions. Through an exhaustive analysis of the planning, technical, and implementation systems, this study distilled the strategies of green low-carbon regeneration planning at diverse spatial scales and management orientations. It is noteworthy that while western nations advance towards green and low-carbon urban landscapes, their urbanization processes are approaching completion. Therefore, extant research and practice predominantly focus on the technical aspects of communities and buildings, with limited instances of comprehensive planning for green low-carbon development across varied spatial scales. To this end, this study compared green low-carbon regeneration and planning construction cases from United States, the United Kingdom, Germany, South Korea, Japan, and China. The findings indicate that: (1) In terms of the planning system, a balance should be struck at the metropolitan scale between performance distribution and efficient development across various cities. Concurrently, at the city level, structural carbon reduction should be pursued via spatial planning. The urban area scale should align with statutory plans or internationally recognized indicators to flexibly implement carbon reduction strategies. (2) In the technological system, both the metropolitan and city scales emphasize the comprehensive benefits of anthropogenic spatial utilization (encompassing industry, transportation, resources, and land use) and ecological spatial foundations (including mountains, rivers, forests, and fields), although their spatial measurement ranges differ. Additionally, the city scale should consider systematic planning of green spaces and wind-thermal corridors, while the urban area scale should prioritize microclimate enhancement and the large-scale application of green building technologies. (3) Regarding the implementation system, the metropolitan scale can conduct specialized research through an expert committee composed of relevant departments, government agencies, and renowned scholars, integrating research outcomes into the urban scale's regeneration planning. The city scale should develop systematic green low-carbon urban regeneration plans specifically for regeneration areas, ensuring that the planning guides all constituent systems while developing replicable and scalable operational frameworks and procedures. At the urban area scale, public participation should be encouraged, leveraging the organizational power of various government departments and neighborhood committees to involve residents as key participants in green regeneration efforts, while also considering the inclusion of social capital in funding. These findings aim to illuminate the crucial role of spatial planning in fostering urban sustainable development, providing theoretical insights that promote balanced and reciprocally beneficial growth across social, economic, and environmental dimensions.
