Progress in Research on Net-Zero-Carbon Cities: A Literature Review and Knowledge Framework

Abstract

Through quantitative and qualitative analysis, this report conducts a thorough evaluation of the literature on the present progress in research on and the performance of net-zero-carbon cities (NZCCs). The quantitative analysis identifies ten major areas at this stage, and this analysis is followed by a systematic review of the dynamics and cutting-edge issues of research in the hot literature in this area. The systematic review reveals that the key points of NZCC transformation at this stage are research on zero-carbon buildings, urban paradigms, policies, economics, and renewable energy. Finally, based on the results of the previous analysis, to build the theoretical framework of NZCCs and combined with the sustainable development goals, future research directions are proposed, such as urban infrastructure transformation and low-carbon transportation, policy support and system reform, and digital transformation as well as coupling and balancing the relationships of various elements. In addition, cities need to develop evaluation indicators based on specific developments, and policy adaptability and flexibility are crucial for promoting cities’ efforts to achieve zero emissions. The current study provides targeted theoretical references and assistance for future policymakers and researchers, as well as advances and trends in the field of net zero carbon and associated research material from an urban viewpoint.

Social and Spatial Inequalities during COVID-19: Evidence from France and the Need for a New Sustainable Urban and Regional Development Paradigm

“…Fortunately, the COVID-19 crisis presents an unparalleled opportunity to rethink and reshape our urban systems to be more resilient, equitable, and sustainable at spatial levels. The recovery and resilience planning must also intertwine with global agendas and commitments such as the SDGs [10], the New Urban Agenda [6], and Net Carbon Zero Cities approaches [94,95], to ensure that cities can not only recover from this crisis but also be better prepared for the future. However, at social levels, "social contract" theories play a dual role: they both fuel political discourse and serve as philosophical reflections on the essence of societal life.…”

“…How can cities and regions face future pandemics, particularly those with high population densities? How can the future of cities and regions be shaped to confront health crises and epidemics effectively, to ensure human prosperity and social justice, and the transition from low to Net Zero Carbon Cities (NZCCs) by 2050 [94,95]? What is the new potential for net-zero spatial planning in the fabric of cities and regions?…”

“…These incongruent data necessitate further detailed analysis. Hence, four departments were excluded with extreme density values over 1000 inhabitants per square kilometer: Paris (75), Seine-Saint-Denis (93), Val-de-Marne (94), and Hauts de Seine (92).…”
