The rapid growth and development of the city has been experienced by various regions, one of which is Samarinda City, which is the capital of East Kalimantan Province. As a result of the development of Samarinda City, causing environmental problems accompanied by other negative impacts. To deal with and solve these problems, the method determined by the Samarinda City government is by implementing the green city concept. One of them is the development of green open space as an indicator of the green city concept. Through observation, interviews and documentation, the results of the research were (1) only about 10% of Samarinda City’s green open spaces, (2) the constraints faced were limited land, insufficient budget, land acquisition, violations of provisions on land and building use, lack of coordination between implementers of RTH providers, as well as the lack of compliance and understanding of the public regarding green open spaces, (3) The strategy implemented by the Samarinda City Government in implementing the green city concept is, providing green open space through the ProBebaya program, increasing community compliance and implementing private green open space regulations, providing sanctions, and socialization of the importance of green open space.

There are many concepts and methods trying to accommodate the growth of cities without impairing sustainability. However, most are too complex, cannot measure green performance over time and fail to deliver actionable advice to decision-makers. The Green City Concept (GCC) is one of the latest of these concepts. This paper introduces a Green City Conceptual Framework (IHS-GCCF) and a harmonized method to measure Global Green City Performance over time (GGCPI). The IHS-GCCF highlights the importance of energy as a steward of resource efficiency and green performance. IHS-GCCF and GGCPI can be used to measure green performance, to explain possible factors influencing the calculated green performances over time, set targets and track achievements. They are adaptable to individual city needs. By applying the method to fifty cities worldwide through desk research, the paper shows that a green city is also sustainable and liveable. It also shows that GDP influences Green City Performances positively, population size influences it negatively and sanitation and air quality sectors influence green city performance the most. The paper addresses a range of gaps in the green city field. It consolidates prior research into one actionable conceptual framework and method.

With the progress of urbanization, the living rhythm of urban residents has become faster and more stressful. The role of the natural environment in relieving the stress of urban residents has become more important in cities. As urban green space (UGS) is the most accessible natural environment for urban residents, the rationality and equity of its distribution are particularly emphasized nowadays. In this research, Xiamen had been used as an example to analyze the relationship between the level of urbanization and the equity of UGS services. This research found: (1) polarization in urbanization of the inner city and outer city, and inequity in the distribution of urban green spaces in Xiamen. (2) The urbanization level and distribution of UGS demonstrated a radial mode that gradually shrinks from inner city to outer city. (3) This research found a significant positive correlation between urbanization and UGS provision, and spatial heterogeneity in the spatial relationship between them. In order to coordinate future urban development and the planning of UGS service, this research suggests increased investment in infrastructure construction in outer city, and the government should consider a policy to encourage the population transfer from inner city to outer city, through the balancing of urbanization level and UGS service equity between inner and outer city to build a harmonious and sustainable green city.

The development of projects for new eco-cities is rapidly becoming a global phenomenon. Alleged eco-cities are being built across a variety of spaces via processes of urbanisation triggering substantial environmental, social and economic impacts. This article investigates how new eco-city projects interpret and practice urban sustainability by focusing on the policy context that underpins their development. The article argues that projects for new eco-cities are shaped in loci by policy agendas tailored around specific economic and political targets. In these terms, the ideas and strategies of urban sustainability adopted by eco-city developers are understood as reflections of broader policy priorities. The case study employed in this article, Masdar City, reveals how the Emirati eco-city initiative is the product of local agendas seeking economic growth via urbanisation to preserve the political institutions of Abu Dhabi. Following the economic imperatives set by the ruling class, the Masdar City project interprets sustainability as ecological modernisation and practices urban environmentalism almost exclusively in economic terms. The article shows how the developers of Masdar City capitalise on sustainability by building an urban platform to develop and commercialise clean-tech products, and concludes that the Emirati alleged eco-city is an example of urban eco-modernisation: a high-tech urban development informed by market analysis rather than ecological studies.

More and more cities around the world are adopting green-city labels and are making use of their urban environmental policymaking for the purpose of place branding. However, the nature of the relationship between the branding of green cities and urban environmental policymaking is contested. Some researchers have highlighted so-called ‘greenwashing’ and the cherry-picking of easily attained goals. Others argue that green branding is driven by altruism, rather than intra-urban competition and entrepreneurialism. Drawing on literatures on policy tourism and green place branding, this article presents a longitudinal study of green branding in Växjö, Sweden. It contributes to the debate on green place branding by showing how two sets of contradictory impulses – entrepreneurialism/competition versus altruism/cooperation, and cherry-picking/greenwashing versus comprehensive environmental policymaking – affect the relationship between green place branding and environmental policy. In particular, the analysis illuminates the changing role played by policy tourism in shaping both the development of environmental policies and branding practices. 世界上越来越多的城市正在采用绿色城市标签，并正在利用其城市环境决策来打造地方品牌。但是，绿色城市品牌与城市环境决策之间关系的本质是有争议的。一些研宄人员己经强调了所谓的 “绿色包装” 和挑容易实现的目标 “采摘櫻桃” 的问题。还有的人认为，打造绿色品牌是由利他主义推动的，而不是城市内部的竞争和创业精神。本文利用关于政策性旅游和绿色地方品牌打造的文献，报告了关于瑞典韦克舍绿色品牌打造的一项纵向研宄。通过展示两套相互矛盾的冲动一一创业精神/竞争对比利他主义/合作，以及“采摘櫻桃” / “绿色包装”对比综合环境决策一一如何影响绿色地方品牌与环境政策之间的关系，本文对关于绿色地方品牌打造的讨论作出了贡献。我们的分析尤其说明了政策性旅游在塑造环境政策和品牌打造实践中所发挥作用的变化。

Sustainable urban development has become a central reference in planning discourses. However, this ideal unfolds within a complex web of tensions as well as various economic, social, and environmental challenges. It is a process that calls for coherent and adaptive policies and frameworks capable of addressing a range of issues from managing urban expansion and congestion to fostering competitiveness, innovation, social inclusion, and environmental sustainability. In this context, cities are no longer considered as passive recipients of global agendas or crises, but as the standing ground of innovation where models of governance are tested and negotiated.This paper examines the case of the Green City of Benguerir in Morocco, where sustainable urban development is implemented within overlapping local, national, and global scales. Through the combination of a conceptual discussion of multi-scalar governance with an empirical analysis of the city’s development trajectory, we aim to emphasize how actors at different levels interact in shaping the outcomes of urban sustainability.The findings highlight the critical role of coordinated, context-sensitive, and adaptive governance in moving beyond greenwashing and branding. Rather than considering the Green City of Benguerir as a model to replicate, the case study exposes how multi-scalar dynamics can either strengthen or challenge urban sustainability claims, offering insights for other cities across the Mediterranean that are facing similar tensions.

Ecological urbanism is seen today as one of the keys towards unlocking the quest for a low-carbon or fossil fuel–free society. Global and local policies promote and advocate the eco–city as the most environmentally sound model of sustainable urbanism. It is argued that the eco–city strategies and solutions are expected to deliver positive outcomes in terms of minimal demand on energy resources and thus minimal environmental impacts. Moreover, it has recently been suggested that the eco-city needs to embrace and leverage what advanced ICT has to offer, particularly with regard to sustainable energy systems, so as to improve and advance its contribution to the goals of environmental sustainability. This paper examines how the eco–city especially its core environmental dimension is practiced and justified in urban planning and development with respect to sustainable energy systems and their integration with data-driven smart technologies at the district level. To illuminate this urban phenomenon accordingly, a descriptive case study is adopted as a qualitative research methodology where the empirical basis is formed by urban planning and development documents combined with secondary data and scientific literature. To provide a theoretical foundation and produce a rationale for this study, this paper first provides a state–of–the–art review of the field of ecological urbanism in terms of its foundations, models, strategies, research issues, as well as data–driven smart technological trends. This study shows that the Eco-city District of Stockholm Royal Seaport uses green energy and data-driven smart technologies as the key strategies and solutions for achieving the environmental objectives of sustainable development in terms of lowering energy consumption and mitigating pollution. This entails conserving and decreasing the demand for energy through renewable resources (i.e., sun, wind, and water), bio–fuelled Combined Heat Power system, large-scale smart grid system, energy management, sustainable waste management, and passive solar houses. This research enhances the scholarly community’s current understanding of the emerging phenomenon of the smart eco-city with respect to the synergic potential of the integration of its sustainable energy strategies with data-driven technology solutions for advancing environmental sustainability.

Authors aim to carry out a bibliographic review as an initial approach to state of the art related to the quality of urban soils, as well as its possible link with human health. This concern arises from the need to highlight the consequences that soil could face, derived from the growth and aging of the population, as well as its predicted preference for urban settlement. Urban development may pose a challenge to the health of urban soils, due to degradative processes that it entails, such as land take, sealing, contamination or compaction. A healthy soil is the one which maintains the capacity to support ecosystem services, so it can provide numerous benefits to human health and well-being (carbon sequestration, protection against flooding, retention and immobilization of pollutants and a growth media for vegetation and food production). This article addresses threats facing urban soils, the strategies put forward by the European Union to deal with them, as well as the issues that require further attention. Greening cities could be a consensual solution, so authors analyze whether soils of cities are ready for that challenge and what resources need to maintain soil ecosystem functions. This review proposes to use made by waste Technosols for a sustainable green city. Although the use of Technosols as a type of soil is very recent, the interest of the scientific community in this field continues to grow.

Eco-cities have witnessed rapid growth in these years worldwide. As the Eco-cities entering operation stage gradually, more and more researchers have found that users (who are living or working in the Eco-cities) satisfaction is one of the most important factors to determine the success or failure of Eco-cities. Therefore, it is very important to investigate the user demands to attract more citizens willing to live or work in the Eco-cities, which will make the development of Eco-cities more sustainable and solid. The recent researches on user demands investigation and analysis in the Eco-cities mainly focused on understanding the user need itself, yet lack of research on the relationship between the user demand and user satisfaction. This paper initially introduced the Kano model analysis method to the research field of user demands in Eco-city, to explore the relationship between the user demand and user satisfaction. After proposing user demands library in Eco-city (including Land use, Ecological environment, Green building, Energy utilization, etc.), the user demands classification and importance analysis methods of Eco-city were proposed based on Kano model. The questionnaire survey for users of two Eco-cities in China as case study was conducted, consisted of user demand items questionnaire based on the Kano model and a questionnaire on the importance of the user demand items. By utilizing the integration of quantitative analysis methods based on the Kano model and Analytic Hierarchy Process (AHP) method, the final ranking of user demands importance was obtained. Comparing with the existing literatures in terms of user demands research for Eco-city, the user demands analysis method based on Kano model of this paper, is able to reveal the influence degree of user satisfaction towards the facilities and services provided in the Eco-city. The user demands analysis method can be used for other researchers worldwide to investigate and quantitively analyze user demands according to their local development situation and preference of Eco-city. The user demands analysis results obtained through this method, can benefit different stages of Eco-city.
