Green buildings have gained increasing relevance and market share in recent decades. Also, higher education institutions are progressively incorporating the conceptualisation of sustainable development by greening campuses. Thus, given the construction sector relevance in climate change mitigation and the role universities have to play as models for society, the purpose of the present paper is twofold. First, the authors develop a baseline study to determine the extent to which green buildings' features and certifications are being incorporated in public Chilean higher education institutions, as a first of its kind effort in the higher education sector in Chile. Second, the authors explore the opportunities that can support the advancement of campus greening through green buildings deployment on university campuses in Chile. This study follows a qualitative strategy approach in the form of a survey design based on the UI GreenMetric World University Ranking that was administered through an online questionnaire to representatives who hold the position of Sustainability or Infrastructure Heads in public universities, which are united in the Chilean State Universities Consortium. The main findings suggest a general maturation process of green building features´ incorporation on campuses at Chilean public higher education institutions in early or transitional stages. The leading indicators relate to open space, pedestrian paths, and efficient appliances, whereas the reported performance is lower with respect to sustainability budget, zero emission vehicles, and greenhouse gas emission reduction programmes. The opportunities identified for promoting the implementation of green buildings relate to three entrenched dimensions: research, promotion, and public policy. [ABSTRACT FROM AUTHOR]

Why does everyone think cities can save the planet? Contemporary planning interventions promise salvation via spatial fixes that might reduce carbon emissions, boost metropolitan economies, and allow urban society to thrive in spite of rising seas and climate disasters. New wetlands, floodgates, and other adaptive infrastructures allow water to coexist with urban space; new parks, such as New York's High Line and Chicago's 606, celebrate the interweaving of built and natural environments and suggest how outmoded infrastructure can be repurposed for civic benefit. While the climate dilemmas at hand are historically new, the use of landscaped environments in the service of solving social problems is not. Dating to the first generation of urban park development in the 19th century, planners have deployed green spaces as solutions to various cultural, political, and economic conundrums of the city. Offering an historical parallel and counterweight to investigations of contemporary urban–environmental dynamics, this paper investigates the period of park development that occurred in the 19th century in North America and Europe, using Chicago's Olmsted-designed South Park (the contemporary Washington and Jackson Parks) as a case study. I argue that green spaces' distinct nexus of (1) normative cultural meanings around nature, (2) power relations bound up in dominant landscape aesthetics, and (3) direct link to the economic realm via the structuring of land values have made green space development a powerful 'cultural fix': a means of using social space to mitigate perceived social crises. Understanding the historical foundations of green spaces' use as cultural fixes can inform contemporary analyses, particularly as new landscape ideologies emerge as part of broader green urbanism development and climate change adaptation strategies.

With nearly 70% of the world population expected to live in cities by 2050, assessing the sustainability of urban systems, both existing and future ones, is becoming increasingly relevant. Making cities more sustainable is a global priority, which is highlighted by 'Sustainable Cities and Communities' being listed as one of the Sustainable Development Goals (SDG) adopted by United Nations Member States in 2015. This Virtual Special Issue (VSI) explores the implementation and assessment of policies and technologies that contribute to the transition to a sustainable, energy efficient and regenerative society. We organized the issue according to four main research themes: 1) Renewable Energy Systems (i.e., different types of systems, qualitative assessments and public acceptance); 2) Sustainable Built Environment (which includes construction, operation and refurbishment); 3) Multi-Scale Models (considering urban sustainability transition from building to districts, or cities and regions to multi-country comparisons and their scaling across different countries); and 4) Governance and Policy (climate change mitigation and adaptation plans/policies that are reported across countries, urban services and infrastructures). This paper serves two purposes. The first is to provide an analysis about patterns, correlations and synergies found across the different topics that have been addressed over the last 20 years in the literature about cities' sustainability paths. A bibliometric analysis and a contingency matrix show the degree of correlation between scientific journals and main topics addressed by published articles. Secondly, the paper acts as an Editorial to the VSI, introducing the wealth of research articles and topics included in it. Both the bibliometric analysis and the papers published in this VSI demonstrate the interconnectedness of energy consumption, pollutant emissions and the competition for finite resources. The aim is to present advances and challenges of this exciting and ever-evolving research field to inform and guide future studies of urban sustainability. • We carried out a bibliometric analysis of the literature using the Cortext Manager platform· Using network analysis of a corpus of paper spanning 20 years we identified 8 major clusters. • The paper serves also as editorial for a virtual special issue dealing with urban sustainability pathways. • The virtual special issue is organised in four main themes, which touch upon different Sustainable Development Goals.
