Développement durablevignette|Diagramme de Venn du développement durable, à l'intersection de trois préoccupations, dites « les trois piliers du développement durable ».Les descriptions des intersections partielles peuvent varier. Le développement durable (, parfois traduit par développement soutenable) est une conception du développement qui s'inscrit dans une perspective de long terme et en intégrant les contraintes environnementales et sociales à l'économie.
Zero-carbon cityA zero-carbon city is a goal of city planners that can be variously defined. In a narrower sense of energy production and use, a zero-carbon city is one that generates as much or more carbon-free sustainable energy as it uses. In a broader sense of managing greenhouse gas emissions, a zero-carbon city is one that reduces its carbon footprint to a minimum (ideally 0 or negative) by using renewable energy sources; reducing all types of carbon emissions through efficient urban design, technology use and lifestyle changes; and balancing any remaining emissions through carbon sequestration.
Sustainability measurementSustainability measurement is a set of frameworks or indicators to measure how sustainable something is. This includes processes, products, services and businesses. Sustainability is difficult to quantify. It may even be impossible to measure. To measure sustainability, the indicators consider environmental, social and economic domains. The metrics are still evolving. They include indicators, benchmarks and audits. They include sustainability standards and certification systems like Fairtrade and Organic.
Urban designUrban design is an approach to the design of buildings and the spaces between them that focuses on specific design processes and outcomes. In addition to designing and shaping the physical features of towns, cities, and regional spaces, urban design considers 'bigger picture' issues of economic, social and environmental value and social design. The scope of a project can range from a local street or public space to an entire city and surrounding areas.
Environmental policyEnvironmental policy is the commitment of an organization or government to the laws, regulations, and other policy mechanisms concerning environmental issues. These issues generally include air and water pollution, waste management, ecosystem management, maintenance of biodiversity, the management of natural resources, wildlife and endangered species. For example, concerning environmental policy, the implementation of an eco-energy-oriented policy at a global level to address the issues of global warming and climate changes could be addressed.
Urban planning educationUrban planning education is a practice of teaching and learning urban theory, studies, and professional practices. The interaction between public officials, professional planners and the public involves a continuous education on planning process. Community members often serve on a city planning commission, council or board. As a result, education outreach is effectively an ongoing cycle.
Weak and strong sustainabilityAlthough related, sustainable development and sustainability are two different concepts. Weak sustainability is an idea within environmental economics which states that 'human capital' can substitute 'natural capital'. It is based upon the work of Nobel laureate Robert Solow, and John Hartwick. Contrary to weak sustainability, strong sustainability assumes that 'human capital' and 'natural capital' are complementary, but not interchangeable. This idea received more political attention as sustainable development discussions evolved in the late 1980s and early 1990s.
ÉcologismeLécologisme, ou environnementalisme, est à la fois un courant de pensée (idéologie ou philosophie) et un corpus de valeurs et de propositions, dont l'orientation de l'activité politique ou parapolitique vise au respect, à la protection, à la préservation ou à la restauration de l'environnement. Ce mouvement éco-centrique a comme projet la conservation de la nature et le « respect » des équilibres naturels.
Village urbainvignette|Le village de Saifi dans le centre-ville de Beyrouth. Le concept de village urbain dérive en droite ligne de la notion de quartier défini en tant qu’unité géographique de planification urbaine. Le concept serait apparu pour la première fois, dans les années 1960, pour décrire un quartier de Boston habité par des immigrants italiens. Un village urbain a la taille d’un quartier (agrégat de quelques îlots) et se caractérise par la mixité de son occupation des sols (résidentielle, commerciale, espaces publics.
Ville du quart d'heureLa ville du quart d'heure est le modèle d'une ville où tous les services essentiels sont à une distance d'un quart d'heure à pied ou en vélo, concept relancé sous cette dénomination en 2015 par Carlos Moreno, un urbaniste franco-colombien né en Colombie en 1959, avec l'objectif afin de réduire les transports motorisés et ainsi limiter les émissions de gaz à effet de serre. Dans le passé, d'autres architectes proposèrent des concepts similaires comme Le Corbusier mais le développement de l'automobile mit un arrêt à leurs projets.
