It is the development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable development ties together concern for the carrying capacity of natural systems with the social challenges facing humanity.
Examples of sustainable development:
Sustainable cities
A sustainable city considers the natural environment in its design and aims to reduce the input of energy, water and other resources, as well as minimising the generation of waste and other environmental disturbances. Vitoria-Gasteiz in Spain is one example of a sustainable city or eco-city. It has implemented a policy of mixed land use and high density development along its major transport routes. An upgraded public transport system allows more residents to live there, while remaining green belts still provide habitat for wildlife and recreational areas for people.
Eco-industrial parks
Eco-industrial parks are areas where industries are placed together to co-operatively manage the use of resources and environmental impacts caused by their operations. By sharing resources they improve efficiency and create less waste. An eco-industrial park in Kalundborg, Denmark has a number of businesses that utilise the by-products of other manufacturers. The waste created by a power station in the park is used to make cement by another firm. Other businesses use heat generated by the power plant and cement factory for some of their processes.
Corporation
Corporations are also recognising the importance of incorporating sustainable development principles into their operations. In America, Interface Inc., a major carpet tile producer has greatly improved its ecological footprint. By using recycled and more environmentally friendly products, and more efficient manufacturing processes, they have reduced their energy and water consumption. The levels of waste, particularly hazardous waste have...
