Sustainability has become a popular term in recent times and not just in relation to maintaining and preserving the earth's natural resources such as water or trees or the air. Sustainability is now applied to all individual and collective efforts made by people (in commercial organisations, local councils, cities, government departments and charitable entities etc) to preserve energy and natural resources at every possible level. This brief booklet will look briefly at how organisations in particular can pursue an environmentally friendly and sustainable approach in the future and one that is considered to be responsible or 'green'.
