There are many different definitions of sustainable development. One of the most common definitions is from Our Common Future (1987). It refers to sustainable development as the type of development that 'meets the needs of the present, without compromising the ability of future generations to meet their own needs'. The goal of sustainable development is to strike a balance between the needs of the environment, society and economy in order to maintain a decent standard of life for both present and future generations.
