Something is sustainable if it has the optimal balance between social, environmental and economic (SEE) dimensions across its entire Life cycle. This can be expressed simply as SEE-Life.
Social, Environmental and Economic (SEE) sustainability is sometimes referred to as People Planet Profit or the Triple Bottom Line (TBL). Environmental sustainability may also be referred to as ecological sustainability.
