Sustainability is defined as meeting the needs of present generation without compromising the ability of future generations to meet theirs. It creates a balanced condition in which human beings exist in harmony with nature ,while fulfilling their social and economic needs.
LCA principles form a core element of efforts to asses sustainability ,which allows analyst to consider parts of a system and multiple environmental indicators in developing effective policy.
This analysis can be expanded to consider economic impacts by incorporating results into either a benefit- cost analysis or by incorporating data and dynamics into LCA itself.
