How much of the Earth’s productive land and freshwater resources are required to sustain us?


As the Earth becomes more resource constrained and has less capacity to assimilate wastes from increasing populations, this question is evermore critical.  We need to know, and we need to improve our ability to answer the question.


Environmental footprints are effective tools to respond to this question. Through scientifically based methodologies, Sustento assists both private and public sectors to quantitatively evaluate their environmental footprints and find ways to reduce them.
