An emergy analysis for urban environmental sustainability assessment, the Island of Montreal, Canada

- The major emergy flows interacting in the Island of Montreal were identified and quantified.
- The most important emergy flows were the monetary ones and those corresponding to the building materials entering the island.
- When compared to other selected cities, available space per inhabitant was correlated to empower density.
- The findings may be used as a guide to propose a methodology for the determination of intensity of development from an environmental perspective.
