In 2005, Brent and Visser demonstrated an environmental performance resource impact indicator (EPRII) calculation procedure by introducing the life cycle impact assessment (LCIA) framework for comparing burdens at operational level. This journal provides a good introduction of life cycle management; however, the authors do not make holistic perspective on the aspects of sustainability in project management. This consequently enables readers to have a better understanding of the concept.All the social criteria and its sub-criteria were verified with respect to project management and business, but particular impacts were found to be more significant in certain appraised asset or technology life cycle phases.In conclusion, altho...
