Sustainable Consumption and Production is one of the actions called for by the Johannesburg Plan of Implementation, agreed at the World Summit on Sustainable Development in 2002 in Johannesburg. Sustainable development of emerging technologies is part of the Sustainable Consumption and Production (SCP) paradigm which is indispensable for the well-being and survival of humanity. This book contributes to the scarce literature on life cycle environmental impacts of nanotechnology and advances our understanding of the connection between sustainability and nanotechnology by taking cadmium selenide quantum dots, quantum dot photovoltaic modules and light emitting diodes as case studies and uncovering their multifaceted environmental aspects through the application of life cycle assessment tools and techniques. The book should be especially useful to professionals who work in the areas of sustainability and nanotechnology.
