Eco-Efficiency Indicators for Urban Transport

This paper focuses on urban passenger transport eco-efficiency, which can be defined as the production of maximum benefits to society while minimising environmental impacts from urban transport’s inputs of energy and materials. Researchers have intensively studied transport’s varied environmental impacts, particularly through Life Cycle Assessment; this paper argues that primary transport energ...

The efficiency and eco-efficiency of manufacturing

In this paper, we review the efficiency of both manufacturing processes and systems over recent decades and compare nano-materials technologies in this context. To a first approximation, nano-materials processes appear to be about as efficient as semi-conductor processes. That is, their second law efficiencies are of the order 10, while conventional processes are of order 10. However, many of t...

Development of Eco-Efficiency Index by Emergy Analysis

The world is now facing difficulties such as climate change, energy consumption and economic crisis and the green growth is commonly used as a solution to overcome that difficulties. To achieve the green growth eco-efficiency is a very important key. Studies on eco-efficiency have been done by others using financial value of product which cannot show the real value of the product. In this study...
