This idea can be applied to logistics as well. In the past, logistic cost has been defined in purely monetary terms. However, as not only in the EU but also in the USA and other countries became more and more aware of environmental problems ,for instance because of climate change, air pollution, noise and accidents, environmental considerations has been taken in logistics kfield. This is how Gree
Efficiency
It is a conception that means achieving the Ecological efficiency and economic efficiency at the same time. And it means downsizing the bad impacts and upsizing the gains.
(2)Social Sustainability - Social Responsibility
(3) Economic Sustainability - the real growth in economy
Among those three of them, we will discuss about the environmental sustainability.

efficiency energy means that most energy is lost with heat loss. Additionally, in case of driving in low speed, the fuel efficiency is very low. On the other hand, enhanced energy efficiency through electronic motor and battery, enabled hybrid car to operate better even in low speed. With much higher energy efficiency, hybrid cars consume less oil, representing that hybrid car is more efficient a

어떤 장기 전략적인 결정을 하기 위해서는 믿을 만한 데이타가 필요하다. 리드 타임이 수십년이나 걸리는 장기 프로젝트인 에너지부문에는 특히 그렇다.
WEC는 ‘34년부터 세계에너지자원에 대한 독자적인 참고문헌을 3년 간격으로 발간하고 있다. ’01
