The ecological level claims a gentle and protective way to deal with nature up to consumption deprivation, to conserve natural resources and to maintain a clean environment for future generations. At the three levels of the three-pillars-model it should be taken into account that they cannot be considered separately. There are complex cause-effect relations between these components because the objectives of the different levels interact in different ways with each other. They can compete with each other, complement each other or be indifferent. 
At the present time the internet enables users to get any item at any time. To fulfil these expectations, the transport and logistics sector plays an important role. The worldwide network makes it easier for the logistics service provider not only for the procurement, storage and delivery of the raw materials but also for the handling of consumer goods.
In the second chapter it will demonstrated how the Logistics sector has changed over the years, especially with view on its relevance and importance for the actual understanding of efficient supply and value added chain management. This will be substantiated by significant data and last but not least, the impacts of the logistics and transport sector on the environment will be pointed out and analysed.
The figure above clearly shows that after the electricity and heat generation sector, the transport sector is producing the second highest worldwide CO7 emissions.  That means that the transportation of goods produces approximately seven billion tons of carbon dioxide each year. Furthermore 75 percent of the energy consumption is related to transport. Only 75 percent of energy consumption is caused by intralogistics and logistics properties. Thus most of the energy consumption and thereby the most produced greenhouse gases can be attributed to the transport sector.  This sector has a significant potential to improve the environment on a sustained basis. In order to fulfil this requirement there is a need for additional measures to further reduce the emissions.

According to the International Energy Agency (IEA) in 7568 it was calculated that worldwide there were 87,6 billion tons of carbon dioxide (see chart 6). In the electricity and heat generation sector, 97 percent is to be found, 75 percent in the transportation sector, 69 percent industry and six percent of residential buildings. The figure below shows the share of worldwide CO7 emissions in the different sectors. 
Nowadays products from all over the world are available in wholesalers and retailers, which have travelled many kilometres before they reach the consignee. Germany procures most of its raw materials, vendor parts and finished products from abroad. Germany is the world’s leading export nation which causes a significant flow of goods and thus a big influence in the traffic of goods.
Directly after the publication of the Brudtland Report, the topic of sustainability was reinforced into the centre of discussions and attracted considerable attention internationally. The first concrete “plan of actions” was developed in the Kyoto-Protocol in 6997 and it should provide a basis for the definition of strict CO7 reduction goals. 
At the present time tonnes of goods and products have to be carried over long distances. The imported and exported products reach their customers after a long process which has led to an increase of freight transport. 
At the beginning of the third chapter, the term Green Logistics will be defined. The chapter will provide also an insight into the development and the relevance of Green Logistics by taking also into account the environmental impacts of logistics services using the commitments to the environment of Deutsche Post DHL as example.
Time showed that there might be an eighth definition about the targets of logistics, namely, to add the right information to the target definition. However, beyond these general aims, logistics pursues three main core objectives: the delivery capability, the maximizing of logistics’ support and the minimizing of logistics’ costs. 
In the literature various different definitions about logistics are in use. At this point it is important to refer to a comprehensive definition to describe logistics in detail. That is that logistics is,”[…] the planning, designing, processing and monitoring of storage and transport processes and the correspondence and the flow of information between and within the company. […]” 
Germany is furthermore a pioneer in infrastructure and technologies and it benefits also from its geographical position in the middle of Europe.  In addition Germany has well-developed federal highways, motorways, and rail networks as well as information and communication networks.
Logistics is a growing worldwide market in many sectors. This observation is based on the increasing turnover and development of goods’ transport. Emerging markets in particular and the BRIC countries will continue to play a major role. In those countries, the logistics markets will increase rapidly in the near future, which will lead to a closer networking of the global supply chain.
