Battery-powered electric cars (BEVs) play a key role in future mobility scenarios. However, little is known about the environmental impacts of the production, use and disposal of the lithium ion (Li-ion) battery. This makes it difficult to compare the environmental impacts of BEVs with those of internal combustion engine cars (ICEVs). Consequently, a(More)
River ecosystems are increasingly viewed as dynamic riverscapes; their extent, composition, and configuration vary in response to the pulsing of discharge. Although compositional and configurational shifts in riverscapes are thought to control ecosystem processes and biodiversity, attempts to quantify riverscape dynamics of braided rivers are scarce. We(More)

Relevant biomass resources were selected based on expert interviews and literature analyses. A definition of technical and sustainable biomass(More)
Today almost half of the world's population lives in urban areas, and the prospect is that 60% of the world's population will be urban by 2030 (UN, 2006). Most of this urban growth will take place in developing countries and the number of megacities will increase to 100 by 2025 (Wang and Quattrochi, 2007). One of the many problems resulting from this rapid(More)
Information technology (IT) is continuously making astounding progress in technical efficiency. The time, space, material and energy needed to provide a unit of IT service have decreased by three orders of magnitude since the first personal computer (PC) was sold. However, it seems difficult for society to translate IT's efficiency progress into progress in(More)
In the context of energy security, rural development and climate change, India actively promotes the cultivation of Jatropha curcas, a biodiesel feedstock which has been identified as suitable for achieving the Indian target of 20% biofuel blending by 2017. In this paper, we present results concerning the range of environmental impacts of different Jatropha(More)
The optimal use of forest energy wood, industrial wood residues, waste wood, agricultural residues, animal manure, biowaste, and sewage sludge in 2010 and 2030 was assessed for Europe. An energy system model was developed comprising 13 principal fossil technologies for the production of heat, electricity, and transport and 173 bioenergy conversion routes.(More)
This paper presents a water quality study performed on five small domestic ponds and one bayou of the Ganga river in the State of West Bengal, India. The concept of eutrophication is used to describe water quality by using chlorophyll as an indicator for the presence of algae in the water. During a field campaign in May 2003, reflectance spectra were(More)
The paper deals with the conception and technical development of the " Sustainability Quick Check for Biofuels " (hereafter SQCB). The SQCB is a tool to evaluate the impacts of biofuel production on environment. Against the background of mineral oil tax remission in Switzer-land providers or dealers of energy crops or biofuels in developing countries can do(More)
