Environmental quality is often a credence good and consumers are unable to distinguish between green and brown products. The paper aims to investigate the role of certification in providing information about product quality and reducing market inefficiencies when the certification process is imperfect. We consider a duopoly in a vertically differentiated product model where firms compete in qua...

The theoretical and empirical innovation literature stresses the importance of regional factors and location conditions for location choice of firms and their innovation success. Innovation activities are not equally distributed in space because agglomeration effects and specific regional infrastructures may promote innovation activities. Concerning environmentally oriented innovations, the so-...

Poor environmental performance of the manufacturing activities is said to be attributed to the pollutants produced and emitted during the manufacturing process. These pollutants are regarded as undesirable output and cannot be ignored when measuring the efficiency of manufacturing activities. By applying Data Envelopment Analysis (DEA) and Directional Distance Function (DDF) approaches, this st...

The inhabitants of the rumen microbial eco-system, a complex consortium of different microbial groups living in symbiotic relationship with the host, act synergistically for the bioconversion of lignocellulosic feeds into volatile fatty acids which serve as a source of energy for the animals. The constraints, imposed by the host and the feed consumed by the animal, under which these microbes ha...

Eco friendly pharmaceutical packaging materials are the safe materials for environment which enclose pharmaceutical product in any of the dosage forms. They may be derived from natural resources, like starches, proteins etc. that inflict little or nearly no harm on the environment and the environment dependent species. This review highlight the eco friendly materials, their classification, uses...

Withstanding extinction while facing rapid climate change depends on a species' ability to track its ecological niche or to evolve a new one. Current methods that predict climate-driven species' range shifts use ecological modelling without eco-evolutionary dynamics. Here we present an eco-evolutionary forecasting framework that combines niche modelling with individual-based demographic and gen...

Energy efficiency enhancement has become an increasingly important issue for battery electric vehicles. Even if it can be improved in many ways, the driver's driving pattern strongly influences the battery energy consumption of a vehicle. In this paper, eco assist techniques to simply implement an energy-efficient driving assistant system are introduced, including eco guide, eco control and eco...

Ecological (eco) taxes are promising mechanisms to enable eco-friendly decisions, but few people prefer them. In this study, we present a way in which eco-tax options may be communicated to general public to encourage their payment. Our implementation (called “information presentation”) takes advantage of the non-linear relationship between eco-tax payments and CO2 emissions and the human relia...

Soil & Water Res., 10: 198–205. The hazards from wind, sand, and soil erosion caused by human activities, such as residue slopes in abandoned urban mines, have resulted in a vicious circle of environmental degrada...
