Environmental impacts conclusions

The energ /transport relationship is complex and resists easy generalization. Against this backdrop, what useful conclusions can he drawn about the role of passenger rail services in saving energy or reducing environmental impacts from transport ... [Pg.974]

All these assumptions can make a significant difference to the outcome of the study, and perhaps not surprisingly, assumptions made by organizations with a vested interest tended to support their product. Perhaps the overall conclusion from these studies is that the difference in overall impact is relatively small. How these products are used in practice may in fact be the most significant determinant of their relative environmental impact. [Pg.44]

Notably, however, any comparison of biodiesel vs. bioethanol should be done with great caution, because analysis of an industry such as that related to biofuels is a very complex task and all conclusions are country dependent. It may be interesting, however, to compare the energy balance and environmental impact in producing biodiesel from oilseed rape and bioethanol from wheat crops [4], Table 9.3 reports this comparison. The energy balance for bioethanol is more positive than for biodiesel, in particular when straw is utilized, mainly due to the higher yield... [Pg.185]

The impact of normal operation of the Eco Logic technology package on human health and the environment was addressed in the ACW I Committee report (NRC, 1999). That report s conclusion—that the health and environmental impacts are minimal—and the supporting information it contains are unchanged. [Pg.117]

Write a conclusion that summarizes the benefits and risks of both energy sources, in terms of their efficiency and environmental impact. [Pg.258]

In this book I use the term fetal programming —without reference to mechanism—to describe environmental impact of any kind on the fetus that produces alterations in health and disease apparent at any time in childhood or adulthood. This idea is essentially an extension into the prenatal period of more general conclusions about the role of early experience in later life. Included in this conception are postnatal temperament, behavior patterns, intelligence, psychopathology, and so on—the behavioral focus of this book. The point is that sometimes postnatal consequences of prenatal environmental impacts involve more than just alterations in the physiology of organ systems—such impacts can also have consequences for later behavior and cognitive performance. [Pg.88]

The SEI data is based mainly on earlier emission numbers for NiCd battery manufacturing, whereas the OECD monograph data represents updated emissions in the European Union as of 1994 compared to total volumes of cadmium utilized for NiCd battery production, based on information from the International Cadmium Association. All of this data indicates that most of the cadmium remains in the product and is not lost during NiCd battery manufacturing. A similar conclusion can be inferred with respect to nickel and cobalt, the other materials in a NiCd battery which might be likely to be regarded as hazardous and contribute to an adverse environmental impact. Iron, of... [Pg.11]

The court ruled that NIH failed to take a hard enough look at possible adverse effects and ordered a more formal review, or an environmental assessment. This review was completed and, not surprisingly, anticipates no significant ill effects if the test is carried out. If the opponents press their case as expected, the lower court will next rule on whether the environmental assessment s conclusions were made after a hard enough look. If not, an even more formal environmental impact statement will be required. This environmental impact statement would take a minimum of many more months, if not years, to complete. [Pg.387]

LCA is one of the widely used and important tools to measure the environmental impacts or environmental performance of a product considering the complete life cycle of a product, encompassing all its life cycle stages from cradle to grave. Environmental metrics of a studied product by LCA are solely dependent upon a term called functional unit (FU), which is the base considered by an LCA tool to map and measure the environmental impacts. Both for single and comparable products (based on the same functional level of course), the definition of a proper FU is pivotal to draw sensible results and to have a meaningful conclusion. [Pg.85]

Similar conclusions as in the previous study were reached here in this smdy as well, that is reusable bags have lower environmental impacts than all of the single-use bags, including both conventional HOPE bags and degradable bags. [Pg.292]

The conclusion of the study was that materials with low thermal conductivity (e.g. the eco-sandwich) enables the appUcation of relatively thin building envelopes, but the environmental impacts evaluated for the manufacture phase depend more on the type of materials used than on their weight. The system containing the eco-sandwich was the lightest, but the environmental impact due to the epoxy resin was very high. Nevertheless, light walls and roofs have the advantage that they are easy to erect. [Pg.317]

Modular subclassification makes it possible to allocate these material flows, and thus the environmental impacts, to individual process steps, facilitating identification of the polluter or source of contantination. When this basis has been established, and not before, an analysis of weak points and recognition of improvement potentials is possible. In some cases, initial conclusions concerning the defined objective can even be drawn on the basis of the databased balance. [Pg.421]

The impact assessment presents the databased balance in terms of environmental impact so as to derive conclusions concerning the overall impact. The databased balance thus provides the basis for the impact assessment. The aspects under investigation include the potential environmental impacts (e.g., climate change, ozone depletion, acid rain) caused by the input and output flows over the entire lifecycle. [Pg.423]

In conclusion, MIMS instruments proved to have great potential for utilization in continuous VOC-monitoring stations. These instruments are reliable, cost-effective and simple to use they have no environmental impact because no solvent is used for the extraction of organics from water, and they can be located on-site, unattended, providing a continuous flow of data on water quality and pollution. [Pg.505]

The article combined with Tengchong Qinghai lake basin natural environment condition and development history to comprehensively analyze. Achieved a conclusion that RCl representative environmental impact factor is precipitation and RC2 representative environment impact factor is temperature (Fig. 4). [Pg.200]
