Life cycle assessment (LCA) is increasingly used in waste management to identify strategies that prevent or minimise negative impacts on ecosystems, human health or natural resources. However, the quality of the provided support to decision- and policy-makers is strongly dependent on a proper conduct of the LCA. How has LCA been applied until now? Are there any inconsistencies in the past practice? To answer these questions, we draw on a critical review of 222 published LCA studies of solid waste management systems. We analyse the past practice against the ISO standard requirements and the ILCD Handbook guidelines for each major step within the goal definition, scope definition, inventory analysis, impact assessment, and interpretation phases of the methodology. Results show that malpractices exist in several aspects of the LCA with large differences across studies. Examples are a frequent neglect of the goal definition, a frequent lack of transparency and precision in the definition of the scope of the study, e.g. an unclear delimitation of the system boundaries, a truncated impact coverage, difficulties in capturing influential local specificities such as representative waste compositions into the inventory, and a frequent lack of essential sensitivity and uncertainty analyses. Many of these aspects are important for the reliability of the results. For each of them, we therefore provide detailed recommendations to practitioners of waste management LCAs. 相似文献

Green specifications constitute one of the important elements in green construction. New sustainability requirements and changing priorities in construction management have spurred the emerging green specifications to a faster pace of development. A cross-sectional survey has been conducted in Hong Kong in 2007 to identify principal factors leading to the success of preparing green specifications. Based on extensive construction management literature, 20 variables concerning sustainable construction were summarized. Using the Mann–Whitney U-test, the subtle differences between stakeholders in specifying construction work have been detected even with the high consistency of the responses among the groups. Moreover, five independent factors for successful specification of green construction have been categorized by factor analysis. They are related to (1) green technology and techniques, (2) reliability and quality of specification, (3) leadership and responsibility, (4) stakeholder involvement, and (5) guide and benchmarking systems. Whilst the first and fourth factors are generally more important, different stakeholder groups have different emphases. The results of the survey have been validated against established principles. 相似文献

Human beings have engaged in animal husbandry and have slaughtered animals for food for thousands of years. During the majority of that time most societies had no animal welfare regulations that governed the care or slaughter of animals. Judaism is a notable exception in that from its earliest days it has included such rules. Among the Jewish dietary laws is a prohibition to consume meat from an animal that dies in any manner other than through the rigorously defined method of slaughter known as shechita. In recent decades more and more attempts have been initiated by governments around the world to either outright ban or to control and modify the practice of shechita. This paper presents the requisite background about shechita and then analyzes the ethics of some of the recent legislation. The analysis includes a rebuttal of the assertion that shechita is an inhumane method of slaughter. It further presents the consequences on the Jewish community of legislation to impose pre-slaughter stunning and explains why such legislation is unethical. The actual effect of labeling laws is discussed and it is shown why such laws are also un-ethical. 相似文献
