Opportunities and constraints for Product-oriented Environmental Management Systems (P-EMS)

Product-oriented Environmental Management Systems (P-EMS) are a logical extension of current, often primarily process- of facility-oriented Environmental Management Systems. The Dutch government promotes P-EMS as part of its product-oriented environmental policies. The idea of P-EMS is to enable producers to make environmentally responsible decisions on product development and product strategies, in collaboration with suppliers and customers. This paper summarises example P-EMS projects in The Netherlands for two segments of industry, namely retail and manufacturing industry. Moreover two other initiatives will be covered that deal with the development of tools to facilitate P-EMS in two other industry sectors (food processing and building). Success factors that emerge from these initial experiences are: focus on partners that have a strong incentive to act, application of screening Life Cycle Assessments (LCA) or user-shells for LCA, and focus on improvements that can be implemented on the short term.     

欧洲的氮状况

欧洲(不包括前苏联)的氮收支表明,欧洲氮循环加速的三个主要驱动力是肥料生产(14MtN/a)、矿物燃料燃烧及其它工业(3.3MtN/a)和各种产品中的氮输入(7.6MtN/a).本文估计了欧洲粮食、能源和工业产品系统中活性氮元素的各种泄漏,评估了它们对人类健康及水陆生态系统的影响.考虑到氮流转中的可能后果,未来欧洲有关封闭氮循环和减少活性氮泄漏的环境政策措施最好集中于三个主要驱动力.在确定氮排放上限和制定氯流控制的综合政策方面,如肥料使用、输入和氮水平,临界负载可能是非常有用的工具.

e-Serem – A Web-Based Manual For The Estimation of Emission Reductions From JI and CDM Projects

This paper presentse-SEREM (Smart Emission ReductionEstimation Manual), a cost-free, easilyaccessed and updated, web-based manual forestimating emission reductions from Joint Implementation (JI) andClean Development Mechanism (CDM) projects. e-SEREM's main functions arethe selection of a benchmark for a specificproject type in the power or heat sectorand the calculation of the annual andcumulative emission reductions accrued bythis project for its crediting lifetime.e-SEREM was developed in order to test itsapplicability and practicality in assistingproject developers and evaluators toelaborate baselines easily and calculatethe emission credits earned by candidate JIor CDM projects hosted in several countries.
