碳责任账户的目标原则、分配逻辑与框架构建：账户建立

随着全球环境问题日趋严重,企业和消费者日益认识到减缓气候变化的紧迫性。作为经济活动的主要参与者,减少温室气体排放已经成为任何单个企业及其供应链的巨大挑战。供应链的所有参与者都需要为气候减缓做出努力。现有的碳排放责任核算大多从企业的生产方面入手。最终消费者作为供应链的重要参与者,是所有生产者的最终服务对象,同样具有不可忽视的碳减排作用以及应承担的碳减排责任。本文提出以产品为导向,考虑产品生产过程中的直接碳排放和间接碳排放,建立产品碳排放基准值,对基于供应链的所有参与主体进行责任分配,进而建立基于供应链的碳责任账户。本文构建的责任体系框架具有更广泛、更有前景的应用潜力。     

烹饪油烟污染与处理技术探讨

为了降低油烟对环境的污染,分析了油烟中的主要污染物成分及油烟对人体健康的几种危害。讨论了五种油烟净化技术:惯性分离法、过滤分离法、液体洗涤法、静电沉积法、复合技术。分析了液体洗涤油烟净化技术的原理、水循环利用时对洗涤废液进行的油水分离,提出了采用流场分析喷淋,以了解其流场的特性。结果表明,采用液体洗涤法去除油烟效率高,安全可靠。     

沟谷泥石流运动过程模型试验

泥石流运动过程是泥石流运动力学核心内容之一.以新疆天山公路K630泥石流为原型,选取几何相似比1:650,推导了泥石流质量、固液两相流速和泥石流冲击力相似比,以流通区为核心,建造了沟谷泥石流试验模型.试验结果表明,泥石流运动具有显著的阵流特性,阵流间隔时间为10s左右,其间嵌套2~3次弱阵现象;阵流期间,泥石流流速和冲击力均较大;从流通区的源头至沟口,流速呈现非线性增大趋势,且泥石流体中固液两相流速变化趋势相似,弯道处泥石流超高现象显著;泥石流运动初期由于泥石流体中固相和液相混和搅拌不均匀而呈现稀性泥石流特征,随后粘性特性增强.这些现象与现场观测结果基本一致.     

Connotation and principles of ecological compensation in water source reserve areas based on the theory of externality

Understanding the connotation and principles of ecological compensation in water source reserve areas is the basis and guarantee for establishing and improving the ecological compensation mechanism of water source reserve areas. First, this paper reviews the three stages of ecological compensation research progress. Based on the review, using the theory of externality, the ecological environment system of water source reserve areas is then analyzed. This paper argues that the connotation of ecological compensation in water source reserve areas is a kind of institutional arrangement, which is designed to internalize externalities. Finally, based on the understanding of the connotation of ecological compensation in water source reserve areas, five principles for establishing and improving the ecological compensation mechanism are proposed, including the principle of fairness and justice, the principle of equivalence of equality and responsibility, the principle of flexibility and effectiveness, the principle of “earmark funds, and implementation by law,” and the principle of government compensation supplemented with market compensation.

Carbon capture and storage-desirability from a risk management point of view

Environmental and safety risks related to carbon capture and storage concern leakages and accidental releases during transport and geological storage. Based on principles widely accepted in the EU and beyond in the discussion about the where’s and why’s of nuclear waste repositories, this paper discusses the desirability of carbon capture and storage from a risk management point of view, focusing on environmental risks on the global level (climate change). On this basis it is concluded that, if the key energy issue of coming generations, not just in Europe but all around the world, is not the abundance of fossil resources but rather an unacceptably high probability of global warming due to greenhouse gas emissions, then the solution should not include any massive hiding of the emissions but entirely focus on the avoidance based on improved technology in power plants and other industrial installations.
