在全球节能减排的宏观政策之下,我国洗涤行业的逐步发展与壮大应符合国家节能减排的整体方向和目标,加强节能减排意识,实施有关节能减排的措施,走可持续发展的道路.本文通过对国外发达国家洗涤行业节能减排的政策、方法和经验的了解和学习,结合我国洗涤行业的实际特点,旨在找到适合我国洗涤行业的可持续发展道路.研究表明,虽然我国洗涤行业还处于快速扩大发展的初期,但我国可以根据自身的具体情况有选择性地借鉴国外发展和节能减排的经验和方法,在此基础上,结合具体实际特点,开拓创新,开发出适合我国洗涤行业的可持续发展道路,在快速扩大发展的同时,与其他行业和领域一同为实现我国的节能减排目标而努力. 相似文献

Mechanical recycling of 100% post-consumer plastic waste into high-quality products has been performed. The chemical and physical properties of these recycled materials have been compared with similar products manufactured from virgin resins. The properties of a blow-moulded bottle prepared from 100% post-consumer high-density polyethylene (HDPE) showed that this recycled polymer exceeded the materials specifications for virgin plastic designs. Similarly, a sample of thermoplastic polyolefin (TPO, 100% polypropylene), obtained entirely from shredder residue (SR) displayed sufficient material strength for future separation and reprocessing. 相似文献

This article outlines some of the latest developments and opportunities for development finance institutions1 (DFIs) to become directly supportive of the Clean Development Mechanism (CDM2) in Africa. In striving to make development financing more environmentally friendly and sustainable, DFIs can play a key
role in promoting the CDM on the African continent by providing monetary incentives through their project financing activities;
encouraging and facilitating partnerships in support of sustainable development, particularly with reference to the CDM, and;
providing technical advice and support to clients with regard to project design, planning and implementation.
DFIs have traditionally focused on financing infrastructure and poverty alleviation projects. However, the emergence of the
CDM has brought about a shift towards investments in services and products that reduce carbon dioxide emissions and encourage
investments in environmentally friendly technologies. This can be ascribed in part to the development of a “carbon market”
under the auspices of the Kyoto Protocol that took effect in February 2005. The carbon market and emerging carbon funds are
some of the main drivers enabling DFIs to play an increasingly important role in promoting the CDM in Africa. 相似文献

This paper focuses on the linkages between water and trade policies, using Morocco as a case. This country is typical of many in that policy protects its import competing agricultural and industrial sectors while water in irrigated agriculture is priced below its marginal value product. Changing water policy without correcting for these other distortions leads to a more inefficient allocation of water. On the other hand, reforming trade policy alone can make farmers growing crops protected pre-reform worse off. Using an intertemporal, applied general equilibrium model, we find that trade reform actually creates an opportunity to pursue water policy reform. Creating a water user-rights market post trade reform not only compensates for the decline in farmers’ profits caused by the trade reform, but also raises the efficiency of water allocation and hence benefits the economy as a whole. 相似文献

The regenerative capacity of ecosystems provides a regulatory basis for sustainable economic growth and development. A natural valuation of an ecosystem's services will arise in a market for developmental rights in the ecosystem using a unit of tradable 'right': E-Scrip. The amount of e-scrip needed for a development may be set by Environmental Assessment. The capacity of the ecosystem to regenerate with developmental pressure may be represented by an independent trader or Factor Proxy for the Environment who provides e-scrip to the market. 相似文献

In December 2010, the German government increased the maximum ethanol content that can be blended with petrol from 5% to 10%, which facilitated the introduction of the ethanol–petrol blend E10. The revised ethanol–petrol blend was introduced with ambitions towards decarbonizing the transport sector as well as to support energy security and rural development. While usually supportive of actions aimed to combat climate change, the great majority of German motorists have refused to buy E10. The lacking demand for E10 is the empirical phenomenon addressed by this study. How did the fuel suppliers comply with the policy provisions? Which actors made attempts to influence the motorists’ demand for the new ethanol–petrol blend? Which actor was assigned the responsibility for the problems that occurred upon the rollout of the new fuel type? These research questions guide this study, which concentrates on the behaviour of transport fuel suppliers and consumers in mandated markets, that is, markets created by policy provisions. 相似文献

The article quantifies the size of ‘hidden’ social costs that are incurred by forestry offsets in the voluntary market that
promise to offset present emissions sometime in the future. It does this by estimating the difference between the social costs
of carbon (C) emitted and of costs offset by removal of C from the atmosphere by reforestation/afforestation. All current
attempts to make forestry offsets more reliable focus on quality control rather than the mismatch of the timing of emissions
and their offset. Recommendations that follow from the analysis are twofold. First, that markets for carbon dioxide equivalent
(CO2e) removals by voluntary offsets should be confined to the annual incremental removals actually achieved. Second, the
promoters of voluntary offsets projects should declare the annual stream of carbon credits and debits expected so that buyers
can place a present value on such projects. 相似文献

The sitting comfort of office chairs with different ergonomic layouts (inferior, superior) was examined. Fifty participants were randomly assigned to a 2 × 5 factorial experimental design with 2 different conditions of ergonomic chair layout (inferior or superior) and 5 different conditions of instruction to explore the chair. Four conditions were created to differentiate between various levels of perceptual awareness and processing of chair-related information (guided exploration and developed evaluation). In a 5th condition, participants remained uninstructed (free exploration and intuitive exploration). Under guided exploration, the participants’ perception of sitting comfort was in line with objective differences in the chair layout. Different conditions of guided exploration, however, did not influence the evaluations. Under free exploration, the participants’ perceptions did not match the ergonomic chair layout. In contrast to participants under guided exploration, they even rated the ergonomically inferior office chair more favourably than the ergonomically superior chair. 相似文献

Impact of groundwater markets in India on water use efficiency: a data envelopment analysis approach
Manjunatha AV Speelman S Chandrakanth MG Van Huylenbroeck G 《Journal of environmental management》2011,92(11):2924-2929
In the hard rock areas of India, overdraft of groundwater has led to negative externalities. It increased costs of groundwater irrigation and caused welfare losses. At the same time informal groundwater markets are slowly emerging and are believed to improve water distribution and to increase water use efficiency in the irrigation sector. These claims are evaluated in this study. For this purpose data was collected from a sample containing three different groups of water users: water sellers, water buyers and a control group of non-traders. First the socio-economic characteristics of these groups are compared. Then the efficiency of water use of the three groups is studied using Data Envelopment Analysis. The results indicate that groundwater markets provide resource poor farmers access to irrigation water, giving them the opportunity to raise their productivity. Water buyers are furthermore shown to be most efficient in their water use, while water sellers are also shown to be more efficient than the control group. The differences in efficiency between the groups are statistically significant. The demonstrated potential of groundwater markets to improve the efficiency of water use and to increase equity in resource access should be taken into account by the Indian government when deciding on their attitude towards the emerging groundwater markets. 相似文献
