This paper addresses synergies between the Millennium Development Goals (MDGs) and the Clean Development Mechanism (CDM), and considers how the CDM can facilitate the MDGs in Pacific Island Countries (PICs). To date, only 6 CDM projects have been registered in PICs, highlighting the ‘lose-lose’ business case that applies to this type of project development. This paper identifies constraints on and opportunities for CDM project development in PICs, and proposes a range of specific policy reform measures that could alter existing negative investment profiles. Key findings are that small-scale agricultural projects providing renewable energy from existing sources of biomass (currently seen as waste) are ideal candidates for CDM investment in PICs, and that the single most important reform to facilitate CDM activity and contribute to achieving the MDGs would be the implementation of a regional approach to CDM administration, in which a regional body became the designated CDM Authority for all states in the region. This would offset investment risk, improve governance transparency, and facilitate a targeted approach to sustainable development activities in the Pacific region. 相似文献

甘肃黄土丘陵地区冬季温度多处于0 ℃以下,农户取暖水平低。论文通过实地观测记录获取数据,建立趋势面模型,核算采暖期累计温差和实际用能消耗,提出以16 ℃的室内温度为小康取暖标准。参考国家相关标准,比较实际用能和应用节能技术下用能的热效率。结果表明,陇东长官村和陇中河畔村农户采暖期累计温差分别为23 002 h·℃和36 390 h·℃,实际取暖能耗分别为926 kgce/a和1 199 kgce/a。农户取暖用能数量虽不少,但目前只解决了小康水平下39.6%和46.6%的取暖需求。取暖用能的综合热效率只有17%左右。如果应用节能技术,能耗会大幅降低,提高综合热效率的潜力巨大。因此,通过住房的节能改造和用能设施的改善来提高房屋的保暖性、降低单位面积的热损耗是今后解决取暖用能问题的主要方向。 相似文献

Carbon dioxide emissions from 1990 to 2100 AD are decomposed into the product of four factors: population size, affluence (measured here as GDP per capita), energy intensity (energy use per unit GDP) and carbon intensity (carbon dioxide emissions per unit energy). These emissions factors are further subdivided into three regions: more developed countries (MDCs), China, and the remaining less developed countries (LDCs). Departures from a baseline scenario (based on IPCC, 1992a — the so-called ‘business-as-usual’ scenario) are calculated for a variety of alternative assumptions concerning the four emissions factors in the three regions. Although the IPCC scenario is called a ‘non-intervention’ scenario, it is shown, for example, that large decreases in energy intensity in China or carbon intensity in MDCs are built into the ‘business as usual’ case — and such large changes vary considerably from region to region. We show what CO2 emissions would look like if each of these four emissions factors projected in the baseline case somehow remained constant at 1990 levels. Certain factors like energy intensity improvements and long-term population growth in LDCs, or GDP growth and carbon intensity improvements in MDCs, are shown to have a big contribution to cumulative global emissions to 2100 AD, and consequently, changes in these projected factors will lead to significant deviations from baseline emissions. None of the scenarios examined in this analysis seems to indicate that any one global factor is clearly dominant, but cultural, economic, and political costs or opportunities of altering each factor may differ greatly from country to country. 相似文献

The number of organizations contemplating the integration of environmental practices into their strategic plans and daily operations is continuously increasing. Numerous initiatives have provided incentives for organizations to become more environmentally benign. Some of these regulation driven programs are mandatory, but increasingly numerous voluntary environmental programs are also introduced by organizations. Organizations view many of these environmental programs, which may include technological and organizational development projects, as possible alternatives for gaining or maintaining a competitive advantage. One environmental program area that continues to gain in importance is one that focuses on the external relationships among organizations. To help evaluate alternatives that will effect this relationship we present a strategic decision framework that will aid managerial decision-making. This decision framework is based on literature and practice in the area of environmentally conscious business practices. The focus of this paper will be on the components and elements of green supply chain management and how they serve as a foundation for the decision framework. We shall explore the applicability of a dynamic non-linear multiattribute decision model, defined as the analytical network process, for decision making within the green supply chain. Issues facing the modeling approach are also discussed. 相似文献

环境NGO及其制度机理 总被引:4,自引:1,他引:3
环境NGO是政府和企业之外参预环境治理的"第三力量",其活动涵盖了环境治理的各个方面。环境NGO的非政府性、非营利性和自发性等特征,使其在环境治理中发挥了不可替代的作用。作为一种具有创新性的制度安排,环境NGO突破了政府主导环境治理的局限,实现了环境治理制度的多样化。其作用机理在于环境利益的诉求主体明确,交易成本较低,治理结构合理等。中国环境NGO制度尚不完善,整体水平较低,亟需加以改进。 相似文献

沂蒙山区农户生计变迁及其住宅形态的响应研究 总被引:4,自引:1,他引:3
以山东省沂水县3个村(核桃园、高桥、唐家庄子)为例,运用参与式农村评估法(PRA)、对比分析法,剖析沂蒙山区农户生计变迁与其住宅形态功能转型的关系,为农村居民点整治中的新村建设提供决策指导。研究结果表明:1)改革开放前,研究区农户以农业生计为主,修建“平房+庭院”形态住宅,利用庭院种植蔬菜;2)改革开放后,农户生计逐渐多样化和非农化。禽畜养殖成为农户重要的生计来源,农户在住宅内搭建猪圈养猪,在庭院内饲养家禽。高桥农户就地发展非农经济,修建两层楼房,将一层的空间用于非农经营;3)21世纪以来,农户生计进一步非农化和分化。核桃园农户以粮食种植和外出务工为主,将庭院硬化晾晒粮食,改造猪圈为储物间储存粮食和农机具;高桥农户为了扩大非农经营空间修(改)建三层楼房,将一二层用于非农经营;唐家庄子农户到县城非农就业,为改善居住环境修建两层楼房,住宅中用于生产的空间消失。可见:农村住宅形态和功能转型是与农户生计方式变迁相适应的,农村居民点整治中新村建设模式应充分考虑农户生计的实际需求。 相似文献

Russia is one of the most energy- and carbon-intensive countries in the world. The high level of technical abrasion and a
low level of investments into modernization of the Russian energy industry cause huge energy wastage and carbon emissions.
This situation is regarded by countries relying on energy imports from Russia as an increasing threat to security of supply
and as a major barrier to global climate change policy. This paper provides an overview of the current and future Russian
energy efficiency and greenhouse gas mitigation policies. The focus is laid on the detailed investigation of the progress
and future potential of the market-oriented mechanisms Joint Implementation (JI) and Green Investment Scheme (GIS), being
considered as two possible channels for FDI in transnational energy efficiency and carbon mitigation projects. The analysis
was conducted by reviewing the relevant scientific and non-scientific literature including a variety of theoretical and practice-oriented
arguments. Based on this assessment, we conclude that JI and GIS are confronted with numerous barriers in the Russian energy
market. We further scrutinize the ability of Energy Service Companies (ESCOs), as one of the market intermediary models, to
overcome some of these barriers in the process of effectively integrating JI and GIS in their long-term business strategies.
Due to the compatibility of the main features of JI and GIS with the working procedures under the ESCO model we conclude that
numerous synergy effects can be generated and that the majority of transaction barriers specific for the Russian energy market
can be overcome. Such an integrative framework for international energy efficiency and carbon mitigation projects would contribute
to the modernization of the Russian energy industry and enable a “win-win” situation for foreign companies seeking to invest
in a sustainable manner. 相似文献

Besides energy conservation, theexploration of renewable energy sources, inparticular biomass and solar energy, arecentral aspects of the Austrian energypolicy, regarded as an optimal option forachieving CO2-emission reductionobjectives.The market penetration of RenewableEnergy Technologies in the last twentyyears was supported by the AustrianEnergy Research Programme. The result ofsuccessful developments of biomass heating,solar thermal, solar electrical and windenergy technologies is the key for themarket development of these renewableenergy technologies.With the market penetration of renewableenergy technologies new business areas wereestablished and employment created.Today, some renewable energy technologiesin Austria have reached economiccompetitiveness. Some technologies notreached commercialisation, and need moredevelopment to improve efficiency,reliability and cost to become commercial.This would include material and systemdevelopment, pilot plants or fieldexperiments to clarify technical problems,and demonstration plants to illustrateperformance capabilities and to clarifyproblems for commercialisation. 相似文献

Carbon capture and storage (CCS) may become a key technology to limit human-induced global warming, but many uncertainties prevail, including the necessary technological development, costs, legal ramifications, and siting. As such, an important question is the scale of carbon dioxide abatement we require from CCS to meet future climate targets, and whether they appear reasonable. For a number of energy technology and efficiency improvement scenarios, we use a simple climate model to assess the necessary contribution from CCS to ‘fill the gap’ between scenarios’ carbon dioxide emissions levels and the levels needed to meet alternative climate targets. The need for CCS depends on early or delayed action to curb emissions and the characteristics of the assumed energy scenario. To meet a 2.5°C target a large contribution and fast deployment rates for CCS are required. The required deployment rates are much faster than those seen in the deployment of renewable energy technologies as well as nuclear power the last decades, and may not be feasible. This indicates that more contributions are needed from other low-carbon energy technologies and improved energy efficiency, or substitution of coal for gas in the first half of the century. In addition the limited availability of coal and gas by end of the century and resulting limited scope for CCS implies that meeting the 2.5°C target would require significant contributions from one or more of the following options: CCS linked to oil use, biomass energy based CCS (BECCS), and CCS linked to industrial processes. 相似文献
