从拒绝《京都议定书》看美国政府环境外交意图

作为国际社会最具影响力的环境协约,《京都议定书》却被美国政府拒之门外,通过对美国近年来针对该协约的态度及对全球变暖问题的外交举措分析,可以看出,美国政府环境外交行为的意图主要体现在三个方面,即规避不利条款的束缚;设计和实施替代性方案;积极争取国际环境领域的领导地位。     

The impact of economic activity in Asturias on greenhouse gas emissions: consequences for environmental policy within the Kyoto Protocol framework

Climate change is one of the major worldwide environmental concerns. It is especially the case in many developed countries, where the greenhouse gas emissions responsible for this change are mainly concentrated. For the first time, the Kyoto Protocol includes an international agreement for the reduction of the net emissions of these gases. To fulfil this agreement measures designed to reduce or limit current emissions have to be brought into force. Consequently, fears have arisen about possible consequences on competitiveness and future development of manufacturing activities and the need for support mechanisms for the affected sectors is obvious. In this paper, we carry out a study of the emissions of gases responsible for climate change in Asturias (Spain), a region with an important economic presence of sectors with intensive emissions of CO(2), the chief greenhouse gas. To be precise, in the first place, the volumes of direct emissions of the said gases in 1995 were calculated, showing that the sectors most affected by the Kyoto Protocol in Asturias are iron and steel and electricity production. Secondly, input-output analysis was applied to determine the direct and indirect emissions and the direct, indirect and induced emissions of the different production sectors, respectively. The results derived from the direct and indirect emissions analysis and their comparison with the results of the former allow us to reach some conclusions and environmental policy implications.     

Conflictive sustainability landscapes: the neoliberal quagmire of urban environmental planning in Buenos Aires

The government of Canada ratified the Kyoto Protocol on 17 December 2002, but over 100 Canadian municipalities had joined the International Council for Local Environmental Intitatives' (ICLEI) Cities for Climate Protection (CCP) campaign up to a decade earlier. A low-cost home energy rating system (HERS) evaluation and individualized energy plan was provided to 420 households in Kitchener, Ontario, from September 2000 to August 2001. To assess the impact of the energy efficiency program, natural gas consumption in the year prior to the evaluation was compared with that in the year following. Overall, a 5% reduction was achieved, but individual responses varied widely. Situational and psychological factors were evaluated for three groups of households: the conservers, the consumers and the steady middle group. Conservers (30% of households) had higher initial energy consumption levels and achieved two-thirds of the potential savings identified by the energy evaluation. Consumers (12% of households) had higher ownership rates of high-efficiency furnaces and water heaters and demonstrated the rebound effect of increased demand for energy services following the evaluation. Low-income groups were the most likely to behave as conservers (42%) while high-income groups were the least likely to be conservers (13%) and the most likely to be consumers. Local programs need to be inclusive of all income groups to increase participation and implementation rates by systematically reducing barriers (financial, knowledge, trust) or increasing incentives (financial, regulatory or social) if the desired goal (e.g. Kyoto target) is to be achieved.     

Advancement of renewables in Bangladesh and Thailand: Policy intervention and institutional settings

This article reviews and analyses the advancement of renewable sources of energy in Bangladesh and Thailand in terms of policy intervention and institutional settings. Since renewable forms of energy emit far smaller amounts of greenhouse gas compared with fossil fuels, their use should mitigate climate change impacts while contributing to the provision of energy services. The article turns first to a review of energy–environment trends and the potential for renewables in these two nations. It then discusses strategies for the advancement of renewables. It is argued that further significant efforts can be made towards the advancement of renewables in Bangladesh and Thailand. These two nations could also learn from the experience in industrialized nations and other developing nations with regard to requisite policy instruments and processes. A number of barriers remain to the advancement of renewables, especially in terms of policy arrangements, institutional settings, financing mechanisms and technologies. Resources, cooperation and learning are required in order to overcome such barriers and to foster the development of necessary policy measures. Implementation of the clean development mechanism (CDM) under the Kyoto Protocol, and replication and adaptation of effective strategies from other settings are possible avenues for this.     

Transaction costs and the clean development mechanism

The emissions trading provisions of the Kyoto Protocol and its clean development mechanism (CDM) are designed to permit greenhouse gas (GHG) emission reductions at the lowest cost globally. However, to ensure climate integrity, these reductions must pass through vigilant approval, monitoring and evaluation procedures that create additional transaction costs unrelated to the physical process of eliminating GHGs. Moreover, the CDM's additionality criterion creates constraints that magnify the influence of these transaction costs on project viability. If these costs are extreme, they could undermine the success of the CDM, and possibly of the Kyoto Protocol itself. This article describes the trading provisions of the treaty, creates a working definition of transaction costs, and discusses their effects. It then analyzes the process of creating a CDM project to identify the sources of transaction costs, illustrated by an example of a fuel substitution project in Ghana. The conditions for project profitability are analyzed and compared with recent GHG emission credit prices in Europe. The specific Ghanaian results are not generalizable to all CDM projects, but the model does suggest a template that can be used to analyze the effects of project and transaction costs in other contexts.     

Strategies for emission reduction from thermal power plants

Major polluters of man's environment are thermal power stations (TPS) and power plants, which discharge into the atmosphere the basic product of carbon fuel combustion, CO2, which results in a build-up of the greenhouse effect and global warm-up of our planet's climate. This paper is intended to show that the way to attain environmental safety of the TPS and to abide by the decisions of the Kyoto Protocol lies in raising the efficiency of the heat power stations and reducing their fuel consumption by using nonconventional thermal cycles. Certain equations have been derived to define the quantitative interrelationship between the growth of efficiency of the TPS, decrease in fuel consumption and reduction of discharge of dust, fuel combustion gases, and heat into the environment. New ideas and new technological approaches that result in raising the efficiency of the TPS are briefly covered: magneto-hydrodynamic resonance, the Kalina cycle, and utilizing the ambient heat by using, as the working medium, low-boiling substances.     

What is driving the EU burden-sharing agreement: Efficiency or equity?

Under the Kyoto Protocol the European Union agreed to reduce emissions of greenhouse gases by 8 percent. The Burden-Sharing Agreement (BSA) redistributes the reduction target among the member states. The purpose of this paper is to evaluate the BSA. To determine if cost efficiency was considered, marginal abatement costs (MACs) are first calculated based on an estimation of the directional output distance function using country production data for 1990-2000. MACs, together with equity indicators, are then regressed on the emission change targets. The main conclusion is that both efficiency and equity were important aspects considered in the settlement.     

Greening the Brazil,Russia, India,China and South Africa (BRICS) economies: Assessing the impact of electricity consumption,natural resources,and renewable energy on environmental footprint

Electricity consumption is a crucial factor in the environmental pollution process, and therefore, its impact needs to be carefully considered by policymakers. This study investigates the relationship between energy consumption, electricity generation, natural resource utilization, and environmental pollution in BRICS nations, which have a substantial share in global resource consumption. To this end, we employed a novel methodology, namely the Method of Moment Quantile Regression (MMQR), for the time period between 1990 and 2018, within the framework of the Environmental Kuznets Curve (EKC) theory. The study's outcome shows that natural resources and renewable energy are efficacious and significant in curbing environmental degradation among the sample countries. The investigation reveals a positive correlation between electricity consumption and environmental degradation, thereby highlighting this vital resource's role in exacerbating the BRICS nations’ ecological footprint. The findings from this research can provide crucial insights for policymakers to achieve sustainable development and carbon neutrality in these countries.     

The benefits of proactive environmental quality: Tips from a successful small business

Who says environmental quality has to cost a bundle? Or that it's out of reach of the typical smaller company? In fact, says this article, a proactive environmental quality program offers significant cost-avoidance opportunities and can allow a company to reap positive public relations rewards. The combination of a total quality production program and a proactive environmental quality program is a formidable force for success. And you don't have to be a big company to be an environmental leader.© 1999 John Wiley & Sons, Inc.     

Who changes consumption following residential energy evaluations? local programs need all income groups to achieve kyoto targets

Sustainable development in the Clean Development Mechanism: the role of Designated National Authority in China and India

The Clean Development Mechanism (CDM) emerged under the Kyoto Protocol to facilitate collaboration between developed and developing countries in order to mitigate greenhouse gases. The CDM allows developed countries to receive credits towards meeting their obligatory targets by investing in emission reduction projects in developing countries. The countries are required to set up a Designated National Authority (DNA) to approve the CDM projects. This paper examines the role of the DNA in ensuring sustainable development, using the empirical case of China and India. Three aspects of the DNA's role are examined: the institutional structure, the policy context and the CDM project market. All three aspects highlight the important role of the DNA in meeting the countries' sustainable development priorities.     

Rethinking the management of transboundary freshwater resources: a critical examination of modern international law and practice

Available freshwater stocks are being depleted and impaired on a widespread basis, with acute shortages an increasingly frequent condition in arid climates. In transboundary basins, water scarcity and pollution compound interstate tension and contribute to human suffering and ecological damage. This article provides theoretical perspectives on shared freshwater disputes and on the evolution of the international law of shared water resources. It argues that the UN Convention on the Non-Navigational Uses of International Watercourses (ratified by some countries, but not yet in force) is inadequate as a framework convention in terms of providing general obligations on the future parties or an institutional framework for future action. The paper suggests that three critical concepts be considered in future management of shared water resources: (1) the unitary character of watersheds (where the absence of extra-basin diversions allows); (2) joint or "communitarian" watershed management; and (3) the relevance of international trade to alleviating regional food stress, resulting from local water scarcity. Finally, it proposes the establishment of an international advisory body on shared water disputes, modelled after the Intergovernmental Panel on Climate Change (IPCC), whose role is codified in the Kyoto Protocol to the United Nations Framework Convention on Climate Change.     

The Ethics of Burden-Sharing in the Global Greenhouse

The Kyoto Protocol on global warming has provoked great controversy in part because it calls for heavier burdens on wealthy countries than on developing countries in the effort to control climate change. The U.S. Senate voted unanimously to oppose any agreement that does not require emissions reductions in low-income countries. The ethics of this position are examined in this paper which shows that there are good moral reasons for supporting the provisions of the Kyoto Protocol. Such a conclusion follows easily from considerations of distributive justice but can also be supported by more narrowly self-interested arguments. This revised version was published online in July 2006 with corrections to the Cover Date.     

Adsorptive cooling: a clean technology

As a consequence of the Kyoto Protocol and its predecessor, the Montreal Protocol, environmental considerations will play an important role in the choice of a refrigeration or heat pump system. Accordingly, sorption technology is expected to develop for cooling as well as for heat pump applications because it uses benign fluids. At the moment, liquid absorption technology is the leading technology in that field; however, adsorption offers advantages that cannot be achieved by liquid absorption technology. This article addresses the measures to reduce halocarbon emissions and the possibilities of adsorption technology. Not only are the direct emissions taken into account but also the indirect ones due to energy consumption. Several cases that show that adsorption cooling is very promising, from the global warming point of view, are considered in this article. They are: waste heat adsorption chilling, natural gas adsorption chilling, trigeneration and natural gas reversible heat pump. Adsorption air conditioning for automobiles is also discussed as a very challenging possibility for adsorption cooling.     

Environmental Impact Assessment Under the National Environmental Policy Act and the Protocol on Environmental Protection to the Antarctic Treaty

US government actions undertaken in Antarctica are subject to the requirements of both the Protocol and the US National Environmental Policy Act (NEPA). There are differences in the scope and intent of the Protocol and NEPA; however, both require environmental impact assessment (EIA) as part of the planning process for proposed actions that have the potential for environmental impacts. In this paper we describe the two instruments and highlight key similarities and differences with particular attention to EIA. Through this comparison of the EIA requirements of NEPA and the Protocol, we show how the requirements of each can be used in concert to provide enhanced environmental protection for the antarctic environment. NEPA applies only to actions of the US government; therefore, because NEPA includes certain desirable attributes that have been refined and clarified through numerous court cases, and because the Protocol is just entering implementation internationally, some recommendations are made for strengthening the procedural requirements of the Protocol for activities undertaken by all Parties in Antarctica. The Protocol gives clear and strong guidance for protection of specific, valued antarctic environmental resources including intrinsic wilderness and aesthetic values, and the value of Antarctica as an area for scientific research. That guidance requires a higher standard of environmental protection for Antarctica than is required in other parts of the world. This paper shows that taken together NEPA and the Protocol call for closer examination of proposed actions and a more rigorous consideration of environmental impacts than either would alone. Three areas are identified where the EIA provisions of the Protocol could be strengthened to improve its effectiveness. First, the thresholds defined by the Protocol need to be clarified. Specifically, the meanings of the terms “minor” and “transitory” are not clear in the context of the Protocol. The use of “or” in the phrase “minor or transitory” further confuses the meaning. Second, cumulative impact assessment is called for by the Protocol but is not defined. A clear definition could reduce the chance that cumulative impacts would be given inadequate consideration. Finally, the public has limited opportunities to comment on or influence the preparation of initial or comprehensive environmental evaluations. Experience has shown that public input to environmental documents has a considerable influence on agency decision making and the quality of EIA that agencies perform.     

Temporal pessimism and spatial optimism in environmental assessments: An 18-nation study

The personal assessments of the current and expected future state of the environment by 3232 community respondents in 18 nations were investigated at the local, national, and global spatial levels. These assessments were compared to a ranking of each country's environmental quality by an expert panel. Temporal pessimism (“things will get worse”) was found in the assessments at all three spatial levels. Spatial optimism bias (“things are better here than there”) was found in the assessments of current environmental conditions in 15 of 18 countries, but not in the assessments of the future. All countries except one exhibited temporal pessimism, but significant differences between them were common. Evaluations of current environmental conditions also differed by country. Citizens' assessments of current conditions, and the degree of comparative optimism, were strongly correlated with the expert panel's assessments of national environmental quality. Aside from the value of understanding global trends in environmental assessments, the results have important implications for environmental policy and risk management strategies.     

Early action to reduce greenhouse gas emissions before the commitment period of the Kyoto protocol: advantages and disadvantages

Current “business as usual” projections suggest greenhouse gas emissions from industrialized nations will grow substantially over the next decade. However, if it comes into force, the Kyoto Protocol will require industrialized nations to reduce emissions to an average of 5% below 1990 levels in the 2008–2012 period. Taking early action to close this gap has a number of advantages. It reduces the risks of passing thresholds that trigger climate change “surprises.” Early action also increases future generations' ability to choose greater levels of climate protection, and it leads to faster reductions of other pollutants. From an economic sense, early action is important because it allows shifts to less carbon-intensive technologies during the course of normal capital stock turnover. Moreover, many options for emission reduction have negative costs, and thus are economically worthwhile, because of paybacks in energy costs, healthcare costs, and other benefits. Finally, early emission reductions enhance the probability of successful ratification and lower the risk of noncompliance with the protocol. We discuss policy approaches for the period prior to 2008. Disadvantages of the current proposals for Credit for Early Action are the possibility of adverse selection due to problematic baseline calculation methods as well as the distributionary impacts of allocating a part of the emissions budget already before 2008. One simple policy without drawbacks is the so-called baseline protection, which removes the disincentive to early action due to the expectation that businesses may, in the future, receive emission rights in proportion to past emissions. It is particularly important to adopt policies that shift investment in long-lived capital stock towards less carbon-intensive technologies and to encourage innovation and technology development that will reduce future compliance costs.     

Environmental Guidelines for Power Plants in India and Other Nations

The emissions guidelines for power plants in India are comparable to those of many other developed and developing nations, and in some cases are more stringent. But India's environmental impact assessment and enforcement practices need to be improved. © 2001 John Wiley & Sons, Inc.     

Calculating the cost of greenhouse gas emission reductions (heading into kyoto protocol negotiations in Buenos Aires)

Negotiations toward an international regime to control anthropogenic emissions of greenhouse gases have been under way for more than a decade. The Kyoto Protocol¹ to the United Nations Framework Convention on Climate Change (FCCC)² reflects a basic intergovernmental agreement that predicted warming and volatile weather events are sufficient threats to justify mandatory measures. Yet with climate change negotiations set to resume November 2 through 13, 1998, in Buenos Aires, Argentina, at the Fourth Session of the Conference of the Parties (COP-4), many major industries continue to believe that the disproportionate costs of controls will precipitate severe economic consequences, and that mandatory measures may never actually be implemented, or at least will be deferred for many years. This article examines why some business decision makers and their environmental managers remain unwilling or unable to make concrete plans to achieve the significant reductions that the Kyoto Protocol facially requires. Indeed, there has been surprising inattention at the boardroom and plant levels to the concepts and details of the agreement. This is reinforced to some extent by the apparently dim prospects for ratification in the near term by the U.S. Senate, in which the treaty today would likely not gain a majority, much less the necessary two-thirds support.     

Material efficiency: A white paper

For most materials used to provide buildings, infrastructure, equipment and products, global stocks are still sufficient to meet anticipated demand, but the environmental impacts of materials production and processing, particularly those related to energy, are rapidly becoming critical. These impacts can be ameliorated to some extent by the ongoing pursuit of efficiencies within existing processes, but demand is anticipated to double in the next 40 years, and this will lead to an unacceptable increase in overall impacts unless the total requirement for material production and processing is reduced. This is the goal of material efficiency, and this paper aims to stimulate interest in the area. Four major strategies for reducing material demand through material efficiency are discussed: longer-lasting products; modularisation and remanufacturing; component re-use; designing products with less material. In industrialised nations, these strategies have had little attention, because of economic, regulatory and social barriers, which are each examined. However, evidence from waste management and the pursuit of energy efficiency suggests that these barriers might be overcome, and an outline of potential mechanisms for change is given. In bringing together insights into material efficiency from a wide range of disciplines, the paper presents a set of 20 open questions for future work.
