Quantifying the human health benefits of curbing air pollution in Shanghai

Urban development in the mega-cities of Asia has caused detrimental effects on the human health of its inhabitants through air pollution. However, averting these health damages by investing in clean energy and industrial technologies and measures can be expensive. Many cities do not have the capital to make such investments or may prefer to invest that capital elsewhere. In this article, we examine the city of Shanghai, China, and perform an illustrative cost/benefit analysis of air pollution control. Between 1995 and 2020 we expect that Shanghai will continue to grow rapidly. Increased demands for energy will cause increased use of fossil fuels and increased emissions of air pollutants. In this work, we examine emissions of particles smaller than 10 microm in diameter (PM10), which have been associated with inhalation health effects. We hypothesize the establishment of a new technology strategy for coal-fired power generation after 2010 and a new industrial coal-use policy. The health benefits of pollution reduction are compared with the investment costs for the new strategies. The study shows that the benefit-to-cost ratio is in the range of 1-5 for the power-sector initiative and 2-15 for the industrial-sector initiative. Thus, there appear to be considerable net benefits for these strategies, which could be very large depending on the valuation of health effects in China today and in the future. This study therefore provides economic grounds for supporting investments in air pollution control in developing cities like Shanghai.     

Policy formulation for the management of hazardous pollutants

Hazardous pollutants pose a number of distinct problems for the public policy maker, most notably because of the uncertainty surrounding the effects of such pollutants and the potentially serious or irreversible outcomes of hazardous pollution damage. Policy approaches to the problem have generally used some kind of balancing approach—between costs and benefits, or between risks and benefits. Direct controls such as standards or bans are the most commonly used policy instruments in dealing with hazardous pollutants due to the certainty of outcome which they provide. However, many more regulatory options are available to the public policy maker, for example, economic incentives and legal procedures.     

Food Supply Chain Governance And Public Health Externalities: Upstream Policy Interventions And The UK State

Contemporary food supply chains are generating externalities with high economic and social costs, notably in public health terms through the rise in diet-related non-communicable disease. The UK State is developing policy strategies to tackle these public health problems alongside intergovernmental responses. However, the governance of food supply chains is conducted by, and across, both private and public spheres and within a multilevel framework. The realities of contemporary food governance are that private interests are key drivers of food supply chains and have institutionalized a great deal of standards-setting and quality, notably from their locations in the downstream and midstream sectors. The UK State is designing some downstream and some midstream interventions to ameliorate the public health impacts of current food consumption patterns in England. The UK State has not addressed upstream interventions towards public health diet at the primary food production and processing stages, although traditionally it has shaped agricultural policy. Within the realities of contemporary multilevel governance, the UK State must act within the contexts set by the international regimes of the Common Agricultural Policy and the World Trade Organization agreements, notably on agriculture. The potential for further upstream agricultural policy reform is considered as part of a wider policy approach to address the public health externalities issuing from contemporary food supply chains within this multilevel governance context.     

Economic Evaluation of Carbon Dioxide Emission Abatement Measures in the Greek Energy Sector

This paper outlines a methodological framework for the economic evaluation of carbon dioxide (CO 2 ) emission abatement policies and measures, formulating a basis for the selection of those options of climate change mitigation interventions that minimize economic cost and maximize social welfare. To this purpose, a cost-benefit analysis has been implemented in order to evaluate a variety of CO 2 emission abatement measures in the Greek energy sector on the basis of their social (i.e. the sum of the private and external) costs and benefits, and it is compared with a cost-effectiveness analysis, which takes into account only the net financial costs of the examined interventions. The analysis clearly reveals that a significant decrease in CO 2 emissions is possible without great cost to the economy. Moreover, the monetization of environmental benefits (e.g. the restriction of impacts on human health, agriculture and biodiversity, etc.) associated with the above-mentioned interventions represents a powerful tool for highlighting priority actions in the context of a climate change mitigation policy and for quantifying their overall economic and environmental effectiveness.     

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.     

Mitigating Industrial Pollution Along the Atlantic Coast of Cameroon: An Overview of Government Efforts

Summary This paper presents an overview of the initiatives that have been formulated by the government of Cameroon to address the problem of industrial pollution. It also prescribes robust recommendations that could be employed to save the Atlantic coast of Cameroon from industrial pollutants. After the participation of Cameroon in the Earth Summit in Rio de Janeiro in 1992, the government took a significant step to overhaul its institutional framework, legal framework and policy framework vis-à-vis the regulation of industrial pollution. Under the auspices of the United Nation Industrial Development Organisation (UNIDO), the Gulf of Guinea Large Marine Ecosystem Project aimed at sustaining the health of the Atlantic coast of Cameroon by ensuring treatment of industrial wastes, oil spills, sewage and heavy metals was implemented (1995–1999). Based upon careful analysis, however, the paper argues that these efforts have had little or no discernable impacts and that industrial activities along the Atlantic coast of Cameroon are still a major threat to safety, health and the environment. With a considerable number of hurdles that still persist, sufficient environmental improvement in industrial pollution along the Atlantic coast of Cameroon is far-fetched. Nevertheless, the paper concludes that marked environmental improvement can be obtained if: (i) competent personnel are appointed in ministries that play an active role in mitigating industrial pollution (ii) research partnerships are forged with local universities (iii) industrial machinery and equipment are improved (iv) inter institutional conflicts are addressed (v) a more collaborative forum between stakeholders is established (vi) adequate monitoring is instituted. The provisions of this paper form the foundation of an ongoing research being conducted by the authors at Brandenburg University of Technology, Cottbus, Germany.     

The benefits and costs of reducing emissions from the electricity sector

Recent federal policy proposals to reduce emissions of sulfur dioxide (SO(2)), nitrogen oxides (NO(x)), and mercury from the US electricity sector promise important improvements in air quality and reductions in acid deposition. The cost of achieving these reductions depends on the form and stringency of the regulation. In this research, we analyze the economic benefits and costs of the US Environmental Protection Agency's (EPA's) Clean Air Interstate Rule (CAIR) as characterized in the supplemental rule proposed in June 2004, and the Clean Air Mercury Rule (CAMR) as proposed in February 2004. The assessment integrates a model of the electricity sector, two models of atmospheric transport of air pollutants, and a model of environmental and public health endpoints affected by pollution. We model explicitly the emissions of SO(2), NO(x), mercury and carbon dioxide (CO(2)) and the effects of changes in emissions of SO(2) and NO(x) on environmental and public health. The manner in which mercury emissions are regulated will have important implications not only for the cost of the regulation, but also for emission levels for SO(2) and NO(x) and where those emissions are located. We find the economic benefits of CAIR and CAMR are far greater than the costs. Recent estimates of benefits of reductions in mercury and acidification indicate that our model captures the lion's share of quantifiable benefits. We also find that the EPA would have been justified on economic grounds in pursuing additional SO(2) emissions reductions beyond the requirements of CAIR.     

Packaging waste and the polluter pays principle: a taxation solution

Packaging waste has become a focus for attention by policy‐makers in a number of countries. This article offers a simple policy measure — a packaging tax or levy — which serves the required aims of policy, namely: reducing waste at source; increasing the rate of recycling; and consistency with the polluter pays principle. The tax is illustrated in the context of beverage containers in the UK and Japan. The merits of the proposal are its simplicity and flexibility. The article suggests that the relevant environmental damages are captured by waste disposal costs and litter. Other life cycle impacts, such as emissions from energy use, could be included but only if there are not more efficient ways of regulating them.

An integrated model for technology forecasting to reduce pollutant emission in China's pulp industry

The Chinese government has been implementing a strict pollutants gross control policy during the 11th Five Year Plan period. Primary pollutants reduction (COD & SO₂) is one of the major concerns of industrial environmental management. This paper constructs a technology selection model for industrial pollutants reduction by incorporating mass flow analysis of the production system, bottom-up modeling methodology, and linear programming for optimizing annualized discounted cost. A case study of COD emission control is carried out on the Chinese pulp industry, the nation's leading source of industrial COD discharge. The model is used to generate and analyze the technology prospects and COD emission situations under various scenarios for 2010, 2020 and 2030.     

Continuing Issues in the Limitations of Pesticide Use in Developing Countries

The rationale for pesticide use in agriculture is that costs associated with pesticide pollution are to be justified by its benefits, but this is not so obvious. Valuing the benefits by simple economic analysis has increased pesticide use in agriculture and consequently produced pesticide-induced “public ills.” This paper attempts to explore the research gaps of the economic and social consequences of pesticide use in developing countries, particularly with an example of Nepal. We argue that although the negative sides of agricultural development, for example- soil, water, and air pollution; pest resistance and resurgence; bioaccumulation, bio-magnification; and loss of biodiversity and ecosystem resilience caused by the use of pesticides in agriculture, are “developmental problems” and are “unintentional,” the magnitude may be increased by undervaluing the problems in the analysis of its economic returns. Despite continuous effort for holistic system analyses for studying complex phenomena like pesticides impacts, the development within the academic science has proceeded in the opposite direction that might have accelerated marginalization of the third world subsistence agricultural communities. We hypothesize that, if these adversities are realized and accounted for, the benefits from the current use of pesticides could be outweighed by the costs of pollution and ill human health. This paper also illustrates different pathways and mechanisms for marginalization. In view of potential and overall negative impacts of pesticide use, we recommend alternative ways of controlling pests such as community integrated pest management (IPM) along with education and training activities. Such measures are likely to reduce the health and environmental costs of pesticide pollution, and also enhance the capabilities of third world agricultural communities in terms of knowledge, decision making, innovation, and policy change.     

Comparative analysis of air pollution emissions by electric utilities: Public policy implications

One of the objectives of US environmental regulations was to reduce industrial air pollution emissions, especially from the electric utility industry, the major industrial air polluter. In this study, a comparative analysis of air pollution emissions from fossil-fuel-burning electric utility plants is conducted. The analysis focuses on a 12-yr period from 1975 to 1987 for three air pollutants: particulates, surfur dioxide, and nitrogen oxides. The results indicate that particulate emissions have been significantly reduced but that sulfur dioxide and nitrogen oxides are still major problems for a number of plants. Furthermore, the disparity in the performance by plants indicates that by using current technology, the industry as a whole could greatly reduce these emissions. These results have policy implication for future environmental legislation.     

DISTRIBUTIONAL ISSUES IN WESTERN MUNICIPAL AND INDUSTRIAL WATER SUPPLY1

ABSTRACT Financing and repayment provisions of western water projects effect transfers of income among federal taxpayers, electric power users, local water users, and property owners. We use the Bonneville Unit of the Central Utah Project as a case study in the distribution of municipal and industrial water costs. We examine the distribution of costs among taxpayers and water users in different political/geographical jurisdictions, and how this distribution is affected by water law, cost allocation procedures, and the choice of revenue source for local repayment of reimbursable costs. In light of the magnitude of distributional effects of present water policy, we conclude that lack of open debate on water issues is unfortunate. We conclude with speculation on the relationship of western water policy to the motivation of western water leaders who are instrumental in its formulation     

Particulate and lead air pollution control in Cairo: benefits valuation and cost-effective control strategies

Recent research has suggested that health damage from air pollution—most notably from inhalable particulate matter and lead—is a serious concern in many cities in developing countries. A comparative risk assessment conducted in Cairo in 1994 found these two pollutants to be especially worrisome, and an analysis of the potential economic benefits associated with controlling these pollutants suggests that their economic damage is significant. Control strategies to reduce ambient pollutant levels are under development, with point source controls on major industrial facilities—especially in the secondary lead smelling industry—a cost-effective initial step.     

CO2 emissions reduction from the power system in India

The power system in India accounts for nearly one-third of CO₂ emissions of the country as a whole. A comparison of some of the technical options to reduce CO₂ emissions is presented in this paper. A linear programming framework is used to simulate the integrated optimal operation of the three regional grids, and it is shown that such operations lead to lower fuel costs and to lower CO₂ emissions. The same framework is used to see how a rise in thermal efficiency translates into a CO₂ emissions reduction. Reduced fuel requirements also lead to reductions in other pollutants ie SO₂, NO_x and fly ash. The reductions in CO₂ emissions and other pollutants are at far lower cost in the case of integrated optimal operations as compared to reductions due to gas fuelled generation or thermal efficiency improvements. However, thermal efficiency improvements under optimal integrated operations result in much higher reductions in operating costs, coal consumption and total emissions of all pollutants.     

Where Did the Agricultural Nonpoint Source Trades Go? Lessons from Virginia Water Quality Trading Programs

Governmental agencies, nongovernmental organizations, and agricultural organizations promote water quality trading programs as an innovative policy to engage agricultural producers in conservation activities. Cost analyses suggest regulated sources can reduce compliance costs by purchasing agricultural nonpoint source credits. Yet, such “point‐nonpoint” trades are rare. This article assesses the demand for agricultural nonpoint sources in well‐developed nutrient trading programs in Virginia for industrial and municipal wastewater treatment plants, municipal stormwater programs, and land developers. Evidence suggests nutrient trading programs in Virginia will not stimulate investments in pollutant reduction practices on working agricultural lands. The lack of demand for agricultural nonpoint source credits can be attributed to a substantial degree to the design features and incentives present in multiple overlapping regulatory programs. The legal setting that dampens regulated source demand for nonpoint source credits in Virginia is broadly representative of conditions found elsewhere in the United States.     

EFFECT OF WATER QUALITY STANDARDS ON FARM INCOME,RISK, AND NPS POLLUTION1

ABSTRACT: Enforceable standards play a crucial role in the design and implementation of most water quality policies. The impacts of these standards on farm income and nonpoint source (NPS) pollution can provide valuable information to develop economic policies that can improve water quality with minimal loss in income and minimal risk. This study uses an integration of nonlinear programming and a simulation model to assess the impacts of enforceable standards at technology and farm boundary levels. The results indicate that the type of pollutant regulated, enforcement type, and the level of standard had a significant impact on farm income and water quality. Choice of farm boundary standards over technology standards is dependent on the impact of the policy on other NPS pollutants, in addition to the reduction of nitrate and phosphorus pollutants. Enforcing farm boundary standards on nitrates had desirable effects on subsurface and percolate nitrogen and variance in income. Technology standards were uncertain in their effects because of the restriction on the choice of technologies available to farmers. A comparative policy analysis considering incentives, multiple impacts, transaction costs of implementation, and regional consideration is important to an effective policy design.

Managing agricultural emissions to the atmosphere: state of the science, fate and mitigation, and identifying research gaps

The impact of agriculture on regional air quality creates significant challenges to sustainability of food supplies and to the quality of national resources. Agricultural emissions to the atmosphere can lead to many nuisances, such as smog, haze, or offensive odors. They can also create more serious effects on human or environmental health, such as those posed by pesticides and other toxic industrial pollutants. It is recognized that deterioration of the atmosphere is undesirable, but the short- and long-term impacts of specific agricultural activities on air quality are not well known or understood. These concerns led to the organization of the 2009 American Chemical Society Symposium titled . An outcome of this symposium is this special collection of 14 research papers focusing on various issues associated with production agriculture and its effect on air quality. Topics included emissions from animal feeding operations, odors, volatile organic compounds, pesticides, mitigation, modeling, and risk assessment. These papers provide new research insights, identify gaps in current knowledge, and recommend important future research directions. As the scientific community gains a better understanding of the relationships between anthropogenic activities and their effects on environmental systems, technological advances should enable a reduction in adverse consequences on the environment.
