Do people have a negative impression of government on polluted days? Evidence from Chinese Cities

Chinese governments play a key role in providing environmental public goods. Urban air quality is a significant indicator with which people evaluate the effects of governments’ environmental regulations and investments. This study aims to investigate how people's impression of government varies with air pollution in Chinese cities. Using the Baidu online search index on the specific keyword ‘corruption’ to represent public attitude toward the government, our estimations show that an increase in air pollution level yields a significant increase in online searches on this word. Such an effect is more significant on heavily polluted or severely polluted days. In further estimations, we find that people will not pay more attention to the polluters themselves on polluted days. These results are consistent with previous studies that air pollution causes people to be more depressed, selfish and sensitive to fairness. We conclude that efforts on air quality improvement will create a positive impression of government.

Overview of Environmental Hazards and Health Effects of Pollution in Developing Countries: A Case Study of Nigeria

Pollution has taken on a global dimension, and the effects are most obvious in developing countries. The effects take a toll on human health, animals, and vegetation, as well as on soil, air, and water quality. The objective of this article is to discuss the current relationships among pollution, environmental quality, and human health within the frame of anthropogenic activities in developing countries. In addition to personal observations, we review relevant literature on conditions throughout the developing world and case studies on conditions and activities in Nigeria. Key findings show the significant, adverse contributions to human health and environmental risk from current waste generation and handling practices, indoor and outdoor air pollution, wastewater and effluent generation and disposal, the hazardous nature and pollution potential of wastes, and the human behaviors that contribute to pollution in developing countries. There is an urgent need to create awareness among the various segments of society of the human health hazards posed by pollution as well as a need for the comprehensive development and enforcement of appropriate policies to prevent a descent into an abyss of deteriorating human and environmental health.     

Industry's role in air quality improvement: Environmental management opportunities for the 21st century

More than 200 years ago, Adam Smith, the founder of modern economics, wrote in the Wealth of Nations that “…consumption is the sole end and purpose of all production; and the interest of the producer ought to be attention to…that of the consumer.” In recent years, the rapid growth of the world economy has given Adam Smith's maxim new meaning. The age-old desire for consumption grows unabated and increasing numbers of consumers around the world are attaching new value to the environmental quality of goods and services and expressing concern over the environmental impacts of industrialization. That concern is growing because more than 70 percent of the world's urban population live in areas where the air is seriously polluted and as many as 750,000 people—the majority in developing countries—die each year of ailments caused by air pollution.¹ Over the past 25 years, corporations throughout the world have made dramatic changes in the way they do business as more people come to understand how the ecological system works and how polluted air and water endanger human health. The key to increasing industry's participation in the drive for higher standards of air quality is the growing realization that effective environmental management, technological development, and technology dissemination are cost-effective and profitable business strategies. Global competition is making firms around the world more customer-conscious and, to the extent that consumers demand products that minimize environmental degradation and enhance the quality of their lives, businesses in every industry must respond in order to survive.² This article examines how changes in business practices, driven by a better understanding of how natural environments function, are converging to provide new opportunities for environmental management that go beyond regulatory compliance to reduce air pollution. Although sound and well-enforced environmental regulations are an essential foundation for improving air quality, command-and-control systems alone are unlikely to achieve the lower levels of pollution that will be necessary to achieve sustainable development in the 21st century. In cooperation with government, businesses in every industry can play crucial roles in achieving higher standards of air quality while at the same time maintaining acceptable levels of economic growth. We explore three ways in which corporations can contribute to environmentally sustainable development: (1) by adopting proactive environmental management systems that focus on air pollution prevention; (2) by developing new technologies for air pollution control and reduction; and (3) by transferring air pollution control and prevention technologies through international trade and investment.

一个政府—企业双层优化环境治理模型

构建以政府为主导、企业为主体的环境治理体系，落实企业环境治理主体责任是我国的重大战略任务。目前地方政府环境监管亟待改善，需要加强企业生产规制，基于"污染者付费"原则促使"三废"达标排放。本研究抓住政府和企业两大主体，建立以政府为上层、企业为下层的双层优化环境治理模型，确定上层-下层目标函数及约束条件，研究地方政府环境奖罚政策与企业利润及环境行为的关联性，提出模型"乐观最优解"与"悲观最优解"及地方政府奖惩机制最优解。该模型可反映地方政府与企业的博弈过程，为寻求合理的污染奖惩方式和税费比例，促使企业在自身利润最大化的同时积极治理"三废"污染，平衡经济效益和社会效益，为企业长期粗放式生产排污严重、地方政府环境监管有待加强、西北生态安全屏障和黄河流域健康发展受到严重威胁的宁蒙沿黄地带及类似地区环境管理实践提供参考。     

Passive Samplers for NOx Monitoring: A Critical Review

Nitrogen oxide is an important gaseous air pollutant. It plays a major role in atmospheric chemistry, particularly in the formation of secondary air pollutants such as ozone, peroxyacyl nitrate (PAN), nitrate aerosols, and contributes to environmental acidification. A comprehensive assessment of NO₂ levels in the atmosphere is required for developing effective strategies for control of air pollution and improvement of air quality. Consequently, spatial NO₂ monitoring has become an important aspect of air quality assessment. Present NO₂ monitoring networks are mostly confined to urban areas, having a limited number of monitoring sites. Wide spatial NO₂ monitoring in India is constrained because of the limited availability of the monitoring equipment, such as continuous chemiluminesence monitors, high volume and handy samplers, which are expensive and need to be imported. Moreover, they require elaborate infrastructure, scientific personnel, technical support and uninterrupted power supply. In an effort to overcome the above shortcomings, passive samplers have been successfully used for large scale monitoring of NO₂ in the ambient environment.In recent years, passive samplers have been gaining increasing attention because they are simple, lightweight and cheap devices, which operate without any power source. Passive samplers have been found to be efficient, cost effective and free from the need for elaborate calibration and maintenance. Hence, they are ideally suited for developing a wide spatial network for NO₂ monitoring. This paper presents a comprehensive review including, historical development and critical assessment of validation studies along with comparison of both badge and tube type passive samplers. An attempt has been also made to highlight advantages and limitations, as well as discussion on the factors affecting the efficiency of passive samplers under field conditions.     

美国环境与健康管理体制借鉴

美国为应对环境污染带来的公共健康灾难,建立了环保局与卫生部既分工又协作的体制,两个部门都关注环境污染对人类健康的危害。在职能上,环保局侧重于管制和"污染者",卫生部侧重于服务和"潜在受害者"。联邦层面,环保局与卫生部在管制方面和研究(信息共享)方面紧密合作。地方层面,环保局的主要职能是监督各州执行联邦标准,卫生部的主要职能是提供健康和医疗服务,并在具体工作中密切配合。借鉴美国的经验教训,明确建立"公众健康优先"的环境管理价值取向,针对环境与健康风险管理的特点推进生态环境统一监管机构改革,以法治思维和法治方法推进环境与健康治理体系建设;加强科学研究,加快建设环境与健康风险控制信息系统。

Design for environment: A new framework for strategic decisions

For most of its history of environmental protection, U.S. policy has concentrated on a pollution control strategy based on single medium emissions: air, water, or land. Efforts to mitigate environmental impacts to one medium often resulted in greater impacts to others. While much environmental improvement has occurred via this system over the last quarter-century, it is generally recognized that alternative strategies which address environmental impacts across all media in an integrated manner will be necessary for continued improvement. Increasingly, regulatory strategies that result in only passive compliance will be insufficient to meet these demands. This article demonstrates why new strategies which encourage proactive behavior are necessary. A new framework for making strategic decisions—design for environment—concerning the relation between our actions and environment is necessary to ensure a sustainable future.     

The case against free market environmentalism

Free market environmentalists believe that the extension of private property rights and market transactions is sufficient to address environmental difficulties. But there is no invisible hand operating in markets that ensures that environmentally sound practices will be employed just because property rights are in private hands. Also, liability laws and the court systems cannot be relied upon to force polluters to internalize the social costs of pollution. Third, market prices do not provide an objective measure of environmental matters. Finally, there is a right to a livable environment that justifies regulations protecting the public from unreasonable environmental risks.

基于模糊数学的大气环境质量综合评价

鉴于大气环境质量评价中客观存在的不确定性和模糊性,运用模糊数学方法,选用SO2、NO2、PM10作为评价因子,参照大气环境质量标准,通过计算污染因子权重分配系数和隶属度对乌鲁木齐市2004年至2010年大气环境质量给出客观的评价,综合评价结果表明乌鲁木齐市总体大气环境质量为轻度污染(三级),但空气质量在逐年好转,SO2和PM10依然是乌鲁木齐市空气质量的制约因子,且NO2的权重在逐年上升。模糊综合评判考虑环境空气质量评价的模糊性,根据污染物浓度对各级别的贴近度考察污染物的级别,评价结果比较直观,可以细致准确的评价环境质量等级,评价结果基本可以反映环境空气污染的情况。     

Review and challenges of policies of environmental protection and sustainable development in China

China is confronted with the dual task of developing its national economy and protecting its ecological environment. Since the 1980s, China's policies on environmental protection and sustainable development have experienced five changes: (1) progression from the adoption of environmental protection as a basic state policy to the adoption of sustainable development strategy; (2) changing focus from pollution control to ecological conservation equally; (3) shifting from end-of-pipe treatment to source control; (4) moving from point source treatment to regional environmental governance; and (5) a turn away from administrative management-based approaches and towards a legal means and economic instruments-based approach. Since 1992, China has set down sustainable development as a basic national strategy. However, environmental pollution and ecological degradation in China have continued to be serious problems and have inflicted great damage on the economy and quality of life. The beginning of the 21st century is a critical juncture for China's efforts towards sustaining rapid economic development, intensifying environmental protection efforts, and curbing ecological degradation. As the largest developing country, China's policies on environmental protection and sustainable development will be of primary importance not only for China, but also the world. Realizing a completely well-off society by the year 2020 is seen as a crucial task by the Chinese government and an important goal for China's economic development in the new century, however, attaining it would require a four-fold increase over China's year 2000 GDP. Therefore, speeding up economic development is a major mission during the next two decades and doing so will bring great challenges in controlling depletion of natural resources and environmental pollution. By taking a critical look at the development of Chinese environmental policy, we try to determine how best to coordinate the relationship between the environment and the economy in order to improve quality of life and the sustainability of China's resources and environment. Examples of important measures include: adjustment of economic structure, reform of energy policy, development of environmental industry, pollution prevention and ecological conservation, capacity building, and international cooperation and public participation.     

Environmental Management: Testing the Win‐Win Model

The debate over the possibility of seeking competitive advantages through greener strategies versus the scarcity of such opportunities is not yet resolved. This study is an attempt to test the win-win model. The role of the variables at the core of the win-win model, such as the regulatory factors, environmental strategy and environmental innovativeness, was examined. The results validated the positive competitive and financial impact of progressive environmental strategies contingent upon the presence of favourable external and internal conditions. From purely a profitability standpoint, it is important to seek a balance between the environmental measures and market expectations. Comprehensive superiority in relative environmental performance will not necessarily lead to environmental competitive advantage.
