Nanotechnology Oversight: An Agenda for the New Administration

Identifies how current laws can be applied or modified to provide needed oversight of nanotechnology and materials for public health and environmental protection. Calls for more funding for risk research, coordinated regulation, and public involvement

Regulating Government

Federal, state, and local governments are major polluters of the environment. They account for more than 7% of SO2 air pollution emissions and more than 5% of all NO2 air emissions in the United States. Public entities are more likely than private ones to be in violation of the Clean Water Act, and they account for two-thirds of all major facilities in significant noncompliance with the act. Department of Energy nuclear sites are the worst hazardous waste problems in the nation. A lack of adequate data makes it difficult to fully characterize the extent of pollution caused by government agencies and to compare the performance of the public and private sectors. There are many reasons why government pollution is difficult to regulate. The paper discusses political dimensions, legal problems, resource constraints, psychological dimensions, and public opinion. Further research is urgently needed, and the paper delineates areas that require more investigation.pollution control, federal facilities, regulation, intergovernmental relations

Environmental Implications of the Foodservice and Food Retail Industries

The growing size and importance of service sector industries in the U.S. economy raises questions about the suitability of the current environmental management system to deal with perhaps a changing set of environmental concerns. This paper analyzes the environmental impacts associated with the activities undertaken and influenced by two service sector industries—foodservice (e.g., restaurants) and food retail (e.g., grocery stores). This paper is not a definitive analysis of the magnitude of the environmental effects of these industries, but is intended to be a comprehensive survey of the types of environmental implications—positive and negative—of these two service sectors. The foodservice and food retail industries are components of a larger industrial system, the food marketing system, that extends from the production of food to the marketing of food products to consumers. The U.S. foodservice industry comprises an estimated 831,000 individual establishments, employs an estimated 11 million people (about 8.6% of the U.S. workforce), and is expected to have total sales of $376 billion in 2000. The U.S. food retail industry encompasses approximately 126,000 grocery stores, employs approximately 3.5 million people (about 2.7$449 billion in 1998. For this analysis, we use a simple conceptual framework that segregates the environmental impacts of these industries into three categories: direct, upstream, and downstream. We conclude that, while the direct environmental impacts (e.g., energy use, solid waste generation; air and water emissions; food safety concerns; refrigerants) of these industries are important to recognize and address, opportunities also exist for these industries to address their upstream and downstream environmental impacts.

Environmental Implications of the Health Care Service Sector

This report analyzes the environmental effects associated with activities undertaken and influenced by the health care service sector. It is one part of a larger study to better understand the environmental effects of service sector activities and the implications for management strategies. Considerable analysis has documented the service sector's contribution to domestic economic conditions, yet little analysis has been performed on the broad impacts service firms have on environmental quality. For this study the authors developed a framework to examine the nature of service sector industries' influence on environmental quality. Three primary types of influence were identified: direct impacts, upstream impacts, and downstream impacts. In addition, indirect impacts induced by service sector activities include their influence over settlement patterns and indirect influences over other sectors of the economy. In their initial analysis, the authors noted that many functions performed in the service sector also are commonly found in other sectors. The impacts of these activities have been analyzed separately from those unique to the health care sector, as they present different challenges. Health care is one of the largest U.S. industries, employing one in nine workers and costing one in seven dollars generated in the economy. Functions performed in the industry that are common in other sectors include: transportation; laundry; food services; facility cleaning; heating and cooling; and photographic processing. Activities unique to the health care industry include: infectious waste generation and disposal; medical waste incineration; equipment sterilization; dental fillings; ritual mercury usage; x-ray diagnosis; nuclear medicine; pharmaceutical usage and disposal; and drinking water fluoridation. The industry has considerable leverage upstream on its suppliers, which is important to managing risks from the use of goods commonly used in the industry, including: mercury-containing products, polyvinyl chloride plastics, latex gloves, and syringe needles. The authors identified a number of areas for potential environmental management initiatives: controlling emissions from on-site "production" type functions; mercury use; the environmental consequences of infection control measures; pollution prevention through substitution of alternative health care services; and research and data collection.

Environmental Priorities for the District of Columbia: A Report to the Summit Fund

This paper examines and ranks the District of Columbia's environmental problems. Four criteria are used to determine each problem's severity: public opinion of the problem, health effects, the number of people affected, and ecological and welfare effects. Public opinion is measured via 345 city resident and 23 stakeholder interviews. Stakeholders included environmental experts familiar with issues in the District. Health and ecological effects are captured by analyzing both the EPA's and District of Columbia's environmental data. The results show that the top four problems facing the city, in order of importance, are: drinking water, air pollution, the Anacostia River, and lead poisoning. Several recommendations for resolving the District's problems are offered and including creating a separate D.C. Environmental Agency, applying for EPA grant monies, publishing a D.C. environmental report, fostering community cooperation, and increasing education about the environment.

Entrepreneurs, Chance, and the Deterministic Concentration of Wealth

In many economies, wealth is strikingly concentrated. Entrepreneurs–individuals with ownership in for-profit enterprises–comprise a large portion of the wealthiest individuals, and their behavior may help explain patterns in the national distribution of wealth. Entrepreneurs are less diversified and more heavily invested in their own companies than is commonly assumed in economic models. We present an intentionally simplified individual-based model of wealth generation among entrepreneurs to assess the role of chance and determinism in the distribution of wealth. We demonstrate that chance alone, combined with the deterministic effects of compounding returns, can lead to unlimited concentration of wealth, such that the percentage of all wealth owned by a few entrepreneurs eventually approaches 100%. Specifically, concentration of wealth results when the rate of return on investment varies by entrepreneur and by time. This result is robust to inclusion of realities such as differing skill among entrepreneurs. The most likely overall growth rate of the economy decreases as businesses become less diverse, suggesting that high concentrations of wealth may adversely affect a country's economic growth. We show that a tax on large inherited fortunes, applied to a small portion of the most fortunate in the population, can efficiently arrest the concentration of wealth at intermediate levels
