| Chapter 9: Environmental 			 Economics   You can't have a healthy economy 				without a healthy environment. We need not choose between breathing clean air 				and bringing home secure paychecks. The fact is, our environmental problems 				result not from robust growth, but from reckless growth. The fact is that only 				a prosperous society can have the confidence and the means to protect its 				environment. And the fact is healthy communities and environmentally sound 				products and services do best in today's economic competition.   President Bill Clinton   In 1993 the nexus between the economy and the environment was 				never more clear. Continued economic growth is based on the availability of 				material and energy resources and an environment that is clean and healthy. 				Protecting the natural environment requires a nation to be flexible, to make 				tradeoffs-a fundamental tenant of economics-and to recognize the benefits and 				costs of the choices made.   Markets are shaped by consumer's choices of goods and services 				and producer's choices of inputs. Although the market price of a product 				indicates its worth to consumers, the price of use of natural resources does 				not always have a monetary value that can be as easily quantified. Because the 				nation values the benefits provided by the environment, and is now 				acknowledging the costs associated with loss of environmental amenities, the 				federal government and the American people as a whole have taken action to 				protect the environment and continue on this path.  Conditions and Trends
  In addition to environmental cost accounting, major trends in 				1993 included a growing interest in sustainable development and in using an 				ecosystem approach to management as a way to achieve it.  Reinventing Environmental Management: Cost 				Accounting
  In September 1993 the National Performance Review issued an 				accompanying report entitled, Reinventing Environmental Management, that calls 				for improved federal decisionmaking through environmental cost accounting. The 				NPR recommended the following actions:   The EPA, DOD, and OMB should develop pilot programs to 				demonstrate the use of environmental cost accounting by the federal government. 				The report calls for the EPA and the DOD Office of the Deputy Under Secretary 				for Environmental Security, in consultation with the OMB, to convene an 				interagency working group with the following responsibilities:   . Develop demonstration projects to test the applicability and 				effectiveness of environmental cost accounting in the federal government; and 				  . Formulate accounting guidelines for the demonstration projects. 				  The Environmental Cost Accounting Working Group should report on 				the demonstration projects and make recommendations on the use of environmental 				cost accounting in the federal government. The NPR calls for the interagency 				working group to report results of the projects and recommendations on the 				extent to which environmental cost accounting could be implemented throughout 				the federal government.   The President should issue a directive to implement 				environmental cost accounting in the federal government. Based on the 				recommended guidelines from the interagency working group, the President should 				issue a directive to agencies to incorporate environmental cost accounting into 				the appropriate decisionmaking processes.  Sustainable Development
  Sustainable development offers an opportunity to gauge the 				relationship between economic development and environmental protection. The 				1987 report of the World Commission on Environment and Development (the 				Brundtland Commission) defines sustainable development as that which -meets the 				needs of the present generation without compromising the ability of future 				generations to meet their own needs.- Sustainable development ensures that 				future generations have access to the -social capital---human, natural, and 				physical capital-to create a life at least equal to that of this generation. 				Similarly, the National Environmental Policy Act declares that it is the 				continuing policy of the Federal Government to create and maintain conditions 				under which man and nature can exist in productive harmony and fulfil the 				social economic and other requirements of present and future generations.   Economic growth is a driving force for improved welfare and 				environmental quality. An improvement in either the environment or the economy 				need not be at the expense of the other. Since the aim of sustainable 				development is to achieve an equilibrium between economic and environmental 				resources to enable future generations to enjoy a standard of living at least 				equivalent to ours, improved methods for calculating the value of environmental 				resources are required. To meet the challenge of sustainable development, the 				federal government continued in 1993 to seek ways to integrate environmental, 				economic, and social policies to reduce the cost, reduce the conflict, and reap 				the benefits of environmental protection.  President's Council On Sustainable 				Development
  Established by Executive Order 12852 on June 29, 1993, the 				President's Council On Sustainable Development is a 25-member partnership of 				high-ranking representatives from industry, government, environmental, labor 				and civil rights organizations. The partnership is charged with developing bold 				new approaches to integrate economic and environmental policies. By charter the 				Council shall have the following duties:   . Advise the President on matters involving sustainable 				development. In furtherance of the mission, the Council will develop and 				recommend to the President a national sustainable development action strategy 				to foster economic vitality.   . Advise the President on fashioning an annual Presidential Award 				  recognizing exemplary efforts in advancing sustainable 				development ideals; submit nominations for the award to the President.   . Advise the President on conducting a public awareness and 				participation campaign on appropriate uses of the nation's natural and cultural 				resources.  Expenditures and Revenues
  The EPA estimates that U.S. public and private sector costs for 				1993 pollution abatement and control were $123.7 billion. The estimated 				distribution of costs among economic sectors in 1993 revealed that private 				industry had the greatest total share (62 percent), followed by local 				governments (22 percent), the federal government (13 percent) and state 				government (3 percent). Of total U.S. expenditures, $67 billion (54 percent) 				were associated with operating, maintenance, and administrative expenses, and 				the remaining $57 billion (46 percent) reflected the annual depreciation of the 				stock of pollution control capital equipment.  Flow of Materials
  The potential value of recycling materials that today are 				discarded as wastes has implications for the environment and the economy. 				Wastes are a byproduct of delivery and consumption of four basic commodities 				that support modern society: food, water, energy, and materials a catch-all 				term for everything else. The nation uses renewable and nonrenewable resources 				to manufacture materials. Forestry and agricultural products, for example, 				provide renewable materials, and minerals and fossil fuels provide nonrenewable 				materials. The use of these materials to manufacture the goods that have become 				an essential part of modern society-machines, housing, roads, cars, packaging, 				and other consumer products has increased over the years.   Material input to the U.S. economy in 1990 provides a snapshot of 				current material use patterns on a weight basis and their implications for 				environmental risk. Trends in material usage reflect historical consumption and 				recycling patterns. Of the 2.5 billion metric tons of materials consumed by the 				nation, only 10 percent were recycled. Without changes in technology, the 				quantity of residuals or waste produced increases directly in relation to 				material use. Three critical issues relate to this equation:   . Potential resource scarcity;   . The limited capacity of the environment to absorb residuals; 				and   . Environmental hazards associated with toxic residuals.   Of the 487 million metric tons of residuals released to the 				environment, excluding associated water or nonmineralized waste, 57 percent was 				post-consumer waste, 28 percent was waste from dissipated uses with limited 				potential for recovery, and 15 percent was processing waste.   As material flows increase, the waste products from extraction, 				processing, use, and ultimate disposal of materials also increase. A 				combination of change in industry practice, economic incentives, new technology 				development, shift in material use, and change in consumer behavior will change 				the growing residuals-producing trend. If not, current environmental problems 				will worsen unless the ability of the environment to absorb waste is increased 				with better and more costly methods of solid waste disposal.   Construction Materials. Construction minerals such as 				stone and gravel represented the nation's largest material use, with 1.8 				billion metric tons or 70 percent of total U.S. apparent consumption. Of these 				minerals 7.8 percent were recycled. Of the total residual waste, 235 million 				metric tons or 48 percent were from construction materials released into the 				environment. These materials are essentially extracted and used without any 				change in their chemical composition and are associated with visibility, noise, 				and dust. Most of the residuals are post-consumer waste (135 million tons or 58 				percent); processing creates 63 million metric tons; and dissipative use 				creates 37 million metric tons of residuals.   Industrial Minerals. Consumption of industrial minerals, 				such as those used to produce fertilizer and road salt, totaled 330 million 				metric tons, with 7.6 percent from recycled materials. Release of industrial 				mineral residuals totaled 129 million metric tons. Although these materials 				undergo processing that can alter physical and chemical properties and 				concentrations, they create a relatively small amount of processing waste (5 				million metric tons). Most of the waste is related to dissipative uses (98 				million metric tons), followed by post-consumer releases (26 million metric 				tons). Some commodities in this group are harmful to the environment such as 				cadmium, asbestos, fertilizers, and road salt.   Metals. Consumption of metals amounted to 112 million 				metric tons, but 54 percent were recycled materials. Residuals released to the 				environment by metal extraction and processing totaled 20 million metric tons. 				For several commodities in this group, releases associated with the processing 				and manufacturing phase and, to a lesser extent, post-consumer waste are cause 				for concern. Although not included in the residuals total, extraction waste 				near mining locations can cause environmental problems.   Plastics. The use of organic feedstocks to create plastic 				is growing rapidly and has created concern about the increasing volume of 				material in municipal landfills. Furthermore, plastics contain additives, such 				as colorants, stabilizers, and plasticizers, that may contain toxic 				constituents such as cadmium and lead; plastics contribute 28 percent of all 				cadmium found in municipal waste and approximately 2 percent of all lead. 				Plastics that contain heavy metal-based additives may contribute to the metal 				content of incinerator ash. Some feedstock producers are establishing 				collection networks and secondary markets that could improve recycling rates. 				Because only 2 percent of plastics are recycled, virtually all of these 				materials are landfilled or incinerated.   Renewable Organics. The total for renewable organic 				material consumption was 231 million metric tons, including wood products such 				as lumber and paper and nonfood agricultural products such as tobacco, 				vegetable oils, and cotton. Of these 8 percent were recycled materials. 				Residuals of renewable organics amounted to 80 million metric tons. Dissipative 				use represented 1.2 percent of the total, while post-consumer waste represented 				99 percent. Renewable organics create environmental problems with the large 				quantity of paper in the post-consumer wastestream and the process wastes, 				including chemical releases, associated with papermaking. Other than wood pulp 				and tobacco, renewable organics do not create significant environmental 				problems.   Nonrenewable Organics. Consumption of nonrenewable organic 				materials derived from petroleum and natural gas, such as plastics, synthetic 				rubber, asphalt, and manmade textiles, totaled 113 million metric tons, with 				only 2.7 percent produced from recycled materials. Residuals from post-consumer 				waste totaled 21 million metric tons. Extraction wastes are generally low, but 				processing and manufacturing wastes can create local environmental problems. 				Data on the amount of releases during these stages are incomplete.   Animal Products. Consumption of nonfood animal products, 				such as leather and furs, was the lowest of all groups at 2 million metric 				tons, of which only 1 percent were recycled. Residuals nearly equaled the 				quantity of apparent consumption (2 million metric tons), with most residuals 				associated with dissipative uses. Processing waste discharged was 20,000 metric 				tons, and post-consumer waste, another 50,000 metric tons. These materials are 				renewable and normally biodegradable.  International Trade and the Environment
  Among the growing number and scope of international activities 				concerned with environmental protection policies, a subject of increasing 				attention is the relationship of environmental policies and practice to 				international trade.   Federal Policymaking. In the United States, a number of federal 				departments and agencies, including the Office of the U.S. Trade Representative 				(USTR), State Department, Environmental Protection Agency, and the departments 				of Commerce, Treasury, Agriculture, Labor, Interior, Energy, and Health and 				Human Services, participate in trade environmental policymaking. Together these 				federal agencies are seeking to develop information to better understand the 				linkages between trade and the environment and to make trade and environmental 				policies compatible with sustainable development.   International Dialogues. The United States is actively 				participating in a number of international dialogues regarding trade and the 				environment, including the new World Trade Organization, Committee on Trade and 				the Environment; the Organization for Economic Cooperation and Development 				(OECD), Trade and Environment Joint Experts Committee; and the United Nations 				Environment Program/United Nations Commission on Trade and Development 				(UNEP/UNCTAD) joint work program on trade and environment.   Trade in Environmental Protection Equipment. A 1993 EPA 				report entitled International Trade in Environmental Protection Equipment: 				An Assessment of Existing Data, estimates total U.S. imports, exports, and 				trade balances for environmental protection equipment between 1980 and 1992. 				Estimates include trade levels in environmental protection equipment for air, 				water, and other environmental media. The EPA also examined bilateral trade 				flows between the United States and selected U.S. trading partners. The report 				found that the United States is a major exporter of environmental protection 				equipment, in general, and of air pollution control equipment in particular. 				Only 21 percent of the air pollution control equipment sold in the United 				States is supplied by imports. The United States enjoyed a surplus of trade in 				environmental equipment for all purposes of $1.1 billion in 1991, and this 				surplus has been increasing since 1989. Between 1989 and 1991, U.S. exports 				increased approximately 70 percent, while imports increased 45 percent. The 				nation has been operating positive trade balances with most of its major 				trading partners in environmental protection equipment since 1989. The largest 				surpluses in 1991 were held with Canada and Japan.  U.S. exports, imports, and trade balance for environmental

Program Accomplishments In 1993 the federal government made progress in establishing 				methods of environmental accounting and valuation to characterize the benefits 				provided by the environment. A major component has been the recognition in 				recent years of the value of ecosystems.  Environmental Accounting and Valuation
  In 1993 the EPA continued to support the work of the Ecological 				Economic Forum, a group of ecologists, economists, and other social scientists 				that began meeting in 1991 to advance the state of the art of ecosystem 				valuation methods. The deliberations of this forum led to recommendations for 				integrated research as a means to improve linkages between ecological and 				economic methods and to develop improved protocols for valuation studies.   The EPA has initiated a case study of the Patuxent River 				watershed in Maryland, intended to contribute to the general development of 				integrated ecological-economic modeling. The research will develop methods for 				valuing ecosystem configurations and services from them. The effort seeks to 				model the interaction of the ecosystem and human activity, illustrating how 				humans intervene in the ecosystem and how different ecosystem configurations 				contribute to human welfare.  Environmental Accounting
  In 1993 the Bureau of Economic Analysis prepared modified gross 				domestic product (GDP) national income and product accounts for publication in 				1994. Prepared with support from the National Biological Survey in the 				Department of the Interior, these accounts reflect the depletion of selected 				natural resources and also the -discovery- of natural resources as a result of 				exploration. The national income and product accounts, designed to help 				government agencies interpret the processes that produce current income and 				future wealth, have been used as a tool for policy analysis for the last 50 				years. In this regard incorporating elements of the environment into the 				national accounting framework will improve the quality of the accounts and the 				policy options available.   The EPA is exploring methods to introduce environmental 				considerations into conventional economic accounting systems. A pilot study of 				environmental accounting in the Chesapeake Bay region was conducted by the EPA 				and reviewed by the Science Advisory Board's Environmental Economics Advisory 				Committee (EEAC). Based on the EEAC review of the study, the EPA published a 				report evaluating the potential of environmental accounting to capture 				environmental concerns, as well as the difficulties in such an exercise in 				1993. EPA environmental accounting work will focus on the approach proposed in 				the draft handbook on Integrated Environmental and Economic Accounting prepared 				by the United Nations Statistical Office. In particular the EPA is 				investigating the feasibility of expanding an ongoing economic input-output 				(I-O) study of environmental protection activities to include environmental 				measures such as air and water discharges. The I-O study follows protocols 				defined by the Department of Commerce and is used to measure who buys and sells 				goods and services from whom within defined industrial and governmental sectors 				found throughout the economy. The introduction of air and water discharges 				would make more explicit the non-priced economic service the environment 				provides as a result of its ability to assimilate pollutant discharges allowed 				under existing air and water permits. IF this approach is deemed feasible and 				reasonable, the EPA will develop set of environmental accounts using this 				framework.  Harnessing Market Forces
  The nation has achieved considerable progress in protecting 				natural resources and the environment as the result of establishing 				environmental standards and regulations. Prior to passage of U.S. environmental 				laws, the absence of ownership of these public goods contributed to the decline 				in environmental quality. The development of standards succeeded in making more 				explicit the costs to the environment of human activity.   Much of the early environmental legislation and policies focused 				on developing standards and dictating engineering solutions to rectify the most 				obvious environmental hazards. Many of these environmental improvements led 				consumers and producers to invest in environmental pollution controls. The 				early emphasis on command-and-control solutions to environmental problems, 				while in many ways successful in achieving environmental goals, has proved to 				be expensive. Furthermore, many environmental problems do not easily lend 				themselves to these same control measures. The complexity of controlling large 				numbers of dispersed pollution sources demands that alternative policies and 				economic tools be used to resolve these issues.   The federal government has moved to adopt more market-based 				incentives and other economic tools to help reduce the costs associated with 				environmental requirements. For example, using a market-based approach, the 				government specifies an environmental goal, such as a 50-percent reduction in 				emissions of a given compound within a geographic area, and then provides 				flexibility to the industry in choosing how to meet that goal in the most 				cost-effective manner.   As a result of these efforts, market-based incentives have moved 				from relative obscurity to a tool for improving the environment while departing 				from -command and control- regulations and sometimes offering opportunities to 				reduce cost. The 1990 Clean Air Act amendments has led the EPA to propose and 				promulgate incentive-based mechanisms for the control of acid rain, for the 				development of cleaner burning gasoline and less polluting vehicles, for states 				to use in controlling urban ozone and carbon monoxide, and to facilitate the 				reduction of toxic air emissions.   As other key environmental statutes-are up for reauthorization, 				incentive mechanisms promise to be actively considered as environmental 				legislative proposals make their way through Congress. The EPA is preparing 				analysis of numerous possible incentives to support this dialogue. Some states 				have implemented incentive programs, and others are considering such proposals. 				  The evidence on the environmental effects of economic incentives, 				while much less extensive than that on economic efficiency, suggests that 				incentive mechanisms are fully compatible with environmental objectives (see 				the incentives table, which describes different types of incentive instruments, 				some of which are further distinguished on the basis of when the incentive 				becomes effective). Incentives can establish a system of rewards for innovation 				through a variety of specific mechanisms. Some incentive mechanisms establish 				prices indirectly through market transactions. Within this group are 				information reporting requirements, such as Title III of the Superfund 				Amendments and Reauthorization Act. Others, such as pollution fees and various 				trading systems, including the EPA air emission trading program, transferrable 				development rights, and marketable effluent discharge credits, are other types 				of incentives.   Some new systems as yet not fully implemented hold out 				considerable promise for being both effective and efficient in reducing 				pollution. Beverage container deposits appear to have greatly reduced litter, 				but limited knowledge is available on the impact of other deposit-refund 				systems and virtually no analysis of the costs and benefits of any of the 				deposit-refund mechanisms is available.   As in the United States, official interest in economic incentives 				appears to be increasing in Europe. A review of the use of economic incentives 				outside the United States suggests a preference for a somewhat different mix of 				incentive mechanisms. The United States uses many more marketable permit 				systems than do European countries, but much less environmental labeling. 				Although charges and fees are used more widely in Europe, they tend to be 				revenue-raising instruments with few incentive impacts, just as in the United 				States. The lack of incentive impact of charges is due primarily to their low 				magnitude and because a number of the charges are not closely linked to waste 				generation or product consumption.  Trading Systems
  In 1993 the Administration's National Performance Review 				identified the use of market systems as a tool to further investigate for 				achieving environmental standards in a cost-effective manner. Among the set of 				market-based tools, trading systems have drawn the greatest overall attention 				of environmental managers.   Although all trading programs require some involvement of a 				pollution control agency, the extent of that involvement varies substantially. 				The nature of the pollutants being controlled and the production practices of 				the firms being regulated serve to steer which types of trading are feasible. 				Besides these factors a number of general conditions can be used to 				differentiate among trading programs (see attributes table).   For example, trading programs can occur among different firms or 				different parts of an individual firm's production operations-both of which 				could take into account matters of quantity and timing of emissions. Trading 				among firms is often used to take advantage of relative cost efficiencies that 				may arise as a consequence of new, cleaner technologies not uniformly adopted 				by firms, such as an acid rain trading program. Trading within a firm's 				production process allows the firm to target those steps in the production 				process that can be modified to reduce emissions, or similarly, to select 				cost-effective solutions involving a number of processes in those cases where 				multiple outputs are produced, such as the steel industry effluent bubble.   Another factor in operating a trading program involves whether 				mass emissions limits are required. Mass emission limits prescribe the total 				emissions that a polluter may emit over a designated period of time. Issues 				concerning such limits include setting a baseline, the nature of the pollutant 				such as bioaccumulative and transport properties, accurate emissions 				monitoring, and defining penalties provisions that are limit-related. The 				geographic area for which trades are permitted is largely determined by the 				type of pollutant. If the pollutant spreads widely and has adverse effects at 				the low concentrations found at distant points, the geographic area is likely 				to be large, such as chlorofluorocarbons. Other pollutants such as wood stove 				emissions may have adverse effects primarily on a small local or regional area. 				  Most published studies on the subject have been based upon exante 				analysis of costs and anticipated market behavior. Because of the potential 				impacts nationwide of acid rain and climate change, the EPA is committed to 				assessing the cost savings of trading programs. The objective is to provide 				further empirical evidence of the efficacy of trading as a means of reducing 				the cost of environmental protection.  Environmental Concerns and Innercity Economics
  The EPA is forging partnerships with other federal agencies and 				departments to provide innercity residents and minority businesses with 				opportunities connected to eliminating environmental hazards in their 				communities. Partnerships assist in carrying out the federal commitment to use 				programs and activities to advance environmental protection in urban 				communities. These programs also create minority business entrepreneurial 				opportunities, job training, and placement by stimulating economic growth and 				development in the community. Innercity problems such as substandard water and 				air quality, toxics in the home (lead, asbestos, and indoor air pollution), and 				energy conservation are of paramount concern at the community, municipal, 				state, and federal levels.   The EPA Office of Environmental Equity (OEE) is sponsoring 				Community Economic Development Projects such as the following:   Mercado Project. An OEE training grant funds the 				California State University at Hayward to prepare a business management 				training program and business plan for its Mercado Project in the 				Asian-American community in the San Francisco Bay area. The project is 				developing a public education center and small business incubator for retail 				outlets and related manufacturing, such as assembly facilities of 				high-value-added products made using secondary materials as a feedstock. The 				project will train and employ diverse members of the community who would be 				less likely to have these entrepreneurial and job opportunities without such 				training and business development. Unemployed residents will learn to convert 				recyclable woods and plastics into furniture that can be sold to provide 				revenue for the community.   District of Columbia Lead Abatement. A memorandum of 				agreement among the EPA, departments of Housing and Urban Development and 				Commerce, and the District of Columbia has led to a project that trains 				unemployed residents of D.C. public housing units in lead paint remediation and 				abatement. Once trained and certified, the District has pledged to hire workers 				to start on remediating lead from the units. The partnership will help 				residents interested in forming their own small businesses or link them with 				existing small businesses. Any companies formed will be eligible for 				noncompetitive contracts through the HUD Title 3 program. In a closed system, 				residents are trained, certified, and hired to clean up their communities- own 				environments to reduce lead exposure and improve environmental quality in their 				neighborhood. The project could serve as a model for other urban areas with 				lead problems.   Hazardous Waste Management Technicians. The EPA Superfund 				Office is funding Cuyahoga Community College in Ohio to train unemployed 				residents as hazardous waste management technicians. Private industries in the 				area have agreed to employ trained residents in local cleanup efforts. The 				Cuyahoga project offers residents the option of working toward Associate of 				Arts degrees or of enrolling in 4-year degrees at a consortium college.   Xavier University Study. The EPA Office of Small and 				Disadvantaged Business Utilization (OSDBU) provided $115,000 of Clean Air Funds 				to Xavier University, a historically black university in New Orleans, 				Louisiana, to study clean air issues affecting small and disadvantaged 				businesses in small communities along a corridor with high incidence of cancer. 				Study results will provide the residents of these communities with a Plan of 				Action to determine their environmental needs. The OSDBU is evaluating other 				economic development initiatives to provide minority communities additional 				opportunities to participate in the environmental marketplace.  REFERENCES
