Chevron Corp., headquartered in San Francisco, manages a worldwide, vertically integrated value chain from the oil well to the gasoline station. Mishandling of oil at any stage of production can damage the natural environment, human health, corporate profitability, or all three. But at the same time Chevron needs to be prudent about the amount of money it spends on measures to manage these risks, and environmental programs within the firm can conflict with a long-standing tradition of decentralized management. To manage risks more efficiently, Chevron executives are contemplating the use of quantitative decision tools that enable operating managers to compute rough benefit-cost ratios for various alternative risk management projects. The case focuses on the pros and cons of using such tools within the context of Chevron's overall system for environmental risk management.

Political demands for environmental improvement create obligations for managers that can conflict with shareholder value creation. While differentiating products along environmental lines is a conceptually straightforward way of reconciling these apparently conflicting demands, not all attempts to do so have succeeded. This article describes three requirements for successful environmental product differentiation: 1) firms must discover or create a willingness in consumers to pay for public goods; 2) they must overcome barriers to the dissemination of credible information about the environmental attributes of their products; and 3) they must defend themselves against imitation. More broadly, environmental strategy must be integrated with the overall strategy of the business. The appropriate environmental strategy depends, like the business's overall strategy, on the fundamental economics of the industry and the business's internal capabilities--basic constraints that have often been obscured in the academic debate about business and the environment.

Set in November 1993. Intended as a follow-up to the (A) case.

Set in April 1990, this case focuses on H.J. Heinz and its subsidiary, StarKist, the largest producer of canned tuna in the United States. During the 1980s, the public became increasingly concerned about tuna fishing practices that killed dolphins. StarKist was the target of a consumer boycott initiated by the environmental community. Worried that bad publicity from the boycott would threaten the StarKist brand name, as well as Heinz's other branded products, senior management at Heinz decided that StarKist would become the first tuna processor to no longer purchase tuna caught by methods that killed dolphins. In making the decision, Heinz executives were not sure how StarKist's two major competitors would react, or how the decision would impact the procurement of raw tuna, StarKist's single largest expense item. Discusses the harvesting (fishing) and processing (canning) sector of the tuna industry. Also discusses the Marine Mammal Protection Act, and U.S. trade sanctions against Mexico and other countries.

Reading Energy builds facilities that produce energy from nontraditional fuels. A privately held, entrepreneurial organization, it has spent six years developing a plan to build a waste-to-energy plant in the town of Robbins, Illinois. The plant would burn municipal solid waste, producing electricity for sale to the local utility. Its economics are driven by the cost of alternative waste disposal technologies (mostly landfills) and by the Public Regulatory Policy Act of 1978, which ensures a market for the power. Reading's project has been delayed by political opposition at both the local and state levels. Robbins is a poor community, and some of Reading's antagonists have invoked environmental justice as a reason to oppose the project. Tom Cassel, the engineer who founded Reading, is negotiating contracts for waste with nearby municipalities. He needs to consider price, risk allocation, and other economic factors, in addition to political and social issues, in designing his firm's strategy and tactics.

Addresses contingent environmental liabilities that are the result of unforeseen environmental risks where the dollar amount of such liabilities is unknown and depends on future events. In contrast, fines for violating environmental laws are liabilities, but are not considered contingent liabilities as such fines are relatively predictable. Covers liabilities under common law doctrines (including toxic torts), the Resource Conservation and Recovery Act (RCA), and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). In particular, discusses lender liability issues as of 1993 and briefly discusses financial reporting requirements. Concludes with a discussion of strategies for managing such liabilities.

Introduces students to the arithmetic of the accounting for national productivity growth. It defines labor productivity, capital productivity, and total factor productivity, describes the relationships among them, and discusses the phenomena that cause them to change over time. Exhibits include data for the United States and other industrial countries, which both show the relationships among the various measures and allow comparison across time and space. The end of the note discusses the 1992 controversy over productivity growth in Singapore. Productivity is an important phenomenon, widely discussed in the newspapers, but rarely even defined. Business students, especially those engaged in country analysis, need to understand the various ways in which it is measured and why those various quantities have changed over time in different nations. Intended for an introductory MBA course.

During the 1990s, environmental activists became interested in trade issues for the first time. Whereas GATT, the General Agreement on Tariffs and Trade, had previously been the province of trade specialists, a new poster popular among environmentalists depicted the monster "GATTzilla," devouring the earth, dolphins, and democratic institutions. This case describes the conflict between environmental and trade values as it is manifested in various multilateral institutions and treaties: GATT, especially after its controversial ruling on a United States dolphin protection law; NAFTA, the North America Free Trade Agreement, for which environmental matters have become an unexpected stumbling block; the European Community, as it tries to harmonize member regulations; and multilateral treaties such as CITES (the convention on trade in endangered species), the Montreal Protocol on ozone-depleting substances, and attempts to protect tropical timber.

Since winning independence in 1965, Singapore achieved some of the world's highest rates of economic growth. A large part of GDP and employment came from direct investment by multinational companies in low-cost assembly work, but in the 1990s Singapore's rising wage rates increasingly priced it out of these industries. Could Singapore change itself from an assembler and fabricator of Western-designed parts to a designer and marketer of desirable products? Lee Kuan Yew, "the father of Singapore," repeatedly had shown an ability to guide the nation through such transitions. Not only did his successor have no such track record, but the next transition might be the hardest yet.

In addition to the issues of expected cost minimization elucidated in Acid Rain: The Southern Co. (A), problems involving regulatory uncertainty are critical to the firm's Clean Air Act compliance strategy. The regulatory uncertainty affects, and is affected by, the uncertainties about the price of allowances to emit sulfur dioxide. Provides additional information on the regulatory risks and uncertainties confronting the Southern Co.; permits exploration of the relations between federal environmental regulation and state-level regulation of rates of return.

The governments of Malaysia and the Malaysian State of Sarawak need to assess possible changes in forest policy. Environmentalist pressure threatens traditional market relationships and patterns of business-government interaction. Harvest regulations, subsidies, trade restrictions, environmental controls, and property rights structures are all called into question.

The Southern Co., an electric utility, is planning its compliance with the 1990 amendments to the Clean Air Act. The Act established a system of tradeable permits for sulfur dioxide emissions. The company must decide whether to install pollution control equipment and generate excess permits for sale to other firms, or to emit larger quantities of sulfur dioxide, save capital costs, and purchase pollution permits. Can be used to teach discounted cash flow analysis of a make versus buy decision. Also raises issues of expected cost minimization, questions of economic and political uncertainty, and the value of flexibility.

Burlington Northern (BN) hauls low-sulfur coal from the northern Great Plains to electric utilities in the Midwest. Acid rain legislation may affect the geographic scope of BN's markets. Railroad managers need to assess the economic effects of acid rain controls and their chances of influencing the controls' structure.

Describes the Bush administration clean air bill of 1989 and other legislative proposals.

Champion's forest products division owns timberlands, sawmills, and plywood mills in the Pacific Northwest. The listing of the northern spotted owl as an endangered species, and restrictions on exports of logs from state-owned lands, have disrupted the stumpage, log and product markets in which Champion competes. Tag Edwards, executive V.P. for forest products, needs to decide how to respond to these regulatory changes, using economic data and political information.

Supplements the (A) case.

In 1988, the Du Pont Co. is abruptly confronted with solid scientific evidence that chlorofluorocarbons are destroying the earth's ozone shield. Du Pont, with its Freon brand product line serving markets for foam insulation, electronics solvents, and especially refrigeration, was the world's leading producer of these chemicals. Although no substitutes were currently commercially available, or even proven, Du Pont had to decide what to do. The purpose of the case is to examine how changing science and environmental problems affect competitive conditions and corporate strategy. In particular, the case examines the criteria by which companies formulate policy.
