Reaching environmental decisions: Making subjective and objective judgments

Objective judgments, external to the judge, are compared with subjective, internal judgments. This analysis is made in the context of reaching regulatory decisions affecting the human environment. Examples given include evaluating the potential risk of industrial chemicals and comparing the potential effects of short- and long-term changes in land use. The analysis deals not with the decisions themselves, but rather with the kinds of questions that must be posed in orderto reach such decisions. Decision makers may spuriously distinguish objective from subjective types of judgment, though these are rarely wholly separate. Judges can hardly dispute about objective statements, if truly identical definitions are used. But subjective statements can reasonably be voted upon. Scientists, engineers, and economists represent logical or objective decision makers, tending to work in groups. Subjective thinkers include artists and performers, and others who often work alone. Moral and aesthetic aspects of questions, usually seen as intangible, are treated as if subjective. Financial decisions, usually viewed as tangible, are handled as objective problems. This mechanism for making decisions is well-established in environmental assessment. Though objective questions can be treated well in the monetary terms of cost-benefit analysis, subjective ones cannot. Mathematical and other variants are discussed in relation to the comparison of alternative types of tests.     

Making decisions about environmental management when conventional economic analysis cannot be used

A process is described for making comparative valuations of a wide range of environmental management activities when the combined social, economic, managerial, and political benefits of some (but not all) of these activities cannot be adequately described in economic terms and when budgetary constraints do not permit funding of all activities under consideration. The process accounts for subjective judgment and contains a formal rigorous decision strategy that takes the place of intuition when quantitative and qualitative values of environmental activities need to be evaluated.     

Supporting multi-stakeholder environmental decisions

This paper examines how multiple criteria analysis (MCA) can be used to support multi-stakeholder environmental management decisions. It presents a study through which 48 stakeholders from environmental, primary production and community interest groups used MCA to prioritise 30 environmental management problems in the Mackay-Whitsunday region of Queensland, Australia. The MCA model, with procedures for aggregating multi-stakeholder output, was used to inform a final decision on the priority of the region's environmental management problems. The result was used in the region's environmental management plan as required under Australia's Natural Heritage Trust programme. The study shows how relatively simple MCA methods can help stakeholders make group decisions, even when they hold strongly conflicting preferences.     

Levels of environmental decisions

The language of decision theory is used to model the perspectives of two parties in the management of an environmental hazard. These are (a) individuals whose homes are polluted by radon by-products which thereby pose an uncertain health hazard and (b) the public authorities concerned about those individuals' welfare. The analysis provides a way of anticipating ways in which the perceptions and decisions of these parties are intertwined, as well as how they can come into conflict. It also suggests ways in which these difficulties might be ameliorated by altering the respective decision problems. The heuristic value of modeling decision problems in other contexts is discussed, with brief consideration of the substantive issues arising with acid rain and seatbelt usage.     

Cutting the cake: Supporting environmental fund allocation decisions

This paper describes a decision support model for allocating financial resources amongst multiple user groups in environmental management problems. The model is based on the multiple criteria analysis (MCA) method of compromise programming. It was used to inform the allocation of Natural Heritage Trust funds across 14 regions in Queensland, Australia. The model targets funding to those regions with greater natural resource management needs. Need is determined by 19 weighted criteria relating to natural resource assets and threats. The model was accepted by the Australian Government, Queensland Government and regional groups as an appropriate means for allocating program funds; first in 2005 and then again, with improvements, in 2007. This paper shows that an MCA model can improve the transparency, auditability and acceptance of allocation decisions which would otherwise be heavily politicised.     

Enduring decisions: Evaluating environmental impacts for sustainability planning

This paper aims to establish a framework in which potential methods for evaluating environmental impacts can be considered, with particular reference to the UK planning system. To do this a number of complementary ways of conceptualising sustainable development and making it more practical are outlined. Some basic arguments about the meaning of sustainability are reviewed; and some common misconceptions about the concept exposed. The concept of sustainability constraints is outlined and a functional distinction between quantitative and qualitative constraints is proposed. The adoption of sustainability constraints based on measures of environmental capacity is proposed. These suggest significant reductions in consumption of most environmental resources. The efficiency and sufficiency strategies that would be needed to meet the proposed quantified constraints are outlined. In conclusion, evaluation processes and indicators of sustainability, including environmental foot-printing and environmental impact assessment, are discussed, offering some pointers towards the type of measures that will be needed to help implement sustainability strategies.     

Use of value functions in environmental decisions

Value functions are devices that allow discrete analyses of environmental impacts to be reconciled to a single quantitative scale of preference. The values obtained can then be weighted and combined into measures of the relative desirability of policy alternatives. However, for this methodology to be valid, the set of impacts used must satisfy a number of conditions; and whether or not these are met depends on how the impacts are selected and characterized. This paper generalizes instances where the conditions may be violated and how they may be resolved, and concludes with a few thoughts on how the methodology might be adapted to the routine of bureaucracy.This work was performed under the auspices of the U.S. Department of Energy by the Lawrence Livermore Laboratory under Contract W-7405-ENG-48.     

Making sense of environmental accounting

Much as Total Quality Management (TQM) has helped companies decrease waste and enhance value, environmental accounting offers an approach and a suite of tools that can help organizations improve both environmental quality and bottom-line business performance. Its focus is to bridge the world of finance and economics with the world of environmental management. Companies in all sectors have discovered that they can increase profits by meeting and even surpassing environmental regulations. Through environmental accounting, companies can discover more of these opportunities and, ideally, bring environmental concerns earlier into planning, decision making, and operations. This article introduces environmental accounting and some basic principles that should guide organizations' thinking on environmental accounting and environmental accounting systems. It also describes several different objectives for environmental accounting that imply different requirements and orientations. Although the focus of this article is on environmental accounting as an aspect of forward-looking management and decision making in companies, much of the discussion applies to nonprofits and government units as well.     

Structure and function of environmental programmes

Summary In this article, the need for integrated curricula in environmental science/studies programmes is reviewed. The required competencies/outcomes for understanding and solution of environmental problems, the requirement for interdisciplinarity and incorporation of innovative skills/methods into environmental curricula, examples of ways to integrate curricula, teaching methodologies and their rationales, impacts of environmental programmes, and academic support for programmes, are also examined in this context.Dr John Lemons is Professor of Biology and Environmental Science, and Chairperson of the Department of Life Sciences at the University of New England. He is also Editor-in-Chief ofThe Environmental Professional, the official journal of the National Association for Environmental Professionals.     

The effects of perceived conflict,resource scarcity,and information bias on emotions and environmental decisions

The failure to anticipate the public's response to environmental problems can lead to expensive delays, bad public relations, and litigation, as well as environmental decisions that do not represent public values and preferences. This study examines the influence of conflict between management goals, perceived resource scarcity, and information bias on evaluations of the importance of management goals; the perception of conflicts among the goals; and the emotions evoked in an urban forest management problem. Environmental problem scenarios were systematically manipulated as to the level of conflict between development and natural preservation goals, the scarcity of urban nature, and the bias of the presented information. Evaluations of the importance of urban nature and economic development were susceptible to manipulations of scarcity. The importance of urban nature was also higher when information was biased toward pro-preservation issues. Negative emotions were associated with high conflict and scarcity and with the propreservation information bias. Both evaluations of goal importance and conflict among goals appeared to be based on an underlying economics-versus-amenity dimension. These results are similar to previous studies of environmental decision making with regard to nonurban environmental problems. This research offers a beginning in understanding and anticipating the way members of the public may respond to information about environmental problems.     

Integrated environmental management: strengthening the conceptualization

Although espoused by many, integrated environmental management (IEM) has been difficult to accomplish in practice. There are many reasons for this shortfall, but certainly a key factor is the lack of agreement among scholars and practitioners regarding the concept and its defining elements. Our purpose here is to sharpen the conceptual basis for IEM by elaborating and pragmatically characterizing a framework for the practice of more integrated environmental management. We outline four fundamental dimensions of IEM: (1) comprehensive, (2) interconnective, (3) strategic, and (4) interactive/coordinative. IEM efforts in the Black Earth Creek watershed in Wisconsin illustrate specific attributes and examples pertaining to our conceptualization of IEM. Acceptance of the conceptual framework elaborated here should alleviate some of the confusion associated with IEM and help move this widely heralded approach from theory into practice.     

Setting rational environmental goals: Five Swedish environmental quality objectives

Goals and performance targets are commonly used as tools in the policy-implementation process. In Sweden, environmental policy is operationalized through a system of environmental quality objectives that were adopted by the Swedish Riksdag in the late 1990s. The objectives describe what level of environmental quality Sweden should aim for within a generation, and are designed to guide decision making in all sectors of society. However, to guide decision making toward improved environmental quality, these objectives should satisfy a set of rationality (functionality) criteria; they should be precise, evaluable, approachable, motivating and coherent. In this paper, five Swedish environmental quality objectives are investigated through an application of the suggested criteria: (1) a balanced marine environment, flourishing coastal areas and archipelagos; (2) a magnificent mountain landscape; (3) a non-toxic environment; (4) natural acidification only; and (5) a good built environment. The aim of the paper is to bring the rationality of the objectives up for discussion, and to illustrate the range of issues and difficulties that are involved in choosing and assessing environmental policy goals.     

Business-oriented environmental performance metrics: Building consensus for environmental management systems

Today, environmental managers are learning new ways of adding value to their organizations. Before, the environmental department was an overhead expense—an indirect support group required for complying with burdensome regulations. Now, such departments add insights and value during strategic planning sessions, identify efficiency improvement opportunities, provide a superior return on investment, and—bottom line—improve profits. The primary approach to meeting the challenge is a new environmental management system (EMS) that identifies, measures, and manages a diverse set of internal and external customer needs. These needs include environmental cleanups, regulatory compliance, pollution prevention, and design for the environment—and each represents a potential improvement opportunity. Unfortunately, most organizations have so many such needs that all cannot be addressed at once, given the resource constraints of a competitive business climate. Thus, priority is a key concept of an effective EMS. This article describes an innovative application of consensus-building tools that quickly identify and set priorities for diverse environmental programs. The article also shows how appropriate performance measures will align these programs with corporate goals and objectives.     

Derivative mine valuation: strategic investment decisions in competitive markets

Successful management in competitive markets requires evaluation methods that respond to global market dynamics and provide investors with relevant information to make strategic investment decisions. These strategic decisions include decisions on investment timing, feasibility study and risk management and mine operating options. Conventional methods do not have the built-in capabilities to help investors handle these strategic issues. Advances in modern finance have had profound impacts on financial markets for options, futures and collaterized securities and offer appropriate tools in solving these problems. In this paper, the authors have extended the Brennan and Schwartz mineral resource model to develop the derivative mine valuation method based on the dynamic arbitrage theory. A copper mining venture has been evaluated using the derivative mine valuation and conventional methods. The results show that the derivative mine valuation method allows investors to maximize the venture's market value by exercising these strategic options.
