The precautionary principle has often been described as an extreme principle that neglects science and stifles innovation. However, such an interpretation has no support in the official definitions of the principle that have been adopted by the European Union and by the signatories of international treaties on environmental protection. In these documents, the precautionary principle is a guideline specifying how to deal with certain types of scientific uncertainty. In this contribution, this approach to the precautionary principle is explicated with the (...) help of concepts from the philosophy of science and comparisons with general notions of practical rationality. Three major problems in its application are discussed, and it is concluded that to serve its purpose, the precautionary principle has to (1) be combined with other decision principles in cases with competing top priorities, (2) be based on the current state of science, which requires procedures for scientific updates, and (3) exclude potential dangers whose plausibility is too low to trigger meaningful precautionary action.

The Precautionary Principle is both celebrated and criticized. It has become an important principle for decision making, but it is also subject to criticism. One problem that is often pointed out with the principle is that is not clear what it actually says and how to use it. I have taken on this problem by performing an analysis of some of the most influential formulations of the principle in an attempt to identify the core ideas behind it, with the purpose (...) of producing a formulation of the principle that is clear and practically applicable. It was found that what is called the Precautionary Principle is not a principle that tells us what do to achieve extra precaution or how to handle situations when extra precaution is called for. Instead, it was found to be a list of circumstances that each justify extra precaution. An analysis of some of the most common and influential formulations of the Precautionary Principle identified four such circumstances: (1) When we deal with important values that tend to be systematically downplayed by traditional decision methods – such as human health and the environment. (2) When we suspect that the decision might lead to irreversible and severe consequences and the values at stake are also irreplaceable, (3) When timing is at least as important as being right. (4) When it is more important to avoid false negatives than false positives. This interpretation of the Precautionary Principle does not say anything about what kind of actions to take when extra precaution is called for, but it does provide a clear and practically useful list of circumstances that call for extra precaution and that is not subject to the most common objections to the Precautionary Principle.

The precautionary principle has been widely discussed in the academic, legal, and policy arenas. This paper argues, however, that there is no single precautionary principle and we should stop referring to ?the? precautionary principle. Instead, we should talk about ?precaution? and ?precautionary approaches? more generally and identify and defend distinct precautionary principles of limited scope. Drawing on the vast literature on ?the? precautionary principle, this paper further argues that the challenges of decision making under conditions of uncertainty necessitate taking a (...) precautionary approach to decision making that will enable us to understand what particular precautionary principles require of us on a case-by-case basis.

From over 2000 years ago the ideal expressed in the Hippocratic Oath has encouraged doctors never knowingly to do harm: primum non nocere. Over 25 years ago the management writer Peter Drucker proposed it as the basis of a management ethic, ‘the right rule for the ethics managers need, the ethics of responsibility’.1 He argued then that the rule had wide scope encompassing for instance executive compensation, management rhetoric and the management of business impacts. In 2000 the United Nations Global (...) Compact embodied a Principle 7 enjoining ‘a precautionary approach to environmental challenges’ as defined in Principle 15 of the 1992 Rio Declaration. But what can such precautionary injunctions mean in practice? And what of conflicts with other values? Robin Attfield lays out the key questions he argues need to be asked about the Precautionary Principle if it is to be taken seriously and acted upon soundly. His focus is on the management of vulnerable resources — specifically planetary ecosystems — with whose management knowingly or otherwise we are all concerned. (shrink)

The application of the precautionary principle to an area of environmental protection, such as nature conservation, requires commitment to the idea that full scientific proof of a causal link between a potentially damaging operation and a long term environmental impact is not required. Adoption of the principle in Government statements related to sustainable development should therefore be seen in this context. The paper addresses the particular case of marine fish farming in Scotland where the principle was advocated but not upheld (...) in practice. In the light of this experience there is a need for educators and philosophers, ethicists and concerned scientists to ensure that the principle is more widely interpreted and understood. (shrink)

This open access book provides the first explicit case study for an application of the method of reflective equilibrium (RE), using it to develop and defend a precautionary principle. It thereby makes an important and original contribution to questions of philosophical method and methodology. The book shows step-by-step how RE is applied, and develops a methodological framework which will be useful for everyone who wishes to use reflective equilibrium. With respect to precautionary principles, the book demonstrates how a rights-based precautionary (...) principle can be constructed and defended. The case study succeeds in demonstrating that RE can be successfully applied and puts real constraints on the justification process. This is all the more remarkable as the case study was designed as an open-ended process, without presupposing any specific results. This book will be highly relevant both to people interested in philosophical methodology and epistemology, as well as to researchers who are interested in using philosophical methods and tools and applying them to practical problems.

It has been argued that geoengineering research should not be pursued because of a slippery slope from research to problematic deployment. These arguments have been thought weak or defective on the basis of interpretations that treat the arguments as relying on dubious premises. The paper urges a new interpretation of these arguments as precautionary arguments, i.e. as relying on a precautionary principle. This interpretation helps us better appreciate the potential normative force of the worries, their potential policy relevance, and the (...) kind of evidence required by slippery slope arguments. Understood as precautionary arguments, it is clear that slippery slope arguments against geoengineering capture concerns that are worth taking seriously. (shrink)

In June 1995, a campaign by Greenpeace forced the multinational oil company Shell to cancel its planned disposal of a redundant oil installation in the Atlantic. The Brent Spar incident attracted massive publicity and was influential in changing government policy on marine disposal of waste. During and following their campaign, Greenpeace were criticised as emotive and irrational by Shell and academic scientists. This paper looks at the arguments used during the debate, using literature, interviews and questionnaires. We investigate the use (...) of key environmental words and phrases and ask what is meant by rationality in this context. We discuss some of the lessons that should be learnt from the incident by policy makers and scientists. (shrink)

This article explores the question of how scientific uncertainty can be managed in medical decision making using the Advisory Committee on Immunization Practices as a case study. It concludes that where a high degree of technical consensus exists about the evidence and data, decision makers act according to a clear decision rule. If a high degree of technical consensus does not exist and uncertainty abounds, the decision will be based on a variety of criteria, including readily available resources, decision-process constraints, (...) and the available knowledge base, among other things. Decision makers employ a variety of heuristic devices and techniques, thereby employing a pragmatic approach to uncertainty in medical decision making. The article concludes with recommendations for managing scientific uncertainty in medical decision making. (shrink)

In 1998, Greenpeace, Natuur en Milieu(Nature and Environment), Milieudefensie(Environmental Defense), and the National ConsumersUnion presented a report about the possible risks andhazards associated with pesticide residues on fruitsand vegetables. Although these organizationsexplicitly denied having unassailable evidence on theharmful effects of pesticides, they claimed that bynow there are sufficient indications that pesticidesmay indeed lead to such health hazards. They used anappeal to the so-called precautionary principle tounderpin their claims. The committee officially incharge of deciding on the admission of pesticidesaccused the organizations (...) of scaremongering. Afterdistinguishing three possible versions of theprecautionary principle, we then show that the fourorganizations used in their campaign an improperversion of the precautionary principle to convince thegeneral public.

Risk governance of GM plants and GMfood products is presently subject to heatedscientific and public controversies. Scientistsand representatives of the biotechnologyindustry have dominated debates concerningsafety issues. The public is suspicious withregard to the motives of scientists, companies,and political institutions involved. Thedilemmas posed are nested, embracing valuequestions, scientific uncertainty, andcontextual issues. The obvious lack of data andinsufficient information concerning ecologicaleffects call for application of thePrecautionary Principle (PP). There are,however, divergent opinions among scientistsabout the relevance of putative hazards,definition of potential ``adverse effects,'' (...) andwhether actions should be taken to preventharm. The reliance on the concept ofsubstantial equivalence in safety evaluation ofGM food is equally controversial. Consequently,value assumptions embedded in a scientificframework may be a barrier for employment ofthe PP. One of our major conclusions is thatprecautionary GMP usage requires riskassessment criteria yet undeveloped, as well asbroader and more long-term conceptions of risk,uncertainty, and ignorance. Conflicts ofinterest and public participation are otherissues that need to be taken intoconsideration. GMP governance regimes that arejustifiable from a precautionary and ethicalpoint of view must transcend traditionalscientific boundaries to include alternativescientific perspectives as well as publicinvolvement.

This paper argues, mainly on the basis of Rawls''s savings principle, Wissenburg''s restraint principle, Passmore's chains of love, and De-Shalit's transgenerational communities, for a double interpretation of sustainable development as a principle of intergenerational justice and a future-oriented green ideal. This double interpretation (1) embraces the restraint principle and the argument that no individualcan claim an unconditional right to destroy environmental goods as a baseline that could justify directive strategies for government intervention in non-sustainable lifestyles, and (2) suggests that people's (...) concerns about the deterioration of nature and the environment articulate future-oriented narratives of self-identity that could fuel non-directive strategies to develop further responsibilities towards nearby future generations. Sustainable development, thus, provides sound arguments to restrict people's freedom to follow their own lifestyles, when these lifestyles transgress the baseline of the restraint principle. However, the individual freedom of choice should not be restricted for any further environmental considerations. Non-directive strategies are thus to stimulate the development of such further responsibilities towards nearby future generations. (shrink)

Ulrich Beck characterized the transition from modern to late modern society as a shift from an industrial to a “risk society.” Contemporary society is challenged by negative side effects of modernization, including the increasing and imminent threat of global climate change. This article will test the validity of conceivable prescriptive elements associated with this sociological theory. In doing so, it will focus on the most recent legal developments aimed at tackling climate change within the EU. This paper finds that the (...) precautionary approach is unable to sufficiently shape balanced legal intervention in this day and age. However, the approach adopted by the EU appears to be more successful in this respect. (shrink)

New techniques in genome editing have led to a controversial debate about the opportunities and uncertainties they present for agricultural food production and consumption. In July 2018, the Court of Justice of the European Union defined genome editing as a new process of mutagenesis, which implies that the resulting organisms count as genetically modified and are subject, in principle, to the obligations of EU Directive 2001/18/EG. This paper examines how key protagonists from academia, politics, and the economy strategically framed the (...) debate around genome editing in agriculture in Germany prior to its legal classification by the Court of Justice. It is based on an analysis of 96 official statements, including position papers, press releases, and information brochures. Our study reveals eight strategic frames used in the discourse on genome editing and uncovers the strategies used to disconnect from or connect with the previous discourse on green genetic engineering in the 1970s, 1980s and 1990s. Building on competitive framing theory, the study provides explanations for the use and emergence of counter-framing strategies and their success or failure in the debate around genome editing.

Nonuse values are a potentially very important, but controversial, aspect of the economic valuation of the environment. Since no use is envisaged by the individual, a degree of altruism appears to be the driving force behind nonuse values. Whilst much of the controversy has focused upon measurement issues associated with the contingent valuation method, this paper concentrates on the underlying motivations, whether ethical or economic, that form the basis for such values. Some fundamental aspects of defining and quantifying economic nonuse (...) values are considered, and possible motives for attributing value to the environment are analysed, making a clear distinction between 'selfish' altruism and 'selfless' altruism. The difference has crucial implications for economic valuation and for assessing individuals' willingness to pay for environmental quality. The concept of Safe Minimum Standards is introduced as a means of supplementing purely economic methodology to incorporate ethical concerns into decision making. (shrink)
