ABSTRACTThis article offers a constructive critique of the Oxford Principles for the governance of geoengineering and proposes an alternative set of principles, the Tollgate Principles, based on that critique. Our main concern is that, despite their many merits, the Oxford Principles remain largely instrumental and dominated by procedural considerations; therefore, they fail to lay the groundwork sufficiently for the more substantive ethical debate that is needed. The article aims to address this gap by making explicit many of the important ethical (...) questions lurking in the background, especially around values such as justice, respect and legitimacy.

The Carnegie Council's work “is rooted in the premise that the incorporation of ethical concerns into discussions of international affairs will yield more effective policies both in the United States and abroad.” In honor of the Council's centenary, we have been asked to present our views on the ethical and policy issues posed by climate change, focusing on what people need to know that they probably do not already know, and what should be done. In that spirit, this essay argues (...) that climate change poses a profound ethical challenge, that the ongoing evasion of this challenge produces ineffective policy, and, therefore, that a fundamental paradigm shift is needed. More specifically, I maintain that the climate problem is usually misdiagnosed as a traditional tragedy of the commons, that this obscures two deeper and distinctively ethical challenges, and that we should address these challenges head on, by calling for a global constitutional convention focused on future generations.

Some authors have called for increased research on various forms of geoengineering as a means to address global climate change. This paper focuses on the question of whether a particular form of geoengineering, namely deploying sulfate aerosols in the stratosphere to counteract some of the effects of increased greenhouse gas concentrations, would be a just response to climate change. In particular, we examine problems sulfate aerosol geoengineering (SAG) faces in meeting the requirements of distributive, intergenerational, and procedural justice. We argue (...) that SAG faces obstacles to meeting the requirements of all three considered kinds of justice, because its impacts can harm some persons and communities much more than others; it poses serious risks to future generations; and SAG is especially prone to unilateral implementation. While we do not claim that SAG ought not to be implemented, we argue that it is the responsibility of proponents of SAG to recognize and address these ethical obstacles before advocating its implementation.

“[T]he Precautionary Principle still has neither a commonly accepted definition nor a set of criteria to guide its implementation. “There is”, Freestone … cogently observes, “a certain paradox in the widespread and rapid adoption of the Precautionary Principle”: While it is applauded as a “good thing”, no one is quite sure about what it really means or how it might be..

We are living in a climate of risk. Our way of life imposes risks on ourselves and others. We are causing climatic changes that have the potential to change radically the conditions under which both we - the presentgeneration - and future generations will live. While we are now quite certain that climate change is happening, we are unsure of exactly what will happen and when, given different emissions and policy scenarios. We are therefore in a position where we must (...) decide what to do about the risks climate change threatens in the face of a range of uncertainties In this book, Lauren Hartzell-Nichols provides guidance in the face of this uncertainty by offering an in-depth discussion of how and why we ought to take a precautionary approach to climate policy, namely by appeal to a Catastrophic Precautionary Principle and Catastrophic Precautionary Decision-Making Framework. By examining the way in which climate change is harmful, Hartzell-Nichols shows how precaution does have a meaningful role to play in moving climate policy forward if we reconsider what precaution is about before too quickly appealing to precaution as a reason or justification for action. A Climate of Risk takes a philosophically grounded, interdisciplinary approach that will appeal to a broad scholarly and policy-oriented audience. Hartzell-Nichols's reinterpretation of the precautionary principle enables precaution to be more effectively leveraged as a driver of action on climate change. (shrink)
