The journal Environmental Values is thirty years old. In this retrospective, as the retiring Editor-in-Chief, I provide a set of personal reflections on the changing landscape of scholarship in the field. This historical overview traces developments from the journal's origins in debates between philosophers, sociologists, and economists in the UK to the conflicts over policy on climate change, biodiversity/non-humans and sustainability. Along the way various negative influences are mentioned, relating to how the values of Nature are considered in policy, including (...) mainstream environmental economics, naïve environmental pragmatism, the strategic role of corporations, neoliberalism and eco-modernism/techno-optimism. At the same time core value debates around intrinsic value in Nature and instrumentalism remain relevant, along with how plural environmental values can be articulated and acted upon. Naturalness, human relations to non-humans, and Nature as other, remain central considerations. The broadening of issues covered by the journal (e.g. covering social psychology, sociology and political science), reflect the need to address both human behaviour and the structure of social and economic systems to confront ongoing social-ecological crises.

Ecological economics is an interdisciplinary science that is primarily concerned with developing interventions to achieve sustainable ecological and economic systems. While ecological economists have, over the last few decades, made various empirical, theoretical, and conceptual advancements, there is one concept in particular that remains subject to confusion: critical natural capital. While critical natural capital denotes parts of the environment that are essential for the continued existence of our species, the meaning of terms commonly associated with this concept, such as ‘non-substitutable’ (...) and ‘impossible to substitute,’ require a clearer formulation then they tend to receive. With the help of equations and graphs, this article develops new definite account of critical natural capital that makes explicit what it means for objective environmental conditions to be essential for continued existence. The second main part of this article turns to the question of formally modeling the priority of conserving critical natural capital. While some ecological economists have maintained that, beyond a certain threshold, critical natural capital possesses absolute infinite value, absolute infinite utility models encounter significant problems. This article shows that a relative infinite utility model provides a better way to model the priority of conserving critical natural capital. (shrink)

This article introduces an intuitive conservation dilemma called the Canyon Dilemma: Is it possible to condemn the mining of the Grand Canyon, even by a poor generation, while also permitting this generation’s mining of an unremarkable small canyon? It then argues that not one of several prominent theories of environmental justice, including various forms of egalitarianism, welfarism, deep-ecological theories, communitarianism and free-market environmentalism, can navigate this dilemma. The article concludes by highlighting the dilemma-navigating potential of the equal-claims idea – the (...) idea that the natural world is something to which every human being, present and future, has an equal, substantive claim.

No net loss approaches to environmental policy claim that policy should maintain aggregate levels of natural capital. Substitutability between natural assets allows losses in some assets to be compensated for by gains in others while maintaining overall levels of natural capital. This paper argues that significant goods that matter to people’s well-being will be lost through a policy of no net loss. The concepts of natural capital and ecosystem services that underpin the no net loss approach to environmental policy cannot (...) capture important dimensions of value that are central to human well-being.
