Sustainability science seeks to extend scientific investigation into domains characterized by a distinct problem-solving agenda, physical and social complexity, and complex moral and ethical landscapes. In this endeavor, it arguably pushes scientific investigation beyond its usual comfort zones, raising fundamental issues about how best to structure such investigation. Philosophers of science have long scrutinized the structure of science and scientific practices, and the conditions under which they operate effectively. We propose a critical engagement between sustainability scientists and philosophers of science with respect to how to engage in scientific activity in these complex domains. We identify specific issues philosophers of science raise concerning current sustainability science and the contributions philosophers can make to resolving them. In conclusion, we reflect on the steps philosophers of science could take to advance sustainability science.

Sustainability transformations call forth new forms and systems of knowledge across society. However, few tools and processes exist for promoting dialogue among different interests and normative stances in knowledge co-creation. In this article, we build on the notion of thought collectives to argue that understanding and moderating normative tensions are necessary if sustainability science is to provide successful solutions. Drawing on an analysis of the normative tensions between rival high-tech and low-tech thought collectives in the mobility and food production sectors, we discuss three strategic approaches: applying common evaluative frameworks, building contextual convergence and embracing complexity. We argue that these strategies indicate a need to distinguish different kinds of reflexivity in managing tensions among thought collectives. As a practical conclusion, we establish sets of reflexive questions to help sustainability scientists deploy the knowledge management strategies discussed.

This paper investigates practice, frameworks and philosophy in the field of ecological management, a novel integrative approach to closing the gap between ecological and economic theoretical models and ecological and economic behavior. First, I will present the current status in this emerging field and discuss management in relation to various sub-disciplines, including agroecology, circular economy, industrial ecology, and urban sustainability. This provides a basis to analyze the theoretical frameworks found in profitable, ecologically-based businesses and identify key general features that characterize this approach, notably the relationships between: an enterprise's diversity and its economic resiliency; zero waste policies and societal and environmental impacts; and affordances of the local environment and business' long-term economic viability. Finally, the philosophical issues looming behind are discussed, notably problems regarding interdisciplinarity and the relation of ethical frameworks with management. Through use of the model-centered philosophy of science to disentangle some of these conceptual problems, I argue that ecological management has a unique place in sustainable development as an independent exploratory tool for constructing and testing economic and ethical models in the Anthropocene.

The recent proliferation of types and accounts of experimentation in sustainability science still lacks philosophical reflection. The present paper introduces this burgeoning topic to the philosophy of science by identifying key notions and dynamics in sustainability experimentation, by discussing taxonomies of sustainability experimentation and by focusing on barriers to the transfer of evidence. It integrates three topics: the philosophy of experimentation; the sustainability science literature on experimentation; and discussions on values in science coming from the general philosophy of science, the social sciences, and sustainability science. The aim is to improve understanding of how sustainability experimentation has evolved, from a broader picture of the history and philosophy of science, with a specific focus on understanding evidence production and how evidence traveling in and from sustainability experiments can be improved, particularly in the context of complex and pervasive normative commitments of the research. By engaging in these topics, this research is one of the first philosophical accounts of sustainability experimentation, contributing both to the knowledge on specific philosophies of science and to the further development of an evidence-based sustainability science through a better understanding of the barriers to more relevant and usable knowledge.
