Facts, Fictions and Sustainable Futures

Despite the urgency of contemporary environmental crises, environmental action continues to encounter persistent and, in some contexts, intensifying resistance. Recent years have seen a growing wave of policy reversal and backlash, including growing opposition to the European Green Deal and (other) climate initiatives and the dismantling of environmental policies and institutions in the United States and elsewhere (e.g. Patterson 2023; van der Sluis 2023; Fiorino 2025). Yet, these dynamics do not unfold in the context of total erosion of trust or concern. In many societies, public awareness of environmental problems remains high and trust in institutions persists, albeit unevenly (Fairbrother et al., 2019; Franzen & Bahr, 2024). This blend of environmental concern and contestation of action points to the need for closer examination of how environmental knowledge is produced, circulated, mobilised and challenged in contemporary societies.

The YHYS Fall Colloquium 2026 brings together perspectives from environmental social sciences to examine the roles of facts and fictions in shaping sustainable futures. We understand facts not as neutral or uncontested, but as embedded in social, political and epistemic processes (e.g. Hajer 1995, Jasanoff & Kim 2019), and fictions not only as falsehoods, but also as narratives, imaginaries and strategic constructions that influence how environmental problems and solutions are understood (e.g. Celermajer et al. 2024; Lyytimäki 2023; Sokolova 2023). The interplay between facts and fictions is central to processes such as climate obstruction, environmental policy backsliding and the proliferation of climate denial and disinformation, as well as to the strategic use of environmental arguments as scapegoats or political resources (Toivanen & Lähde 2024; Krange et al. 2021; Lamb et al. 2020; Korppoo, Tynkkynen & Hønneland 2015).

Attention should also be directed to the power relations that shape whose knowledge counts, which voices are heard, and how expertise, uncertainty and ignorance are mobilized in environmental decision-making. These dynamics raise critical questions about the role of environmental knowledge in political contexts marked by competing priorities, entrenched interests and uneven capacities for action. They also invite reflection on how knowledge can be translated into compelling narratives capable of mobilizing action and countering resistance (Oreskes & Convey 2010; Arnal, Hilson & McKinnon 2019), as fictions are not only obstacles to environmental action but can also play a generative role (Milkoreit 2017). Narratives, imaginaries and speculative visions can help make future possibilities tangible, cultivate hope fostering collective engagement, and challenge dominant framings that sustain the status quo (McKinnon 2014). The entanglement of facts and fictions thus shapes not only how environmental crises are understood, but also how possible futures are envisioned and pursued.

YHYS Fall Colloquium 2026 invites contributions that explore these dynamics and their implications for sustainability governance and action. How can environmental social sciences illuminate and intervene in these processes in order to support pathways towards more sustainable futures?
