Keynotes

Explore how knowledge, narratives, and power shape our understanding of sustainability around this years theme Facts, Fiction and Sustainable Futures of the YHYS Fall Colloquium 2026. Bringing together leading scholars from across disciplines, our keynote speakers, Catriona McKinnon (University of Exeter), Malcolm Fairbrother (Uppsala University), Tero Toivanen (University of Helsinki), and Johanna Kaakinen (University of Turku), offer critical perspectives on climate politics, environmental governance, societal transformation, and the psychology of belief. On this page, you’ll get a glimpse into their talks alongside brief biographies.


It is well documented that fossil fuel multinational corporations have engaged in a propaganda campaign of climate denial since at least the 1970s, with the aim of slowing down action on decarbonisation. In this talk I consider whether the CEOs of these carbon majors ought to be held liable under a version of international criminal law, because this propaganda has likely accelerated the climate crisis. I argue that international criminal law ought to be expanded to protect humanity against threats of extinction that are being imposed on us by some powerful subsets of our species. I call this new international crime ‘postericide’. I argue that individual CEOs are liable for this crime, and that the legal excuses they might offer in their defence fail.

Catriona McKinnon (exeter.ac.uk) is Professor of Political Theory at the University of Exeter. Her work engages ethical and philosophical questions related to climate change, the environment, and future generations in particular. She is the co-director of RENEW: Renewing Biodiversity Through a People-in-Nature Approach. A five year programme funded by Natural Environment Research Council (NERC) brings together academics from all Faculties at Exeter, and dozens of external partners, to research and implement solutions to the UK’s biodiversity crisis.


One of the most powerful arguments against climate policymaking is that fossil fuels generate energy that modern societies need, and without which the quality of human life would be much diminished. In other words, it serves the interests of those seeking to maintain the (high-carbon) status quo for the world to believe that a (low-carbon) future is impossible or at least impoverishing. I will argue in this talk that variation in national greenhouse gas emissions per capita, and the reasons for that variation, can serve as powerful proof against such delayist claims. And advocates of climate action — in relentlessly criticizing the performance of all countries rather than emphasizing the differences among them — are too often missing the opportunity to use this powerful proof.

Malcolm Fairbrother (fairbrother.org), professor of sociology at Uppsala University and the Institute for Futures Studies, researches climate and environmental policy and politics, social and political trust, globalization, and social science research methods. Originally from Vancouver, Canada, he received his PhD from the University of California, Berkeley; worked for ten years in the School of Geographical Sciences at the University of Bristol; and has been a visiting researcher at institutions in Mexico, the U.S., Canada, Italy, and Catalonia.


Despite widespread public concern over climate and ecological crises, the politics of sustainability are increasingly shaped not only by backlash but — perhaps more importantly — by the rearticulation of environmental ideologies. The far-right is becoming an active participant in this process. My talk examines the rise of far-right pro-environmental agendas, drawing on interview material with Finnish far-right actors engaged in environmental and metapolitical projects. Rather than rejecting environmental knowledge outright, the far right selectively appropriates, reinterprets and reframes it, producing hybrid political assemblages of facts and fictions that challenge progressive understandings of sustainability. I conceptualise this evolving formation as racial ecology: an ethnically exclusionary political ecology grounded in ideas of bordered belonging, local embeddedness and civilisational survival.

Tero Toivanen (helsinki.fi) is a historian and environmental social scientist specialising in the political economy of socio-ecological transformations and the environmental history of political and economic thought. He is a senior researcher at the BIOS Research Unit and in Economic and Social History at the University of Helsinki. He leads the project Climate Obstruction in Finland (2025–2028), funded by the Kone Foundation.


Attitudes toward science and scientific knowledge — for example, on climate change and biodiversity loss — seem to be polarized and politicized. However, according to national surveys like the Finnish Science Barometer, Finns’ attitudes toward science are generally quite positive, raising the question of why the public discussion around these topics seems so polarized. In the Fostering Finnish Science Capital (FINSCI) project, we have studied how Finns relate to science and scientific knowledge, including their beliefs about climate change. In this talk, I will present recent findings from the FINSCI project, and discuss the factors that shape people’s beliefs. I will also discuss what these findings might tell us about polarization around science-related topics more broadly.

Johanna Kaakinen (utu.fi) is Professor of Psychology at the University of Turku, Finland. Her research falls within the field of cognitive psychology, with a particular focus on the role of emotional experiences in information processing, especially in the context of reading. Kaakinen led the Strategic Research Council-funded project Fostering Finnish Science Capital (2020–2026), which examined the factors shaping people’s attitudes toward science and research, and related aspects.
