Climate Change and Climate Crisis

This lecture series is a sequel to the lecture series "Climate change and climate crisis. Interdisciplinary perspectives", "Climate change and climate crisis. Future perspectives and concepts", and Climate change and climate crisis. Transformative concepts and innovation".

It will address current issues of climate change and climate crisis through the lenses of various disciplines, such as climate science, geography, economics, cultural studies, political science, law, finance and more.

All of the national and international speakers are well-known researchers in their respective fields and beyond. Many of them participate in public debates about the probable effects of the current climate crisis and about possible remedies.


Join us for the panel discussion on "Climate Crisis and Intergenerational Justice"


What will our future look like if we don't act now?

The issue of intergenerational justice revolves around this question, which, at the latest since the emergence of Fridays for Future, has also led children and young people around the world to demand effective action.

From a legal point of view, this term plays an increasingly important role in the fight against climate change in the context of so-called "climate lawsuits". What is being demanded here is a fair distribution of burdens between the generations. Nevertheless, the term "intergenerational justice" and its connection to children's rights is still little illuminated in Austria. Therefore, it will be discussed what is meant by intergenerational justice – especially from a children's rights perspective – where this argument has already been applied in legal proceedings and how this argumentation could perhaps also be made usable in Austria. 

Moderation: Elisabeth Nemeth (UNIVIE)

Discussants: Sebastian Öhner (KJA Wien), Angela Kallhoff (UNIVIE), Nikolaus Handig (BOKU)

Sebastian Öhner, legal officer at the Vienna Children's and Youth Ombudsman's Office (KJA Wien) and board member of the Austrian League for Human Rights, studied law in Vienna and Istanbul University (TR).

Angela Kallhoff, professor at the Department of Philosophy (UNIVIE), focuses on ethics, political philosophy and applied ethics in her research.
