Legal instruments and limits of ecological transformation

What legal options do cities have to be able to complete the transformation to a green, just, productive and healthy city in the sense of the New Leipzig-Charta 2021? What legal limits are they subject to in doing so? What answers do constitutions provide to the question of ecological transformation and the resulting social sustainability challenges?

Jacqueline Lorenzen conducts research on legal issues related to sustainable urban development. As cities are not only responsible for a significant share of greenhouse gas emissions in global terms, but at the same time exhibit a particular vulnerability to the consequences of climate change, they are important actors in the context of the necessary transformation processes. In spatial planning and among architects, various recent instruments and concepts (e.g. "vertical city", "sponge city", "resilient city") are discussed to cope with these processes, which Jacqueline Lorenzen examines in more detail from the perspective of administrative law and administrative science. In addition, she devotes herself to the dogmatic and theoretical penetration of climate protection and environmental energy law, which is characterized by numerous current and dynamic developments and novel individual issues. Finally, it illuminates constitutional sustainability issues, taking into account environmental science concepts such as that of the "Anthropocene" or the "planetary boundaries." Since the ecological transformation is increasingly developing into a social sustainability challenge, she also directs attention to the (constitutional) legal management of problems of equality of burdens and distributive justice.

Curriculum vitae

Jacqueline Lorenzen studied law at the University of Heidelberg (2010-2015). She subsequently completed her doctorate there with a thesis on the "Control of a differentiating EU self-government", which was published in 2019 and awarded the University of Heidelberg's Ruprecht-Karls-Preis in 2020. After her legal clerkship in the district of the Higher Regional Court of Munich (2018-2020), she worked first as an academic assistant, later as an academic councilor (a.Z.) at the Heidelberg Institute for German and European Administrative Law (Chair of Prof. Dr. Dr. h.c. Wolfgang Kahl, M.A.). In addition, she worked as a postdoc at the Interdisciplinary Research Network "Environments - Upheavals - Rethinking" at Heidelberg University from 2020 to 2022. Since April 2023, she holds the Argelander Professorship for the Law of Sustainability and Ecological Transformation.
