The Greening of Economic Law Education: A Source of Debate. The very principle of transforming legal education in the name of sustainability is open to debate. This raises questions about the scope and limits of academic freedom. Discussions are underway regarding the place of sustainability-related courses within the curriculum. In recent decades, the trend has been to incorporate courses on sustainability issues into optional and specialized courses offered at the Master’s level, for example through first- or second-year Master’s courses on environmental law, or even specialized Master’s programs in this field. This traditional structure responded to a dual trend. On the one hand, contrary to the conception that gave rise to it, economic law has increasingly been equated with business law, structured around objectives of economic and financial performance and the promotion of the economic rights and freedoms of businesses (protection of property, freedom of enterprise, etc.). On the other hand, environmental law specialists emphasized, in this context, the importance of conceiving environmental law as a branch of law with strictly ecological objectives. The worsening of the ecological crisis, however, has called into question this structure of academic pathways and the corresponding body of knowledge. On the one hand, it is becoming increasingly difficult to treat ecological issues as falling outside the scope of basic legal education, particularly in economic law. Indeed, environmental degradation is rooted in economic activities and their legal organization. The transformation of economic law—and its teaching—therefore appears to be a prerequisite for the ecological transition. On the other hand, current developments in environmental regulation demonstrate how susceptible it is to the interests of certain economic actors, and how its level of ecological ambition depends on the ability to first foster the emergence of more sustainable business models. The traditional divide between economic law and environmental law thus appears to be in crisis. Nevertheless, not all educators agree on the meaning of integrating sustainability issues into economic law curricula. For some, it is a necessary step to reflect the changes in positive law that have occurred in recent years. For others, it is an opportunity to introduce a more theoretical, critical, interdisciplinary, and forward-looking shift in legal education.
