Climat et inégalités - 2026

The seminar provides a high-quality, expert-led discussion on the complex relationship between climate change and inequalities. Philippe Aghion’s presentation is particularly compelling, as he uses historical data to illustrate the correlation between economic growth and CO2 emissions, while also acknowledging the moral imperative to address climate change. His argument against degrowth is well-reasoned, pointing out that degrowth would disproportionately harm developing countries and that green innovation offers a more pragmatic path. The inclusion of Katheline Schubert, a leading environmental economist, adds depth to the discussion, likely covering the distributional impacts of climate policies and the importance of compensation mechanisms. Jean-François Delage’s perspective as a local mayor grounds the discussion in practical realities, highlighting the challenges of implementing climate policies at the municipal level. The seminar’s format, with Q&A sessions involving high school students, is commendable for fostering engagement and ensuring that the voices of younger generations are heard. However, the discussion could have been strengthened by more concrete data and case studies, as well as a deeper exploration of the political economy of climate policy. The absence of a fourth speaker, as mentioned, may have limited the breadth of perspectives. Overall, the seminar is intellectually rigorous and socially relevant, offering valuable insights for policymakers and the public alike.

The title accurately reflects the content, which focuses on the relationship between climate change and inequalities.

8/10

The seminar features renowned academics (Philippe Aghion, Nobel laureate in economics, and Katheline Schubert, professor at Paris School of Economics) and a local mayor, providing a high-level discussion grounded in economic research. The content is presented in an academic setting (Collège de France), ensuring a rigorous approach. However, the video is a recording of a seminar with limited visual aids and no formal citations, which slightly reduces its standalone reliability.
