Only in French | When a society, composed of individuals, is confronted with different options, finding a collective preference is necessary. But to move from particular interests to the general interest, the method matters and can change the result! That's the subject of the last Sciences Echos video by Charles Figuières (AMU/FEG/AMSE).

Quand une société, composée d'individus, est confrontée à des options différentes, il faut réussir à trouver une préférence collective. Mais pour passer des intérêts particuliers à l'intérêt général, la méthode importe et peut même changer le résultat !

Présentation : Charles Figuières

Les conférences Sciences Echos sont organisées en partenariat avec le rectorat de l'Académie Aix-Marseille et la bibliothèque de l'Alcazar.

The True Price of CO₂
In 2024, a grim record was set: it was the hottest year ever recorded on Earth. The signs of climate upheaval are now visible to all, as global warming manifests itself in a rapid rise in extreme weather events. In theory, the solution is straightforward: we must stop burning fossil fuels. In practice, phasing out energy sources so firmly entrenched in contemporary societies is an immense challenge. To reduce CO₂ emissions, economists — trained in cost–benefit analysis — can help policymakers design strategies that are both effective and socially acceptable.
