No collapswashing

Retranscription de la conférence d'Olivier Hamant organisée par le CAL Namur […] Olivier Hamant nous invite à questionner notre quête permanente de contrôle et de performance. A l'heure des bouleversements écologiques, il propose un regard original : et si nous nous inspirons du vivant ? Lent, imparfait et vulnérable, il nous montre qu'une autre manière d'organiser nos sociétés est possible, plus robuste et plus humaine.

Human activities are threatening to push the Earth system beyond its planetary boundaries, risking catastrophic and irreversible global environmental change. Action is urgently needed, yet well-intentioned policies designed to reduce pressure on a single boundary can lead, through economic linkages, to aggravation of other pressures. In particular, the potential policy spillovers from an increase in the global carbon price onto other critical Earth system processes has received little attention to date. To this end, we explore the global environmental effects of pricing carbon, beyond its effect on carbon emissions. We find that the case for carbon pricing globally becomes even stronger in a multi-boundary world, since it can ameliorate many other planetary pressures. It does however exacerbate certain planetary pressures, largely by stimulating additional biofuel production. When carbon pricing is allied with a biofuel policy, however, it can alleviate all planetary pressures. In the light of nine Earth Syst
