The Transition

Institute 1.5

The Transition Institute 1.5 (TTI.5), with its name echoing the IPCC’s target of limiting global temperature rise to 1.5°C, is an initiative launched by Mines Paris – PSL with the support of its Foundation. Dedicated to the design of the transition, the Institute aims to provide scientifically informed solutions to the major challenge of climate change, focusing on issues related to adaptation, mitigation, and biodiversity.
