Abstract

This article starts from the long-term objective of the Paris Agreement on climate change to hold the increase in the global average temperature to well below 2 C above pre-industrial levels, and the global emission pathways compatible with this objective. It shows how translating these global emission pathways into national mitigation targets raises equity issues. It then analyzes the trajectory towards net zero emissions in 2050 set out in the French National Low Carbon Strategy. Finally, recent trends are compared to the trajectory-objective, and highlight, in hollow, the levers to reduce emissions and the transformations required.
