Jean-Marc Jancovici deciphers the physical constraints shaping our economic future. Energy, climate, sovereignty, industry and artificial intelligence: he helps leaders and organisations understand risks and build robust strategies in a constrained world.
Jean-Marc Jancovici explains the links between energy, economics and climate to help decision-makers understand the transformations reshaping our future.
A graduate of École Polytechnique and Télécom Paris, he has become one of the most influential voices on energy and climate. His approach starts from a simple principle: behind the economy there are always physical flows, energy and resources.
In the early 2000s, he developed the Bilan Carbone® methodology with ADEME, which became a reference for measuring greenhouse-gas emissions. In 2007, he co-founded Carbone 4, a consulting firm specialising in decarbonisation and climate adaptation.
Jean-Marc Jancovici is President of The Shift Project, a think tank dedicated to transforming the economy in response to energy and climate constraints. In 2026, his work puts a new concept at the centre of the debate: robustness. How can organisations keep functioning when energy, climate, raw materials and supply chains become unstable?
A lecturer at Mines Paris, author and speaker, he makes complex subjects accessible through figures, orders of magnitude and a direct style. His graphic novel World Without End, created with Christophe Blain, became a major publishing success and helped bring energy and climate issues to a broad audience.
Understand physical constraints to make better decisions.
Jean-Marc Jancovici places major economic and technological issues back in the physical world: energy, raw materials, infrastructure and climate.
Decarbonise to preserve the ability to act.
Energy, climate, geopolitics and raw materials: how can a company prepare for a world in which crises are becoming more frequent and increasingly interconnected?
Energy dependence has become a strategic risk.
Oil, gas, electricity and raw materials: Jean-Marc Jancovici explains why decarbonisation now goes far beyond climate alone. It directly affects sovereignty, competitiveness and our ability to make decisions.
Artificial intelligence is not immaterial.
Data centers, semiconductors, networks, and electricity: AI relies on a considerable physical infrastructure. Jean-Marc Jancovici asks a crucial question: which digital uses should we prioritize in a world where energy remains limited?
Decarbonisation is no longer enough. We must also adapt.
Heatwaves, drought, water, agriculture, infrastructure and real estate: climate change is already transforming the conditions in which organisations operate. How can companies prepare today for tomorrow's climate?
Our civilisation is a gigantic energy machine.
Drawing on the key lessons of World Without End, Jean-Marc Jancovici explains how energy has shaped our societies and why dependence on fossil fuels is now changing the rules of the game.
Jean-Marc Jancovici speaks at the key moments where people, performance and impact matter.
