The book Twomorrow looks back on a European tour of solutions to climate change. Released in 2022 and self-published by a couple, Twomorrow sets off to explore 26 countries in a van to interview those who are shaping a more sustainable world. The book is 256 pages, and is printed in Brest from FESC, PSC paper, with vegetable inks. Inside, three main categories: the "issues", to fully understand the problems of the most emitting sectors (transport, food, energy, etc.), the "interviews" of 17 companies offering concrete solutions, already established on the market, with resources to go further, and finally the "travel diaries" pages, to discover the European itinerary by van and inspire people to travel nearby. The cover is made by Malika Favre, a French artist known for her covers of Vogue, New York Times, etc. The feedback from the first 2000 readers on the book: "It's super pleasant to read and interesting, between the moments of travel, the little factual reminders on lots of subjects and the discovery of lots of super interesting companies"; "The book is very well done, didactic by always relying on the context, the basics of the issues and seeing all these innovative solutions is good! The way of articulating the content is finely thought out and very intelligent!".
