The Zeronauts is both a book and a campaign.

Written by Volans co-founder John Elkington, the book lays out an agenda for the sort of transformative, system change needed to break what John has dubbed the 'Sustainability Barrier'.

The campaign will work to spotlight the growing need to push towards – and in some cases beyond – zero in carbon, waste, toxics, population growth, poverty and pandemics.

Founded in 2008, Volans aims to help drive the next great economic transformation.
