Supported by an association whose president is Jean Jouzel, the Grand Défi is an unprecedented, large-scale citizen initiative dedicated to the ecological transition of companies.

An initiative of The Great Challenge of Companies for the Planet

Overview of the project

The Grand Défi is an unprecedented participatory initiative, with a national ambition, which will take place in 2022 and which aims to accelerate the ecological transition of companies by formulating, disseminating and implementing a hundred or so concrete, impactful, measurable and verifiable action proposals.

To achieve this objective, the Grand Défi proposes to associate the business world, economic players, organised civil society AND the local actors in a three-stage process:

  1. The Grand Consultation (from February 2022) will make it possible to collect the concerns, needs and proposals of the company’s stakeholders (economic, territorial and societal actors) but also to bring out their common interests.
  2. The Grand Deliberation (from May 2022) will bring together representatives of 150 companies chosen at random according to four criteria (size, sector of activity, geographical location, status). During the work of the Great Challenge, these representatives will be divided into three bodies (60 employees, 60 managers and 30 investors). They will meet six times in Paris and in the regions to discuss with experts and work as a collective to formulate a set of concrete proposals. At the end of the deliberations, they will submit the proposals to the stakeholders to reinforce the legitimacy of their proposals.
  3. The Grand Dissemination (from autumn 2022) will finally allow the implementation of the proposals adopted by the 150 deliberators AND validated by the Grand Challenge partners to be carried, disseminated and supported. An open source and collaborative website dedicated to the transition of companies will also be launched.
