Raison d'être
Our mission

"Accelerate the transition to a decarbonized society by setting the actors of society in motion"

For this, we create, thanks to the 2tonnes workshop, immersive, allegorical and educational experiences for individuals in order to:

  • Empower them (and not make them feel guilty) and make them aware of their power to act

  • Make them want to act for an objective to which they adhere for its ambition and its values

  • Make them want to act because they thrive in action


Project governance

Governance is structured around 2 organisations:

  • Social and Solidarity Economy Company, SAS 2tonnes Company, created and directed by François Laugier and Pierre-Alix LLORET, which develops the 2tonnes workshop and manages its distribution in a professional setting (which we call between us "La Forge")

  • Association law 1901, the Association 2 tons, whose mission is to allow the use, by the greatest number, of the tool in a voluntary framework (which we call between us "The Village"). The association organizes workshops for the general public led by volunteers, and brings together the community of facilitators through events, campaigns, seminars, etc. All facilitators can be members of the association, and elect a Board of Directors at the General Assembly. Administration composed of 7 members by majority judgment vote.


Impact project, driven by the general interest and reaching very different audiences, 2tonnes has chosen to become more professional in order to increase its impact and accelerate the dissemination of the workshop.   To do this, we had to invent the governance model that was best suited to fulfilling our purpose.

Francois LAUGIER


Idol: Louis de Funès

After graduating as an engineer from Centrale Lyon in 2018, he took a deep interest in environmental issues and got involved in several associations such as Climate Fresk (animator and trainer), Réseau Mycélium (co-founder) and PikPik Environnement.

These experiences have reinforced his interest in the psychology of change and pedagogy, and to make it his profession. Independent consultant and trainer, he has supported several companies in carrying out their Carbon Assessment, and built tailor-made training. He also created the workshop "How to act for the climate" in 2019, and carried the project until he joined forces with Pierre-Alix.

He admires Louis de Funès for his talent, his originality, his humour, but also his humility and his quest for excellence.

Animal totem: The warthog

Former Director of Operations in team mobilization consulting in Canada, he then left for Argentina, where he co-founded an energy transition consulting company, before returning to France and meeting François via Climate Fresk.

Passionate about the organizational and cultural aspects of change, Pierre-Alix is responsible for the development of 2tonnes in companies, partnerships, communication and the structuring of the community of facilitators.

Why the warthog? For this mix of power, self-mockery and subtlety. And also because he never tires of the sound of the word "warthog"

Passionate about topics related to ecology and sustainable development, Jimmy discovered 2tonnes during the 7th season of Data For Good, which launched the platform.

Formerly Data Engineer and now Data Analyst at Phenix, Jimmy helps 2tonnes in his free time, especially on the development of the back-end part of the platform and the management of its database. It also contributes to the reflections on the definition of the new functionalities of the platform.


What is #ShowYourStripes? He lets you go look on the internet. Why ? Because it's simple, understandable, revealing, and he feels it's important to remember why we're all doing this.

Animal totem: The stick insect

An engineer by training, Augustin has been working as a Data Scientist since leaving school in 2018.

He discovered 2tons by participating in one of the first public workshops, then got involved in the project during the call for contributions for DataForGood in February 2020.

His contribution mainly concerns the implementation of the simulator: from the calculation of the carbon footprint to the effects of actions.


Why the stick insect? He doesn't like to be the center of attention and prefers to blend into the background. Move along, there's nothing to see !

Model, sources and data

The 2ton workshop is an educational experience which is based on a data model to simulate, in a quantified way, low-carbon transition scenarios.

Data is therefore an educational tool, and we are very demanding with regard to model accuracy, and the sources used. They make it possible to give the experience its consistency and his credibility.

The calculation methodology during a 2ton simulation is based on 3 models which interact with each other:

  • The carbon footprint model calculates the carbon footprints of the participants and the population, using data from Ademe, the OECD, the FAO...

  • The stock model updates the characteristic data of the participants and the population, based on assumptions from reference works on the subject (RTE, négaWatt, Ademe, etc.)

  • The influencing model quantifies the societal dynamics taken into account in the simulation, drawing inspiration from the notions of behavioral sciences
