Launch of the Triple Accounting Chair

Paris/Marseille, September 9, 2025 — Goodwill Management, a sustainability consulting firm, and Aix-Marseille School of Economics — AMSE (Aix-Marseille University/CNRS), with the support of the Louis Bachelier Institute (ILB), launch the Triple Accounting Chair to 3 years. Led by Alan Fustec, founder of Goodwill-Management, this research chair reinforces the scientific foundations of the method of triple accounting Thesaurus-3K (T3K), a management tool that allows managers to integrate social and environmental dimensions with respect for planetary boundaries.

Why triple accounting?

Classic financial accounting ignores decisive assets — water, climate, biodiversity, internal skills, social cohesion. Their deterioration weakens the sustainability of businesses, but does not appear in the balance sheets.
La triple accounting fills this gap by monetizing these impacts and by adding, to the traditional result and balance sheet, two shutters complements:

• Social/societal value created or destroyed (precariousness, inclusion, work accidents, etc.)
• Environmental debt (GHGs, resource consumption, artificialization of soils, etc.)

The method T3K (Goodwill-management) integrates the logic of quotas Taken from planetary boundaries and calculate, in parallel with the financial result, a Excess or debt environmental and social.

Alan Fustec, director of the Chair: “A company can post €1 million in financial benefits while generating €2 million in environmental debt. In this case, she wrecked of value. Triple accounting acts as a electroshock and a lever for transformation.”

A scientific project for operational tools

The chair aims to Support and To make reliable T3K, with three priority areas:

1. Evaluate better the impact of an activity on biodiversity And the resources ;
2. Explore the links between thermodynamics and economics to rethink the concept of worthiness ;
3. Produce academic publications And a reference book.

Raouf Boucekkine, professor of economics (AMU), scientific director of the chair: “Give back the science at the heart of economic practices is the condition for managing the activity sustainably within the planetary boundaries.”

A 3-year roadmap

• Year 1 : scientific consolidation of the method and critical review existing models;
• Year 2 : experiments With voluntary businesses ;
• Year 3 : deepening fundamental On the concept of worthiness.

A simple, legible... and demanding framework

Beyond the profusion of indicators ESG, triple accounting offers a Binary language : is the company creator or Destructive valuable once The costs social and environmental integrated? This readability feeds the strategic decision, the governance and, ultimately, the concrete application of polluter pays principle.
