Key trends in 2025

The French landscape of transition consulting firms is changing rapidly. It is estimated that around 25,000 employees work in ecological and social transition consulting in France today. Nevertheless, the sector is still fairly concentrated, with 61% of consultancies based in the Paris region and 57% with more than 10 employees.

Faced with strong demand from companies, we can also observe that the largest consultancies are increasingly developing their sustainability practice. For many, the strategy adopted is to acquire smaller transition consultancies. Examples include Baker Tilly (which acquired Goodwill Management and Act21), Atos (which acquired EcoAct), BCG (with Quantis), Kea Partners (with Nuova Vista), and Bearing Point (with I Care).

These transition consultancies are also increasingly coming together in communities within the Mouvement Impact France (66 firms), Association Bilan Carbone (25), Social Value France (20) and CEC Consulting (17).
