What Actierra does

Actierra is a French engineering consulting firm specialized in ecological transition, operating as a wholly-owned subsidiary of Ingérop, a diversified engineering group. The firm employs a community of nearly 300 experts across 17 agencies in France and structures its offerings around eight core expertise areas: Pilotage 360, Climate, Water, Sustainable Development, Sustainable Building, Biodiversity, Evaluation & Impact Measurement, and Regulatory Environment. Its client base consists of public and private project owners (maîtres d'ouvrage), served through direct advisory and operational studies spanning the full project lifecycle from upstream strategy to facility operation. Actierra emphasizes a 360-degree approach that places environment at the root of each project, claims financial and capital independence as a governance principle, and invests 10% of hours in R&D.

The firm has developed two proprietary technology tools that anchor its methodology positioning: InfraCOST, a suite for monitoring project carbon footprint from design through realization using life cycle analysis, with methodology certified by the Association pour la Transition Bas Carbone (ABC); and Écothemis, developed since 2021, which quantifies biodiversity losses and gains and sizes compensatory measures following the Office Français de la Biodiversité (OFB) 2021 guidelines. Three wholly-owned subsidiaries extend the service footprint: L'Atelier des Territoires (territorial development), Citizing (consulting services), and CityClimateX (climate services). Channels include the corporate website with a publications library, a multi-media mediathèque, and a LinkedIn presence.

The business model is professional services on a project-quotation basis, with pricing determined by scope, complexity, and engagement duration. GTM is enterprise field sales via direct engagement with project owners through the 17-agency French network. The company is privately held, registered in Nanterre (SIREN 833 378 789), with €1,000,000 of registered social capital, and no public revenue disclosure is available in the source data.
