What Naldeo Group does

Naldeo Group is an independent French engineering and consulting firm specializing in climate and environmental transition for industries and territories. The company provides technical, regulatory, and financial advisory services across the full project lifecycle — from feasibility studies, environmental permitting, and audit/due diligence to project management, worksite supervision, and operational optimization. It serves cities and local authorities (including 30 of the largest French cities and 200+ territorial authorities), industrial groups (100+ major industrial sites), and financial institutions, delivering approximately 1,500 projects per year through a network of 13 French offices headquartered in Lyon, with international work spanning up to 40 countries via partnerships with multilateral organizations.

The group's technical platform combines proprietary digital tools — ENERBIRD® (an energy management system deployed at roughly 60 solar and wind plants totaling 180+ MWp in French overseas territories), Enersquid® (an open multi-energy simulation platform originally developed for the SKA telescope project), Sunbiose (agrisolar modeling and control), Industrial Metrics, FieldO (field data collection), Terradata (data exploitation for climate optimization), and MSC (concession monitoring) — with deep domain consulting across five practice areas: energy transition and decarbonization, water transition, sustainable cities and regions, waste management, and environment/biodiversity. Specialized capabilities include BIM methodology, drone-based LiDAR and thermal surveying, 360° virtual site tours, and an AI-based subscriber classification algorithm for water utilities. The group also co-leads the 16-partner Ch0C consortium developing a low-carbon oxycombustion industrial boiler.

Naldeo operates a project-based, fee-for-service business model, typically winning mandates through competitive tenders (appels d'offres) and long-term client relationships, with selective acceptance limited to projects aligned with the EU green taxonomy. The group is privately held as a SAS with EUR 2,353,250 in share capital and operates wholly-owned subsidiaries including Naldeo Stratégies Publiques, Naldeo Technologies et Industries, and Naldeo Digital for Climate, alongside an in-house research institute, the Institut de la Transformation Climat (ITC). The group is quadruple ISO-certified (9001/14001/45001/50001), holds 30+ Opqibi and Qualimetha qualifications plus MASE certification, and reports that its 2023 missions avoided 86,000 tonnes of CO2 equivalent emissions.

Broad incumbents

• Egis: Major French-headquartered engineering and consulting group with deep presence in energy, water, environment, and urban infrastructure. Directly competes with Naldeo for French public-sector AMO mandates and shares the same selective client base across cities and territorial authorities.
• Tractebel (Engie): Global engineering consultancy within Engie group covering energy, water, and urban infrastructure. Competes with Naldeo on large industrial decarbonization, renewable energy feasibility, and concession advisory mandates; significantly larger and better capitalized.
• Suez Consulting: Consulting arm of Suez group with strong water, waste, and circular-economy expertise. Closely comparable to Naldeo's water and waste management practices, competing for municipal and industrial environmental advisory mandates across France and internationally.
• Bureau Veritas: Global testing, inspection, and certification leader with a growing sustainability and ESG assurance line. Competes with Naldeo in industrial site certification, environmental compliance audits, and increasingly in ESG due diligence for financial institutions.
• WSP France: Global professional services firm with a substantial French practice covering environment, water, energy, and sustainable cities. Competes with Naldeo on large public-sector environmental consulting mandates and on industrial decarbonization programs.
