L’équipe NUMTECH, ingénierie environnementale

Who are we?

Understanding and reducing environmental impacts

Founded in 2000 from the meeting of atmospheric sciences and mathematical sciences, NUMTECH first deployed its expertise in modelling and understanding atmospheric phenomena: air quality, meteorology and health impact.

Driven by the environmental commitment of its teams, the company gradually expanded its fields of activity towards mitigating the environmental impacts of human activities. Today, risk analysis and environmental performance are fully at the heart of our work.

This expertise has been developed through internal R&D projects and with academic and public partners (University, CNRS, INRIA, Météo-France, INERIS, CEA…). Each year, NUMTECH devotes between 10 and 20% of its turnover to innovation.

Our mission: To help you understand and reduce the environmental impacts of your activities in order to collectively commit to preserving the environment and public health.

NUMTECH, a brand of the foril Groupe

In 2022, NUMTECH joined the fortil Group to become its environmental brand. fortil is an engineering and technology consulting group, with more than 2,000 employees in France and abroad. The fortil model, designed by engineers with an entrepreneurial spirit and guided by values close to ours, strengthens our environmental expertise on a solid technological foundation.

Based in Clermont-Ferrand since its creation, in the Puy-de-Dôme region, NUMTECH is deeply attached to its territory. In March 2025, the company moved into the Centre des Matériaux Durables (CMD), located in the Parc Cataroux, an initiative led by Michelin.
