Planning a project or preparing a permit application?
Speak with our experts to define the right assessment strategy and secure your regulatory pathway.
To remember
- Support permitting, compliance and project decisions
- Combine modelling, assessment and health-risk expertise
- Built for industrial, urban and sensitive projects
Your challenges
- Secure permits and regulatory approvals with studies that meet French and European expectations
- Demonstrate compliance with environmental and health requirements
- Handle complex, sensitive cases: dense urban areas, vulnerable populations, odor nuisances, radiological or accidental releases
- Deliver on time without compromising the robustness of the assessment.
Our solutions
We cover the full range of air-related regulatory assessments:
- Air Quality Impact Assessments: current conditions, project impact and compliance with regulated values
- Air & Health Assessments (Levels I to IV): for road infrastructure and urban development projects, following the Cerema guidance
- Health Risk Assessments (ERS) and Interpretation of Environmental Conditions (IEM): for industrial facilities, including measurement campaigns
- Odor Impact Assessments: for sites facing nuisance and local-acceptability issues
- Radiological Impact Assessments: normal operation and accident situations, with doses compared to regulatory limits.
- Wind Comfort Studies: pedestrian comfort around buildings and urban projects.
- Urban Heat Island Studies: assessing the thermal impact of urban projects.
We also support data center projects, assessing the air quality impact of backup generators through 3D dispersion modelling, including prolonged-outage scenarios.
Each study follows a structured chain, adapted to your project and its regulatory context:
Emissions assessment → Atmospheric dispersion → Exposure analysis → Health-risk evaluation
We add field measurements when the situation requires them, and we adapt the level of analysis to the stakes of your project. We do not do more than needed, and we do not do less than your regulator will expect.
Need field data? We also offer measurement campaigns alongside our studies. Discover our Air & Odor on-site diagnostics
