To remember
  • Support permitting, compliance and project decisions
  • Combine modelling, assessment and health-risk expertise
  • Built for industrial, urban and sensitive projects

Your challenges

  • Demonstrate compliance clearly with regulated limit values and environmental requirements.
  • Manage complex assessments involving emissions, dispersion, exposure and health-risk evaluation.
  • Assess impacts credibly for industrial sites, urban developments and infrastructure projects.
  • Work under pressure from deadlines, regulatory expectations and multiple stakeholders.
  • Address specific cases such as odor, radiological impacts or accidental releases. 

Our solutions

We deliver regulatory studies that turn complex technical analysis into clear, defensible results.
    • Air quality impact studies to assess current conditions and compliance with regulated values. 
    • Air & health impact studies for urban development projects and industrial facilities. 
    • Odor impact studies for sites facing nuisance and local-acceptability issues. 
    • Radiological impact studies for specific regulated contexts.
    • Accidental-release assessments for short-term impact and emergency scenarios.

    Our approach can include emissions inventory and quantification, exposure-pathway analysis, environmental assessment and prospective health-risk evaluation, depending on the study scope.

Why choose us?

We help you reduce operational, regulatory, and reputational risk by providing robust, practical, and defensible insights.
  • More than compliance support
    We do not see regulatory studies as a box-ticking exercise. We use them to clarify impacts, reduce uncertainty and support better decisions.
  • Strong modelling and scientific expertise
    Our teams work on atmospheric dispersion modelling, air quality forecasting, emissions-scenario modelling and 3D atmospheric studies for complex industrial and urban environments.
  • Methods built for defensible results
    Our work is based on structured approaches covering emissions assessment, exposure analysis, environmental assessment and health-risk evaluation.
  • Experience that reduces risk
    Public and internal sources describe Air & Climate entity of SUEZ as combining long-standing air-quality expertise with broad project experience across industrial, public and urban contexts.
