Air Quality assessment and planning

Before appropriate measures can be taken to curb relevant air emissions an accurate assessment of the current situation is required. VITO offers different air quality assessment and planning tools to model high resolution air quality maps down to street level.


Our experts provide policymakers with the scientific evidence required to make the best choices to improve air quality. This evidence is based on a detailed analysis of the current situation and future policy scenarios.

VITO offers the ATMO-Street model to derive high-resolution air quality maps down to the street level for air quality assessments and planning.

This model chain is integrated into a user-friendly ATMO-Plan tool harmonizing air quality modelling for planning and environmental impact assessments.

Air Quality Assessment and Planning Tools

ATMO-Plan is a web-based software application to assess the impact of emission reductions on pollutant concentrations.

ATMO-Street is a combination of modelling techniques ranging for the regional to the local scale used to create high-resolution air pollution maps. T

QUARK (Quick Urban AiR quality using Kernels) is a modelling approach developed for the fast calculation of urban air quality assessments at a high spatial resolution.  

To study the impact of local AQ measures taken at street level (noise barriers, screens, urban vegetation, varying building configurations,…) VITO uses tailored Computational Fluid Dynamics (CFD) models.

Other products and services

Effective air quality management heavily relies on the availability and the accuracy of emission datasets. At VITO a dedicated team of emission modelling experts covers all the relevant sectors. We ensure the highest quality of emission data for various types of application domains.

VITO supports different industries to better understand, analyse and mitigate the air pollution challenges they face. Many industrial sites are complex environments with multiple possible sources. The influence of the buildings on the air flows requires micro-scale modelling of the pollutant dispersion.
