Air Quality Engineer

What Does an Air Quality Engineer Do?

Air quality engineers protect public health and the environment by measuring, modelling, and reducing air pollution. They design air pollution control (APC) systems for industrial facilities, conduct dispersion modelling to predict how pollutants spread through the atmosphere, manage monitoring networks, and ensure compliance with air quality regulations. Their work spans industrial emissions (factories, power plants, refineries), urban air quality (traffic pollution, low-emission zones), and indoor environments.

Air pollution remains Europe’s largest environmental health risk, causing an estimated 300,000 premature deaths annually in the EU. The EU Ambient Air Quality Directive, recently revised with stricter limits aligned with WHO guidelines, the Industrial Emissions Directive (IED), and national Clean Air Strategies are driving sustained demand for air quality professionals. Cities across Europe are expanding low-emission zones and monitoring networks, while industrial operators face tighter permit conditions.

Engineers work for environmental consultancies, industrial companies, air monitoring equipment manufacturers, local and national government environment agencies, and public health organisations. The role requires a blend of engineering design, atmospheric science, regulatory knowledge, and data analysis. European salaries range from EUR 36,000 for graduate air quality consultants to EUR 84,000+ for senior specialists or APC design leads. The field offers diverse career paths spanning monitoring, modelling, control engineering, and policy advisory.

Key Responsibilities

• Conduct air dispersion modelling (AERMOD, ADMS) to assess pollution impacts on receptors
• Design and specify air pollution control equipment (scrubbers, baghouses, SCR/SNCR systems)
• Manage ambient air quality monitoring networks and analyse PM2.5, NOx, SO2, and O3 data
• Prepare environmental permit applications and industrial emissions assessments
• Conduct stack emission testing and continuous emissions monitoring system (CEMS) validation
• Advise clients on compliance with EU Ambient Air Quality Directive and Industrial Emissions Directive

Required Education

• Bachelor’s or Master’s in Environmental Engineering, Chemical Engineering, or Atmospheric Science
• Proficiency in air dispersion modelling software (AERMOD, ADMS, CALPUFF)
• Understanding of EU air quality legislation and industrial emissions regulations
• MCERTS qualified person status for monitoring roles
