Air Quality

Supporting clean air for everyone

A sector that is all around us

Air quality professionals work to improve air quality and reduce pollution in ambient and indoor environments. This can include monitoring, modelling, assessing, reporting, and taking measures to improve air quality. This involves understanding the pollutants and emissions that impact air quality, with the aim of protecting human and environmental health.  

The IES is the home of the Institute of Air Quality Management (IAQM), the professional body for air quality professionals.  

An air quality specialist in an urban setting

Your air quality professional body

The IAQM is led by an elected Committee and has its own competency-based membership grades and tailored CPD opportunities, supporting expertise and excellence in the field.

Through the IAQM, air quality professionals develop the industry standard technical guidance, champion professionalism in the field, and collaborate with other IES communities on cross-cutting topics.
