Standardised pollutant measurements to meet the requirements of current and future air quality regulations

Air pollution is responsible for around 400,000 premature deaths and €330-€949 billion in health-related costs each year in Europe. In an effort to protect citizens’ quality of life, limits on air pollutants are continually becoming more stringent, and limits continue to be introduced for previously unregulated pollutants. However, the necessary framework of standardised measurement methods to meet these requirements is not fully in place.


This project will use results from EMRP project ENV60 IMPRESS to address this measurement gap by developing measurement methods for newly regulated pollutants, such as ammonia and hydrogen fluoride, address the lack of uncertainty characterisation in flow measurements and develop next-generation techniques for increasingly-stringent pollution limits.

The results will enable regulators, process plant operators, manufacturers and measurement service providers to comply with emission limits and monitoring requirements, supporting efforts to ensure cleaner air across Europe for the benefit of public health and the environment.
