How it works

About this service

 Stack Emission Monitoring 

Stack emission monitoring is a vital practice in modern industries, aimed at assessing and controlling the release of pollutants into the atmosphere. As the global focus on environmental sustainability intensifies, the need to accurately measure and manage emissions becomes paramount. This page explores the significance of stack emission monitoring, its methodologies, benefits, challenges, and its crucial role in maintaining air quality and protecting the environment.

Stack emission monitoring involves the continuous or periodic measurement of pollutants emitted from industrial processes through chimneys or stacks. These pollutants can range from gases like sulphur dioxide (SO2), nitrogen oxides (NOx), and volatile organic compounds (VOCs) to particulate matter (PM) and heavy metals.

Why Carry Out Stack Emission Monitoring & Testing?

The primary goal of monitoring is to ensure compliance with the limits set in part A1, A2 and part B permits, but its also important:

  • To comply with the limits specified in WID and LCPD.
  • For the calibration of CEMs.
  • To show you how well your abatement systems are working.
  • For your environmental management system.
  • To allow your company to field complaints.


The importance of stack emission monitoring can be summarized in several key points:

Air Quality Improvement: Monitoring helps identify and address sources of pollution, leading to reduced emissions and improved air quality in surrounding areas.

Public Health Protection: By controlling emissions of harmful substances, monitoring contributes to the prevention of respiratory diseases and other health issues among populations living near industrial facilities.

Environmental Compliance: Regulatory agencies enforce emission limits to prevent environmental degradation. Monitoring ensures that industries adhere to these limits, minimizing their impact on the environment.

Data-Driven Decision-making: Accurate emission data enables industries and regulatory bodies to make informed decisions regarding pollution control measures, process optimization, and sustainable practices.

Methodologies for Stack Emission Monitoring:

Several methodologies are employed in stack emission monitoring to measure a wide array of pollutants:

Continuous Emission Monitoring Systems (CEMS): CEMS utilize gas analysers, particulate matter monitors, and flow meters to continuously measure pollutant concentrations in stack emissions. These systems provide real-time data for immediate action.

Periodic Manual Sampling: Sample collection from stack emissions is periodically performed, followed by laboratory analysis. This method is useful for specific pollutants that may not be continuously emitted.

Remote Sensing Technologies: Infrared cameras, laser-based systems, and satellite sensors are used for remote detection and quantification of emissions, providing a broader view of emissions over a larger area.

Why choose Synergy for Stack Emission Monitoring

Stack Emission Monitoring impingers

Our MCERTS Level 2 staff have about 40 years of experience in stack emission monitoring. During that time, we have measured from a vast range of industries and processes.  As a result, we have a wealth of knowledge in the field. Our stack testing service can measure all of the major pollutants. These include particulates, volatile organic compounds, acid gases, combustion gases, Metals, dioxins, and furans. 

We pride ourselves in being friendly people to work, but that doesn’t mean we are unprofessional. From your first inquiry to the final report, we provide a service second to none. We work hard for our clients to make sure that we fully understand their goals and deliver them on time.

Stack Emission Monitoring Reports

Our reports contain all of the details required by the MCERTS format. Furthermore, our reports include each step that we use to obtain the test result. So we show all of the measurements taken on-site and the results from the analysis of the samples. For this reason, all of our work is easy to check for the end-user.

Often the sample points do not comply with the test standard. For this reason, we also give a full list of how to improve the sampling in the future.

Our standard report turnaround is 15 working days from the end of the site work. We can send them in either PDF or hard copy format. Please contact us for an example.

Quality in Monitoring.

Accurate and robust stack emission testing starts with good access to correctly positioned ports. So, if your stack doesn’t already have access ports, read our Port and Platform Advice Note. 

Further information is available below.

Further advice is available in Environment Agency Guidance note M1 – sampling requirements for monitoring. Use of the right methods and sampling procedures is vital in emission monitoring. To ensure correct, robust and repeatable results, we only use the methods specified by The Environment Agency. They detail these in their document Technical Guidance M2.
