An Emission Monitoring System (EMS) is a combination of hardware and software designed to measure and analyze pollutants emitted from industrial processes. These systems track gases such as sulfur dioxide (SO₂), nitrogen oxides (NOx), carbon dioxide (CO₂), carbon monoxide (CO), particulate matter, volatile organic compounds (VOCs), and mercury. The data is then stored and managed through Data Acquisition and Handling Systems (DAHS) for compliance and reporting.
The global emission monitoring system market was valued at USD 3.44 billion in 2024 and is projected to reach USD 8.29 billion by 2033, growing at a CAGR of 9.85%. This growth is largely driven by tightening environmental regulations, increasing public awareness of air pollution, and rising investments in monitoring air quality across urban and industrial regions.
