The global emission monitoring systems (EMS) market was valued at USD 3.28 billion in 2022 and is projected to grow at a CAGR of 9.78% from 2023 to 2032. The market's expansion is driven by tightening environmental regulations, increasing awareness regarding air quality, and industrial demands for pollution control. Governments and regulatory bodies worldwide are implementing strict emission norms, which in turn are boosting demand for both continuous and predictive emission monitoring systems across industries such as power generation, oil & gas, and manufacturing. Emission Monitoring Systems (EMS) are integrated systems used to continuously or periodically collect, analyze, and report data on pollutant emissions from industrial processes. They are essential for ensuring compliance with environmental regulations and assessing the environmental impact of operations.
EMS solutions are mainly categorized into:
-
Continuous Emission Monitoring Systems (CEMS) – Real-time tracking and reporting of pollutants.
-
Predictive Emission Monitoring Systems (PEMS) – Use predictive modeling and software algorithms to estimate emissions based on process parameters.
Historical Growth and Evolution
Initially developed to comply with regulatory reporting requirements, EMS have evolved with technological advances in sensors, data analytics, and IoT integration. Their use has broadened from high-emission sectors like coal and thermal power to encompass diverse industries, including cement, chemicals, and marine. The integration of AI and cloud-based data storage has further enhanced the functionality and efficiency of modern EMS.
