The global emission monitoring system (EMS) market size is expected to reach USD 4.5 billion by 2027 from USD 3.0 billion in 2022, growing at a CAGR of 8.8%. The market growth is mainly attributed to high dependency of countries worldwide on coal-fired power plants to generate electricity, stringent emission norms and standards enforced by North American and European governments, and increased need for environmental protection are the key driving factors for the EMS market.
Hardware accounted for the largest share of EMS market in 2021. Hardware components plays a vital role in the emission monitoring system to collect emissions data. The CEMS functions through its hardware components, whereas the PEMS is a software-powered system and uses hardware components like sensors to predict gas emissions. Hardware devices are used in both CEMS and PEMS to collect emissions data. Hardware-based continuous emission monitoring systems boost the demand for hardware devices as the majority of plants have installed continuous emission monitoring systems.

The continuous emission monitoring system (CEMS) is expected to hold the largest share of EMS market during the forecast period. A continuous emission monitoring system is a complete solution that calculates an emission rate using pollutant analyzer measurements and a conversion equation, graph, or computer program to produce results regarding permissible emission levels. CEMS are used for collecting data regarding emission levels of gases from various industries, such as power generation, oil & gas, chemicals, and waste incineration. Moreover, an increase in the number of stringent rules and regulations regarding pollution monitoring across industries is expected to create demand for CEMS.
The chemicals, petrochemicals, refineries, and fertilizers industry to grow at the highest CAGR during the forecast period. The chemical plants emit gases such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated greenhouse gases (GHGs). Emission monitoring systems are designed to monitor corrosive gases in extreme applications. In chemical plants, emission monitoring systems are used to perform an elemental analysis of fuels to determine the grade and quality of the fuel extracted. Companies are installing emission monitoring systems to monitor gas concentrations at elevated pressures and temperatures.
APAC is expected to hold the largest share of EMS market during the forecast period. China and India are the major contributors to the EMS market growth in APAC. It can also be attributed to the growing power generation and chemicals-use industries, which are the key users of emission monitoring systems, in the region. Moreover, the increasing capacities of coal-fired power plants is another reason for the growing demand for emission monitoring systems. COVID-19 forced lockdowns across APAC. Supply chains in and around APAC were disrupted owing to only limited permissible transportation. Under lockdown, Asian countries suffered tremendous loss of business and revenue due to the shutdown of many manufacturing units.
