Report Code: SE 3919 Nov, 2023, by marketsandmarkets.com

[205 Pages Report] The global emission monitoring system market size is expected to grow from USD 3.2 billion in 2023 to USD 5.0 billion by 2028, at a CAGR of 9.3% from 2023 to 2028. Manufacturing companies are required to ensure that their pollutant emission rates are within specified limits. To achieve this, countries have issued laws and ordinances that provide detailed instructions for emission control measures. For instance, the Federal Emission Control Act was introduced in Germany, while the United States implemented the Environmental Protection Agency (EPA) Clean Air Act. The concern over hazardous gas emissions has led to an increase in demand for emission monitoring systems that help protect the environment.

Market Dynamics

DRIVERS: Rising emphasis on ambient air quality monitoring

Air quality monitoring for outdoor environments is considered critical in several countries worldwide. Several cities worldwide that have an advanced civic technology environment or those planning major infrastructure upgrades in their existing ones should consider integrating EMS into their infrastructures. Cities with “Smart City” agendas and advanced data management capabilities can measure emissions using these systems. People living in highly polluted towns and cities are realizing the impact of harmful gases and particles. For instance, a European city London faces high air pollution and in minority of the cases the air pollution considered as the proven fatal. Thus, it is becoming necessary to monitor the ambient air quality in major cities to maintain environmental and human health.

RESTRAINTS: High maintenance costs associated with emission monitoring systems

A continuous emission monitoring system (CEMS) is a hardware-based emission monitoring system that collects data with the help of gas analyzers and sensors. Industries require emission monitoring systems that remain operational even in extreme environmental conditions. Manufacturers have to carry out regular or frequent maintenance of continuous emission monitoring systems to keep them working 24 hours a day and obtain a high level of reliability. Depending on the application, continuous emission monitoring systems require maintenance daily, monthly, quarterly, semi-annually, or annually. The maintenance cost of these systems is very high.

OPPORTUNITIES: Growing pharmaceuticals industry

The pharmaceutical industry is rapidly growing worldwide due to an aging population and an increased prevalence of chronic diseases, which drives the demand for prescription drugs. Additionally, advancements in technology within the industry are contributing to its growth. However, the manufacturing processes in pharmaceuticals are complex and involve the use of various chemicals and solvents that can release pollutants such as volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and particulate matter (PM) that can harm the environment. Therefore, the US Environmental Protection Agency (EPA) has recently finalized regulations for controlling emissions of HAPs from pharmaceutical manufacturing facilities. These regulations will require pharmaceutical companies to install and operate emission monitoring systems to monitor and control their emissions.

CHALLENGES: Performance limitations of emission monitoring systems in harsh operating conditions

Emission monitoring systems face technical challenges due to strict regulatory frameworks. These systems need to be maintained and designed to comply with regulations. They operate in harsh environments and extreme conditions such as dust, fog, and rain, making them susceptible to accuracy and performance-related issues.  In various critical industries, including chemicals, petrochemicals, and oil & gas, emission monitoring systems are commonly utilized. However, these systems face challenges in providing precise and dependable data due to the installation of analyzers in hard-to-reach locations. This can cause issues with calibration, maintenance, and replacement of the devices, which may further compound the problems.

Emission Monitoring System Market Ecosystem

Prominent companies in this market include well-established, financially stable manufacturers such as ABB (Switzerland), AMETEK. Inc. (US), Emerson Electric Co. (US), Siemens (Germany), and Thermo Fisher Scientific Inc. (US). These companies have been operating in the market for several years and possess a diversified product portfolio and strong global sales and marketing networks. Along with the well-established companies, there are a large number of startups and small companies operating in this market, such as Gasmet Technologies Oy ( Finland) and Protea Ltd. (UK).

Emission Monitoring System Market by Ecosystem

Hardware segment is expected to hold largest market share during the forecast period.

Emission monitoring systems rely highly on hardware components to collect accurate data on emissions. These components play a vital role in the system’s ability to monitor emissions effectively. Continuous emission monitoring systems (CEMS) function through hardware components, whereas predictive emission monitoring systems (PEMS) are powered by software and use few hardware components such as sensors to predict gas emissions. Gas analyzers, gas sampling systems, flow and opacity monitors, particulate matter monitors, sample probes, sample lines, data controllers, and filters are examples of some hardware components deployed in CEMS. CEMS are used to collect data regarding emissions of gases from various industries, such as power generation, oil & gas, chemicals, building materials, and waste incineration. The increasing number of regulations for pollution monitoring in various industries has led to a rise in demand for CEMS, which, in turn, has boosted demand for hardware components.

The market for PEMS is projected to grow with substantial CAGR during the forecast period.

A PEMS provides continuous data recording and generates reports in accordance with US Environmental Protection Agency (US EPA) regulations. It is an improved version of the emission monitoring system. Moreover, the PEMS software is easy to configure using a non-proprietary user interface. It uses process sensors and mathematical or statistical models to analyze gas concentrations or emission rates. The cost of PEMS is lower than that of CEMS because the preventive emission monitoring system is based on software, thereby eliminating the need for costly sensors and analyzers. However, some PEMS solutions may recommend the use of additional hardware components, such as a data acquisition system (DAS), to improve the accuracy of the predictions.

The market in Asia Pacific is projected to hold the largest market share from 2023 to 2028.
