Why Does Scrubbers Dominate the Global Air Quality Control Systems Market?

The scrubbers segment is expected to account for 42.0% of the global air quality control systems market share in 2026. Many hazardous gases and particulate matter such as sulfur dioxide (SO₂), nitrogen oxides (NOx), acid gases and fine dust can be successfully removed using very simple wet or dry chemical scrubbers. Their capacity to handle many pollutants at once makes them very desirable in sectors such as power generation, chemicals and manufacturing, where emission profiles are complicated and regulatory compliance is rigorous.

On March 26, 2025, Value Maritime completed installation of its 15-MW Filtree Exhaust Gas Cleaning System (EGCS) on the tanker Nexus Victoria owned by Mitsui O.S.K. Lines (MOL). The scrubber removes sulfur compounds and ultrafine particulate matter while simultaneously capturing up to 10% of CO₂ emissions, demonstrating how modern scrubbers are evolving into multi-pollutant control platforms.

The power generation segment is expected to account for 35.0% of the global air quality control systems market share in 2026. Thermal power plants, particularly coal- and oil-fired, are major sources of sulfur dioxide (SO₂), nitrogen oxides (NOx), particulate matter, and mercury emissions due to their steady-state operations, making them the prime target of air quality control systems to comply with stringent environmental emission standards.     

On November 19, 2025, NTPC commissioned the FGD system at its Mouda thermal power station in Maharashtra, enabling removal of sulfur dioxide (SO₂) from coal combustion exhaust gases. The project was highlighted because visible emissions were significantly reduced, and gypsum generated from the scrubber process is being supplied to cement manufacturers. (Source: Times of India)

Market Drivers

Strict environmental regulations (EPA, EU directives, India CPCB norms)

The air quality control systems market is a key driver of the Environmental Protection Agency (EPA), European Union industry guidelines and India’s Central Pollution Control Board (CPCB). The restrictions place strict limitations on the industrial emissions of pollutants including SO₂, NOx, particulate matter and dangerous gases and force industries like power, cement, steel and chemicals to implement sophisticated pollution control equipment. The steady tightening of air quality regulations, together with required compliance reporting and penalties for non-compliance, has led to a large increase in the installation of scrubbers, electrostatic precipitators and other emission control devices around the world.

On June 11, 2025, the U.S. Environmental Protection Agency (EPA) initiated a major review of greenhouse-gas and air-pollution regulations for fossil-fuel power plants under the Clean Air Act. The proposal triggered compliance assessments across utilities and industrial operators, reinforcing the importance of emission-monitoring, scrubber, and pollution-control technologies even as companies evaluated potential regulatory changes.  (Source: Environmental Protection Agency)

Rising industrial emissions globally

One of the major factors driving the air quality control systems market growth is the growing industrial emissions worldwide. The fast-growing industries such as power generation, manufacturing, chemicals, cement, and steel production are releasing harmful pollutants into the atmosphere. Increased urbanization and infrastructure development, especially in emerging nations, have resulted in higher energy demand and industrial output, which, in turn, have led to increasing emissions of particulate matter, sulfur oxides, nitrogen oxides and volatile organic compounds. The growing pollution load has produced an urgent need for sophisticated air pollution control systems to meet regulatory requirements, safeguard the public’s health and minimize damage on the environment.

On April 10, 2025, China expanded its national emissions trading system (ETS) to include the steel, cement, and aluminum smelting sectors, bringing more than 1,300–1,500 additional high-emitting industrial facilities under emissions regulation. The move reflects the scale of industrial emissions from these sectors and the government's effort to control growing pollution from heavy manufacturing.

Emerging Trends

• Rapid adoption in emerging economies with industrial expansion: Countries in Asia Pacific, including India, China, Vietnam, and Indonesia are witnessing strong adoption due to fast industrialization and growing pollution levels. Governments are seeking to tighten emission limits and driving industry to either upgrade or construct innovative air pollution control systems.
• Retrofit and modernization of aging industrial infrastructure: Several industrial sectors in North America and Europe are not establishing new manufacturing facilities but are upgrading existing facilities with modern air control systems such as advanced electrostatic precipitators and high-efficiency scrubbers to meet the revised environmental standards.

Why is Asia Pacific a Strong Market for Air Quality Control Systems?

Asia Pacific is expected to account for a market share of 37.0% in 2026. Coal intensive power production and large scale industrial clusters are major drivers for the air quality control systems market in Asia Pacific, especially in China and India where emissions from steel, cement and chemical industry still remain high. For instance, China’s ultra-low emission retrofits in coal-fired power plants, and India’s installation of flue gas desulfurization (FGD) systems in NTPC plants have tremendously raised the demand for scrubbers and ESP systems. Japan and South Korea also contribute through advanced semiconductor and car production facilities that require high-precision air filtering systems. On February 18, 2026, ERG and Neev Fluidex launched the ERG Neev joint venture to supply air pollution control and odor-control systems throughout India and Asia Pacific. The partnership focuses on scrubbers, VOC treatment systems, carbon filtration, and industrial air pollution control technologies for the wastewater, pharmaceutical, chemical, and energy sectors.  (Source: H2O Global News)

Why Does the North America Air Quality Control Systems Market Exhibit High Growth?

North America is projected to account for 22.0% of the global air quality control systems market and is expected to register the fastest growth. Demand in North America is fueled by tight EPA compliance mandates, especially the Clean Air Act, driving renovations at older coal and gas power facilities. For example, U.S. utilities in states such as Ohio and West Virginia have implemented wet scrubbers and selective catalytic reduction (SCR) systems to meet SO₂ and NOx regulations. Oil sands operations in Alberta, Canada also implement complex emission control systems to mitigate the high levels of sulfur and particle emissions associated with extraction and processing activities. On November 10, 2025, the government of Canada allocated USD 186 million in 2025 budget funding to support emissions reduction and clean-air initiatives for SMEs and industrial operators. This funding is indirectly increasing the adoption of industrial scrubbers, filtration systems, and emission-control upgrades across Canadian manufacturing facilities. (Source: Government of Canada)

Global Air Quality Control Systems Market Outlook for Key Countries

Why is China Emerging as a Major Hub in the Air Quality Control Systems Market?

China is the major demand driver because to rigorous industrial emission reduction programs such as Blue Sky Protection Campaign that required steel hubs such as Hebei and Tangshan to construct high efficiency desulfurization and dust collecting systems. The large coal-fired power stations of businesses such as Huaneng Group have installed ultra-low emissions retrofits with the combination of ESPs, bag filters and wet scrubbers.
