According to a research report published by Spherical Insights and Consulting, the global flue gas treatment systems market size was worth around USD 82.69 billion in 2024 and is predicted to grow to around USD 150.84 billion by 2035 with a compound annual growth rate (CAGR) of 5.62% from 2025 to 2035. The flue gas treatment systems market is primarily growing due to increasingly stringent environmental regulations on industrial emissions, rising public awareness of air quality concerns, and ongoing industrialization in emerging economies. 

Market Overview

The Global Flue Gas Treatment Systems Market Size refers to technologies and equipment designed to remove harmful pollutants, such as sulfur dioxide, nitrogen oxides, and particulate matter, from industrial exhaust gases before they are released into the atmosphere. These systems are essential across a wide range of industries, including power generation, cement manufacturing, and chemical processing. The market is primarily driven by increasingly stringent environmental regulations worldwide, such as the U.S. Clean Air Act and the European Industrial Emissions Directive, which mandate lower emissions to improve air quality and public health. Other key drivers include growing industrialization, particularly in the Asia Pacific region, and rising awareness of air pollution's environmental and health impacts.

In July 2025, India’s Ministry of Environment, Forest and Climate Change (MoEF&CC) revised 2015 emission standards, mandating flue gas desulphurisation (FGD) systems only for coal-fired plants within 10 km of major cities, critically polluted areas, or using high sulphur imported coal. The update is expected to cover 79% of thermal facilities, reduce generation costs by 25-30 paisa/kWh, and cut sulfur dioxide emissions. Opportunities in the market stem from technological advancements, such as the integration of IoT for real-time emission monitoring, and the growing focus on sustainable solutions such as Carbon Capture and Storage (CCS) technologies. Major players, including GEA, Babcock & Wilcox, Mitsubishi Hitachi, Thermax, FLSmidth, Alstom, Ducon, and Doosan Lentjes, provide advanced flue gas treatment solutions for regulatory compliance.
