According to Fortune Business Insights, the global flue gas desulphurization system market size was valued at USD 23.09 billion in 2025. The market is projected to grow from USD 24.56 billion in 2026 to USD 40.32 billion by 2034, exhibiting a CAGR of 6.39% during the forecast period. Flue gas desulphurization (FGD) systems are critical technologies used to remove sulfur dioxide (SO2) emissions from exhaust flue gases generated by fossil-fuel power plants and industrial processes. The growing need to reduce air pollution and comply with stringent environmental regulations is significantly driving the demand for FGD systems globally.
The increasing awareness regarding environmental sustainability, coupled with rising government initiatives to curb harmful emissions, is boosting market growth. Power generation industries, especially coal-based plants, are major adopters of FGD systems as they seek to minimize their environmental footprint. Additionally, rapid industrialization in emerging economies is contributing to increased deployment of these systems.
The flue gas desulphurization system market is primarily driven by strict environmental regulations aimed at reducing sulfur emissions. Governments across regions have implemented stringent emission norms for power plants and industrial facilities, compelling operators to install FGD systems. The rising demand for cleaner energy production and sustainable industrial operations is further accelerating market growth.
Another key driver is the increasing dependency on coal-based power generation in developing economies. Despite the global shift towards renewable energy, coal remains a significant energy source in several regions, thereby sustaining the demand for emission control systems.
