<p>The global marine selective catalytic reduction systems market was valued at USD 5.6 billion in 2024 and is estimated to grow at a CAGR of 5.7% from 2025 to 2034. These are advanced emission control technologies designed to reduce nitrogen oxides (NOx) from marine engine exhaust gases. These systems use a catalytic converter and a urea-based reagent to facilitate a chemical reaction that converts NOx into harmless nitrogen (N?) and water vapor (H?O). Marine SCR systems are widely used to meet stringent environmental regulations, such as the International Maritime Organization's (IMO) Tier III standards, ensuring compliance while minimizing the environmental impact of marine operations.<br width=): failed to open stream: No such file or directory

Marine Selective Catalytic Reduction Systems Market Size
The global marine selective catalytic reduction systems market was valued at USD 5.6 billion in 2024 and is estimated to grow at a CAGR of 5.7% from 2025 to 2034. These are advanced emission control technologies designed to reduce nitrogen oxides (NOx) from marine engine exhaust gases.

Marine SCR systems are widely used to meet stringent environmental regulations, such as the International Maritime Organization's (IMO) Tier III standards, ensuring compliance while minimizing the environmental impact of marine operations.
Rising global initiatives to combat climate change are pushing ports to expedite their zero-emission goals. For instance, in 2022, the Ports for People campaign under Pacific Environment introduced the P4P RePORT Cards initiative to evaluate ports' advancements toward zero-emission shipping. These efforts to reduce emissions will drive demand for port equipment and increase the adoption of advanced emission control technologies reduction (SCR) systems to minimize exhaust emissions.
