The marine selective catalytic reduction (SCR) systems market is projected to grow steadily between 2025 and 2035, driven by stringent IMO Tier III NOx emission regulations, increasing retrofitting of existing vessels, and rising investments in low-emission marine propulsion technologies. The market is expected to be valued at USD 5,359.5 million in 2025 and is anticipated to reach USD 9,418.6 million by 2035, reflecting a CAGR of 5.8% over the forecast period.
Marine selective catalytic reduction (SCR) systems use a urea based reductant to reduce nitrogen oxide (NOx) emissions from exhaust gases through injection of the reductant into the stream where it interacts with a catalyst.
Meanwhile, increasing pressure to decarbonize international shipping, combined with the rise of hybrid and LNG-fueled vessels, serves to accelerate the deployment of SCR units across commercial, naval, offshore and inland waterways vessels. But space limitations, urea storage logistics, and system integration costs still pose serious barriers to adoption.
Key trends include compact modular SCR units, integration with dual-fuel and LNG engines, remote emissions monitoring and urea consumption optimization systems.
The presence of ECA (Emission Control Area) compliance requirements on USA and Canadian coastlines has been one of the major factors contributing to North America being one of the leading adopters for marine SCR systems. SCR-equipped tugboats, ferries and coastal vessels that cross into IMO Tier III zones are in high demand in the United States.
Canada is also back fitting SCR units on its coastguard and civil fleets. Meanwhile, the region’s push for green maritime corridors and hydrogen-LNG hybrid propulsion systems will bolster further market growth."
Mandates for aggressive emissions reductions, EU Green Deal marine initiatives and emerging clean shipping infrastructure in ports support Europe’s market. SCR systems are being integrated into LNG-powered ferries, Baltic Sea container ships, and ice-class vessels in countries including Germany, Netherlands, Norway, France, and Finland. Government-supported incentives for retrofit programs and urea supply infrastructure development are speeding up adoption throughout inland waterways and short-sea shipping.
Asia-Pacific is the fastest-growing region driven by increasing number of shipbuilding activity, including ECA expansion and adoption of relevant IMO 2020 and Tier III compliance technologies in China, Japan, South Korea, Singapore and India.
China’s Strategy in Decarbonizing Domestic Shipping and Investing in Green Ports Opens Up Opportunities for SCR Manufacturers and Integrators LNG and ammonia-ready ships with SCR on board are already being integrated by the arguably world’s most advanced shipyards both in Japan and South Korea. Retrofitting programs are also proliferating across Southeast Asia.
Challenges
Retrofitting Complexity, Operational Costs, and Space Limitations
Retrofitting SCR systems into older ships with space-limited engine rooms is cost-prohibitive and complex. Operational barriers are also caused by urea logistics, especially for long-haul voyages, and maintenance requirements for catalysts and dosing systems. The pressure to implement NOx limits in some geographies outside the ECA is delayed as there is no standard global enforcement for all regions.
Opportunities
Green Shipping Mandates, Modular SCR Systems, and Engine Integration
Further opportunities exist for modular SCR designs that enable easy retrofit and low-space footprint, as well as dual-fuel and hybrid propulsion compatibility. The emerging incentives for carbon-neutral shipping corridors & scalable expansion of urea bunkering, alongside decarbonisation frameworks such as those led by IMO for GHG quantity reduction, will spur demand for integrated systems to control emissions.
Yards that provide factory-fitted SCR packages, which include remote diagnostics and urea optimization tools, are also expected to be in a better position to compete.
Marine selective catalytic reduction (SCR) systems market from 2020 to 2024 continued to grow and the factors driving it include IMO Tier III NOₓ emission regulations that have taken effect in Emission Control Areas (ECAs), growing pressure to decarbonize shipping and an increase in both new builds and retrofits.
SCR systems became the technology of choice for diesel-powered shipping lines with emissions targets, especially in LNG carriers, container ships and ferries. However system complexity, urea logistics, high capital costs and integration into existing engine platforms limited uptake across smaller fleets and older vessels.
Go in the 2025 to 2035 time frame the market will evolve with integration into hybrid propulsion systems, real-time emissions monitoring and AI-optimised dosing systems. As vessel designs move towards future-proof propulsion, SCR technology will evolve to work with alternative fuels such as methanol, ammonia and biofuels.
Other factors driving demand will include green shipping corridors, carbon taxation policies and fleet digitalization. SCR units become compact and modular; smart urea management; blockchain-backed emissions compliance tracing; all become widespread, especially in retrofitted tonnage and coastal vessels entering Tier III zones.

Commercial Application Market Share (2025)
| Commercial Vessel Type | Value Share (%) |
|---|---|
| Containers | 38.2% |
The marine selective catalytic reduction (SCR) systems market for commercial applications is estimated to be dominated by container vessels in 2025, with a value share of 38.2% As the international shipping sector faces more stringent regulatory pressure to cut NOx emissions, container ships as high-frequency, long-haul carriers are leading the SCR pack.
By implementing SCR systems on container vessels, compliance with the International Maritime Organization (IMO) Tier III regulation is guaranteed in emission control areas (ECA). These vehicles are well-suited for the SCR technologies due to operation at high engine loads and fuel volumes, where catalytic conversion of NOx emissions is the most effective method.
With global demand for sustainable logistics and land based e-commerce driven containerized freight continuing to grow, shipbuilders and fleet operators are focusing increasing attention on retrofitting and constructing new vessels with cutting-edge SCR systems to reduce emissions. Such developments further reinforce the container vessel segment's position at the top for the commercial marine SCR market.
Offshore Application Market Share (2025)
| Offshore Vessel Type | Value Share (%) |
|---|---|
| AHTS | 41.7% |
By 2025, Anchor Handling Tug Supply (AHTS) vessels are expected to constitute the largest share of the offshore segment in the marine SCR systems market, with a value share of 41.7%. These vessels are critical to offshore oil and gas operations and operate in high-load conditions and require rugged emission control with reliable performance in challenging environments.
As AHTS vessels are designed to perform heavy towing, anchor handling and supply operations, they are particularly burdened during operation with NOx emissions, thus prime candidates for SCR integration. Over time, their continued activity, particularly in regulated areas (e.g., North Sea and USA Gulf regions), has driven the adoption of the SCR system.
Increasing attention to environmentally sustainable offshore exploration along with emission caps for offshore support vessels market are driving operators towards investing in robust and efficient SCR solutions. Offshore energy operations have been around for many years and are still expanding for global market developments, which gives rise to demand for AHTS vessels, which is the main application responsible for growth in the offshore marine SCR systems market.
Driven by stricter IMO Tier III emissions legislation, stronger need to decarbonize marine transport, and higher deployment of aft treatment solutions across commercial vessels, offshore support vessels, and naval fleets, the marine SCR systems market is growing at a steady pace.
NOx reduction is achieved through the use of SCR systems that inject a urea-based reductant into combustion exhausts and utilize catalyst beds. Market drivers include meeting evolving global emission standards, retrofit opportunities, increasing LNG and hybrid propulsion integration, and port authority incentives for low-emission vessels.
