Marine Scrubber Market To Reach 20 Billion US Dollars By 2031 With New Emission Rules

14th April 2025

Ships are vital for global trade, transporting goods across oceans. Their engines, however, emit significant exhaust gases. Marine scrubbers and exhaust gas cleaning systems are used to reduce these emissions. The marine scrubber market includes the production, installation, and maintenance of these systems.

According to Allied Market Research, the market was valued at $4.9 billion in 2021 and is projected to reach $20.3 billion by 2031, growing at a CAGR of 16.2%. Stricter global environmental regulations, especially in Europe and North America, are driving demand for cleaner technologies and emission control systems.

In the U.S., the EPA enforces major environmental laws like the Clean Air Act and the Pollution Prevention Act, focusing on reducing hazardous air pollutants. By technology, wet scrubbers accounted for nearly 90% of the market in 2021 and are expected to remain dominant, driven by strict emission standards. However, dry scrubbers are projected to grow fastest, at a CAGR of 22.6%, due to rising demand in Asia-Pacific, North America and Europe.

By application, bulk carriers held the largest share in 2021, as they transport key raw materials like coal and grain. The cruise segment, focused on passenger comfort and entertainment, is expected to grow fastest at a 21.0% CAGR through 2031. The Protea 2000 emissions monitoring system is approved for the analysis of exhaust gases from the engines and boilers of ships and offshore rigs. Robust and with proven reliability, up to six gases can be measured including SO₂, CO₂ and NO_x.
