Strong efforts have been made on the development of technology that can reduce such emissions effectively. SCR (Selective Catalytic Reduction) technology, using urea solutions as the reduction agents, is considered to be a key technology for abating NOx emissions in the marine sector.

New and stricter emissions legislation have been implemented in the marine sector. Shallow and deep sea vessels, as well as inland vessels, will all be equipped with SCR technology which must be used in Emission Control Areas aiming to minimize airborne emissions from ships.
