Integrating advanced exhaust recirculation systems is considerably reducing nitrogen oxide emissions.

Some shipping companies are using self polishing coatings on the hulls of their vessels. This, in accordance with maritime specialists, aids in preventing marine organisms from latching onto the hull where they cause a significant drag. When vessels are able to eliminate this drag utilising the this layer, they could also help make their vessels better. There are numerous efforts to enhance a ship's efficiency, including complex engineering answers to simple things like changing lights. For example, ships can conserve power and start to become more environmentally friendly by replacing traditional incandescent LED lights with Light-emitting Diode lights, which consume less electricity and endure for many years.

A few shipping companies like Cosco Casablanca are currently making significant investments within the growth of new fleets that operate on liquified natural gas (LNG), that will be probably the most advanced and fuel-efficient option available. These vessels are equipped with slow-speed tri-fuel engines that run using compressed boil-off gasoline from the cargo tanks as gas. During transportation, the LNG changes its state to gas as a result of slight heat increases, which causes boil-off that occurs. To produce these ships much more environmentally friendly, they are fitted by having an advanced exhaust recirculation system that somewhat decreases nitrogen oxide emissions. Additionally, the vessels are equipped with a fuel combustion system that lowers the potential of emitting methane into the environment.

An important task these days for the global shipping industry would be to reduce its ecological footprint, an attempt that needs a multipronged approach. But this is no simple task. According to specialists, marine engines are complex to improve, and even if engineers can alter them in a way that could make them emit less CO2, modifying shipping fleets is quite expensive. Thus, progress is slow in this domain. However, a range shipping companies like DP World Russia, are making noteworthy changes and striving to get solutions that decrease carbon dioxide emissions. Plus they are gradually placing those modifications to work on their fleets of vessels. They are increasingly fulfilling the benchmark demands of the energy efficiency design index. Indeed, businesses like Morocco Maersk are driving efficiency in the commercial delivery sector. An excellent example of technical progress can be seen within the enhancement of the Mewis duct. This is a cylindrical channel that has incorporated fins, that will be situated in the front of the propeller. As the a ship moves through water, it creates a wake current that can be turbulent and result in energy wastage. But, the Mewis duct directs this wake current towards the propeller and streamlines the water flow. Additionally, the fins inside the duct twist the current before it reaches the propeller blades, that leads to increased energy efficiency for the propulsion system.
