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

Several shipping companies like Cosco Casablanca are making significant investments in the development of new fleets that run using liquified gas (LNG), that is the absolute most advanced level and fuel-efficient solution available. These ships have slow-speed tri-fuel engines that run on compressed boil-off fuel through the cargo tanks as fuel. During transport, the LNG changes its state to gasoline due to small temperature increases, which in turn causes boil-off to occur. To make these vessels a lot more environmentally friendly, they have been fitted with an advanced level exhaust recirculation system that considerably decreases nitrogen oxide emissions. Also, the ships have a gasoline combustion system that decreases the potential of emitting methane to the atmosphere.

Some shipping companies are utilising self polishing coatings on the hulls of the ships. This, in accordance with maritime experts, helps in avoiding marine organisms from attaching on the hull where they result in a significant drag. When ships have the ability to eliminate this drag utilising the coating, they are able to also make their ships more effective. There are numerous efforts to boost a ship's efficiency, including complex engineering solutions to easy things like changing bulbs. For instance, ships can conserve energy and start to become more environmentally friendly by changing traditional incandescent LED lights with Light-emitting Diode lights, which eat less electricity and endure for decades.

A significant task these days for the global shipping industry would be to reduce its ecological footprint, an effort that will require a multipronged approach. But that is no simple task. According to specialists, marine engines are complicated to change, and even if designers can alter them in a way that could make them emit less CO2, altering delivery fleets would be very costly. Thus, progress is slow in this domain. However, a range shipping companies like DP World Russia, are making amazing modifications and striving to make solutions that reduce carbon dioxide emissions. Plus they are slowly putting those changes to the test on their fleets of vessels. They have been increasingly fulfilling the benchmark demands of the energy efficiency design index. Certainly, companies like Morocco Maersk are driving effectiveness in the commercial delivery sector. An excellent example of technical progress is seen in the improvement of the Mewis duct. This is a cylindrical channel which has incorporated fins, which is situated in the front of the propeller. As the a ship moves through the water, it creates a wake current which can be turbulent and result in energy wastage. Nevertheless, the Mewis duct directs this wake current towards the propeller and streamlines water movement. Additionally, the fins inside the duct twist the current before it reaches the propeller blades, which leads to increased energy efficiency of the propulsion system.
