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

Some shipping companies are utilising self polishing coatings in the hulls of the vessels. This, in accordance with maritime experts, helps prevent marine organisms from attaching onto the hull where they create a significant drag. When vessels have the ability to eradicate this drag utilising the this layer, they are able to additionally make their vessels more effective. There are various efforts to enhance a ship's efficiency, ranging from complex engineering solutions to simple things like changing light bulbs. For instance, vessels can conserve power and start to become more environmentally friendly by changing conventional incandescent light bulbs with LED lights, which consume less electricity and last for many years.

An essential task these days for the global shipping industry is always to reduce its ecological footprint, an effort that requires a multipronged approach. But this might be no easy task. According to specialists, marine engines are complicated to change, and even if designers can alter them in a manner that could make them emit less CO2, changing delivery fleets is very costly. Hence, progress is sluggish in this domain. However, a number of shipping companies like DP World Russia, are making amazing changes and striving to get solutions that reduce co2 emissions. And they are slowly placing those changes to the test on their fleets of ships. They truly are increasingly meeting the benchmark requirements of the energy efficiency design index. Certainly, companies like Morocco Maersk are creating efficiency in the commercial delivery sector. An excellent case of technological progress is visible in the enhancement of the Mewis duct. This is a cylindrical channel that has incorporated fins, which is located in the front of the propeller. As the a ship moves through the water, it produces a wake current which can be turbulent and result in energy wastage. But, the Mewis duct directs this wake current towards the propeller and streamlines the water movement. Furthermore, the fins in the duct twist the current before it reaches the propeller blades, which leads to increased energy efficiency of the propulsion system.

A few shipping companies like Cosco Casablanca are making significant investments in the development of new fleets that run using liquified natural gas (LNG), which will be the most advanced level and fuel-efficient option available. These vessels are equipped with slow-speed tri-fuel engines that run using compressed boil-off fuel from the cargo tanks as fuel. During transportation, the LNG changes its state to fuel due to slight temperature increases, that causes boil-off to occur. To produce these vessels even more environmentally friendly, they are fitted by having an higher level exhaust recirculation system that significantly reduces nitrogen oxide emissions. Also, the ships include a fuel combustion system that decreases the potentiality of releasing methane into the atmosphere.
