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

Some shipping companies are utilising self polishing coatings in the hulls of the vessels. This, according to maritime experts, aids in preventing marine organisms from attaching on the hull where they produce 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 methods to easy things such as changing lights. As an example, vessels can conserve energy and start to become more environmentally friendly by replacing traditional incandescent light bulbs with LED lights, which eat much less electricity and endure for many years.

A significant task nowadays for the global shipping industry would be to reduce its environmental impact, an attempt that needs a multipronged approach. But this is certainly no effortless task. Based on experts, marine engines are complicated to improve, and even if engineers can modify them in a way that will make them produce less CO2, altering shipping fleets could be pricey. Hence, progress is slow in this domain. Nonetheless, a number of shipping companies like DP World Russia, are making spectacular changes and striving to make solutions that reduce co2 emissions. Plus they are gradually placing those changes to the test on their fleets of ships. They are increasingly fulfilling 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 seen 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. Nonetheless, the Mewis duct directs this wake current towards the propeller and streamlines the water flow. Additionally, the fins in the duct twist the current before it reaches the propeller blades, leading to increased energy efficiency of the propulsion system.

A few shipping companies like Cosco Casablanca are currently making significant investments within the development of new fleets that operate on liquified propane (LNG), which can be the absolute most advanced and fuel-efficient remedy available. These vessels are equipped with slow-speed tri-fuel engines that run on compressed boil-off gasoline through the cargo tanks as fuel. During transportation, the LNG changes its state to gasoline as a result of slight temperature rises, which in turn causes boil-off that occurs. To create these vessels much more environmentally friendly, they are fitted by having an advanced level exhaust recirculation system that significantly reduces nitrogen oxide emissions. Additionally, the ships include a fuel combustion system that decreases the potential of releasing methane into the atmosphere.
