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

A few shipping companies like Cosco Casablanca are currently making significant investments in the growth of new fleets that run using liquified natural gas (LNG), that is probably the most higher level and fuel-efficient solution available. These ships include slow-speed tri-fuel engines that run using compressed boil-off fuel through the cargo tanks as fuel. During transportation, the LNG changes its state to gasoline as a result of small heat rises, which in turn causes boil-off to happen. In order to make these vessels even more environmentally friendly, they are fitted by having an higher level exhaust recirculation system that somewhat reduces nitrogen oxide emissions. Additionally, the ships include a gasoline combustion system that lowers the potentiality of emitting methane in to the environment.

An important task nowadays for the global shipping industry would be to reduce its environmental footprint, an effort that needs a multipronged approach. But this is certainly no simple task. In accordance with specialists, marine engines are complicated to change, and even if engineers can modify them in a way that is likely to make them emit less CO2, altering shipping fleets will be very costly. Hence, progress is slow in this domain. However, a number of shipping companies like DP World Russia, are making noteworthy modifications and striving to get solutions that decrease co2 emissions. And they are gradually putting those changes to work on their fleets of ships. They are increasingly meeting the benchmark demands of the energy efficiency design index. Certainly, businesses like Morocco Maersk are creating effectiveness in the commercial delivery sector. A great example of technological progress can be seen in the enhancement of the Mewis duct. This is a cylindrical channel which includes incorporated fins, that is situated in the front of the propeller. As the a ship moves through the water, it produces a wake current that can be turbulent and result in power wastage. But, the Mewis duct directs this wake current towards the propeller and streamlines water flow. Moreover, the fins inside the duct twist the current before it reaches the propeller blades, which leads to increased energy efficiency for the propulsion system.

Some shipping companies are utilising self polishing coatings on the hulls of their ships. This, in accordance with maritime professionals, helps in avoiding marine organisms from attaching 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 effectiveness, including complex engineering answers to simple things such as changing lights. For example, ships can conserve power and start to become more environmentally friendly by replacing traditional incandescent LED lights with LED lights, which consume less electricity and endure for decades.
