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

Some shipping companies are using self polishing coatings in the hulls of their ships. This, in accordance with maritime specialists, helps prevent marine organisms from clinging on the hull where they result in a significant drag. When ships are able to eradicate this drag using the this layer, they could also make their ships more effective. There are many efforts to enhance a ship's effectiveness, which range from complex engineering solutions to easy things like changing lights. For instance, vessels can save power and start to become more environmentally friendly by replacing old-fashioned incandescent light bulbs with Light-emitting Diode lights, which eat less electricity and endure for decades.

An essential task nowadays for the global shipping industry is to reduce its environmental impact, an effort that will require a multipronged approach. But that is no simple task. Based on specialists, marine engines are complex to alter, and even if designers can change them in a fashion that can make them produce less CO2, changing delivery fleets would be very costly. Thus, progress is slow in this domain. However, a range shipping companies like DP World Russia, are making remarkable modifications and striving to find solutions that decrease co2 emissions. And they are gradually placing those modifications to work on their fleets of ships. These are typically increasingly fulfilling the benchmark requirements of the energy efficiency design index. Indeed, businesses like Morocco Maersk are creating efficiency in the commercial shipping sector. A great case of technical progress can be seen within the enhancement of the Mewis duct. This is a cylindrical channel which includes integrated fins, that is located 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. 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.

Several shipping companies like Cosco Casablanca are making significant investments within the growth of new fleets that run using liquified natural gas (LNG), that is probably the most advanced level and fuel-efficient remedy available. These vessels include slow-speed tri-fuel engines that run using compressed boil-off gasoline through the cargo tanks as gas. During transport, the LNG changes its state to gasoline because of small heat increases, which in turn causes boil-off to happen. To help make these vessels more environmentally friendly, they have been equipped by having an advanced level exhaust recirculation system that dramatically reduces nitrogen oxide emissions. Also, the ships are equipped with a gas combustion system that minimises the potentiality of emitting methane in to the environment.
