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

Some shipping companies are utilising self polishing coatings in the hulls of their ships. This, based on maritime professionals, helps prevent marine organisms from attaching on the hull where they produce a significant drag. When ships are able to eliminate this drag using the this layer, they are able to also help make their ships better. There are many different efforts to enhance a ship's efficiency, which range from complex engineering answers to easy things such as changing lights. As an example, ships can save energy and start to become more environmentally friendly by replacing conventional incandescent light bulbs with LED lights, which eat less electricity and endure for many years.

An essential task these days for the global shipping industry is to reduce its ecological impact, an attempt that will require a multipronged approach. But this might be no easy task. According to experts, marine engines are complex to change, and even if engineers can modify them in a way that is likely to make them emit less CO2, changing shipping fleets would be quite expensive. Thus, progress is sluggish in this domain. Nonetheless, a range shipping companies like DP World Russia, are making impressive changes and striving to make solutions that decrease co2 emissions. And they are gradually putting those modifications to the test on their fleets of vessels. These are typically increasingly meeting the benchmark requirements of the energy efficiency design index. Indeed, businesses like Morocco Maersk are creating effectiveness in the commercial shipping sector. An excellent case of technical progress is visible in the improvement 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 water, it creates a wake current that may be turbulent and result in energy wastage. However, the Mewis duct directs this wake current towards the propeller and streamlines water flow. Furthermore, the fins within the duct twist the current before it reaches the propeller blades, leading to increased energy efficiency of the propulsion system.

Several shipping companies like Cosco Casablanca are making significant investments in the growth of new fleets that operate on liquified natural gas (LNG), which is the absolute most advanced level and fuel-efficient solution available. These vessels are equipped with slow-speed tri-fuel engines that run using compressed boil-off gasoline from the cargo tanks as gas. During transportation, the LNG changes its state to fuel because of slight heat rises, that causes boil-off to occur. To make these vessels even more environmentally friendly, they have been fitted having an advanced level exhaust recirculation system that significantly decreases nitrogen oxide emissions. Additionally, the vessels are equipped with a fuel combustion system that minimises the potentiality of releasing methane to the atmosphere.
