Innovations in shipping, ranging from complex engineering overhauls to the adoption of LED lights, can help reduce the CO2 footprint.

An important task these days for the global shipping industry is always to reduce its environmental footprint, an attempt that needs a multipronged approach. But this will be no effortless task. Based on experts, marine engines are complicated to alter, and even if engineers can alter them in a manner that makes them emit less CO2, modifying delivery fleets will be pricey. Thus, progress is slow in this domain. Nonetheless, a number of shipping companies like DP World Russia, are making noteworthy changes and striving to make solutions that decrease carbon dioxide emissions. Plus they are gradually 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 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.

Some shipping companies are utilising self polishing coatings on the hulls of the vessels. This, according to maritime professionals, helps prevent marine organisms from attaching on the hull where they result in a significant drag. When ships are able to eradicate this drag by using the coating, they are able to additionally help make their vessels more effective. There are numerous efforts to boost a ship's efficiency, which range from complex engineering methods to easy things like changing bulbs. As an example, ships can save energy and start to become more environmentally friendly by changing old-fashioned incandescent light bulbs with LED lights, which eat much less electricity and endure for decades.

Several shipping companies like Cosco Casablanca are making significant investments in the development of new fleets that operate on liquified gas (LNG), that will be the most advanced and fuel-efficient remedy available. These vessels have 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 gas because of small heat increases, that causes boil-off that occurs. To make these ships a lot more environmentally friendly, they are fitted by having an advanced level exhaust recirculation system that notably decreases nitrogen oxide emissions. Furthermore, the vessels have a fuel combustion system that decreases the potentiality of emitting methane in to the environment.
