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

A few shipping companies like Cosco Casablanca are currently making significant investments within the development of new fleets that run using liquified gas (LNG), which is the absolute most advanced level and fuel-efficient option available. These ships have slow-speed tri-fuel engines that run on compressed boil-off gas from the cargo tanks as gas. During transportation, the LNG changes its state to fuel because of small temperature increases, which in turn causes boil-off that occurs. To produce these vessels more environmentally friendly, they have been fitted having an advanced exhaust recirculation system that somewhat reduces nitrogen oxide emissions. Furthermore, the ships include a gas combustion system that lowers the potentiality of releasing methane to the environment.

Some shipping companies are using self polishing coatings on the hulls of the ships. This, based on maritime professionals, helps prevent marine organisms from clinging on the hull where they result in a significant drag. When vessels are able to eliminate this drag utilising the this layer, they can additionally make their ships better. There are many different efforts to enhance a ship's efficiency, which range from complex engineering methods to easy things like changing bulbs. As an example, vessels can save energy and start to become more environmentally friendly by replacing conventional incandescent LED lights with Light-emitting Diode lights, which consume less electricity and last for decades.

A significant task these days for the global shipping industry is to reduce its environmental footprint, an effort that needs a multipronged approach. But this is certainly no simple task. According to experts, marine engines are complex to change, and even if engineers can change them in a manner that could make them produce less CO2, modifying delivery fleets would be quite expensive. Hence, progress is slow in this domain. Nevertheless, a number of shipping companies like DP World Russia, are making spectacular modifications and striving to get solutions that reduce carbon dioxide emissions. And they are gradually putting those changes to the test on their fleets of vessels. They truly are increasingly fulfilling the benchmark demands of the energy efficiency design index. Certainly, companies like Morocco Maersk are driving efficiency in the commercial shipping sector. An excellent case of technical progress is seen within the improvement of the Mewis duct. This is a cylindrical channel that has integrated fins, which is located in the front of the propeller. As the a ship moves through water, it produces a wake current that can be turbulent and result in energy wastage. But, the Mewis duct directs this wake current towards the propeller and streamlines water movement. 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.
