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

An important task these days for the global shipping industry would be to reduce its ecological footprint, an attempt that needs a multipronged approach. But this might be no simple task. Based on specialists, marine engines are complex to improve, and even if engineers can alter them in a way that can certainly make them emit less CO2, modifying shipping fleets is quite expensive. Thus, progress is slow in this domain. However, a range shipping companies like DP World Russia, are making outstanding changes and striving to make solutions that reduce carbon dioxide emissions. Plus they are gradually placing those modifications to work on their fleets of vessels. They are increasingly meeting the benchmark demands of the energy efficiency design index. Indeed, companies like Morocco Maersk are creating efficiency in the commercial shipping sector. A fantastic example of technological progress is seen in the improvement of the Mewis duct. This is a cylindrical channel which includes incorporated fins, which is located in the front of the propeller. As the a ship moves through water, it produces a wake current that may be turbulent and result in power wastage. However, the Mewis duct directs this wake current towards the propeller and streamlines the water movement. Additionally, the fins inside the duct twist the current before it reaches the propeller blades, that leads to increased energy efficiency for the propulsion system.

Some shipping companies are utilising self polishing coatings on the hulls of their vessels. This, in accordance with maritime experts, aids in preventing marine organisms from clinging onto the hull where they result in a significant drag. So when vessels have the ability to eliminate this drag by using the coating, they are able to additionally help make their ships better. There are many different efforts to boost a ship's efficiency, which range from complex engineering answers to easy things such as changing light bulbs. For instance, ships can conserve power and start to become more environmentally friendly by changing old-fashioned incandescent light bulbs with LED lights, which consume less electricity and last for decades.

A few shipping companies like Cosco Casablanca are currently making significant investments in the development of new fleets that run on liquified gas (LNG), which can be the absolute most higher level and fuel-efficient option available. These vessels are equipped with slow-speed tri-fuel engines that run on compressed boil-off gas from the cargo tanks as fuel. During transportation, the LNG changes its state to gas due to slight temperature rises, which in turn causes boil-off to happen. To produce these vessels more environmentally friendly, they have been equipped 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 to the atmosphere.
