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

Some shipping companies are using self polishing coatings on the hulls of their ships. This, according to maritime experts, aids in preventing marine organisms from attaching onto the hull where they result in a significant drag. So when ships are able to eliminate this drag by using the coating, they can also make their vessels more effective. There are numerous efforts to enhance a ship's efficiency, ranging from complex engineering solutions to easy things such as changing lights. As an example, ships can save energy and start to become more environmentally friendly by changing old-fashioned incandescent LED lights with LED lights, which consume less electricity and endure for many years.

A few shipping companies like Cosco Casablanca are currently making significant investments within the growth of new fleets that operate on liquified natural gas (LNG), that is the most higher level and fuel-efficient remedy available. These ships are equipped with slow-speed tri-fuel engines that run using compressed boil-off gasoline from the cargo tanks as fuel. During transport, the LNG changes its state to gasoline due to small temperature increases, which in turn causes boil-off to happen. To create these vessels a lot more environmentally friendly, they are equipped with an higher level exhaust recirculation system that notably reduces nitrogen oxide emissions. Furthermore, the ships have a gasoline combustion system that minimises the potentiality of releasing methane to the atmosphere.

An essential task nowadays for the global shipping industry is always to reduce its environmental impact, an effort that needs a multipronged approach. But that is no simple task. In accordance with experts, marine engines are complex to improve, and even if engineers can change them in a way that could make them emit less CO2, altering delivery fleets will be very costly. Thus, progress is slow in this domain. However, a range shipping companies like DP World Russia, are making noteworthy changes and striving to find solutions that decrease co2 emissions. Plus they are gradually putting those changes to the test on their fleets of vessels. They are increasingly meeting the benchmark needs of the energy efficiency design index. Certainly, businesses like Morocco Maersk are driving efficiency in the commercial shipping sector. A great case of technological progress can be seen within the improvement of the Mewis duct. This is a cylindrical channel which has incorporated fins, that will be located in the front of the propeller. As the a ship moves through the water, it produces 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 the water flow. Also, the fins in the duct twist the current before it reaches the propeller blades, that leads to increased energy efficiency for the propulsion system.
