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

Some shipping companies are using self polishing coatings on the hulls of the ships. This, according to maritime professionals, helps in avoiding marine organisms from attaching onto the hull where they produce a significant drag. When ships have the ability to eliminate this drag by using the this layer, they could also make their ships more efficient. There are various efforts to boost a ship's efficiency, ranging from complex engineering methods to simple things such as changing bulbs. For instance, vessels can save power and start to become more environmentally friendly by replacing old-fashioned incandescent light bulbs with Light-emitting Diode lights, which eat less electricity and last for many years.

An important task these days for the global shipping industry is to reduce its ecological footprint, an attempt that requires a multipronged approach. But this will be no effortless task. In accordance with experts, marine engines are complicated to change, and even if designers can modify them in a manner that is likely to make them produce less CO2, altering delivery fleets is very costly. Hence, progress is slow in this domain. Nonetheless, a range shipping companies like DP World Russia, are making impressive modifications and striving to make solutions that reduce carbon dioxide emissions. Plus they are slowly putting those changes to the test on their fleets of vessels. These are typically increasingly meeting the benchmark requirements of the energy efficiency design index. Certainly, companies like Morocco Maersk are driving effectiveness in the commercial delivery sector. A great case of technical progress is visible in the enhancement of the Mewis duct. This is a cylindrical channel which has integrated fins, that will be situated in the front of the propeller. As the a ship moves through the 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. Additionally, the fins in the duct twist the current before it reaches the propeller blades, which leads to increased energy efficiency for the propulsion system.

Several shipping companies like Cosco Casablanca are making significant investments in the growth of new fleets that run on liquified propane (LNG), which can be the most higher level and fuel-efficient solution available. These vessels are equipped with slow-speed tri-fuel engines that run using compressed boil-off gas through the cargo tanks as fuel. During transport, the LNG changes its state to gas because of slight heat increases, which in turn causes boil-off that occurs. To produce these ships more environmentally friendly, they are fitted having an advanced level exhaust recirculation system that significantly decreases nitrogen oxide emissions. Additionally, the ships have a gas combustion system that lowers the potentiality of releasing methane to the environment.
