One of the policies that could be key is the adoption of more efficient and cleaner technologies on ships. According to the report of the International Commission for Shipping (2019), the implementation of more efficient engines, hybrid or electric propulsion systems, and the use of renewable energies such as hydrogen or ammonia, can significantly reduce carbon emissions in the maritime transport industry. Furthermore, the report points out that optimizing ship load and speed management can also contribute to greater energy efficiency and, therefore, a reduction in emissions.
Turbochargers play a key role in the pursuit of energy efficiency in the shipping industry. These devices, which harness the energy of exhaust gases to compress the engine’s intake air, increase power and combustion efficiency, thus reducing carbon emissions per unit of energy produced.
The optimization of propulsion systems for ships, the adoption of more advanced and efficient turbochargers can contribute significantly to the reduction of emissions in the maritime transport industry. Investing in more innovative turbocharging technologies is therefore essential to achieving carbon reduction targets in this important area of the global economy.
Another important strategy is the implementation of stricter environmental policies and regulations internationally. In the words of Smith and Milligan (2020), authors specialized in maritime transport economics, regulatory measures such as limits on emissions of sulfur oxides (SOx) and nitrogen oxides (NOx), as well as the application of carbon taxes or the inclusion of maritime transport in emissions trading systems can encourage shipping companies to invest in cleaner technologies and reduce their carbon emissions.
Finally, the optimization of routes and logistics operations can contribute to a lower carbon footprint in maritime transport. Planning shorter and more efficient routes, as well as improving port traffic management, can reduce waiting times, lower fuel consumption and, consequently, carbon emissions.
