The compliance options available to the global sulfur threshold are impacting greenhouse gas (GHG) and nitrous oxide (NOx) emissions from ships. The next regulation on GHG emissions, in addition to the ship’s energy efficiency design index (EEDI) requirements, was agreed upon by IMO on its GHG emission reduction strategy in 2018. As a result, the compliance options presented in this review can highlight the role and influence of integrated fuel-to-emissions technology solutions on compliance with reduced GHG emissions regulations. Efforts to convert alternative fuels for marine engines for safe and reliable use of potential new fuels such as methanol, LNG and ammonia have been presented in this work. Furthermore, the latest technological solutions for the control of combustion products were also discussed to highlight their contributions in reducing harmful and GHG emissions from internal combustion engines. In order to comply with IMO’s GHG emission reduction targets, maritime states are implementing a radical change in ship design and power generation to meet their emission reduction requirements with the challenge ahead to be solved is investment and infrastructure for production, storage and distribution of fuels to replace traditional fuels. This is a huge investment, a driving force to create a transport ecosystem to reduce carbon emissions in the future.
