In 2018, IMO adopted an initial IMO strategy on reduction of GHG emissions from ships, setting out a vision which confirms IMO’s commitment to reducing GHG emissions from international shipping and to phasing them out as soon as possible. Reduction of Greenhouse gases (GHG) and its effect to climate change is a challenge for governmental, intergovernmental bodies and above all maritime industry and its professionals.
The challenge of reduction of GHG Emissions is now mainly based on reduction in use of conventional marine fuels and explore further the Alternative Marine Fuels which could reduce emissions and achieve targets.
In 2011, the IMO introduced the first regime for mandatory reduction methods and mechanisms on ships. Similarly, as part of the overall effort to control air pollution, shipping emissions, specifically SOx (oxides of sulphur), NOx (oxides of nitrogen) and particulate matter, have increasingly become an area of focus.
The global merchant fleet consumes an estimated 330 million tonnes of fuel per year, therefore development of alternative fuels for shipping is increasing (DNV, 2014) primarily driven by an anticipated long term increase in costs of oil and especially, the need to reduce harmful emissions from ships, liked to ever tightening legislation. Current avenues for alternative fuel consist of: Liquefied Natural gas (LNG), Liquefied Petroleum Gas (LPG), methanol and ethanol, Di-Methyl Ether (DME), synthetic fuels, biodiesel, biogas, hydrogen, nuclear fuel and stored electricity.
The Marine Fuels and Emissions SIG encompasses issues within the two overarching themes of emissions from shipping, and alternative fuels for shipping. This SIG aims to understand shipping’s role in GHG emissions and air pollution, and the measures being discussed to address them including new regulations, new fuels and associated implementation issues. This SIG will look to identify and address the challenges that lie ahead working with regulatory bodies and industry partners to provide guidance. In bringing together a network of professionals to share experiences and review the knowledge and skills gap across the industry, targeted support can be given to those working in in the sector.

This is the first investigation in the IMarEST's Engine Room Perspectives which aiming to better understand the challenges faced by seafarers in the installation, commissioning, operation and maintenance of certain equipment types.
