The International Maritime Organization (IMO) has set mandatory emissions limits for ships, driving a need for a 65% reduction in greenhouse gas emissions by 2040. Leading the charge is the Getting to Zero Coalition, consisting of 200 companies working towards full decarbonisation by 2050 through the adoption of zero-emission fuels. Ammonia, biofuels, dual-fuel vessels, and wind-assisted propulsion are emerging as key solutions to reduce emissions in the shipping industry. While ammonia bunkering trials are progressing, safety concerns and high costs have limited ship orders. Major ports like Rotterdam and Singapore are gearing up for ammonia infrastructure, with Rotterdam recently completing a trial ammonia transfer between ships. Companies like Maersk and Nestle are investing in biofuels and dual-fuel vessels to meet emissions targets, with Maersk having 13 dual-fuel ships in operation and plans for 20 more by 2028. The industry is exploring various green fuel options, including green methanol and e-methanol, to achieve significant greenhouse gas emissions savings. Despite challenges, there is a collective effort to drive green shipping innovation and achieve a sustainable future for the maritime sector.
