Ships move most internationally traded goods between countries. Low-cost seaborne transport allows countries to import essential commodities \u2013 such as food, clothing, and pharmaceuticals \u2013 and export their own signature products competitively. To safeguard low transport costs, we have analyzed how more energy efficient shipping can support ships in switching to new energy sources in a cost-efficient way.<\/p>\n

In the recent past, public discourse around the maritime transport sector\u2019s energy transition has mainly focused on alternative fuels. A quick search through the industry\u2019s sectoral media outlets shows that most coverage dealt with green fuels like biofuels, hydrogen-based fuels, or liquefied natural gas \u2013 touted as alternatives to oil-based fuel like heavy graded fuel oils or distillates. Energy efficiency, however, only appeared in less than a third of energy transition reporting.<\/p>\n

Is the world overlooking the significant potential for lower emissions and lower costs in a sector that moves 70-80 percent of global trade every day?<\/p>\n

Putting Ship Energy Efficiency Back in Focus<\/b><\/p>\n

In our recent Keys to Energy-Efficient Shipping<\/a> report, we set out to answer this question by modelling how greater energy efficiency could shape maritime transport over the coming years. <\/b><\/p>\n

The results were striking: in 2030, up to about 40 percent of ship emissions can be cut by energy efficiency alone. This means that just maxing out energy efficiency will be more than enough to reach the targets of the International Maritime Organization of reducing emissions by 20-30 percent until 2030<\/a>. This is good news not only for those concerned about climate change, but also for vulnerable communities living close to ports, who are exposed to harmful air pollution from ship traffic.<\/p>\n

Importantly, more than half of these energy-efficiency measures come at a negative cost, meaning they pay for themselves. Cost savings from reducing energy consumption fully cover \u2013 and often exceed \u2013 the costs of installing wind-assisted propulsion (like rotor sails on bulk carriers) or reducing the speed of container ships.<\/p>\n

All of this makes energy efficiency the ideal complement to alternative fuels. Together, these efforts can drive shipping\u2019s energy transition, presenting a significant market opportunity for developing countries like South Africa, Colombia, and Morocco. Our estimates show that as much as $220 billion can be saved every year in the transition from fossil fuels to green fuels. As such, energy efficiency measures not only minimize the fuel bill of new or retrofit ships running on green methanol or green ammonia, but also benefit incumbent vessels still dependent on fuel oil through lower fuel consumption.<\/p>\n
