The sector currently accounts for 25% of the world’s greenhouse gas emissions. Energy efficiency is one of the biggest ways to cut emissions. While there is a consensus on the need to gradually phase out fossil fuels, LNG is seen as a stepping stone, while in the longer term, making the right choice between hydrogen, ammonia and biofuels remains a key challenge. Another way to reduce emissions is intermodality, with the aim of reducing the proportion of goods moved by road, and increasing short distance transport by rail, river and sea. Finally, innovating for more efficient logistics is the third solution. The aim is to reduce overall energy use, while ensuring that emissions avoided at sea are not simply moved onshore, particularly as a result of increased congestion in port cities.
