Avoiding a bunker fuel mentality Nevertheless, the greenhouse gas emissions produced by the sector are significant and, according to the World Bank, the sector has not kept pace with other forms of transport, when it comes to climate action. The World Bank estimates that a single large shipping vessel, produces as much sulphur as 50 million cars. At around 800 million tonnes per year, the industry as a whole is responsible for approximately 2.2 per cent of all global emissions. Speaking at a plenary panel, during the Forum, on the importance of drastically reducing maritime emissions, Ms. Durant said that the maritime industry is heavily reliant on a form of liquid fuel (so-called “bunker fuel”) that has a high carbon footprint. Global seaborne trade is expected to double over the next twenty years, which means that it is imperative to make sure ships are powered in a way that is much more sustainable.
