According to the International Maritime Organization (IMO), the shipping industry's governing body, the sector is responsible for 2.2% of global emissions.
Without any intervention and if the current trajectory continues, shipping emissions are expected to grow by 50-250% by 2050.
Carbon dioxide (CO2) is the largest source of greenhouse gas emissions in shipping, but as a means of transportation shipping is the most CO2 efficient, as it releases the least CO2 per tonne travelled in comparison to air, road and rail.
Because of this, it remains the preferred method of transportation, carrying more than 80% of the world's goods.
As a large emitter in aggregate, there is therefore a key role for shipping to play in reducing the global carbon footprint and thereby achieving the sustainable development goal of climate action.Download PDF
