On the 4th of August, the International Maritime Organization released its fourth study on Greenhouse Gases.  The study was commissioned by the IMO and was carried out by an international consortium composed of ten consultancies, research institutes, and universities from four continents,  led by CE Delft.

According to the study, emissions of greenhouse gases due to maritime transport increased from 977 million tonnes in 2012 to 1.07 billion tonnes in 2018 (an increase of 9.6%). The carbon intensity of maritime transport improved by 11% in this period, but the growth in activity was greater than the efficiency gains.

In the coming decades, emissions are projected to increase 50% by 2050 compared to 2018, despite more efficiency gains, as the demand for transport is expected to continue growing. While the impact of the Covid-19 pandemic is likely to cause a decline in emissions in 2020, they are not expected to significantly affect projections for the coming decades.
