Résumé

The International Maritime Organization (IMO) released its fourth Greenhouse Gas Study, prepared by an international consortium comprising ten consultancies, research institutes and universities from four continents and led by CE Delft (the Netherlands).
The main findings indicate that greenhouse gas emissions of shipping increased by 9.6%, from 977 million tonnes (Mt) in 2012 to 1,076 Mt in 2018. Meanwhile, the carbon intensity of shipping operations improved by about 11%, but these efficiency gains were outstripped by growth in activity.
By 2050, emissions are projected to have increased by up to 50% relative to 2018, despite further efficiency gains, as there is expected to be continued growth of transport demand. While the impacts of the Covid-19 pandemic will probably cause a decline in emissions in 2020, these are not expected to significantly affect projections for the coming decades.
