Fourth IMO Greenhouse Gas Study: Shipping emissions are projected to increase by up to 50% until 2050, relative to 2018
The greenhouse gas emissions of shipping have increased from 977 million tonnes in 2012 to 1,076 million tonnes in 2018 (9.6% increase). The carbon intensity of shipping has improved by about 11% in this period, but the growth in activity was larger than the efficiency gains, CE Delft said in its release.
In the next decades emissions are projected to increase by up to 50% until 2050, relative to 2018, despite further efficiency gains, as transport demand is expected to continue to grow. While the impacts of the Covid-19 pandemic will probably cause a decline in emissions in 2020, they are not expected to significantly affect the projections for the coming decades.
These are the main findings from the Fourth IMO Greenhouse Gas Study which has been released today. The study has been prepared for the International Maritime Organization by an international consortium comprising ten consultancies, research institutes and universities from four continents. The consortium was led by CE Delft.
