If the global shipping industry were a country, it would be the world’s sixth-highest CO2 emitter, ahead of Germany. As an international industry, shipping was not covered by the 2015 Paris climate change agreement that focused on individual nations’ responsibility for critical emissions. But as unprecedented heatwaves, forest fires and flooding raise global awareness of climate change, the shipping industry is starting to make up for lost time.
How significant is their response? And was Maersk’s recent announcement of investing over US$1.4bn in eight post-Panamax containerships that can run on methanol or bunker fuel just a drop in the proverbial ocean? Let’s take a closer look at how shipping is responding to the climate crisis.
FleetMon supports ETH researchers to find the answer.
Fighting climate change demands action in all sectors. International shipping faces the challenge of long lifetimes of vessels compared to other modes of transportation. Decisions on energy carriers and propulsion technologies that are made now have a long-lasting impact on the emissions of the sector.
A research group at the Institute of Energy Technology at ETH Zürich led by Prof. Dr. Konstantinos Boulouchos developed a fleet turnover model for the shipping sector to estimate its future CO2 emissions up to 2050. Thereby, the CO2 emissions of existing ships and those of new ships entering the fleet yield yearly emission figures. However, up until recently, a missing puzzle piece for such models has been how long existing ships will actually still be in service. Missing or prohibitively expensive data has prevented analyses on this topic.
