A new global shipping air pollution and GHG emission inventory using the bottom-up, well-to-wake MariTEAM model

摘要: Improving the robustness of maritime emission inventories is important to ensure we fully understand the point of embarkment for transformation pathways of the sector towards the 1.5 and 2C targets. A bottom-up assessment of emissions of greenhouse gases and air pollutants (BC, CO, NOx, SOx, VOC, CH4, and CO2) from the maritime sector will be presented, accounting for the emissions from fuel production and processing, resulting in a complete" well-to-wake" geospatial inventory. This high-resolution emission inventory is developed through the use of the state-of-the-art data-driven MariTEAM model, which combines ship technical specifications, AIS satellite ship location data, and historical weather data. The CO2 emissions for 2017 amounted to 943 million tonnes, which is~ 11% lower than the 4th International Maritime Organizations GHG greenhouse gas study for the same year.
