Emission inventory for maritime shipping emissions in the North and Baltic Sea (2015)

TL;DR

This paper presents a detailed, high-resolution emission inventory for maritime shipping in the North and Baltic Seas in 2015, enabling assessments of environmental and health impacts, and mitigation strategies.

Contribution

It provides a comprehensive, geo-referenced emission inventory using a bottom-up approach with high temporal resolution for maritime shipping in 2015.

Findings

Detailed emission levels for multiple pollutants including CO2, NOx, SO2, PM2.5, and others.

High-resolution, geo-referenced data suitable for impact assessments.

Potential to evaluate mitigation strategies and health effects.

Abstract

A high temporal and spatial resolution emission inventory for the North Sea and Baltic Sea for the year 2015 was compiled using current emission factors and ship activity data. The inventory includes seagoing vessels over 100 GT registered with the International Maritime Organisation traversing in the North and Baltic Seas. A bottom-up approach was chosen for the compilation of the inventory, which provides emission levels of the air pollutants CO2, NOx, SO2, PM2.5, CO, BC, Ash, NMVOC and POA, as well as the speed-dependent fuel and energy consumption. Input data come from both main and auxiliary engines as well as well-to-tank and tank-to-propeller emission and energy and fuel consumption quantities. The geo-referenced data are provided in a temporal resolution of five minutes. The data can be used to assess, inter alia, the health effects of maritime emissions, external and social costs of maritime transport, emission mitigation effects of alternative fuel scenarios and shore-to-ship power supply.
