| Zusammenfassung |
| Air pollution from shipping emissions contributes to overall air quality problems and has
direct health effects on the population especially in coastal regions and harbor cities. In order
to reduce these emissions the International Maritime Organisation (IMO) has tightened the
regulations for air pollution from ships. Since January 1st 2015, the allowed amount of sulfur
in shipping fuel which is responsible for SO2 emissions, has dropped from 1% to 0,1% in the
Emission Control area (ECA) that combines the North Sea and Baltic Sea. This effectively
excludes the use of heavy fuel oils by ships in this area. However, until now there is no
regular monitoring system available to verify that ships are complying with these new
regulations.
The project MeSMarT (Measurements of shipping emissions in the marine troposphere) has
been established as a cooperation between the University of Bremen and the German
Bundesamt für Seeschifffahrt und Hydrographie (Federal Maritime and Hydrographic
Agency) with the support of the Helmholtz-Zentrum Geesthacht to estimate the influence of
shipping emissions on the chemistry of the atmospheric boundary layer and to establish a
monitoring system for main shipping routes. Within the project, several hundred ships have
been monitored with focus on their sulfur fuel content, which is estimated by the ratio of SO2
and CO2, both measured with in-situ instruments from measurement stations near
the passing ships. It is shown how well ships have been complying to the sulfur
content regulation so far and which ships and how many are affected by the new
regulations. Three different measurement sites, ranging from measurements near
the Elbe River to open sea measurements from a research vessel are compared
to show if the distance to the coast has an effect on the fuel quality. First results
from very recent measurements of 2015 will be presented to show how the new
regulations are implemented and how this will result in reduced SO2 and thus better air
quality. |
