Shipping is a potential contributor to marine eutrophication

Thought experiment:A month’s worth of shipping emissions would increase the nitrogen level in the sea within 10 km of the shipping lane significantly. The increase is comparable to about 5-20% of winter nutrient concentrations.

conclusions
Conclusions
  • In the Balticregion, shipemissionsaccount for up to 50% of the Nox deposition
  • Balticshippingcreatesmore SOx emissionsthanNordiccountries (FI, SE, NO, DK) togetherfromland-basedsources
  • Muchpolicy-levelactivityboth in the Baltic and internationally
  • Should WMO liaisemorecloselywith IMO to promote the study of shippingemissions and theireffects?
