Emissions from ships
• To Air– Exhaust gas from ship machinery– Freon and Halon leakage from cooling equipment– VOC from the loading and discharging of crude oil and oil products
• To Sea– Sewage– Oil spills from engine room– Ballast water– Antifouling and paint– Washing of cargo compartments

The Impact of ship emissions is large in Europe due to the density of ship traffic
• Source: Dalsøren et al. 200910
High shipping traffic density in combination with wind and weather pattern high levels of sulphur and nitrate deposits in Western Europe

Options for reducing maritime air emisions• Reducing global transport volumes and tonnages• Reducing fuel consumption per freight unit transported • Replacing fossil fuel with renewable energy wind or solar, or
batteries with electricity from renewable sources. • Diesel engine modification• After treatment of the exhaust gas• Exchange the diesel engine with other engine technologies • Replacing diesel or heavy fuel oil with cleaner fuels in the
diesel engine• Alternative fuels and engine concepts

An approach to reducing the NOx emissions from shipping in Scandinavia
• The current NOx emissions from shipping in the region• Existing incentives to reduce NOx • Typical Seagoing vessels in the region• Assessment of the Abatement option • Conclusions

Typical vessel types in the Scandinavian & Baltic trades
• RoRo
• General Cargo / Container vessel
• Dry Bulker / tankers
• RoPax - Ferry

What are the annual fuel consumption and emissions of these vessels
• The annual fuel consumption is a function of the operational pattern.
• The table shows average annual fuel consumption for these vessel types and sizes. (Not exact match)
• I have calculated the NOx emissions based on engines satisfying Tier 2 requirements – the cargo vessels have slow speed engines, the RoPax medium speed engines
• The SO2 emissions are calculated based on fuel consumption and standard HFO
