Greener shipping –
focus on emission to air
In Emission Control Areas (ECA) for new ships after 2016 have to meet limit of SOx
= 0,1% and NOx
reduction of 80% of today's limit
Expecting new special limits for Particular Matter (PM)

Summing up
The main challenge for the shipping industry is emissions to air; SOx, NOx, PM and GHG
Improvement of energy efficiency has a significant potential for reduction of GHG and at the same time reducing the harmful
emissions and it is good for the economy.
LNG is considered to be the main alternative fuel to fuel oils. LNG fuelled ships will meet all the known emission requirements without exhaust gas cleaning and has a considerable potential to a net reduction of GHG
Renewable fuels? Just a small portion from wind, solar and wave are considered realistic. Liquid methane from biomass could replace the fossil based LNG
