Slide 10: Life expectancy has increased across much of Western Europe and North America but decreased elsewhere due to PM2.5
EMISSIONS AND WÄRTSILÄ ENGINES Life expectancy has increased across much of Western Europe and North America but decreased elsewhere due to PM2.5 • Global population-weighted PM2.5 concentrations have increased by 37.5% over the period 1960 to 2009 – The increase is dominated by China and India due
Slide 11: Section 2: Greenhouse Gas (GHG) Emissions in General

Slide 12: There are many different sources of anthropogenic greenhouse gases
SOURCES AND SHARES There are many different sources of anthropogenic greenhouse gases Many different human activities contribute to global warming Energy production (25%) and transportation (14%) have a significant share of total global emissions (2010 data) Global shipping contributes nearly 3% of
Slide 13: Emission of greenhouse gases cause a warming and changing of climate
IMPACTS Emission of greenhouse gases cause a warming and changing of climate • Surface temperature is projected to rise over the 21st century. It is very likely that heat waves will occur more often and last longer, and that extreme precipitation events will become more intense and frequent in many
Slide 14: Not all greenhouse gases have an equal influence on climate change
GHG EMISSION FACTORS Not all greenhouse gases have an equal influence on climate change Emission factors enable different greenhouse gases These factors depend on the time horizon that to be expressed in a common unit (so-called ‘CO2- is considered; the 100-year GWP (GWP100) equivalent emissions’) w

Slide 20: Fuel production also causes GHG emissions
WTT, TTP AND WTW WELL-TO-TANK, EMISSIONS TANK-TO-PROPELLER AND WELL-TO-WAKE EMISSIONS Fuel production also causes GHG emissions • “Well-to-wake” (WTW) is a term used to specify the total amount of emissions generated as grams per ton kilometer or mile. I.e. the emissions produced to move one ton of
Slide 21: Well to tank emissions
WELL TO TANK EMISSIONS Fuel containing less carbon emits less Biofuels (example: biogas) can have negative GHG during the tank-to-wake phase well-to-tank emissions as they absorb CO2 from (example: HFO versus LNG) the atmosphere during “production” or growth 120 100 80 Total relative GHG emissions (
