Turku is Finland's oldest city located on the Baltic Sea. The document discusses potential solutions to reduce greenhouse gas emissions in Turku's transportation sector through an integrated light rail network and supportive policies. A study by the city of Turku and Siemens found that a light rail system could reduce carbon emissions by 11% by 2035 while increasing property values along the network by €480-850 million and public transportation ridership by 40%. The light rail network is presented as an opportunity for Turku to develop a sustainable transportation system and livable environment.

2. Turku is an old city, going 
back as far as the 13th
century.
Located between Sweden 
and Russia, Finland also
borders the Baltic Sea,
Gulf of Bothnia, and Gulf
of Finland. Finland's area,
at 337,030 square
kilometers (130,127 square
miles).

3. Turku, Finland’s oldest 
city and its former
capital, is dominated by
its winding Aura river,
the reason for its
existence as a port.

4. The population of Turku was 177 606 in the year 
2010, which makes it the fifth largest city in Finland
by population.
There were roughly 303 500 inhabitants living in the 
Turku sub-region in the year 2007, which makes it
the third largest urban area in Finland after the
Greater Helsinki area and Tampere sub-region.

5. Turku is the main city in its region as well as the
cultural and economic centre of Western Finland.
The city’s profile has changed significantly in recent
decades.
The city has expanded by building residential areas
around the old city.
The city was rebuilt according to a grid pattern of
rectangular blocks in which the relatively broad streets
should prevent raging fires.

6. The city’s most famous attraction near the mouth of 
the river is its well-preserved medieval castle, dating
back to the days when Sweden ruled Finland in the
13th century.

7. The present physical 
structure of the inner
city is strongly
determined by the great
city of 1827 that
destroyed the
predominantly wooden
buildings of the old city
almost completely.

8. Medieval Castle
The outer walls are 
painted white with stark,
black-framed windows,
while inside is an older
medieval part with rough
stone walls.
Behind the castle’s thick 
stone walls, interlocking
corridors and courtyards
offer hints of its glory
days in the mid-16th
century, when the castle
served as the sumptuous
court of the Duke of
Finland.

9. Turku City Library in 
Turku, Finland by
JKMM Architects
Located at the 
historical centre of the
city.
The new building is 
the latest summation to
a complex with the old
library.

10. European Oak are widely 
used in the interior
wall furnishing and
furniture.
Building structure was 
constructed
from concrete cast on site,
which was left exposed as
an significant part of
the interior design.
Glass was given a seminal 
role both in the outer
architecture and the
interior world.

11. The major sources of 
greenhouse gas
emissions in the city.

13. Green logistic
• Downsize vehicle fleets and infrastructure
in the city centre and upgrade vehicles to
zero emission technology
Traffic
management
• Encourage P&R, guide drivers to the best
parking places, charge for entry to
congested areas, and car and bike sharing.
Biogas
• The gas can be piped for use directly as a
burnable fuel or used to power an
electricity generator.
Building control
and management
• Enable energy efficiency in new buildings
and renovations

14. This 2 project very attractive but need substantial work 
and funding.
These longer term solutions would build on the immediate 
opportunities to create a sustainable transport and energy
infrastructure.
Light rail transport (1
2) Smart Grid : Brings together the electricity and
communications infrastructure to help match supply and
demand.

15. Geothermal/ground heat : Using heat stored in soil, rock 
or water systems, transferred to a water-based heating
system using a heat pump.
Heat machines and chillers : Capture heat that would 
otherwise be wasted, either from cooling equipment or
heat production in boilers or power plants, and use it to
warm water for district heating or other purposes.

16. Public lighting : Technical and operational options can 
cut energy use, including sodium-vapor lamps instead of
mercury, LED technology and improved control
systems.
Micro combined heat and power (CHP) :small-scale 
power generation producing electricity from heat at low
temperatures using a fluid such as silicon oil instead of
water.
Smart parking: using parking regulation to encourage 
lower emissions vehicles and co-modality.

18. A way to improve air quality
and diminish environmental
impact by reducing CO2 and
pollutant emissions via
traffic reduction and
optimization.
Light rail gives also an
opportunity to reshape,
harmonize and develop a
city
An opportunity for Turku to
take the path towards a
sustainable transportation
system and a wealthy and
livable environment.
The integrated light rail
solution is the result of both
the implementation of the
light rail and a set of
targeted policies aiming at
favouring green
transportation as well as
triggering city development.

19. Trunk bus network will be
implemented in
Turku urban region 2011 to 2014,
covering
suburban Turku and centres of
neighbouring
Trunk bus lines to villages are
municipalities
defined :
• Skånetrafiken Pendeln a good
example
Centres and periphery of the villages
.
• Fast and effective public transport
lines
serve the centres every day from
morning to night
• Public transport lines can be
extended
over
Centres of separate villages function the centre to the periphery
as
intermodal interchanges between
public
transport, walking and cycling

21. Edges of central area (e.g.
Varissuo-Littoinen)
• Cycling and public transport
should continue to the edge
and be competitive with car
• Local services reachable by
walking
Outside built-up areas
• It should be possible to
connect to public transport by
car or bicycle at the nearest
built-up areas.
Separate built-up areas (e.g Masku,
Nousiainen, Mynämä
• It should be possible to walk or
cycle all trips within the area all
year round
• There should be an attractive
cycling and public transport
connection to the centre.
From the central areas
• Important recreational sites,
workplaces and services should be
reachable by cycling or public
transport, possibly depending on the
season
To the central areas
• Transports into the central areas should
not congest the main nodes into the City of
Turku or in the regional road network
• It must be possible to connect to the
public transport at the edges of the
congested area

22. Mobility management means
promotion of:
• Walking and cycling
• Public transport
• Sustainable car use

24. It is the cooperation with the city of Turku and Siemens.
The study evaluated the effects a light rail network would
have on Turku from an ecological and economic point of
view.
An integrated light rail solution would reduce carbon
emission by 11 percent by 2035.
Properties value alongside the network would increase by
an estimated total of 480 to 850 million euro in
conservative scenario.

25. Increase in the use of public transport can reduce the gas 
emissions.
The integrated light rail solution would increase the 
number of public transport trips in Turku by 40 percent
before 2035.
A third of the residents of Turku will live along the 
planned light rail system in 2035.

26. It is estimated that CO2 emissions from vehicle traffic in
Turku will rise by 25 percent, 130,000 tons by 2035.
Approximately 88 percent of emissions come from cars
and 12 percent from buses.
The integrated light rail solution would reduce CO2
from vehicles by 11 percent by year 2035.
Corresponding to an emission level of 110,000 tons.

27. The integrated light rail solution would reduce NOx by an 
additional 12 percent to about 250 tons in 2035.
One light rail carriage is equivalent to 40 cars and two 
buses.

28. The study shows that property values will rise in areas 
that are within walking distance of the light rail system
The price increase is expected to occur in 800 meter 
buffer zone along the planned light rail lines.
The value estimated would rise about 480 to 850 million 
euros in 2035.
