Scope
Purpose
Heating is big part of used energy in northern countries and thus big part of cities emissions are from heating. This assessments purpose is to evaluate greenhouse gas emissions, which are caused from heating in Helsinki Metropolitan Area under 50 MW plants for heating and influence on health. Then, Based on these evaluations, purpose is determine the most effective heating solution for the area by environmentally and by costs.
Emission trading and structural changes, like migration to the area and expanding district heating, will be taken into account when determing the best solution for heating.
Boundaries
- Spatial: Helsinki Metropolitan Area (Helsinki, Espoo, Vantaa, Kauniainen).
- Emissions: CO2, PM2.5.
- Heating methods:
- District heating, All < 50 MW plants.
- Single-Family house heating methods.
- Fuels: All (H/L oil, Pellet, Chip, Gas, Coal).
- Other impacts: Costs
- directly from the activity itself of the greenhouse trade
- new district heating extension costs
- Population: The whole population in the Helsinki Metropolitan Area (capital region) is considered as the active population making societal and individual decisions and where the health impacts of the activities occur. However, climate change impact of the emitted greenhouse gases is considered globally.
- Decisions:
- International: base-case and possible/interesting variations to the EU emission trading system (taken as an outside boundary condition) D↷
- City-level decisions: D↷
- Extension of the district heating/cooling system to less-populated areas (Yes/No). This may take place in building small-scale (2-10 MW oil/wood chip power plants)
- Subsidies for improving energy efficiency in buildings (Yes/No)
- Area planning and land use (Dense vs. loose city structure for new buildings)
- One nuclear power plant is built in Finland, and the heat load is utilised in the district heating of the Helsinki Metropolitan Area.
- Choice of fuel for district heating
- Citizen-level decisions:
- Choice of the heating system in the own single-family house (Electricity/Oil/Wood chip) (see Bioher)
Scenarios
Base-case:
- Current district heating status in Helsinki Metropolitan Area
- emissions
- fuels used in plants
- city's need for heat
- costs
Future scenarios:
- Changes in district heating network:
- expansion?
- costs, especially what does emission trading affect on costs
- new plants

Definition
Deficion variables
- Decisions:
- International: Options of the international greenhouse gas trade mechanisms
- City-level decisions:
- Extension of the district heating/cooling system to less-populated areas (Yes/No). This may take place in building small-scale (2-10 MW oil/wood chip power plants)
- Subsidies for improving energy efficiency in buildings (Yes/No)
- Area planning and land use (Dense vs. loose city structure for new buildings)
- Citizen-level decisions:
- Choice of the heating system in the own single-family house (Electricity/Oil/Wood chip)(see Bioher)
Decision variables related to the international treaty:
What are the instruments used?
- CO2 trade
- Energy tax
- Other taxes
- Emission limits
- Bans of activity
Major questions
- Which countries participate in the GHG trade?
- Which sectors are covered?
- Which pollutants are covered?
- CO2
- N2O
- CH4
- CFC
- Land albedo
- PM2.5
- To whom are the quotas given/sold?
- What is the initial price of the quota?
- What is the level of ambition (i.e. the amount of quota that is distributed)?
- What sanctions are forced on those outside the treaty?
Indicator variables
Other variables
