Example of the use of emission factors: CO₂ and fine particle emissions in Helsinki. Scenarios are based on Helsinki energy decision 2015.

An example code for downloading and using the variable.

Rationale

Inputs and calculations

**Variables needed for calculating emissions.**
Dependencies	Measure	Indices
fuelUse (from Energy balance or other relevant source)	Amount of fuel used per timepoint.	Required indices: Fuel. Typical indices: Plant
emissionsLocations (case-specific knowledge from e.g. Helsinki energy production)	Tells how where emissions occur and from how high a stack.	Required indices: - . Typical indices: Plant
emissionFactors (generic information, but may be cultural differences. E.g. Emission factors for burning processes ##	emissions per unit of energy produced (g / J or similar unit)	Required indices: Pollutant, Fuel. Typical indices: Burner.

CO₂ emissions as they are defined in the emission trade. Non-trade sectors have emission 0.

CO2eq

CO₂ emissions as equivalents (i.e. includes methane, N₂O and other climate emissions based on life cycle impacts.

In Finland there are about 700 kettles that have under 5MW fuel power. Same amount is between 5 to 50 MW kettles and over 50 MW kettles there are 200 in Finland. One heating power plant can have several kettles. Many 5-50 MW power plants have also less than 5 MW a kettle. ^[2]

Emission factors vary greatly depending on kettle or plant type, fuel type and fuel power. Type of emission and possible PM separator also affect to EF number.

Data been used in this page is from many different study and sources to get wide data base for EF caculations.

NB

BIO = biofuel, whose carbon dioxide emissions are not counted in the total emission amounts of Finland's greenhouse gases, nor are they taken into account in emissions trading.

1) CO₂ factor of mixed fuels is an estimate taking into account only the share of fossil carbon.

2) Gasified waste (Product gas) is reported in the fuel categories of the source materials of gasification.

Calorific values and emission coefficients describe the properties of fuel as fired, inclusive of moisture content (except for 313, where the measurement unit is tonnes of dry matter). Calorific value of natural gas has been specified in normal conditions (0 °C and 1.013 bar).

Emission factors are updated when necessary.

(* Revised values.

Emission factors for district heating is calculated in Motiva CO₂ emission calculation introductions^[8]. For district heating joint production emission factor is 220 kg CO₂/MWh. In this view other GHGs (CH₄ or N₂O) are not taken account as CO₂-ekv! Emission factors by fuel based on Motiva knowledge is in table 2.

Table 12. Emission factors of CO₂ by fuel^[9].

Fuels	kg CO₂/MWh
Heavy oil	279
Light oil	267
Gas	202
Fluid gas	227
Peat	382
Coal	341
Coke	389
Wood	0

CO2 EF for electricity can be classified in two categories: purchase electricity and own production. EF for purchase electricity is the same as own electricity vendor has informed or average Finnish electricity procurement CO2 EF (= 200 kg CO2/MWh). EF for own electricity production can be used EF from table 2 (fuel based EFs). If electricity is produced in combined electricity, heating production EFs are calculated with “benefit division method”. Method is explained in Motiva introduction^[10] (attachment 2).

Table 13. Average emission factors measured with differed gas analyzator (kk) and FTIR analyzator ^[11].

	Ordinary combustion	Distribution (%)	Bad combustion	Distribution (%)	Unit
Temperature of gas	253	1	159	17	Celsius
CO2 (kk)	7.3	5	11	8	%, dry
O2 (kk)	13.3	3	8.7	14	%, dry
H2O (FTIR)	6.5	4	7.7	-	%, wet
CO (kk)	2300	10	8100	29	mg/MJ
CO (FTIR)	2000	11	5700	-	mg/MJ
OGC (kk)	120	17	1700	46	mg C/MJ

CH4 (FTIR)	30	22	350	-	mg C/MJ
C6H6 (FTIR)	20	27	210	-	mg C/MJ

Table 14 and 15 are from Heljo et al 2005^[12]. Coefficient of CO₂-ekv/CO₂ as 1.02 is used in transformation CO₂ emission factors to CO₂-ekv. factors for electricity and district heating.
