Rationale

HSY emission factors

This section describes the use of HSY emission factors used for CO2 emission estimates. This should be merged with the other data, but it is first described as such.

These emission factors are derived from the Helsinki Region Environmental Services (HSY) climate data [3] on 27th Nov 2018. Emission factors were initially calculated for every entry in the data file (4180 rows in total). Then, emission sectors were compared along timeline for each city separately. We noticed that several sectors shared practically the same emission factors with few differences, which are not plausible as real differences (Table Sector classification). So, we took a mean of the values to represent all sectors in the same EFclass group.

Then, we compared results from different cities. There were minor changes that may be due to some real differences in data, and also a some changes that looked like artefact. However, there were two sectors, namely district heating and fuels that clearly differed between cities in a plausible way. Therefore, we used city-specific emission factors for these two sectors and those of Helsinki for all other sectors (because Helsinki seemed to have the least amount of artefact in the data).

Direct CO₂ emissions from the stack

CO2trade

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].

+=== HSY emission factors ===
-The table below contains the current situation for Kuopio and Basel. Kuopio uses 'District', and Basel uses 'Long-distance heating'.
+''This section describes the use of HSY emission factors used for CO2 emission estimates. This should be merged with the other data, but it is first described as such.
-<t2b name='Fuel use in different heating types' index='Heating,Burner,Fuel' obs='Fraction' desc='Description' unit='-'>
+These emission factors are derived from the Helsinki Region Environmental Services (HSY) climate data [https://www.hsy.fi/fi/asiantuntijalle/ilmastonmuutos/hillinta/seuranta/Sivut/Paastot.aspx] on 27th Nov 2018. Emission factors were initially calculated for every entry in the data file (4180 rows in total). Then, emission sectors were compared along timeline for each city separately. We noticed that several sectors shared practically the same emission factors with few differences, which are not plausible as real differences (Table ''Sector classification''). So, we took a mean of the values to represent all sectors in the same EFclass group.
-Wood|Domestic|Wood|1|
-Oil|Domestic|Light oil|1|
+Then, we compared results from different cities. There were minor changes that may be due to some real differences in data, and also a some changes that looked like artefact. However, there were two sectors, namely ''district heating'' and ''fuels'' that clearly differed between cities in a plausible way. Therefore, we used city-specific emission factors for these two sectors and those of Helsinki for all other sectors (because Helsinki seemed to have the least amount of artefact in the data).

-In Finland there are about 700 kettles that has 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 has also less than 5 MW kettle. <ref>http://www.ymparisto.fi/download.asp?contentid=3706

+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.
