Question
What are the emission factors for burning processes and how to estimate emissions based on them? The focus is on the situation in Finland.
Answer
An example code for downloading and using the variable.
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]

This is other important data that wasn't in the end used in the model's calculations. These include for example emission factors for wood heating, emission types for different kinds of plants, kettles and fuels, and energy and sulphur contents of different fuels.

Emission factors for greenhousegases
Heljo & Laineen selvityksessä on päädytty seuraaviin kasvihuonekaasupäästökertoimiin (kgCO2/MWh) laskettuna rakennuksen bruttotasolla (rakennukseen hankittu energia)[6] Table 10.
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].
