''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.

Leijupoltto|100-300|Wood|PM2.5|(multisyklone+) electric|mg /MJ|1-15|VTT 2005
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.

Leijupoltto|5-20|Peat|PM2.5|(multisyklone+) electric|mg /MJ|5-25|VTT 2005
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. One heating power plant can have several kettles. Many 5-50 MW power plants have also less than 5 MW a kettle. <ref> http://www.ymparisto.fi/download.asp?contentid=3706 {{attack|# |Link broken.

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.

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

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

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).

  • Classes of climate emissions:
    CO2direct
    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]

Other data

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.

Dependencies

  • Plant/kettle type
  • Power output
  • Efficiency

Data that have another unit than mg/MJ should be changed.

e.g. t/TJ -> mg/MJ
