Practical case for Croatia

The Croatian partner, Energy Institute Hrvoje Pozar (EIHP), in cooperation with subcontractor (EKONERG), has prepared 172 country-specific emission factors. The number of Croatian emission factors per category is shown in the table below.



The main reference document used to develop the Croatian carbon footprint database wass the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (2006 IPCC Guidelines), which defines how to calculate GHG EFs. The Croatian National Inventory Report 2017, Greenhouse Gas Inventory 1990 - 2015 (Croatian NIR 2017) contains data and information on EFs for the following sectors:

  • Energy,
  • Industrial processes and product use,
  • Agriculture,
  • Land Use, Land Use Change and Forestry (LULUCF)
  • and Waste.

The NIR contains data from the relevant National DBs, such as Energy Balances, Statistical Yearbooks, theEnvironmental Pollution Register, and the Waste Management Information System as well as national scientific research.

Information about EFs has been also collected from other existing sources that are consistent with the Clim'Foot approach. Data from European/International databases was taken into consideration for this purpose, however this data was adapted to reflect national circumstances. The following databases were analysed:

  • EFDB - Emission Factor Database (IPCC – International),
  • Base Carbone® (ADEME – France),
  • ELCD - European Life Cycle Database (JRC – EU)
  • and Bilan Carbone® tool - version 7.4 (2015).

A technical description focusing on each sector includes the relevant information on processes and national circumstances which are important for understanding how each process contributes to GHG emissions.  The calculation methods and metadata are listed in EF Database Croatian Report pdf file.

For example, in Croatia, heat is produced by different heating systems and some city districts have autonomous heating systems. The specific circumstances of each city were analysed to calculate the associated CO2e emission factors. Additionally, solar thermal collectors and geothermal heating systems were analysed and the associated emission factors were determined.


Creating the Croatian carbon footprint database has allowed them to identify product and process benchmarks in relation to sector-specific standards and provided data on several economic sectors.

Calculation methods and metadata are described in the EF Database Croatian Report pdf file.
