EXIOBASE 3

EXIOBASE 3 provides a time series of environmentally extended multi-regional input‐output (EE MRIO) tables ranging from 1995 to a recent year for 44 countries (28 EU member plus 16 major economies) and five rest of the world regions. EXIOBASE 3 builds upon the previous versions of EXIOBASE by using rectangular supply‐use tables (SUT) in a 163 industry by 200 products classification as the main building blocks. The tables are provided in current, basic prices (Million EUR).

There is a discussion about different licence options, please reach out for information. For help in use of EXIOBASE data for spend-based emission factors, email exiobase-support@googlegroups.com 

EXIOBASE 3 is the culmination of work in the FP7 DESIRE project and builds upon earlier work on EXIOBASE 2 in the FP7 CREEA project and EXIOBASE 1 of the FP6 EXIOPOL project. These databases are available at the official EXIOBASE website.

A special issue of Journal of Industrial Ecology (Volume 22, Issue 3) describes the build process and some use cases of EXIOBASE 3. This includes the article by Stadler et. al 2018 describing the compilation of EXIOBASE 3. Further informations (data quality, updates, ...) can be found in the blog post describing a previous release at the Environmental Footprints webpage. Various concordance tables for the database are available here.

Previous EXIOBASE 3 Versions

Some previous versions (3.7, 3.8) are also available on Zenodo. The even earlier public releases of the data (EXIOBASE v3.3 and v3.4) are available upon request. We recommend, however, to use the latest version due to significant updates of the economic data as well as major differences in water and land use accounts.

End year

The original EXIOBASE 3 data series ends 2011. In addition, we also have estimates based on a range of auxiliary data, but mainly trade and macro-economic data which go up to 2022 when including IMF expectations. A lot of care must be taken in use of this data. It is only partially suitable for analyzing trends over time! New data incorporating a full update for all SUTs to 2020 is soon available on request, reach out to exiobase-support@googlegroups.com

The basic description of the process employed is in the relevant deliverable (link to pdf download)..

As of v3.8 (doi: 10.5281/zenodo.4277368), the end years of real data points used are: 2015 energy, 2019 all GHG (non fuel, non-CO2 are nowcasted from 2018), 2013 material, 2011 for most others, land, water. More details are available in the readme file.

The EXIOBASE country disaggregated dataset EXIOBASE3rx provides land updates to 2015.

Some work is going on to update the extensions, but other collaborative efforts are more than welcome.

Bulk Download

To allow the download of specific years we uploaded the data as zip archives per year and mrio type (industry by industry: ixi, and product by product: pxp). If you need all data, we recommend the excellent zenodo_get python utility for the download.

After installing the tool, you can download the latest version with:

zenodo_get 10.5281/zenodo.3583070

Previous versions are available by replacing the latest DOI with previous record numbers.

Alternatively, you can contact us at exiobase-support@googlegroups.com for alternative access options.

IOT download and Pymrio integration

If your are only interested in the IO tables, Pymrio (version >= 0.4.5) includes an automatic EXIOBASE 3 download function which works with the EXIOBASE upload on zenodo. The EXIOBASE 3 files can then be parsed and analysed directly.

Nomenclature

Archives:

• IOT_YYYY_ixi.zip - MRIO archive for Year YYYY in industry by industry format
• IOT_YYYY_ixi.zip - MRIO archive for Year YYYY in product by product format
• MRSUT_YYYY.zip - Multi-regional Supply-Use table for year YYYY
• SUT.zip - Domestic Supply Use for each country and year

Content of IOT*.zip:

(the archive can be read directly by pymrio without unpacking).

The economic core is stored in the root of the archive, containing among

others:

• Z.txt - flow/transactions matrix
• A.txt - matrix/inter-industry coefficients, (direct requirements matrix)
• Y.txt - final demand
• x.txt - gross/total output
• unit.txt - Units of the flow data

We provide two set of extension data (stored in the sub-folders with the same name):

• satellite - uncharacterized stressors data - e.g. CO2 emissions, land use per category, etc.
• impacts - characterized stressors (=> impacts) - e.g. total GWP100, total land use, etc

The total list of stressors and impacts are in the index of all files, most conveniently in the 'unit.txt'.

Both extension subfolder contain: 

• F.txt - Factors of productions/stressors/impacts
• F_Y.txt - Stressors/impacts of the final demand,
• S.txt - Direct stressor/impact coefficients
• S_Y.txt - Stressor/impact coefficients of the final demand
• M.txt - MRIO extension multipliers (total requirement factors of consumption)
• D_cba.txt - Consumption based accounts per sector
• D_pba.txt - Production based accounts per sector
• D_cba_reg.txt - Consumption based accounts per region
• D_pba_reg.txt - Production based accounts per region
• D_imp_reg.txt - Import accounts per region
• D_exp_reg.txt - Export accounts per region
• unit.txt - Absolute units of the stressor and impacts

The unit of the coefficient data M and S are given be the unit of the satellite

account per unit of the economic core (e.g. kg CO2eq/Million Euro)
