EXIOBASE

EXIOBASE: a global Multi-Regional Environmentally Extended Supply-Use Table (MR-SUT) and Input-Output Table (MR-IOT) with a focus on environmental sustainability analysis.

Global: EU and main trading partners (90 % of global GDP) + 5 RoW regions
Industry (163 industries) and product classification (200 products)
Over 1000 satellite accounts (“inflated” due to detail in water use and domestic extraction)
Consistent time series 1995-2016/2022 (now-casted)

The three main EXIOBASE versions

The main exiobase versions (Stadler et al 2018)

Development of EXIOBASE 2 mostly stopped, EXIOBASE 3 is the main version now.

Sector detail and time series

In principle, EXIOBASE 3 follows NACE1.1 and CPA2002
Some changes in energy, agriculture, waste
Tried to have the sector numbers in EXIOBASE consistent with these classifications
- letters indicating deviations (e.g. ‘w’ for waste products)
Aim to capture environmental relevant economic activities …
- … but increasingly used as a LCA substitute

Sector detail and time series

EXIOBASE is not based on the greatest common classification …

EXIOBASE is not based on the greatest common classification …
but extends national classification with auxiliary data
Implications for the time series:
- Auxiliary data is mostly static
- Coefficient interpolations based on national statistics (native classification)

Implications for the time series:
- Auxiliary data is mostly static
- Coefficient interpolations based on national statistics (native classification)
- same disaggregation shares across years (before balancing)

Changelog

EXIOBASE 3.4 (2018): public outcome of fp7 DESIRE (Stadler et al 2018)
EXIOBASE 3.7 (2019): Bug fixes, satellite data updates
EXIOBASE 3.8 (2020):
- Macroeconomic data update to 2018
- Now casting until 2022
- satellite data updates
  - CO2: EDGAR (2019)
  - other GHG: PRIMAST (2017),scaling to PRIMAST for all years
- bug fixes
EXIOBASE 3.8.1 (2021-03):
- Macroeconomic data update to 2019
- bug fixes (negative values)
- switch Cross Entropy objective function
- inclusing of “impacts” in the public version
EXIOBASE 3.8.2
- bug fixes
  - ixi time series was off by one year
  - some PRIMAP scaling errors

Development - upcoming projects

Since the end of DESIRE only ad-hoc development - infrequent updates

This will change in the future:

BAMBOO Horizon project https://bamboo-horizon.eu/
- Mitigating the impacts of non-food trade on biodiversity
- Linking EXIOBASE to FABIO

RAINFOREST Horizon project (webpage upcoming)
- Mitigating the impacts of food trade on biodiversity
- Linking EXIOBASE to LC-IMPACT
- Implementing “transformative change”

HiTEA NRC project (https://hitea.iedl.no)
- Uncertainty analysis for MRIO
- Focus on the data/computational pipeline

Development - crosscutting

Data updates
Push the time coverage
Improved data pipeline (regular updates)
Potentially increasing country coverage
No change in the sectoral detail planned

Auxiliary

Modular extension system

Several groups have/currently developing novel satellite accounts for EXIOBASE
Hard to find, hard to use
New modular extension system
- Automatically generated extension template (based on Python cookiecutter)
- Open Source toolbox for handing the most common modification tasks
- Common repository (Zenodo community) for the extensions
- Pymrio will include functions to pull these from the public repo and add them to EXIOBASE
- Added benefit: licence becomes more flexible (FAO is NC!)

Pymrio

Python package for handling MRIO data

Development focus:

Uncertainty analysis (HPC/cloud computing)
Modular system to add extensions
Binary data formats
- Currently csv files with defined file/folder names
- Adding Apache Parquet format
- Sqlite or others? - open for suggestions

https://github.com/konstantinstadler/pymrio (move to https://github.com/IndEcol soon)

Environmental footprints webpage

https://environmentalfootprints.org/

Compare different MRIO based on a common classification
All MRIOs are welcome
More regular updates planned (automated data pipeline)

Summary

EXIOBASE continues
Several upcoming projects will contribute to the development
Aim to further increase IO Open Science
- Planned special session at the IIOA 2023: “Open Source IO software”
Discussion points:
- Common file format for IO data?
- Collection of Open Source IO software
  - https://github.com/IndEcol/Dashboard
  - Perhaps an awesome list of Open IO / IndEcol software?
    - “An awesome list is a list of awesome things curated by the community.”
