What is it

Pymrio is an open source tool for analysing global environmentally extended multi-regional input-output tables (EE MRIOs). Pymrio aims to provide a high-level abstraction layer for global EE MRIO databases in order to simplify common EE MRIO data tasks. Pymrio includes automatic download functions and parsers for available EE MRIO databases like EXIOBASE, WIOD and EORA26_. It automatically checks parsed EE MRIOs for missing data necessary for calculating standard EE MRIO accounts (such as footprint, territorial, impacts embodied in trade) and calculates all missing tables. Various data report and visualization methods help to explore the dataset by comparing the different accounts across countries.

Further functions include:

Where to get it

The full source code is available on Github at: https://github.com/IndEcol/pymrio

Pymrio is registered at PyPI and on the Anaconda Cloud. Install it by:

.. code:: bash

pip install pymrio --upgrade

or when using conda install it by

.. code:: bash

conda install -c conda-forge pymrio

or update to the latest version by

.. code:: bash

conda update -c conda-forge pymrio

The source-code of Pymrio available at the GitHub repo: https://github.com/IndEcol/pymrio

The master branch in that repo is supposed to be ready for use and might be ahead of the official releases. To install directly from the master branch use:

.. code:: bash

pip install git+https://github.com/IndEcol/pymrio@master

Quickstart

A small test mrio is included in the package.

To use it call

.. code:: python

import pymrio
test_mrio = pymrio.load_test()

The test mrio consists of six regions and eight sectors:

.. code:: python

print(test_mrio.get_sectors())
print(test_mrio.get_regions())

The test mrio includes tables flow tables and some satellite accounts. To show these:

.. code:: python

test_mrio.Z
test_mrio.emissions.F

However, some tables necessary for calculating footprints (like test_mrio.A or test_mrio.emissions.S) are missing. pymrio automatically identifies which tables are missing and calculates them:

.. code:: python

test_mrio.calc_all()

Now, all accounts are calculated, including footprints and emissions embodied in trade:

.. code:: python

test_mrio.A
test_mrio.emissions.D_cba
test_mrio.emissions.D_exp

To visualize the accounts:

.. code:: python

import matplotlib as plt
test_mrio.emissions.plot_account('emission_type1')
plt.show()

Everything can be saved with

.. code:: python

test_mrio.save_all('some/folder')

See the documentation , tutorials and Stadler 2021_ for further examples.

Tutorials

The documentation includes information about how to use pymrio for automatic downloading and parsing of the EE MRIOs EXIOBASE, WIOD, OECD and EORA26 as well as tutorials for the handling, aggregating and analysis of these databases.
