JUST2CE Supply Chain Explorer

The JUST2CE Supply Chain Explorer is a learning tool which aims to support users to explore supply chains, better understand their complexity on the global scale, and explore elements related to justice and circularity.

Users can select a sector and country of interest from the drop down menu to start the analysis. The tool utilises the latest international macroeconomic data to visually map the location of the major economic inputs to the chosen sector.

AboutUse the tool

1. Select an economic sector

2. Select a country

3. Analyse and explore global and sectoral inputs

Shaded Countries

These represent the location of supply chain inputs for the selected sector/country where data exists.

Legend & Colour Coding

Darker shading means this country contributes more inputs to the selected sector/country. The colour bar at the bottom of the map indicates correspondence with the percentage of total inputs.

Layer toggles

Layers may be toggled in the top right. These currently display the locations of a range of JUST2CE case studies.

Country Info Boxes

Clicking on a shaded country produces a pop-up which provides a breakdown of the sectors contributing to the selected supply chain and justice related information.

Supply Chain Contribution

'Global impact' indicates the total percentage of inputs the country provides to the selected industry/country. This is further broken down by indicating the top 5 contributing sectors.

A just transition

Justice indicators currently displayed relate to the Global Rights Index and identified Environmental Conflicts.

Legend & Colour coding

The map is colour-coded according to the percentage of total inputs each country contributes to the chosen sector/country. For example, a figure of 4.8% for Spain means that for the production of goods or services within the chosen sector x within the chosen country y, Spain contributes 4.8% of the primary inputs for this activity (e.g. as raw materials, services, etc).

Country Pop-up Box

Once the map has been generated, the user can click on each country to reveal a pop-up box and display further details about the supply chain, as well as justice related elements. As of v1 of the tool, this box contains the following:

Section 1: The total contribution of inputs to the selected sector/country as a percentage of total inputs.

Section 2: A break down of the top sectors within this country which contribute to the selected supply chain. Given as a percentage of total inputs to the selected sector/country.
Section 3: Justice related information for the selected country. A comprehensive update of this is expected for the launch of v2. Currently it displays the Global Rights Index, and a link to the Environmental Justice Atlas.

Case-study Layers

The layer toggle in the top-right corner displays CE case studies which the user can click on to explore further details of JUST2CE’s work here.

Multi-Regional Input-Output Data

The foundations of the JUST2CE Supply Chain Mapper are based on multi-regional input-output (MRIO) tables.

Input-Output analysis is a macroeconomic technique used to understand the interdependencies of economic flows at national, and international scales. It is built upon tabulated information concerning the flows of products from each sector, the producer, to each of the other sectors, including itself, which are considered as consumers. At a fundamental level, Input-Output tables show how the output from one sector may become an input to another sector.


The initial dataset used within the development phase of the tool is EXIOBASE 3. It is expected that future development will consider alternative datasets with wider country coverage.

EXIOBASE 3 provides MRIO tables for 163 sectors per each of 44 countries (28 in Europe, plus 16 ‘major economies’), and 5 rest of the world regions, with annual datasets ranging from 1995 to 2022. The default dataset selected to be used within the current iteration of the tool is that for 2022, providing users with the most up to date information available.

How have sectors been defined?

Sectors correspond to data formatting of the 163 industries within the EXIOBASE 1 database. These roughly correspond to NACE Rev. 1 and ISIC Rev. 3 categories (both of which are now obsolete), with the addition of impact specific industries such as Recycling, and Landfill activities.

Justice Related Indicators

Whilst an update is anticipated soon, the current version of the tool only contains two justice related indicators, disaggregated at the country level.

The first is the Global Rights Index, which has been compiled by the International Trade Union Confederation, and assesses labour and trade union rights at a country level. This is indicated on a scale from from 1 (the best score) to 5+ (the worst score).

The second links to the Environmental Justice Atlas  which provides an important compendium of collated documentation on environmental conflicts. Read more about environmental justice and its importance to a just transition to a circular economy within our directory.

The tool’s development has been outlined across the various deliverables of JUST2CE’s Work Package 4.

The tool has been developed by various JUST2CE partners across the project. The tool’s design was led by colleagues at The University of Sheffield, with the technical implementation performed by Energy@Work. Testing has been led by the South-East European Research Centre, and dissemination activities planned by Medwaves.

Any enquiries about the tool should be directed in the first instance to Ben Purvis at the University of Sheffield.
