An open access forum to multi-regional input-output (MRIO) data, focussing on environmental footprints. Results include total environmental pressure including environmental impacts; intensity of environmental pressure per unit economic output; multipliers of environmental pressure per unit economic final demand;  footprints of final demand. All results are reported at a common classification to facilitate comparison.

For full product detail, please see the original databases (EXIOBASE, WIOD, EORA, OECD, GTAP) or use the contact form.

Results are based on standard input-output calculations, and can be reproduced by accessing the source data of the MRIO databases. A python package to calculate the results is available on  github.

The environmental footprints explorer is primarily based on output from 5 multi-regional input-output models:


EXIOBASE is a global, detailed Multi-regional Environmentally Extended Supply and Use / Input Output (MR EE SUT/IOT) database.

It was developed by harmonizing and detailing SUT for a large number of countries, estimating emissions and resource extractions by industry, linking the country EE SUT via trade to an MR EE SUT, and producing an MR EE IOT from this.

The international input-output table that can be used for the analysis of the environmental impacts associated with the final consumption of product groups.


Production processes increasingly fragment across borders. This fundamentally alters the nature of international trade with deep consequences for the location of production.

The WIOD is the first public database that contains new information on these trends and provides the opportunity to analyse the consequences of fragmentation, for example for shifting patterns in demand for skills in labour markets, or for local emissions of air pollutants.

The WIOD provides time-series of world input-output tables for forty countries worldwide and a model for the rest-of-the-world, covering the period from 1995 to 2011.

These tables have been constructed in a clear conceptual framework on the basis of officially published input-output tables in conjunction with national accounts and international trade statistics.

In addition, the WIOD provides data on labour and capital inputs and pollution indicators at the industry level that can be used in conjunction enlarging the scope of possible applications.


The Eora multi-region IO database provides a time series of high resolution IO tables with matching environmental and social satellite accounts for 187 countries.

    The Eora MRIO features:
  • 187 individual countries represented by a total of 15,909 sectors, continuous coverage for the period 1990-2011 (satellite accounts to 2010)
  • 35 types of environmental indicators covering air pollution, energy use, greenhouse gas emissions, water use, Ecological Footprint, and Human Appropriation of Net Primary Productivity

(Note: some of these will be made available soon pending the completion of analysis papers in progress).

Full list, high-resolution heterogeneous classification, or 25-sector harmonized classification, raw data drawn from the UN’s System of National Accounts and COMTRADE databases, Eurostat, IDE/JETRO, and numerous national agencies, distinction between basic prices and purchasers’ prices through 5 mark-ups, and reliability statistics (estimates of standard deviation) for all results.


The OECD inter-country input-output (ICIO) table was first constructed for the calculation of Trade in Value Added (TiVA) indicators during a joint OECD-WTO project. TiVA indicators are designed to better inform policy makers by providing new insights into the commercial relations between nations. The 2015 edition of the ICIO database includes 61 economies covering OECD, EU28, G20, most East and South-east Asian economies and a selection of South American countries. The industry list has been expanded to cover 34 unique industrial sectors, including 16 manufacturing and 14 services sectors. The years covered are 1995, 2000, 2005 and 2008 to 2011, a time series from 1995 to 2011 will be available soon (during 2016). In addition to the TiVA indicators, extensions of the ICIO regarding CO2 emissions from fuel combustion (based on IEA CO2 data), energy used for electricity production (based on IEA energy balances) and trade in employment are available.


The Global Trade Analysis Project (GTAP) is a global network of researchers and policy makers conducting quantitative analysis of international policy issues. GTAP is coordinated by the Center for Global Trade Analysis in Purdue University's Department of Agricultural Economics. The centerpiece of the Global Trade Analysis Project is the GTAP Data Base, a fully documented, publicly available global data base which contains complete bilateral trade information, transport and protection linkages. The GTAP Data Base represents the world economy and is utilized by thousands worldwide as a key input into contemporary applied general equilibrium (AGE) analysis of global economic issues. The current release, the GTAP 9 Data Base, features 2004, 2007 and 2011 reference years as well as 140 regions for all 57 GTAP commodities. The GTAP 9 database is converted into a multi-regional input-output model for calculation of environmental footprints for this website. Full details are in the documentation. Environmental extensions include Energy Use, and various greenhouse gas emissions.
