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 countries and industries by trade. The international input-output table that can be used for the analysis of the environmental impacts associated with the final consumption of product groups. To facilitate the data comparability, environmental accounts are provided in a standardised classification. 


WIOD is the first public database that provides the  opportunity to analyse consequences of fragmentation, e.g. shifting patterns in demand for skills in labour markets, or local emissions. 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, 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.


Eora provides time series of high resolution IO tables with matching environmental and social satellite accounts for 187 countries. Full list, high-resolution heterogeneous classification, or 25-sector harmonised 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 database features 187 individual countries represented by a total of 15,909 sectors, continuous coverage for the period 1990-2011 (satellite accounts to 2010). In terms of environmental extensions, 35 types of environmental indicators are featured covering air pollution, energy use, greenhouse gas emissions, water use, Ecological Footprint, and Human Appropriation of Net Primary Productivity.


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. 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 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.


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 database 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 MRIO model for calculation of environmental footprints for this website. Environmental extensions include Energy Use, and various greenhouse gas emissions.
