EXIOBASE 3 is the culmination of work in the FP7 DESIRE project and builds upon earlier work on EXIOBASE 2 in the FP7 CREEA project and EXIOBASE 1 of the FP6 EXIOPOL project. These databases are available at the official EXIOBASE website or upon request.
A special issue of Journal of Industrial Ecology (Volume 22, Issue 3) describes the build process and some use cases of EXIOBASE 3. This includes the article by Stadler et. al 2018 describing the compilation of EXIOBASE 3. Various concordance tables for the database are available here.
As of v3.7, the end year is: 2015 energy, 2016 all GHG (non fuel, non-CO2 are nowcasted from 2015, CO2 fuel combustion is based on data points (see below)), 2013 material, 2011 most others, land, water.
The country disaggregate dataset has land updates to 2015:
In terms of data quality for more recent years. Please be mindful of:
-2007 is the base year for the SUTs and the method of interpolation over time involves using data in different classifications and formats to understand structural change over time (i.e. intermediate and final demand flows by product and industry). Only output, trade and macroeconomic constraints (7 sectors) are direct inputs to final balancing in absolute terms. The database is under the NACE1 classification scheme.
-SUT and IOT data are only used to inform structural change
-Whilst the 2007 EXIOBASE2 table is the base, the National Account Main Aggregates is the main constraint. The main goal was temporal consistency, and not disaggregation of official tables in EXIO3. SUTs/IOTs do often not get updated going backwards, whilst National Account Main Aggregates data does. In general, National Account Main Aggregates are often 10-20% off the equivalent data points aggregated from the official SUTs/IOTs from 2007.
In terms of financing future work, we of course are reliant on funding. Parts of the dataset are being updated based on individual project requirements, and NTNU has provided some internal funding for co-ordination across these efforts. We are of course welcome to participate in projects that help fund these updates – either central updates or peripheral work that has benefits for both a single end-user, but also that can be rolled into future public data releases.
