Details on the EXIOBASE Emission Factor Database

An overview of the Exiobase Emissions Factor Source

Summary

EXIOBASE is a global, detailed Multi-Regional Environmentally Extended Supply-Use Table (MR-SUT) and Input-Output Table (MR-IOT). It was developed by harmonising and detailing supply-use tables for a large number of countries, estimating emissions and resource extractions by industry. It was developed by a consortium of several research institutes in projects financed by the European research framework programs.

The EXIOBASE dataset is comprised of spend based emissions factors with global coverage across 44 countries, 5 Rest of World regions and includes 200 defined product catergories. EXIOBASE is generally considered one of the most widely used emission factor datasets globally for carbon accounting purposes.

The website for Exiobase can be found here.

Full Source Name	EXIOBASE
Sumday Concise Name	EXIOBASE
Description	Exiobase contains spend-based emissions factors, generally used in the Scope 3 portion of GHG Inventories. The dataset has global coverage with country-specific data for 44 major economies and less granular data covering the rest of the world.
Source Type	Academic
Most Recent Release Year	2021
Earliest Release Year	2019
Next Expected Release Date	Unknown
Sumday Take	Exiobase provides a solid dataset with global coverage. Where the inventory has been prepared in a country that does not have a government-endorsed spend-based emissions factor set, Exiobase provides a good alternative. EXIOBASE3 (the most recent dataset) has a base year of 2018, so an inflation adjustment should be considered for more recent GHG inventories. Exiobase emissions factors are expressed in terms of kg CO2e/ EUR. As a result, organisations may need to adjust the source data to reflect the local expenditure currency. In addition, disaggregated reporting based on specific greenhouse gases is not available from this source, this may also be a consideration for some organisations.
