Exiobase
Exiobase, developed by 2.-0 LCA consultants, is a crucial global tool linking economic activities to environmental impacts. It offers detailed insights into global supply chains, resource use, and emissions, benefiting corporate, sectoral, national, and global footprint assessments.
The hybrid version of Exiobase is the most comprehensive global MR-IOT available, combining physical and monetary units for analysis across hundreds of industries and products worldwide. It harmonizes supply-use tables from different countries, creating a Multi-Regional Environmentally Extended Supply-Use Table (MR-SUT) and an Input-Output Table (MR-IOT).
Exiobase includes emission factors for fuel, electricity, waste, and purchase of goods and services, with a particular emphasis on food, as well as new and recycled materials. However, navigating the dataset can be challenging, especially in accessing data related to transportation emissions, which are often expressed in monetary values rather than in activity data. The methodology for calculating electricity emission factors is also unique, involving the use of marginal mixes.
Note
To access the Exiobase database, you need to register as a member and pay a minor fee.
We recommend reviewing the methodology used to create the factors in the database to avoid double accounting when combined with other datasets.

Note
The 2024 version (4.0) now uses wet-weight data instead of dry matter.
