We are excited to announce that Exiobase 3.9.6 is now fully integrated and ready to use in Earthster!
As one of the most comprehensive environmentally extended multi-regional input-output (EE MRIO) databases available, Exiobase is an essential tool for tracking the environmental impacts of global supply chains. By bringing version 3.9.6 directly into Earthster, we are ensuring that your Life Cycle Assessments (LCAs) are powered by the most up-to-date and refined macroeconomic and environmental data.
Here is a breakdown of what the 3.9.6 update brings to the table and how it impacts your modeling.
The Specifics: What Changed in Version 3.9.6?
Exiobase 3.9.6 (originally released by the Exiobase consortium in June 2025) serves as a stabilizing update to the 3.9 series.
- Employment Account Fixes: The primary change in 3.9.6 is a targeted bug fix within the employment accounts within Exiobase.
- Consistency: The core economic Input-Output (IO) tables, energy data, and emissions accounts remain identical to those in versions 3.9.4 and 3.9.5, meaning your broader environmental baselines remain stable while social/employment metrics gain improved accuracy.
The Bigger Picture: Cumulated Updates in the 3.9 Series
If you are upgrading your Earthster projects from older versions of Exiobase (like the 3.8 series), you will benefit from a massive leap in data quality. Version 3.9.6 rolls up all the major enhancements introduced throughout the 3.9 lifecycle, including:
- Up-to-Date Emission Profiles: Emissions have been fully updated to incorporate now-cast fuel combustion data up to 2021, alongside a full update of non-fuel combustion data based on PRIMAP.
- Methane Accuracy: Addressed and fixed specific issues regarding methane non-combustion tracking.
- Refined Extensions: Includes crucial bug fixes to material and land extensions (introduced in 3.9.5), giving you much higher confidence in land-use and resource-extraction modeling.
- SUT Balancing & Alignment: Major updates to the Supply-Use Table (SUT) balancing routine, with better alignment to official economic accounts (such as EUROSTAT Figaro tables).
- Data Deprecations: Please note that Unused Domestic Extraction values have been removed from the material data to streamline and improve the accuracy of resource accounts.
How to Access Exiobase 3.9.6 in Earthster
You don't need to manually download datasets, wrangle CSVs, or import anything. Exiobase 3.9.6 is already waiting for you in your Earthster workspace.
Simply log in, select the new Exiobase 3.9.6 database from the library dropdown when creating or editing a cycle, and start modeling your global supply chains with the latest data.
Building the Ultimate Hybrid LCA: How Our Databases Work Together
Exiobase 3.9.6 is incredibly powerful on its own, but its real magic shines when combined with the rest of Earthster’s data ecosystem. While multi-regional input-output (MRIO) databases like Exiobase and USEEIO are perfect for top-down macroeconomic modeling, filling data gaps, and calculating broad Scope 3 emissions using spend-based data, they complement highly granular datasets flawlessly. In Earthster, you can seamlessly integrate Exiobase's broad global supply chain data with the bottom-up, process-based precision of Ecoinvent, PEF, USLCI, or BAFU for specific materials and manufacturing steps. Add in our specialized datasets—like CERDI-seadistance for maritime shipping routes, CORRIM for wood products, or regional profiles like the Dutch CO2 emission factors—and you have everything you need to build incredibly accurate, hybrid LCAs.
