HESTIA data are published in periodic versioned releases. Each release contains a fixed snapshot of all public data, recalculated using the current version of the HESTIA models and aggregated into national and global averages.
Each release includes:
Releases are identified by a version number (e.g., v1.0, v1.1). The version number and release date are displayed in the Data Explorer.
The current public release is available to all users through the Data Explorer, API, and download functionality.
Priority access to the latest version and a preview of the forthcoming release is available to contributors. See Priority Data Access for details on how to qualify.
Between releases, new data may be added to the platform and models may be updated. These changes are incorporated into the next release. Release notes document any changes to the model engine, including new models, updated emission factors, corrections to existing calculations, and changes to the geospatial datasets used for gap-filling. The public release remains fixed until a new version is published, ensuring reproducibility for users who cite a specific version in their research.
