Downloading Data

All public data on the HESTIA platform can be downloaded without creating an account.

Individual Downloads

Each data page (Cycle, aggregation, Site, or Source) includes a download option. Data can be downloaded in the following formats:

• CSV: tabular format suitable for spreadsheet software and data analysis tools.
• Excel: .xlsx format for use in Microsoft Excel and similar applications.
• JSON-LD: the native HESTIA data format, suitable for programmatic use and integration into automated workflows.

Data Layout

Downloads are available in two layouts:

• Expanded format: term names are placed in rows. Column headers use numbered indices, e.g., cycle.inputs.0.term.name, cycle.inputs.0.value, cycle.inputs.1.term.name, cycle.inputs.1.value. This format is more readable but produces wider files.
• Compacted format: term identifiers are placed in the column headers, e.g., cycle.inputs.ureaKgN.value. This produces a more compact structure that is easier to work with programmatically.

The HESTIA Utilities library provides a tool to pivot expanded CSV files into the compacted layout.

Bulk Downloads

Bulk downloads can be performed from the Data Explorer. Apply filters (e.g., by product, country, or environmental indicator) to select the data of interest, then use the download option to retrieve all matching records.

Bulk downloads are available in CSV, Excel, and JSON-LD formats.

API Access

All public data can also be accessed programmatically via the HESTIA API. The Data API provides access to all public data in compacted format without requiring authentication.
