Publishers

The publishers behind the data.

Six publishers today, from general-purpose databases to specialist domains.

How licensing works

Pay for the 11 you used, not the 11,000 you didn't.

Each publisher prices its data in credits (1 credit = $0.95), separately for impact results (LCIA), the full inventory (LCI) and individual properties. See credit prices per publisher

  1. Search for free

    Browse and compare data from every publisher.

  2. License it once, reuse it all year

    A license lasts a year and can be reused across unlimited models.

  3. Works across Circa

    Licensed data works in Gesserit, in Alia and through the API.

Compare

Compare before you license.

Search once and see the same product from every publisher or version that carries it. High-density polyethylene, for example, comes back from four ecoinvent releases, from Carbon Minds in 191 regions and from the US Federal LCA Commons. Each result shows its geography, system model, the impact methods it comes with and its price, before you spend a credit.

Illustrative layout: metadata and methods only, never impact values.

Geography

Regional precision, one vocabulary.

Every dataset maps to one shared list of regions, from countries and sub-national grids to aggregates, so a geography means the same thing whichever publisher it comes from. The Library uses more than 420 of them today.

Questions

About the data

What exactly is a datapoint?
Within a single Process (aka “activity” or “dataset”) you can license the impact results for one method, or the life cycle inventory.
For a Process exchange, the properties (e.g. price, mass) used in allocation are licensed separately.
Can I use different ecoinvent versions?
Yes. 3.9.1, 3.10 and 3.12 are available side by side. New versions are provided for free if they are released within your license period.
Do I need my own ecoinvent license?
No. Circa is a partner to ecoinvent, and ecoinvent datasets are available in the Circa Library, priced per datapoint in credits. If your organization already holds an ecoinvent license, talk to us about migrating it.
Is a license a subscription?
No. Credits are spent per datapoint, and each license lasts a year for each user. There is no monthly or per-use fee for data.
Why do datapoints cost different amounts?
Publishers set their own prices. Impact results, full inventories and properties are priced separately, and you see the price before you license.
