About Circa

LCA data, on your terms.

Life cycle assessment helps people reduce impacts, compare options and design better products, and all of it depends on good data. We started Circa to change how that data reaches people. In the Circa Library you find and license exactly what you need, publishers can share their own data, and a modern modeling suite puts it to work.

Our story

One small choice, early on.

Early on, we made a decision that has shaped everything since: you pay only for the data you use, one datapoint at a time, and modeling stays free. It opened up LCA data to people a full database license would have priced out.

The same idea runs through the rest of Circa. Practitioners get better options for licensing data. Publishers get a way to reach those people and earn each time their data is licensed. And the whole field gets software built for how people work today.

What we believe

Three things we won't compromise on.

Rigor first

LCA should be precise and approachable at the same time.

AI you can check

Automation earns trust by being checkable, never by being magic. Every match shows its confidence, and you approve each step.

Fair, usage-based pricing

You pay for what you use. Modeling stays free.
