Professional LCA, priced accessibly.
Model for free in the browser, pay only for the data you use. Collaborate with colleagues and clients. Built for consultants with many clients and in-house teams with a product range to cover.
From the first dataset to a signed-off result.
Find the data
Search every dataset in the Library, compare releases and regions, and see the price before you pay.
Build the model
Work in Gesserit, or start from a BoM file or spec diagram and let Alia match and scale the best datasets.
Report and share
Report results by phase or module, share the model with colleagues and clients, or send to verifiers.
Free to model. Paid by the datapoint.
No subscription
Modeling is free. Data is paid for per datapoint, only when it's used.
Clear costs per client
You pay for data, not seats, so each client's data cost is clear.
Leading databases, all in one place
ecoinvent, Carbon Minds, AGRIBALYSE, the Federal LCA Commons and more.
Unlimited seats
Bring in colleagues and clients at no extra cost. Only pay to license data for users with read/write access.
AI for the repetitive part
Alia structures BoMs, BIM files and spec diagrams and matches components. The practitioner makes the calls.
Built by practitioners
Designed in collaboration with dozens of LCA experts, the people behind Circa have done LCAs by hand, and know which parts shouldn't be.
Start for free. Pay as you grow.
With traditional annual software and database licenses, you pay the full year's cost before completing a single LCA. With Circa, modeling is free and you pay for the data each study uses, so you start at zero and your costs correspond to your work. Set the numbers to match your year.
