LCA modeling,
for free.
Build LCA models with your team in real time using the top background databases, no install required. No subscription or seat limit, modeling is free.
Circa's modeling environment, Gesserit.
Models anyone can read
Build models that you can follow at a glance and explain to anyone, with automatic layout and annotations.
Background data made simple
Search and add datasets from every major database without leaving the platform. No downloads, installs, or extension databases.
Built for teams
Work on the same model as your team at the same time, with unlimited seats. Teammates who only view a model don't pay for its data.
Methods, side by side
EF 3.1, ReCiPe 2016, CML-IA, TRACI 2.1, IPCC 2021 and EN 15804+A2 indicators, side by side in one environment.
Support for EPDs
Classify Processes into EN 15804 modules from A1 to D, and see all required impacts by phase.
Uncertainty analysis
A 10,000-run Monte Carlo completes in under 30 seconds. Enter uncertainty for flows as distributions or pedigree scores.
Coming soon · An AI assistant built into Gesserit, working alongside you in your model.
No subscription, unlimited seats.
Build and edit models and license the data you use. Build the model before licensing results, and buy only the datasets within the model so you never overpay for data. Reuse datasets infinitely within a license year.
