Circa (The LCA Studio) is a browser-based life cycle assessment platform designed for sustainability professionals, researchers, and organisations seeking faster, more accessible environmental modelling. It targets users who need to build product-level impact assessments without the overhead of traditional LCA software. By combining a large, pay-per-use data library with collaborative modelling tools, Circa shifts LCA from a specialised, time-intensive process toward a more flexible and iterative workflow. This is particularly relevant for teams working across product portfolios or early-stage design, where rapid modelling and access to diverse datasets can significantly reduce the effort required to generate credible environmental insights.

Core Features

Circa is built as a browser-native LCA environment that prioritises accessibility and scalability, allowing users to construct and iterate environmental models without local installations or complex setup. Its core features include:

  • Browser-Based LCA Modelling: Build complete life cycle models directly in a web interface without installing software.

  • Large LCA Data Library: Access millions of datasets from sources such as ecoinvent and Carbon Minds through an integrated marketplace.

  • Pay-Per-Use Data Access: Search datasets for free and only pay when specific data points are used in models.

  • Real-Time Collaboration: Teams can work simultaneously on models, enabling shared development and faster iteration.

  • AI-Assisted Modelling Tools: Features such as LCA copilots and automated data matching help reduce manual modelling effort.

  • Impact Reporting Outputs: Generate environmental impact results across multiple categories, including carbon footprint metrics.

Closing Insights

Circa is positioned as a newer generation of LCA software that focuses on lowering the barriers associated with traditional lifecycle modelling. Its design reflects a shift toward more iterative, collaborative workflows, supported by AI-assisted tools that automate data matching and model building. This is particularly relevant for organisations looking to scale LCA beyond specialist teams, as the platform enables quicker assessments across multiple products or design scenarios.

The platform supports a range of users—from individual practitioners and researchers to companies conducting product-level carbon assessments—illustrating its flexibility across different carbon accounting needs. Its emphasis on shared data access and collaborative modelling also aligns with increasing demand for transparency and reproducibility in environmental analysis.

A notable aspect of Circa is its pricing structure. Users can build LCA models for free and only pay for the data they actually use, typically priced at $0.95 per datapoint from the platform’s library. AI-enabled features are offered through Circa Pro at $99 per month per seat. This model reduces upfront costs and may appeal to organisations seeking to experiment with LCA without committing to traditional licence-based software.
