Every platform here supports ISO-aligned life cycle assessment and established inventory databases. The notes below are what sets each one apart, not an exhaustive feature list.
CarbonGraph
A modern web-based platform for life cycle assessments, Environmental Product Declarations, and product carbon footprints, with AI assistance built into the workflow.
Best for: Teams that want to produce web-based life cycle assessments and EPDs without a heavyweight desktop toolchain.
- +Browser-based, so there is no desktop install or per-seat client to manage
- +Covers life cycle assessment, EPD generation, and product carbon footprinting in one model
- +AI assistance aimed at reducing manual data entry

That is usAn AI-powered, web-based LCA platform covering the full product lifecycle, from Bill of Materials import through audit-ready EPD and ISO-aligned reporting.
Best for: Manufacturers, sustainability consultants, and ESG or compliance teams that need to get from a Bill of Materials to a defensible report quickly, and to keep the underlying data auditable.
- +AI-assisted Bill of Materials import and material matching, which removes most of the manual mapping work
- +Calculates on the ecoinvent and USLCI inventories, with the EF 3.1, TRACI 2.2, and PEF impact assessment methods
- +Pedigree-matrix data quality scoring, so every figure carries a traceable reliability signal
- +Aligned with ISO 14040, ISO 14044, and ISO 14067, with EPD and PCR workflows built in
- +Collaborative and browser-based, so teams and reviewers work from the same live dataset
Ecochain
A web-based LCA platform for manufacturers, covering product footprints across a portfolio and at facility scope.
Best for: Manufacturers who want accessible footprinting across a product portfolio without building an in-house LCA practice.
- +Covers product footprints across a portfolio and at facility scope
- +Web-based and aimed at non-specialist users
- +Built around manufacturing workflows

An enterprise platform that combines product environmental assessment with cost and supply-chain data in a single model.
Best for: Large enterprises that want sustainability analysis connected to supply-chain, procurement, and PLM decisions rather than run alongside them.
- +Links environmental impact to cost and supply-chain data
- +Built for enterprise-scale product portfolios
- +Designed to integrate with existing PLM and procurement systems
