# Life-cycle assessment (LCA) software
Software and inventory databases that model a product's full life-cycle environmental impact — from raw-material extraction through end-of-life — combining a bill of materials with harmonized environmental input/output data to produce standardized results like global-warming potential, distinct from the consulting practice that interprets and reports those numbers.

## Overview and value chain
Markers: [EC: Life-cycle inventory databases and modeling software for standardized environmental impact calculation | OECD: Bioeconomy sustainability infrastructure | Regulator: none (modeling software/database, not a health/pharma regulator)]
Life-cycle assessment software models a product's full life-cycle environmental impact by combining a bill of materials and process flows with a life-cycle inventory database of harmonized environmental input/output data, producing standardized impact-category results. Sphera provides LCA software and data through its GaBi platform, offering both a managed LCA database and an "LCA for Experts" tier serving practitioners across the product-stewardship space. ecoinvent maintains the widely-used life-cycle inventory database that other LCA platforms — including SimaPro — draw on as their underlying data source. SimaPro's desktop LCA software delivers insights that drive positive change through detailed life-cycle modeling. GreenDelta's openLCA is an open-source LCA modeling platform, offering a freely available alternative to commercial LCA software suites. One Click LCA combines life-cycle assessment with carbon-footprint calculation in a single software platform, targeting the construction and product-carbon-accounting use cases growing fastest under regulatory disclosure pressure.
The key directions of LCA software are:
1. **Life-cycle inventory data provision:** maintaining and licensing the harmonized environmental input/output datasets that underlie any LCA calculation.
2. **Standardized impact modeling:** combining a bill of materials and process flows with inventory data to calculate standardized impact-category results (global-warming potential, water use, eutrophication).
3. **Open-source vs. commercial platform choice:** buyers choose between commercial suites (Sphera, SimaPro) with managed data and support, and open-source alternatives (openLCA) with lower licensing cost but more in-house modeling expertise required.
4. **Carbon-footprint-specific tooling:** newer entrants combine general LCA modeling with dedicated carbon-footprint calculation aimed at regulatory-disclosure use cases.

Cross-cutting technologies of the sector:
- **Life-cycle inventory databases:** curated, harmonized datasets of environmental input/output flows per unit process, the raw data an LCA software platform draws on.
- **LCA modeling software:** software that models a product's full life-cycle environmental impact by combining a bill of materials and process flows with a life-cycle inventory database.

## US
The United States hosts a leading commercial LCA software and data provider serving the broader product-stewardship market.
### Sphera's GaBi platform and managed LCA database
- **Sphera:** provides LCA software and data through its GaBi platform, offering both a managed LCA database and an "LCA for Experts" tier serving practitioners across product stewardship.

## CN
China is covered qualitatively rather than by a live-screened Chinese vendor: candidate Chinese LCA software firms searched during this screen returned no confirming 2026 source, so no Chinese company is tabled below.
### No confirmed named domestic vendor
- **Domestic gap:** no China-headquartered LCA software or inventory-database vendor confirmed by name in a live 2026 source was found during this screen.

## EU
The European Union hosts the category's deepest bench, spanning the underlying inventory database, commercial modeling software, an open-source alternative, and carbon-footprint-specific tooling.
### ecoinvent's underlying inventory database, SimaPro's desktop modeling, GreenDelta's open-source openLCA, One Click LCA's carbon-footprint focus
- **ecoinvent:** maintains the widely-used life-cycle inventory database that other LCA platforms, including SimaPro, draw on as their underlying data source.
- **SimaPro:** desktop LCA software delivering detailed life-cycle modeling insights for practitioners.
- **GreenDelta:** its openLCA is an open-source LCA modeling platform, a freely available alternative to commercial LCA suites.
- **One Click LCA:** combines life-cycle assessment with carbon-footprint calculation in a single platform, targeting construction and product-carbon-accounting use cases under growing regulatory disclosure pressure.

## Tech stack and innovations
The LCA software technology stack combines inventory-database infrastructure with a growing open-source and disclosure-driven layer:
1. **Harmonized inventory-database infrastructure:**
- ecoinvent's database underlies multiple commercial LCA platforms, functioning as shared data infrastructure for the entire category rather than a single-vendor product.
2. **Open-source modeling alternatives:**
- GreenDelta's openLCA offers a freely available modeling platform, lowering the entry barrier for organizations that can't justify a full commercial-suite license.
3. **Carbon-footprint-specific disclosure tooling:**
- One Click LCA's combined LCA-plus-carbon-footprint platform is purpose-built for the regulatory-disclosure use cases (construction, product carbon accounting) growing fastest under current sustainability-reporting requirements.

#### Stage 1: Bill of materials and process flows
The product's full bill of materials and manufacturing/logistics process flows are defined.
#### Stage 2: Inventory data matching
Each material and process flow is matched to harmonized life-cycle inventory data.
#### Stage 3: Impact-category calculation
Standardized impact-category results are calculated from the matched inventory data.
#### Stage 4: Standardized results generation
Standardized, comparable results — global-warming potential, water use, eutrophication — are generated across impact categories.
#### Stage 5: Results validation
The results are validated against known benchmarks and data-quality checks.
#### Stage 6: Interpretation and disclosure/reporting output
Validated results are interpreted and turned into the disclosure or reporting output the buyer needs.
