LCA Data for Life Cycle Assessment: Unlocking Environmental Insights

In the pursuit of sustainability, Life Cycle Assessment (LCA) has become a powerful tool for evaluating the environmental impact of products, processes, and organizations. But a credible LCA depends on one thing above all: reliable data on energy, material, and emission flows. This is where LCA databases come in.

This guide explains what LCA databases are, how they differ from life cycle inventory (LCI) databases, and how to choose the right one for your goal and scope — from free, open databases such as ProBas, BAFU:2025, and USLCI to commercial options like ecoinvent and Carbon Minds.

Why Data Is the Foundation of Every LCA

Data is what turns a Life Cycle Assessment from a framework into a result. It is the basis for calculating environmental impacts and for spotting where a product or process can be improved. LCA software provides the structure for an assessment, but the quality, completeness, and representativeness of the underlying data ultimately determine how reliable and defensible the results are.

In practice, no organization can measure every input and output along a full life cycle. That is exactly why LCA databases exist: they supply trustworthy background data so practitioners can focus their effort where it matters most.

Primary vs. Secondary Data in LCA

LCA practitioners work with two types of data. Primary data is collected directly from the source — your own production processes or supplier inventories. Because it reflects the specific conditions of the system under study, it is usually the most accurate. Its drawback is effort: gathering primary data is time-consuming and costly, especially for processes that are geographically dispersed or outside your direct control.

Secondary data comes from LCA databases and represents average or generic processes. It is used to fill the gaps that primary data cannot practically cover, keeping a study complete without inflating cost and time. Most real-world assessments combine both: primary data for the processes you control, secondary data for everything upstream and downstream.

What Are LCA Databases? LCI vs. LCA Databases

An LCA database is a curated collection of LCI datasets describing the energy, material, and emission flows associated with a component, process, or product. These datasets let practitioners in industry and research fill the gaps in their own inventories in a cost-effective, efficient way, ensuring the completeness of a study.

Strictly speaking, there is a difference between the two terms often used interchangeably. An LCI database provides only the inventory data. An LCA database goes further and also includes Life Cycle Impact Assessment (LCIA) methods, which translate those flows into potential environmental impacts across a product's life cycle. In everyday language, "LCA database" is used for both. The databases below are the ones most relevant for professional LCA work — and the ones integrated into Umberto.

ecoinvent: A Global Leader in LCA Data

The ecoinvent database is one of the most widely recognized resources for LCA data. With more than 20,000 LCI datasets and global coverage, it is a comprehensive, regularly updated source for conducting LCAs across virtually any sector.

Its biggest strength is transparency. ecoinvent provides datasets as individual unit processes — not just aggregated results — which enables detailed analysis of product life cycles. It documents data sources and methodologies in depth, publishes annual reports on database changes, and supports different allocation approaches to match varying study goals and scopes. For customer-facing assessments and studies with high data-quality requirements, that traceability and flexibility make ecoinvent a preferred choice. ecoinvent is a commercial database that can be added to Umberto as an add-on.

Carbon Minds: Specialized Data for Chemicals and Plastics

Carbon Minds provides highly accurate, regionalized LCI data for chemicals and plastics. Its cm.chemicals database covers 95,000 datasets spanning a vast range of chemicals and plastics, making it a strong fit for companies in the process and materials industries.

It offers production and consumption mixes for bulk chemicals along with the major technology pathways in various data packages, and data-on-demand for the full range of chemicals and plastics. The database is aligned with the "Together for Sustainability" guideline for the Product Carbon Footprint (PCF), and its "Supplier Carbon Footprints" deliver region-, plant-, and supplier-specific emission data that help reduce Scope 3 emissions. Carbon Minds is a commercial database available as an Umberto add-on.

BAFU:2025: The Swiss Federal LCI Database

BAFU:2025 is a free, high-quality LCI database provided by the Swiss Federal Office for the Environment (FOEN/BAFU). The BAFU:2025 database contains around 11,000 life cycle inventories across 176 categories, covering sectors such as construction, mobility, energy, metals, chemicals, paper, agriculture, food, consumption, and waste management.

All datasets comply with the BAFU data-quality requirements (DQRv2:2023) and are ISO 14040-compatible, with most having undergone a critical review. Because it is published free of charge under the Swiss Open Government Data strategy, BAFU:2025 is a strong option for DACH- and EU-oriented industrial screening, material and process comparisons, PCF readiness, and portfolio prioritization — and it is included in Umberto by default.

ProBas: Background Data from the German Environment Agency

ProBas ("Prozessorientierte Basisdaten für Umweltmanagement-Instrumente") is a free database from the German Environment Agency (Umweltbundesamt, UBA). The ProBas database brings together more than 20,000 datasets on energy, materials and products, transport, and disposal, all searchable, filterable, and downloadable in standard export formats at no charge.

Because it consolidates numerous publicly available data sources, ProBas is well suited to German reference use cases, basic background data, education, and complementary checks alongside other databases. Like BAFU:2025 and USLCI, it is one of the open databases included in Umberto by default.

USLCI: The U.S. Life Cycle Inventory Database (NREL)

The U.S. Life Cycle Inventory (USLCI) Database, developed by the National Renewable Energy Laboratory (NREL) and its partners, is a free repository of life cycle inventory data for materials, products, and processes relevant to the United States. It provides individual gate-to-gate, cradle-to-gate, and cradle-to-grave data on environmental impacts across the full life cycle — from raw material extraction through production, use, and disposal. USLCI is a strong choice whenever North American background data is relevant, and it is included in Umberto by default.

How to Choose the Right LCA Database

There is no single "best" LCA database. The right choice depends on what you are assessing, how detailed your model needs to be, and how the results will be used. Before committing to a database, it pays to weigh a few core criteria against the goal and scope of your study.

Key Criteria for Selecting an LCA Database

Four criteria matter most when comparing databases:

• Data quality and transparency: How traceable and well-documented are the datasets? Are they available as individual unit processes or only as aggregated results, and have they undergone a critical review?

• Geographic representativeness: Does the database reflect the regions in your supply chain — the relevant energy mixes, technologies, and production conditions?

• Coverage of materials, processes, and sectors: Are the specific materials, components, and processes you need actually included, and in sufficient depth?

• Goal and scope of your LCA: Which environmental impacts do you want to assess, which LCIA method and indicators do you need, and how will the results be used — for internal screening, or for customer-facing and audit-near work?

Matching the Database to Your Goal and Scope

For LCA entry, screening, hotspot analysis, and internal PCF readiness, the free open databases are often enough. BAFU:2025 fits DACH- and EU-oriented industrial screening, material and process comparisons, and PCF readiness; USLCI is useful when North American background data is relevant; and ProBas supports German reference use cases, basic background data, and education.

When results become customer-facing, globally representative, externally scrutinized, or highly specific, a commercial database is usually the better fit. ecoinvent delivers broad sector and geographic coverage for complex products and global supply chains; ecoinvent EN 15804 supports EPD-related and EN 15804-aligned assessments; and Carbon Minds adds depth for chemistry- and plastics-intensive work. A practical path is to start with the free databases and add a commercial one once your requirements grow.
