DEISO LCA Database
Life cycle inventory and impact assessment in Excel and openLCA formats
A life cycle assessment database built by DEISO from openly licensed life cycle inventory data. Every process carries its cradle-to-gate emission factors, ready for impact assessment. DEISO uses it in its client LCA projects and in capacity building (training).

An LCA database built and maintained by DEISO
DEISO develops its own data. The DEISO LCA Database turns openly licensed life cycle inventories into one library of emission-factor processes: one product, its complete cradle-to-gate elementary flows, traceable to its source.
Emission-factor processes from openly licensed life cycle inventory data and DEISO's own grid mixes.
AGRIBALYSE 3.2 Core, USLCI, USDA crop data and data derived from the ELCD III data sets.
DEISO electricity grid mixes built from Ember generation shares and power-plant inventories.
EF 3.1 with normalisation and weighting, TRACI 2.1 and 2.2, US EPA inventory indicators and DEISO GWP: 53 indicators.
Fifteen industry case studies, from concrete to data centres, plus five empty starting models.
An Excel workbook and an openLCA 2.x database, built from the same data.
From open inventories to ready emission factors
- Openly licensed sources only — every data source and method is published under terms that allow modification, redistribution and commercial use, with attribution.
- Emission-factor processes — every library process holds one product and its full cradle-to-gate resources and emissions, so models calculate directly.
- Exact results — no cut-off is applied and every elementary flow is kept, so results match the linked source data for any method.
- Transparent gaps — processes with partial background data carry a data completeness note, so their results are read as lower bounds.
One product, its full cradle-to-gate inventory, ready for impact assessment.
In DEISO client projects and capacity building
- Client LCA projects — product and service life cycle assessments for DEISO clients, modelled in openLCA and checked in Excel.
- Capacity building (training) — fifteen worked industry case studies and five templates that trainees complete with their own data.

Results built from average life cycle inventory data are estimates. Where supplier-specific or measured data are available, they give a more accurate picture of a product's impacts.
About the DEISO LCA Database
What is the DEISO LCA Database?
The DEISO LCA Database is a life cycle assessment database developed by DEISO from openly licensed life cycle inventory data. It holds 23,267 emission-factor processes, including 202 DEISO country electricity grid mixes, with five impact assessment methods and 15 industry case studies, in an Excel edition and an openLCA 2.x edition.
Who developed the DEISO LCA Database?
DEISO LLC developed and maintains the DEISO LCA Database. DEISO built the data pipeline, the emission-factor computation, the cross-database linking, the country grid mixes, the case studies and the templates.
What is an emission-factor process?
Each library process contains one product and its complete cradle-to-gate elementary flows: the resources it takes from nature and the emissions it releases, per unit of product. A model only needs the activities and their amounts; the database already carries the supply chain behind each one.
Which impact assessment methods are included?
EF 3.1 (European Commission, Joint Research Centre) with its normalisation and weighting set, TRACI 2.1 and TRACI 2.2 and the FEDEFL inventory indicators (US Environmental Protection Agency), and DEISO GWP for IPCC AR6 and AR5 global warming potentials: 53 indicators in total. Every elementary flow is kept, so further methods can be added in openLCA.
Which data sources does it use?
AGRIBALYSE 3.2 Core (ADEME), USLCI and USDA crop data (US Federal LCA Commons), data derived from the ELCD III data sets (European Commission) and Ember electricity data for the grid mixes. Each source is openly licensed, credited and kept under its provider's terms.
Which industries do the case studies cover?
Cement and concrete, steel, aluminium, plastics, oil and gas, power generation, hydrogen, agriculture, food and beverage, textiles, electronics, automotive batteries, construction, packaging and data-centre services.
How does DEISO use the database?
In DEISO client LCA projects and in DEISO capacity building (training), where trainees work through the industry case studies and build their own models from the templates.
How accurate are the results?
Results built from average life cycle inventory data are estimates. Processes whose source data have partial background coverage carry a data completeness note, and supplier-specific data give a more accurate result where available.
