DEISO Sansu Pro: one desktop engine for LCA, S-LCA, GHG, PCF and EPD data
Search less. Model more.
Built by DEISO LLC to find, compare and model life cycle data across 33 databases, from one search to a full study. DEISO Sansu Pro is in-house software within the DEISO Sustainability Operating System. DEISO uses it on client projects and in renforcement des capacités, so every study starts from traceable data, applied with the methods and review steps the system defines.
- 206,439LCA processes
- 33databases: 31 LCA, 1 S-LCA, 1 GHG
- 3,816S-LCA country-specific sectors in 189 countries
- 4study types with flowcharts: LCA, S-LCA, GHG inventory, empreinte carbone du produit
- Up to 90%less time spent searching for processes
For the LCA databases it searches, DEISO Sansu Pro holds metadata only — process names, descriptions, locations and classifications — to help find the right dataset. It does not hold their inventory data, exchanges or results. Data with values comes from DEISO’s own databases — DEISO LCA (Internal) Database, DEISO LCA (External) Database, DEISO S-LCA (External) Database et DEISO GHG Base de données — and from public sources credited in the app.
DEISO Sansu Pro inside the DEISO Sustainability Operating System
DEISO développe Systèmes opérationnels de durabilité: the data, methods, workflows, governance and review steps that keep LCA, Comptabilisation GHG, empreinte carbone du produit (PCF), EPD and ESG work repeatable and defensible. Where software makes that work faster or more reliable, DEISO builds it in-house. DEISO Sansu Pro is one of those tools.
- Appliquer les bonnes méthodes — process identification matched to the LCA, S-LCA, GHG or PCF method a study follows.
- Exécuter un workflow maîtrisé — every dataset is found, compared and cited with its source, ready for review.
- Développer les logiciels nécessaires — DEISO Sansu Pro is in-house software DEISO builds for the operating system.
- Keep capability in the team — used in DEISO execution-based renforcement des capacités on real projects.
DEISO Sansu Pro is used only on DEISO client projects and in capacity building. It supports the system; people remain responsible for technical review and final decisions.
The first desktop engine designed to search and identify processes across LCA databases
To the best of our knowledge, no other locally installed application has been designed to intelligently search and identify processes across databases. Developed in-house by DEISO LLC, DEISO Sansu Pro searches and identifies LCA processes, S-LCA country-specific sectors and GHG data across 33 databases in one local search, and builds the study for the method you choose: an LCA product system, an S-LCA social supply chain, a GHG inventory across all 22 GHG Protocol categories, or a empreinte carbone du produit, each with its own flowchart.
It supports technical execution across LCA, EPD, PCF, S-LCA and Comptabilisation GHG: finding the right process, comparing systems stage by stage, suggesting an equivalent in another database or region, and keeping a traceable record of every dataset chosen. AI-assisté query understanding helps with the search; people remain responsible for technical review and final decisions.
Execution-focused data identification for repeatable sustainability work
Finding the right process is one of the slowest steps in LCA, PCF, EPD, S-LCA and Comptabilisation GHG work. The same material appears under different names, in different databases, regions and system models, and checking each one by hand takes hours on every project. DEISO Sansu Pro removes that bottleneck: it searches all 33 databases at once and shows the candidates side by side, with their database, version, location and description.
Because every dataset is chosen from a traceable record and cited with its source, the work stays consistent from one project to the next and is review-ready when a critical reviewer or verifier asks how each process was selected.
DEISO Sansu Pro applies DEISO’s own identification engine. It reads a plain-language request, works out the product, country, lifecycle stage and method, and returns the best-matching process from each database. Results can then be compared stage by stage, replaced with an equivalent from another database or region, and collected into a model basket with citations.
With AI-supported query understanding, a conversational chat that answers from the results on screen, and four ways to search, from instant keyword search to a full assistant, process identification becomes a structured, repeatable step rather than a manual task.
Built for process identification at the scale of real projects
DEISO Sansu Pro turns process identification into a structured, repeatable step across LCA, EPD, PCF, S-LCA and Comptabilisation GHG work. These are the features DEISO uses on client projects and in capacity building.
Intelligent process identification
Describe the product or process in plain language. DEISO Sansu Pro works out the material, country, lifecycle stage and method, then returns the best-matching process from each database.
33 databases in one local search
206,439 LCA processes from 31 LCA databases, plus the DEISO S-LCA and GHG databases, searched together and filtered by database, country and lifecycle stage.
One switch for LCA, S-LCA and GHG
Choose LCA, S-LCA, GHG or all three. Every search, study and comparison follows the data type selected, and the app asks before building a study that does not match it.
Four ways to search
Instant keyword search with no AI, Simple and Advanced modes for detailed results, and an Assistant that builds a complete study from one request.
Studies with their own flowcharts
An LCA product system, an S-LCA social supply chain of country-specific sectors, a GHG inventory across all 22 Protocole GHG categories, and a empreinte carbone du produit with lifecycle and scope views.
Structured LCI modelling wizard
Five guided steps take a product from goal and scope to a cradle-to-grave model, grouped into six lifecycle stages, with the best match in each database you select.
Upstream and downstream processes
See the processes that feed a dataset and where its output goes, so the system boundary is set deliberately rather than by default.
Compare systems stage by stage
Two or more products or materials are aligned by lifecycle stage and role, with a confidence level on every match and the full database name and version.
Alternatives and substitution
Find an equivalent process in another database or region, rank the candidates, and compare the top three with the original in one step.
Processes and activity data from files
Analyse PDF, Word and Excel files to extract the processes and activity data they describe, match each one to a dataset, and add them all to a model.
Chat with results
Ask follow-up questions about the results on screen. Answers refer to the records shown, can search the local databases while answering, and show every search made.
Traceable, review-ready outputs
Collect chosen datasets in a model basket with notes and lifecycle coverage, cite them in APA, ISO, RIS or BibTeX, and export to Excel or PDF for review.
Execution challenges DEISO Sansu Pro solves
The slowest and least consistent part of most sustainability studies is not the calculation but finding and justifying the right data. These are the problems DEISO Sansu Pro was built to remove.
Hours of manual research on every project
Checking database after database by hand is the slowest part of the data stage. DEISO Sansu Pro searches all 33 databases in one local search and shows the candidates side by side, so the research takes minutes rather than hours.
The same material under different names
A material appears under different names, regions and system models in each database. The identification engine matches by meaning, not by spelling, and returns the best match from each database for LCA, PCF, EPD, S-LCA and Comptabilisation GHG travail.
Data search holding back the model
Projects stall while the inventory is still being searched. The wizard and the assistant turn one request into a structured model by lifecycle stage, so the team reaches modelling and review sooner.
Database knowledge held by a few people
Knowing which database fits which product usually lives in one or two heads. In DEISO capacity building, participants work with the same engine on real cases, so that knowledge becomes a shared, repeatable method.
Inconsistent process selection
Two analysts can pick two different datasets for the same input. DEISO Sansu Pro ranks the candidates the same way every time and shows a confidence level on each match, so selections stay consistent across projects and teams.
Weak traceability at review
When a reviewer asks why a dataset was chosen, the answer has to be on record. Every selection is kept with its database, version, location and citation, ready for critical review or verification.
Studies structured to recognised methods
Each study type in DEISO Sansu Pro is structured to the standard or guideline that defines the method. DEISO applies the method and the review; the software keeps the structure and the data choices consistent.
| Méthode | Standard or guideline | How studies are structured |
|---|---|---|
| ACV | ISO 14040 et ISO 14044 | Goal and scope, system boundary (cradle-to-gate, gate-to-gate, cradle-to-grave) and processes grouped into six lifecycle stages. |
| PCF | ISO 14067 | Product carbon footprint by lifecycle stage, with a scope view that tags each activity with its GHG Protocol category; GWP100 from IPCC AR6. |
| Comptabilisation GHG | GHG Protocol Corporate Standard and Scope 3 Standard | Inventories across Scope 1, Scope 2 (location-based) and all 15 Scope 3 categories, split into upstream and downstream. |
| EPD | EN 15804 | EN 15804-based datasets for construction product work, searched alongside the general LCA databases. |
| l’ASCV | UNEP Guidelines for Social Life Cycle Assessment (2020) | The supply chain as country-specific sectors, with 29 indicators for workers, local community and society. |
From one request to a reviewed study
DEISO Sansu Pro is used only by DEISO, on client projects and in capacity building. On both, the work follows the same five steps.
- Describe the needA product, an organisation or a question, in plain language, with the data type set to LCA, S-LCA, GHG or all three.
- Identify the dataOne local search across 33 databases returns the best match from each, with database, version, location and description.
- Compare and chooseCandidates are compared stage by stage, and an equivalent from another database or region is found where needed.
- Build the studyThe assistant or the wizard turns the choices into a structured study with its own flowchart.
- Review and citeEvery dataset is kept in a model basket with its citation, then exported to Excel or PDF for technical review.
DEISO uses DEISO Sansu Pro in LCA, PCF, EPD, S-LCA and GHG accounting projects, so data selection is fast, consistent and documented before the model is built and reviewed.
In DEISO execution-based capacity building, participants work through real cases with the same engine and learn how datasets differ across databases, regions and methods.
