Sustainability operating systems we build
We build the system behind your sustainability work — data workflows, review steps, reporting logic, evidence handling, and governance — across LCA, GHG, PCF, EPD, ESG, and AI-supported execution.
Data your reviewer and customers accept
We move you from scattered files and unclear assumptions to organized data your team, your reviewer, your customers, and your tender questions can all rely on.
14+ years of LCA and environmental practice
Long practical experience in Life Cycle Assessment, environmental modeling, carbon accounting, and sustainability methods. That experience keeps weak assumptions, unclear methods, and unreliable results out of your work.
The technical work your sustainability program needs
LCA models, Scope 1–3 GHG inventories, product carbon footprints, EPD-ready files, ESG data workflows, technical review, and reporting support — built so your team can use them after delivery.
Execution-based capacity building
We help your internal team understand and operate the systems and methods we deliver. Capacity is built around the actual work, so your people can run the next cycle instead of starting from zero.
Support from first review to delivery
We can step in at any stage: reviewing your current data, defining the scope, executing the technical work, checking outputs, and preparing evidence for verification or customer requests.
Global delivery across 35+ countries
Work delivered across 35+ countries gives us range across sectors, data conditions, reporting frameworks, and international sustainability requirements.
Technical work done properly
Enterprises, suppliers, and public sustainability teams choose DEISO when the technical work has to hold up. We deliver sustainability work that is repeatable, defensible, and ready for verification.

What makes DEISO different
Why companies choose DEISO for sustainability work
- Sustainability operating systems, not scattered outputs
We build the structure behind your sustainability work — data workflows, review steps, reporting logic, evidence files, governance, and team support — so your LCA, GHG, PCF, EPD, ESG, and AI-supported work runs as one program instead of disconnected files. - Technical execution, not only advice
We do the work: organize your data, build the models, check the methods, review the outputs, prepare the evidence. You get a finished file, not a list of recommendations. - Clear support for LCA, GHG, PCF, EPD, and ESG
Life Cycle Assessment (LCA), Scope 1–3 GHG accounting, Product Carbon Footprint (PCF), Environmental Product Declaration (EPD) readiness, ESG data workflows, and technical reporting support — all under one team. - Technical review before reporting or verification
We find weak data, unclear assumptions, method gaps, calculation errors, and missing evidence before your work goes to a reporting framework, a customer, or a verifier. - Data made easier to manage and explain
We turn scattered sustainability data into organized information your team can check, update, explain, and reuse for customers, tenders, reporting, verification, and internal decisions. - Execution-based capacity building
We help your internal team understand the methods, workflows, files, and systems we deliver. Capacity is built around the actual project, so your people can run the next cycle without starting from zero. - AI-supported workflows where they help
We use AI-supported workflows for data organization, review, interpretation, and decision support. Technical judgment and expert review stay at the center. - Global delivery across 35+ countries
Work delivered across 35+ countries gives us range across sectors, data conditions, reporting frameworks, and international sustainability requirements. - Repeatable systems for future work
We build the next cycle into the first one. Your LCA, GHG, PCF, EPD, ESG, and reporting work becomes a system you can rerun — not a project you have to restart from scratch. - Outcomes you can use
Enterprises, suppliers, and public sustainability teams choose DEISO when the work has to hold up. We deliver sustainability work that is repeatable, defensible, and ready for verification.
