DEISO's sustainability work is technically directed by Dr. Mahdi Ikhlayel, PhD, Sustainability Science. His role connects technical execution, sustainability operating system architecture, data workflows, review logic, evidence structure, reporting outputs, and AI-supported decision support.

How DEISO's work is directed

Dr. Mahdi Ikhlayel directs DEISO's technical execution system: methodology design, sustainability operating system architecture, data workflows, calculation logic, review steps, quality standards, and delivery frameworks.

This matters because DEISO does not present sustainability work as isolated reports or disconnected tasks. The work is structured so data, assumptions, methods, evidence, outputs, and decisions can be followed and reviewed.

Technical direction means direct involvement in how the method is built, how data is organized, how review logic is applied, and how final outputs support reporting, verification, customers, tenders, or business decisions.

Areas of direct technical expertise

His technical practice covers what DEISO actually delivers:

Sustainability operating systems & architecture
Data workflows, calculation logic, review steps, evidence structure, reporting logic, governance, capacity building, and decision-support design
Life Cycle Assessment (LCA)
System boundary design, ISO 14040/14044 compliant execution, model review, interpretation, and technical reporting
Scope 1–3 GHG Accounting
Emissions data structure, calculation review, Scope 1, Scope 2, Scope 3 workflows, and reporting support
Product Carbon Footprint (PCF)
Product-level carbon accounting for customer requests, procurement needs, disclosure, and reporting requirements
Environmental Product Declarations (EPD)
EPD readiness, data checks, method review, evidence preparation, and verification support
Sustainability data governance
Structured sustainability data, evidence files, review controls, and reporting workflows across ESG, CBAM, CSRD, and compliance needs
Industrial sustainability
Circular economy, cleaner production, resource efficiency, industrial systems, and waste treatment assessment
CO₂ reduction & utilization
Technology assessment, carbon reduction options, utilization pathways, and environmental impact evaluation
Sustainability system digitalization
AI-supported workflows, decision-support tools, dashboard logic, and decision-support system design

The technical logic behind DEISO's tools

DEISO's AI-supported tools and sustainability decision-support systems are designed around real sustainability work, not generic automation. They support how LCA, GHG accounting, PCF, EPD, ESG, technical review, evidence preparation, and reporting workflows are actually handled.

The architecture behind these tools is guided by Dr. Ikhlayel's combined engineering and sustainability background. His role is to define how the systems organize sustainability inputs, route technical questions, support review logic, and help users move from scattered information to clearer decisions.

This keeps the tools connected to expert judgment. AI support is used to organize, interpret, and guide sustainability work, while technical responsibility remains with the expert-led methodology, review process, and system architecture behind DEISO delivery.

Peer review and research contribution

Since 2017, Dr. Ikhlayel has reviewed over 125 peer-reviewed publications across more than 15 international journals — among them the Journal of Cleaner Production, Resources Conservation & Recycling, Waste Management, and Sustainability. He has also reviewed academic book proposals for Elsevier and John Wiley & Sons.

This is not decorative. Sustained peer review at that scale means direct, ongoing exposure to where the field is moving — what methodologies are gaining acceptance, where standards are tightening, what reviewers and verifiers are looking for. That exposure feeds into the standards DEISO applies.

His record is publicly verified on Publons. Publications and academic contributions are available on Google Scholar.

Client Services & Engagement

Speak with DEISO's client services team

DEISO's client inquiries and engagement communication are coordinated by Ms. Yuki Kimura, Client Services Lead. For project inquiries, scope questions, service direction, or next-step coordination, Ms. Kimura is the first point of contact. Technical questions can then be directed to Dr. Ikhlayel when specialist review is needed.

Contact Ms. Yuki Kimura

Clear technical authority. Clear client support.

If you are evaluating DEISO for a sustainability project, technical review, sustainability operating system, or AI-supported sustainability workflow, this page answers two questions: who is technically responsible for the work, and who supports client engagement.

The technical authority is Dr. Mahdi Ikhlayel, PhD, Sustainability Science. Client services and engagement coordination are supported by Ms. Yuki Kimura.

Get Started with DEISO the Easy Way!

Seven ways to start

Choose the entry point that fits where you are

Not every visitor knows what they need on day one. These seven onboarding paths cover the full range — from knowing exactly which service you want to starting from a question and letting AI guide you. Pick whichever fits.

1If you know what you needRecommended Find the right DEISO service Match your requirement to the right DEISO service in a few clicks. Filter by LCA, GHG, PCF, EPD, ESG, critical review, S-LCA, waste, circular economy, EIA, and more. Fastest path if you already know the scope. Good for “We need Scope 3 review and pre-submission checks before verification” or “We need an EPD prepared for EN 15804.” Open service finder → 2If you’re building internal capabilityRecommended Explore capacity building programs Match your team to the right DEISO training program — LCA, GHG accounting, PCF, EPD development, ESG reporting, environmental review, ISO 14001, and sector programs. Filter by role, level and format. Good for Teams building in-house LCA, GHG or EPD capability, and organisations aligned with workforce development priorities such as Saudi Arabia Vision 2030. Open training finder → 3If you need technical direction before engagementRecommended Free Technical Evaluation Request an initial technical evaluation for your sustainability requirement before committing to a full engagement. DEISO reviews your project need, technical context, enterprise requirement, reporting objective, and service direction to help identify the right path. Good for Enterprises, suppliers, and public sustainability teams that need technical direction before starting LCA, GHG, PCF, EPD, ESG, or sustainability operating system work. Start free evaluation → 4If you want an answer fast Use quick search Click the search icon in the page sidebar, or press Ctrl Shift Del to open the finder from anywhere on the site. Built for quick keyword lookups when you want results in seconds. Good for Anyone who already knows the term they are looking for — a standard, a service name, a training program — and wants to land on it without navigating. Open quick search → 5If you want to explore in depth Use advanced search Search across the full DEISO knowledge base — services, solutions, methodology, case studies, articles and technical resources. Best for when you want to research first, decide later. Good for Researchers, procurement teams and technical leads comparing methodology depth before opening a conversation. Open advanced search → 6If you’d rather see everything at once Browse the full site map A single index of every page and every article on the site — services, training programs, solutions, methodology, case studies and news. Filter it as you type, or read the structure top to bottom. Good for Returning visitors looking for a page they have seen before, and anyone who would rather scan the whole structure than answer filter questions. Open the site map → 7If you’d rather ask a questionAdvanced Ask Mirai AI DEISO Mirai™ AI Pro is DEISO’s AI guidance assistant. Ask a question about your sustainability need — it maps you to the right service, explains the approach, and hands off to the DEISO team when you’re ready. Try asking “What do we need to prepare for CSRD Scope 3 disclosure?” · “How do we start a product carbon footprint?” · “Which DEISO service fits an EPD project?” Ask Mirai →
