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 →
