Four ways to start
Choose the entry point that fits where you are
Not every visitor knows what they need on day one. These four 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 need
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 audit and pre-submission review before verification" or "We need an EPD prepared for EN 15804."

2If you'd rather ask a question
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?"

3If you're building internal capability
Explore capacity building programs
Match your team to the right DEISO training program — LCA, GHG accounting, PCF, EPD development, ESG reporting, environmental auditing, ISO 14001, and sector programs. Filter by role, level, and delivery format.
Good for
Teams building in-house LCA, GHG, or EPD capability, and organizations aligned with workforce development priorities such as Saudi Arabia Vision 2030.
