About Luminoko
Luminoko is a free tool for getting instant Product Carbon Footprint (PCF) estimates for any product. Describe something — from a water bottle to a washing machine — and get a detailed breakdown of its production emissions in minutes, not months.
We built Luminoko because getting even a rough sense of a product's carbon impact shouldn't require a consultancy engagement and a six-figure budget. Whether you're an engineer choosing between materials, a buyer comparing suppliers, or just someone who's curious — you deserve a quick, honest answer.
Luminoko isn't a replacement for a verified Product Carbon Footprint. It's the step before — a transparent, directional starting point that helps you understand where the carbon sits before you invest in deeper analysis.
What people use Luminoko for
Product design & innovation
Comparing material choices early in the design process. If you're deciding between aluminium and steel housings, or cotton versus polyester, Luminoko gives you a directional answer in seconds — before you commission expensive testing or formal PCF assessments.
Portfolio screening & CSRD compliance
Companies facing Scope 3 Category 1 reporting obligations often have thousands of SKUs and no way to prioritise which need detailed assessment. Luminoko gives you a directional answer across your entire range in hours, not months — so you can focus expert time and budget where it matters most.
Supplier & procurement decisions
Compare the estimated carbon intensity of alternative suppliers or materials before you have formal data. Useful for building the business case for a switch before you have formal Scope 3 figures.
Sustainability strategy & prioritisation
Understanding which products in your range are likely the biggest emitters, so you can focus detailed assessment and reduction efforts where they'll have the most impact.
Education & awareness
Teaching teams, students, or consumers about the relative scale of carbon impacts across everyday products. A cotton t-shirt vs. a pair of jeans. A glass bottle vs. a PET one. The numbers often surprise people.
Research & scoping
Getting a ballpark figure to include in a proposal, report, or business case — when you need a credible starting point but don't yet have the budget or timeline for a full third-party assessment.
Curiosity
Sometimes you just want to know. What's the footprint of a banana? A laptop? Your morning coffee? Luminoko is built for that too.
Frequently asked questions
Is Luminoko free?
Yes. Luminoko is completely free to use.
How accurate are the estimates?
Every estimate includes a confidence interval that reflects the quality and availability of underlying data. Well-studied products (like common electronics or basic food items) will have tighter ranges. Novel or niche products will be wider. The numbers are directionally reliable — good enough to compare options and spot hotspots, but not a substitute for a verified Product Carbon Footprint.
Can I use these numbers in a report?
You can reference them as AI-generated estimates for informational purposes. They should not be used for regulatory compliance, formal carbon reporting, or public environmental claims. If you need audit-grade data, Luminoko is a good starting point to identify which products to prioritise for full assessment.
Why does Luminoko sometimes ask me to choose between options?
Because specifics matter. A "water bottle" could be a single-use PET plastic bottle or a reusable stainless steel one — and the carbon footprint differs by a factor of 20x. When a description is ambiguous, Luminoko asks a clarifying question to make sure you get the most relevant estimate.
What scope do the estimates cover?
Estimates cover the production lifecycle: raw material extraction, transport to manufacturer, and manufacturing (cradle-to-gate, or A1–A3 in EN 15804 terms). This is the scope most relevant for Scope 3 Category 1 reporting under CSRD. Where sufficient data exists, estimates may also include distribution, use phase, and end-of-life modelling — but the core scope is always cradle-to-gate.
How does Luminoko get its numbers?
Under the hood, Luminoko uses a third-party carbon intelligence engine called ecozeAI (built by ECOZE Ltd) to do the heavy lifting. We evaluated several approaches and chose ecozeAI because it goes far beyond the rough category averages most carbon calculators rely on.
When you submit a product description to Luminoko, the ecozeAI engine:
-
Infers an AI-estimated Bill of Materials by researching global disclosures, patent filings, customs data, and product teardowns
-
Calculates a cradle-to-gate Product Carbon Footprint following methodology consistent with ISO 14067:2018 and ISO 14040/14044
-
Scores data quality across five dimensions (reliability, completeness, temporal representativeness, geographical representativeness, and technological representativeness) using the GHG Protocol's Pedigree Matrix
-
Quantifies uncertainty using the GHG Protocol's Pedigree Matrix methodology, scoring data quality across five dimensions to produce confidence intervals — not just a single number
-
Assembles a complete evidence locker of supporting documentation so every estimate can be examined, challenged, and understood
The engine draws on emission factors from leading databases including ecoinvent and DEFRA Conversion Factors. It doesn't just look up numbers in a table — it reasons about supply chains, manufacturing processes, and material compositions, cross-referencing multiple data sources to build a picture of how a product was made and what that means for its carbon footprint.
This is the kind of analysis that traditionally takes weeks and costs thousands of pounds. Luminoko makes it available to anyone, instantly, for free.
What this is — and what it isn't
The estimates on Luminoko are AI-generated and intended for informational purposes: exploring, comparing, and understanding the relative environmental impact of products.
They are not verified or certified Product Carbon Footprints. They are not suitable for regulatory compliance, formal carbon reporting, or making public environmental claims about specific products. Think of them as the most informed starting point available without commissioning a full third-party assessment.
Luminoko is designed for screening and comparison — the step before formal assessment. If your organisation needs audit-ready Product Carbon Footprints, supply chain Scope 3 data, or outputs suitable for CSRD disclosure, the carbon intelligence engine behind Luminoko is available for enterprise use.
