Practical Tools
Decision-grade tools for
sustainability practitioners.
Alongside our advisory work, Glatow & Associates builds focused, audit-grade tools for the specific calculations, evidence steps, and questions our clients return to most often. Every tool is purpose-built, narrowly scoped, and designed to be defensible in front of an external auditor.
Generic carbon calculators rarely survive a real ISCC or REDcert audit. Our tools take the opposite approach: each one is locked to a specific scheme, a specific step in the value chain, and a specific set of methods — with the regulatory references built directly into the calculation trace.
Featured Tool
Transport etd Calculator + AI Advisor
ISCC EU / RED III — Transport & Distribution Emissions, with a built-in AI advisor.
A single-purpose calculator for the transport and distribution stage of biofuel and bioliquid certification. It computes per-leg etd using the five recognised methods (M1–M5), tracks the factor-governance status of each input (default, measured, verified, manual), and generates an audit-ready evidence trail in CSV or JSON format. A scoped AI advisor sits next to the calculator and answers questions only inside the transport sections of ISCC EU 203 / 205, RED II/III, and IR 2022/996.
Calculator engine
- Method M1 — actual measured fuel consumption per leg.
- Method M2 — verified provider-specific factor with documented basis.
- Method M3 — IR 2022/996 Annex IX default efficiencies and fuel emission factors.
- Method M4 — country-specific grid electricity factor with HV / MV / LV voltage levels.
- Method M5 — RED II/III disaggregated default values for transport.
- Optional depot & filling-station distribution add-on.
- Per-leg factor governance: every input is tagged as default / measured / verified / manual and validated against scheme readiness rules.
- Full calculation trace per leg plus CSV / JSON export for audit packs.
AI advisor Beta
- Strict scope: ISCC EU 203 / 205 transport sections, RED II/III transport-related provisions, IR 2022/996 Annex IX (efficiencies, fuel EF, grid EF).
- Retrieval-augmented: grounded in indexed regulatory text rather than free-form generation, with citations.
- Polite refusals for out-of-scope topics (full-chain GHG, GHG saving %, RED pass/fail, RFNBO/RCF, processing/allocation, heat or electricity certification) with a pointer to the right advisory channel.
- Streamed answers (SSE) for fast feedback while typing follow-up questions.
- Per-session and per-IP rate limits to prevent abuse.
- Advisory only. Not a substitute for certified audit, scheme verification, or legal advice. Glatow & Associates accepts no liability for AI-generated responses.

Carbon Audit Dashboard
Co-issued with TVA — Technical Verification Alliance
Plain-language carbon footprinting for freight, travel, hotels, fuel and electricity — with an AI extractor.
A general-purpose Scope 1 / 2 / 3 calculator that turns natural-language descriptions into auditable CO2e numbers. Type "we shipped 2 tonnes from London to Berlin in a diesel truck" and the AI extractor maps it to the right activity, fuel and route, runs it through industry-standard factor databases (DEFRA, GLEC, ICAO, Ember), and returns a per-leg breakdown with full source traceability and a route map.
Categories covered
- Freight & Logistics — road, rail, sea, air with mode-aware fuel mapping (diesel → Jet A-1 for air, HFO for sea, etc.).
- Passenger Travel — flight (with cabin class), car, taxi, bus, rail, ferry; per-passenger-km factors.
- Hotel Stays — country-level factors plus a benchmark mode for cross-country comparison.
- Fuel Combustion (Scope 1) — 16 fuel types from natural gas to wood pellets, in litres, kWh, kg or m³.
- Electricity (Scope 2) — country grid factors or AWS / Azure / GCP cloud regions.
- AI Inference — token-based emissions across 8 LLM providers, with optional cached-token discount.
AI extraction & audit trail Beta
- Plain-language input — supports English and German, asks clarifying questions when ambiguous.
- Multi-activity prompts — extracts several legs from a single sentence (e.g. flight + hotel + fuel).
- Math traceability per row: distance × dimension × factor reproduces the headline number.
- Route map for transport activities (OpenStreetMap-based, with origin/destination markers and waypoints).
- PDF & CSV export with methodology, sources, and a per-row factor breakdown.
- Beta release. Planning aid only — not a substitute for a certified third-party-assured Scope 1/2/3 audit. Sub-processors are listed in our Privacy Policy.

Who Uses This Tool
Built for the people who actually have to defend the number.
Producers & Collectors
Calculate transport & distribution emissions per shipment or per outgoing batch. Maintain an evidence log that supports outgoing Proof of Sustainability (PoS) claims.
Traders & Storage
Assess incoming PoS data, recompute legs where defaults are too conservative, and decide whether to switch a leg from default to actual or verified. Document every change.
Internal Audit & Readiness
Pre-audit your transport calculations before the certification body opens the file. Use the calculation trace and factor-governance flags to find weak spots in evidence quality.
Sustainability Officers
Translate scheme-level requirements into a working calculation that operations teams can actually populate, line-by-line, with the evidence they have on hand.
Consultants & Auditors
Replicate or sanity-check a client's transport etd in minutes. Compare a default-only run versus an actual-data run to quantify the headroom.
Training & Capacity Building
Walk teams through methods M1–M5 in a working environment, with the AI advisor supplying scheme references on demand. A safer learning surface than a production audit file.
How It Works
A defensible number, built one leg at a time.
The calculator does not try to estimate a full-chain GHG saving. It does one thing thoroughly: build a transport & distribution emissions value with a clear, traceable basis for every input.
Step 1
Define each transport leg
Add legs in the order they happened: feedstock collection, intermediate storage transfers, final delivery. Each leg has its own mode (truck, rail, sea, inland barge, pipeline, electric), its own distance, and its own load characteristics.
Step 2
Choose a method per leg
For each leg, decide whether you have actual measured data (M1), a verified provider factor (M2), an IR 2022/996 default (M3), a country grid electricity factor (M4), or a RED II/III disaggregated default (M5). The factor-governance flag tells you immediately whether your choice is defensible against scheme readiness rules.
Step 3
Attach evidence references
Each leg accepts an evidence reference (delivery note number, GPS log ID, supplier certificate ID, pump record reference). The reference travels with the calculation into the audit export — so the same record an auditor would request is already pinned to the leg.
Step 4
Add depot or filling-station distribution (optional)
For final-distribution use cases, add the optional depot & filling-station electricity component, computed as a transport / distribution add-on in gCO2e/MJ (and optionally absolute kgCO2e).
Step 5
Export your audit pack
Export the full calculation trace as CSV or JSON. The export includes per-leg inputs, the chosen method, the factor-governance status, the evidence reference, and the resulting transport etd contribution — together with the regulatory citation per leg.
Step 6
Ask the AI advisor when you are unsure
Whenever a leg surfaces a scheme question (which method is appropriate? does my evidence qualify as M2 verified? what does ISCC EU 205 say about voltage level?) — open the AI advisor panel. It answers strictly within transport scope, cites its sources, and refuses to speculate about anything else.

Frequently Asked
Common questions, answered honestly.
Is the calculator free to use?
Access is free during the current beta phase. You request a code via the calculator's login screen and receive it by email. We may introduce a paid tier later for advanced features (multi-batch portfolios, scheme-specific export templates, deeper AI advisor entitlements). Existing accounts will be communicated to before any change.
Can I use the calculator's output directly in my ISCC audit?
The calculator produces audit-ready evidence (calculation trace, factor-governance flags, evidence references). However, it is your responsibility — and your certification body's — to assess whether the evidence references behind each leg actually qualify as measured, verified, or default under the applicable scheme. The tool documents your inputs, it does not certify them.
Why is the AI advisor in beta?
Because we have not yet tested it across enough edge-case prompts to call it production-grade. It is grounded in indexed regulatory text and refuses out-of-scope topics, but no AI system is infallible. Treat its answers as a starting point for your own reasoning or as a research aid — not as a regulatory opinion. Our advisory team remains the appropriate channel for questions that need to be defensible.
What happens to the data I enter?
The calculator runs in your browser session. Inputs and results stay client-side unless you explicitly choose to export them. The AI advisor does send the question text plus retrieved context to a model provider for inference (rate-limited). We log session-level metadata for security purposes (rate limits, abuse detection); we do not log calculation inputs.
Why is this tool transport-only? Why not a full-chain calculator?
Because narrow tools survive audits better than wide ones. A full-chain GHG calculator would have to make assumptions about feedstock, processing, allocation, and end-use that vary too much per client to belong in a generic tool. The transport stage, by contrast, has well-defined methods (M1–M5), documented defaults, and a clean evidence boundary — exactly the conditions under which a tool can be both useful and defensible.
Can I get the calculator white-labelled or hosted on our own domain?
Possibly. Drop us a note via the contact page outlining the use case (internal teams, external clients, training, etc.). White-label arrangements are handled case by case.
I see a bug or a value that looks wrong. What do I do?
Email us with the leg setup that reproduces it (mode, distance, factor source, evidence reference). The calculator's data tables are versioned and regenerated from a single Excel master, so corrections propagate cleanly.
