Book & Claim for clean fuels (SAF, marine biofuels, renewable road fuels)
Make clean-fuel action scalable — and commercially bankable.
VURDHAAN designs and runs Book & Claim programs in alignment with ISO 13659 so transport operators and fuel users can fund verified decarbonisation even when physical supply isn’t available at every hub — and recover sustainability costs by packaging the verified Scope 3 benefit for corporate customers.
- Integrity first: unique units, retirement controls, and audit-ready evidence trails.
- Multi-sector: aviation, maritime, road & rail — one governance model, tailored execution.
- Claims that stand up: aligned with recognised accounting & reporting approaches.
The challenge isn’t ambition — it’s attribution.
Sustainable fuels and fleet upgrades are costly, supply is uneven, and claims are increasingly scrutinised. Book & Claim lets you decouple where the clean fuel happens from who funds it — without losing credibility.
Problem
Physical clean-fuel access is inconsistent across hubs, routes, and ports. Procurement teams struggle to match sustainability goals with real-world logistics.
Impact
You absorb costs without a scalable mechanism to allocate benefits — risking under-delivery on targets, and over-claiming in reports and marketing.
Solution
Build an integrity-first Book & Claim program: verified units, clear allocation rules, and customer-ready Scope 3 products (biofuel units or fleet-renewal-linked credits), supported by evidence and governance.
Our approach (Based on ISO 13659)
We focus on governance, measurable outcomes, and commercial deployment — not “quick fixes.”
-
Define the commercial outcome
Who pays, who claims, and how value is priced (insetting, customer products, internal targets, compliance).
-
Design the Book & Claim rulebook
Allocation methodology, unit definitions, boundaries, anti-double-claim controls, and communications guardrails.
-
Secure supply & perform due diligence
Feedstock and lifecycle checks, certification review, supplier vetting, registry integrity, and contract structure.
-
Operate issuance, transfer, retirement
Evidence trail, unique IDs, retirement statements, and a clean “who claimed what, when” ledger.
-
Make it reportable — and sellable
Scope 3 allocation packs for customers, auditor-ready documentation, and market-facing claims language.

Services for Book & Claim programs
Outcome-led support across strategy, procurement, governance, operations, and reporting.
Program strategy & commercial design
Translate sustainability goals into a marketable offering and internal decision model (pricing, allocation, customer packaging).
Benefit: clearer ROI story and faster internal buy-in.
Framework & governance (“rulebook”)
Define unit boundaries, eligibility, claims language, and controls to prevent double claiming and greenwashing risk.
Benefit: credibility that withstands stakeholder scrutiny.
Supplier & registry due diligence
Assess fuel sustainability evidence, lifecycle emissions data, chain-of-custody, registry controls, and retirement mechanics.
Benefit: fewer surprises post-purchase; stronger audit position.
Procurement & contracting support
RFP design, negotiation support, contract clauses for evidence, delivery confirmation, issuance, and retirement requirements.
Benefit: reduced delivery and reputational risk.
Scope 3 allocation packs for customers
Customer-ready documentation that explains allocation logic and what can/can’t be claimed in value-chain reporting.
Benefit: smoother sales cycles and fewer customer objections.
Assurance-ready reporting & comms
Evidence indexing, calculation memos, reporting narratives, and public-facing claim wording designed to avoid overstatements.
Benefit: confident reporting under rising disclosure expectations.
Proof of expertise you can validate
Book & Claim only works when it’s built on clear rules, credible units, and recognised accounting logic. We align your program to the frameworks your stakeholders reference.

Two interactive views: integrity flow + value recovery
Click through the mechanics and see how Book & Claim can turn decarbonisation into a customer-facing Scope 3 product — whether you’re using biofuels today or financing fleet renewal over time.
Interactive: How Book & Claim works (with integrity controls)
Select a step to reveal what must be true for credible claims.
Selected step
Produce & certify
Confirm sustainability certification and lifecycle basis. Define what “eligible” means for your program (feedstocks, boundaries, audit evidence) before any units exist.
- Eligibility criteria + documentation pack
- Lifecycle emissions approach defined upfront
- Supplier auditability assessed
Interactive: Value recovery engine (biofuels vs fleet renewal)
Book & Claim can support near-term fuel insetting and longer-term transition investments — if the unit definition and claims logic are sound.
What you fund
Verified use of sustainable fuel in a defined fuel pool (airport, port, depot), issued as transferable units.
What customers buy
A retired unit allocated to their activity (travel, freight, shipments) with a documentation pack for their Scope 3 narrative.
How costs are recovered
You transform premium fuel spend into a priced customer product — improving margin resilience and accelerating uptake.
What you fund
Measurable transition outcomes from fleet upgrades (efficiency, alternative powertrains, retrofit or renewal), translated into a governed crediting logic.
What customers buy
A defined share of verified value-chain reduction tied to service use — packaged with boundaries, methods, and evidence to support their reporting stance.
How costs are recovered
You attach transition investment to customer demand — converting capex into long-term commercial differentiation and contracted revenue.
Note: customer “Scope 3 credit” acceptance depends on their reporting policies and assurance expectations. We design the unit, evidence pack, and claims language to reduce friction and avoid over-claiming.
Key deadlines & requirements (example: EU)
These EU milestones often drive first-mover Book & Claim programs. Other jurisdictions differ — we map your obligations and opportunities by region.
FuelEU Maritime: regulation fully applied from 1 Jan 2025; GHG intensity reduction target -2%.
FuelEU Maritime: GHG intensity reduction -6%; OPS / zero-emission at berth obligations begin in certain ports.
FuelEU Maritime: step-up to -14.5% (2035), -31% (2040), -62% (2045), -80% (2050).

If Book & Claim is your core lever, treat it like infrastructure.
We help you build a program that is operationally workable, commercially compelling, and defensible under scrutiny — so you can scale sustainable fuels and recover costs through customer-backed Scope 3 value.
- We understand your context: mode(s), geography, customer demand, current supply constraints.
- We outline a pathway: governance model, unit definition, supplier/registry approach, and reporting guardrails.
- We propose a delivery plan: scoped workstreams and clear roles across sustainability, procurement, and commercial teams.
We’ll respond with next steps and the information we need to assess feasibility — no generic pitch decks.
