Why this source matters
It is the implementation document behind the one paragraph Hitachi’s Sustainability Report 2026 gives to CVP on p. 36. Where the report states an intention, this white paper gives the defining equations, the value-network extension, the standards route (ISO and WBCSD, with named committees), and — the part that matters most here — a verbatim record of the obstacles the study group itself identified, including the disclosure problem, with its proposed answers.
It also corrects two things the wiki got wrong earlier the same day. See “Corrections this source forces”, below.
Page numbering corrected ⟨2026-10-29⟩. The citations in the first half
of this page were one too high, and the appendix citations used the PDF’s
1-based physical page number instead of the printed one. The document has
three unnumbered front-matter pages, so printed page = PDF page − 3:
printed p. 1 is PDF p. 4, printed p. 12 (the standards-route conclusion) is
PDF p. 16, printed p. 15 (references) is PDF p. 19. All inline citations on
this page have been re-anchored to the printed numbers and spot-checked
against the PDF text; the p. 8 citations in sections 5–6 were already
correct. The page ranges in the Sources footers of
CVP,
value networks,
CECRL,
WBCSD and the
CE Association were
shifted by the same rule; where a range endpoint could not be pinned to a
specific printed page it was left as it stood and is marked there.
1. What CVP actually is: a financial ratio
“CVP is an indicator that applies the general definition of productivity to CE–oriented business activities.” (p. 2)
CVP = Y_CE / E_CE (1)
CVP = (S_CE − I_CE) / (C_CE + G_CE) (2)
Value added from circular actions over expenditure on circular actions — where, in Eq. (2), the terms are standard financial-statement items: sales, intermediate goods costs, cost of goods sold, and SG&A, with value added computed by the subtraction method (p. 3).
Three consequences the paper draws itself:
- It is “easy for companies to understand and also highly compatible with common financial analysis processes.”
- “Because GDP is defined as the aggregation of value added, CVP can conceptually relate firm-level activities to economic growth at the national or regional level.” ⟨Inference: this is the feature that makes CVP a policy instrument and not only a management one — and it is why METI and the Ministry of the Environment sit in the room.⟩
- Cross-sector comparison needs normalisation, because “differences among industries in financial structure and cost structure may affect the results” (p. 3).
Evidence offered: in a remanufacturing case, CVP correlated positively with operating profit while WBCSD’s Circular Material Productivity (CMP) “remained largely unchanged” — presented as proof that CVP is complementary to existing CE indicators, and that combining them is “essential not only for comprehensive assessment but also for preventing greenwashing and ensuring the credibility of CE strategies” (p. 3).
2. The gap claim, substantiated
The Appendix is a survey, not an assertion: ~1,400 CE indicators gathered from 34 types of resource material (ISO and other international bodies, corporate ESG reports, national and local policy material, academic papers) → ~770 after merging synonyms → 45 after recategorising onto METI’s Circular Partners indicator set.
Mapped onto six assessment scopes × eleven assessment items, no indicator among the 45 occupies the “focus on cost and value added” cell except CVP itself (#38, source “H-AIST”) — and none is supplied there by CTI, ISO 59020 or ISO 59040 either: “there is also a shortage of indicators from this perspective internationally” (p. 12).
⟨Inference: the diagnosis on which the whole proposal rests is therefore evidenced rather than claimed, and it should be conceded without argument. The interesting question was never whether the gap exists.⟩
3. Value networks — the part Tell Münzing asked about
The paper’s own framing (pp. 1–2):
“in circular business, value creation is not usually completed by individual organizations, but instead value networks (VNs) are formed whereby multiple organizations cooperate through the provision of products, components, and services. Accordingly, when assessing the sustainability of circular business, it is essential to capture the economic efficiency of not only individual organizations but also of entire networks.”
The VN definition “conforms with ISO 59004”, and “the criteria for VN are expected to be made concrete in ISO 59011 and other future standards” (footnote 1, p. 2) — i.e. what counts as a value network is not yet defined.
CVP_VN = Σ(S_CE,i − I_CE,i) / ( Σ(C_CE,i + G_CE,i) − Σ C_D,i ) (3)
Each participating organization i computes its own numerator and denominator contributions; these are aggregated; and C_D — the purchase costs of resources exchanged within the VN, “including materials, products, services, information, and other items” — is subtracted from the denominator to prevent double counting (p. 4).
So the metric’s definition does cross the company boundary. This is the finding that corrects the wiki, and it should be stated plainly rather than softened: CVP is not a firm-boundary metric by construction.
What does not cross the boundary is the computability. From the study
group’s own obstacle list (Table 1, recovered in full in
tables-recovered-from-pdf.md):
“The disclosure of numerator and denominator data within VNs is difficult.”
• “Data management by financial and other institutions as third parties is also possible.” • “Disclosing numerator and denominator values within a VN can be expected to have an effect in maintaining equity among the stakeholders that comprise the VN.”
And for the single-organization case:
“The disclosure of data used in CVP calculation is difficult.”
• use CVP “internally without disclosure”, at least initially • “third-party certification to have just the final CVP value certified” • “conversion to data that can be disclosed, such as year-on-year comparisons”
⟨Inference: this is the confidentiality gap arriving in a document written by the standard’s own authors, stated as an obstacle, with four proposed remedies — all four of which are trust arrangements rather than verification mechanisms. Internal-only use abandons the network; third-party certification of the final value moves the trust to an auditor; year-on-year conversion discards the level; custody by “financial and other institutions” installs a data trustee. None makes a figure checkable without disclosure. The gap is not an oversight here, it is a known blocker with no instrument against it.⟩
⟨Inference: the second bullet is the more important one, because it names why the data matters — “maintaining equity among the stakeholders that comprise the VN”. That is a statement about dividing a surplus, not about measuring an environment. It places CVP_VN squarely in the bargaining-failure column: each party needs the others’ figures to know its fair share, and each refuses to supply them because they expose its cost base.⟩
Two further boundary findings from Table 1:
- Definitional circularity, acknowledged: “In the case of VNs, this may depend on whether or not the VN is a CE.” Whether a network is in scope depends on a CE definition that the same table records as unsettled.
- The CE ratio problem: separating CE business from existing business “with some sort of ratio (i.e., a CE ratio) will be necessary”, and the group’s answer is that “companies are undoubtedly calculating costs internally … so this should be left up to the companies”, mitigated by “a simple certification system and guidelines”. ⟨Inference: the segmentation that determines the whole numerator is delegated to the reporting entity, with certification as the only check. This is the spend-based-Category-1 pattern again, one level up.⟩
4. The standards route (ISO and WBCSD)
ISO. Stated reason for going there first is trade law, not measurement: “ISO standards have strong efficacy in the World Trade Organization’s Agreement on Technical Barriers to Trade and contribute to avoiding nontariff barriers in international trade” (p. 8). Concrete path:
- CVP-related descriptions added to an annex of ISO/AWI 59011 (Circular economy — Organizing a value network towards circularity, under development, complementing ISO 59010:2024), “positioned as one element of economic assessment in CE-oriented business”;
- then definition and calculation methods debated in ISO/TC 323 Working Group 3;
- “with the possible future adoption of CVP as an ISO indicator also being considered.”
WBCSD is described as “strengthening its role as a de facto industry standard–setting body through international frameworks formulated by corporate initiative”, with the Global Circularity Protocol (GCP) and Circular Transition Indicators (CTI v4.0) as the levers. Concrete action: “position CVP within the GCP and combine it with existing indicators (e.g., CMP and CTI Revenue) in order to enable assessment that includes economic aspects” (p. 8). Running alongside: BRIDGE Initiative 3, a Japanese Ministry of the Environment project feeding value-chain circularity indicators and corporate disclosure-scheme outcomes into the GCP under development.
A sequencing tension, left unresolved in the source. Table 1’s standardization row records the view that “it would be best to first push the cause at WBCSD; and as value added varies by industry, standards should be discussed and addressed individually at the ISO” — while the response column says “after standards for VNs are addressed, one option will be to prioritize influencing WBCSD”, and §5.1 puts ISO 59011 first. The group has not settled whether the de-facto route or the de-jure route leads. ⟨Represented, not resolved.⟩
5. Other scope limits stated by the group
- Not a product metric. “Fundamentally CVP is intended to be used at the level of businesses to national governments”; per-product calculation is “theoretically possible”, but “a different indicator may be better for product promotion.”
- Not for long-payback assets. “There are presently issues in using annual CVP values for infrastructure and construction businesses with long investment and recovery periods. Our assumption is that CVP will first be used in electrical, electronic, and service fields.”
- The demand is assumed, not shown. “There do not appear to be clear benefits justifying the work-hours required for calculation” is recorded as an objection; the answer is internal use first, financial-institution presentations later. The sustainable-finance linkage is aspirational: “financial institutions are seeking an easily understood CE indicator, and CVP could be a candidate.”
Corrections this source forces
- CVP’s inputs are financial, not material. The CVP concept page asserted on 2026-10-16 that CVP’s numerator “requires material composition, origin, prior use and remaining lifetime”, and used that to argue a direct dependence on digital-product-passport-type data. Eq. (2) refutes it: the inputs are sales, intermediate goods costs, COGS and SG&A. Corrected on the page. The dependence on a DPP is indirect at most — via whatever evidences that a given revenue line is a circular one.
- CVP is not boundary-limited by construction. Eq. (3) is defined over a multi-organization value network. The company-boundary thesis survives only in its sharper form: the definition reaches across the network, the computability does not, and the remedies on offer are trust arrangements. Corrected on the page.
⟨Both errors came from inferring the metric’s data requirements from a single paragraph of prose. Worth remembering: the Sustainability Report’s p. 36 paragraph was not enough to reason about the mechanism, and the gate should have fetched this document before the concept page asserted one.⟩
