A joint research laboratory of Hitachi, Ltd. and AIST (National Institute of Advanced Industrial Science and Technology, Japan’s largest public research institute, under METI). Its stated purpose is standards production, not research publication: Hitachi established it “working to create internationally accepted rules and standards originating from Japan” (Sustainability Report 2026, p. 36).
Its named output in the report is Circular Value-added Productivity (CVP), a circular-economy metric expressing the economic efficiency of circular investment.

The lab writes its own name as “H-AIST CE Lab.” in its publications;
“CECRL” is the form used on its web domain (unit.aist.go.jp/hitachi-cecrl)
and in Hitachi’s Sustainability Report. Same body.
Where its evidence comes from
The economic premise behind CVP is not the lab’s own fieldwork. Per the
June 2025 white paper: “In 2023,
The Lab. commissioned Yordas Group to conduct a global assessment of CE
practices, challenges, and opportunities, with a particular focus on
economic barriers to adoption.” That study produced the three findings the
indicator answers — upfront cost, unevenly distributed incentives,
and CE indicators lacking “granularity in financial metrics”. It is not
published and not listed in any reference list in sources/.
⟨Background: Yordas Group is a UK regulatory-compliance and sustainability consultancy.⟩
⟨Inference: the framing of the problem — economic barriers first, data and confidentiality barriers nowhere — was fixed by a commissioned scope in 2023, before the metric existed. That is worth knowing in a conversation where SINE’s contribution is precisely the barrier the scope did not include.⟩
Named people
From the study-group roster in the CE Association white paper ⟨corrected 2026-10-29: this read “the same white paper”, which the preceding section ties to the June 2025 overview; none of these names appear in that document⟩ — the people doing this work, on the lab’s two sides:
- Hitachi: Osamu Hoshino, Takahiro Kihara, Yuki Murasato (+ Yoshiyuki Ichihashi as observer).
- AIST: Toru Den, Koshi Kamigaki. AIST Solutions Co. (an AIST subsidiary): Ken-ichi Miyamoto, Akira Nakabayashi.
Hoshino, Murasato, Den and Nakabayashi are also the four authors of the EcoDesign 2025 CVP paper — so the lab’s output and its seat in the Circular Economy Association study group are carried by the same people.
The standards route it is aiming at
Per the CE Association white paper (and not stated in the Sustainability Report) ⟨corrected 2026-10-29: this read “the white paper”, pointing by proximity at the June 2025 overview, which makes none of the ISO/WTO argument below — as its own page correctly records⟩:
- ISO — first as an annex to ISO/AWI 59011 (Circular economy — Organizing a value network towards circularity, under development), via ISO/TC 323 WG3; later possibly as a standalone indicator standard. Reason given: 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.”
- WBCSD — position CVP inside the Global Circularity Protocol alongside CMP and CTI Revenue, WBCSD being treated as a de facto standard-setting body. See WBCSD.
So the answer to the old open question below is: ISO/TC 323 WG3, via ISO/AWI 59011, at the annex-proposal stage. Not IEC — the IEC SMB seat belongs to the wider apparatus, not to this metric.
What the lab actually is: three research themes ⟨2026-10-16⟩
From the Third Open Forum report (July 2026), Director Katsumasa Miyazaki’s own overview. The lab runs three themes, not one:
- Grand design — an articulated “ideal future” for a CE society and a transition path to it; built from ~20,000 simulated scenarios reduced to nine types and three branching factors, with the chosen future explicitly “not technology-led”.
- Digital solutions — a life-cycle simulator (material flows, CO₂ and per-stakeholder economic value, with a user-behaviour module predicting collection rates; validated on Hitachi Industrial Equipment Systems screw compressors), plus three downstream technologies: image-based model identification where nameplates are unreadable (97% on automotive parts), a low-cost wireless sensor system for electricity and operating time, and per-unit process-level environmental data.
- Standardization strategy and policy recommendation — “both offensive and defensive rule-making … that strengthen the international competitiveness of Japanese companies”. The defensive half is absorbing European developments; the offensive half is Japanese-led standards.
CVP is one of two outputs of theme 3, not the lab’s programme. ⟨Correction 2026-10-16: this page previously described the lab as a metric producer with a standards pipeline attached. It is a three-theme research programme in which the metric is one of two “forms of value visualization” inside one theme.⟩
Also named: Deputy Director Keijiro Masui; presenters Masahide Ban (Hitachi) and Yoshiko Takenaka (AIST) on the roadmap, Ippei Kono and Yoshiyuki Furukawa (AIST) on digital solutions. Established 2022; the closing remarks date the forum at “40 months since the establishment”. Hitachi’s closing speaker announced a “renewed organizational structure” without detail.
The half of the proposal, now described ⟨updated 2026-10-16⟩
Found. The second half is residual-value grading — presented by Koshi Kamigaki at the Third Open Forum as “grading for the visualization of residual value”, built on a study of plastic-recycling operations, with quality and provenance information as its object and the IEC Common Data Dictionary as a named standardization target. The CVP literature never describes it because it belongs to the other work stream. The original text of this section follows, kept because the search it prompted is what produced the answer.
The half of the proposal nobody has described ⟨superseded⟩
The H-AIST proposal to the study group has two parts. One is CVP. The other is “data model standards for information on goods including quality information” — named in the white paper and then never explained in it. ⟨Inference: that is the layer closest to SINE’s work, and the one we know least about. Worth locating before the CVP layer is argued about.⟩ See open tasks.
Why a state-institute partner matters here
⟨Background: AIST sits under METI, so a Hitachi-AIST metric carries national-industrial-policy backing into ISO/IEC rather than arriving as a single vendor’s proposal. “Originating from Japan” in the report text is the explicit frame.⟩
⟨Inference: CECRL is best read as the research end of a standards pipeline whose other end is already built — see the apparatus below. A metric that leaves CECRL has a committee, a working-group structure and an IEC seat waiting for it. That is the part SINE cannot replicate and the reason to enter as a contributor rather than as an author of a competing metric.⟩
The apparatus it feeds
From the same page (p. 36):
- Hitachi Group Standardization Committee, established under the Chief Technology Officer. Head: the executive officer in charge of R&D (CTO). Members: CTO-level executives from each business unit and major Group company.
- Steering Committee — “identifies priority themes for Hitachi’s medium- to long-term activities”; members are international standardization promoters across BUs and Group corporate divisions.
- Rule-making Promotion Group, a Secretariat, a Liaison Committee, a Planning Working Group and numbered Priority Theme Working Groups.
- A Hitachi employee holds a seat on the IEC Standardization Management Board (SMB) — the upper-level committee supervising IEC’s standardization activities, fifteen members total across all IEC member countries.
- Hitachi employees also hold chair, secretary and other leadership posts in international bodies; two received honours from METI (Minister level and Director-General, Innovation and Environment Bureau) at the fiscal 2025 Industrial Standardization Awards.
- Standardization is embedded in internal talent development (lectures and practical training in technical-leader programmes) and in an internal recognition programme.
Hitachi’s own statement of why: international standardization is “one of the key means of establishing the international rules needed to achieve a sustainable society”, and providing solutions consistent with those standards “allows Hitachi to support the sound development of global markets”.
⟨Inference: the honest reading is that standards participation is a distribution channel as much as a public good — a metric Hitachi helped define is a metric Hitachi’s products are already instrumented for. Both readings are true at once and neither needs to be argued against.⟩
Open questions for Hitachi
- Does the CVP definition specify a data-provenance requirement for its
inputs, or does it assume the input data exists? ⟨Partly answered: the
white paper records that VN-wide disclosure of numerator and denominator
data “is difficult” and offers only trust-based remedies. The April 2026
research report, now in
sources/, is what settles the rest.⟩ Which IEC/ISO committee is the intended home for CVP— answered: ISO/TC 323 WG3, as an annex to ISO/AWI 59011.Is CECRL’s remit metrics only, or also the data infrastructure the metrics run on?— answered: both, and more. Three themes, of which standardization is one; within it, two halves, of which residual-value grading is the data layer.- Does the data-model half exist as a document anywhere, or only as
conference presentations? Nothing in
sources/carries a schema, a work item number, or a venue beyond the CDD mention. - What is CECRL’s relationship to AIST Solutions Co., which supplies two of the people and is a commercial subsidiary?
