Carbon Credit Offset Verification Bodies: 45 Validation/Verification Bodies from 6 Official Registers (JCM, NABCB, DAkkS, J-Credit, UK Peatland and Woodland Carbon Codes)
45 organisations that at least one of six official registers lists for validating or verifying greenhouse-gas reduction or removal projects (carbon offsets), one row per organisation, read on 2026-10-12. Rows per register: JCM TPE 24, NABCB ISO 14065 project level 10, DAkkS ISO 14064-2 project level 12, J-Credit 4, Peatland Code 1, Woodland Carbon Code 2; 8 organisations are in two or more. Each row gives the registers' own details: JCM Third-Party Entity numbers, host countries and sectoral scopes (177 active designations), NABCB and DAkkS accreditation numbers with validity dates and the project-level scope wording (10 rows whose NABCB scope names Verra VCS), J-Credit methodology categories, and what the UK Peatland and Woodland Carbon Codes state. Most stated addresses are in India (15 rows) and Germany (12 rows); US-based verifiers appear only through the JCM table (1 row with a United States address). Not a complete list of carbon-credit verifiers: the Verra, Gold Standard, ACR, ART and ICAO CORSIA lists are not used because their terms forbid commercial reuse, CARB's offset verification body list is not used because its conditions of use ask other websites not to lift its information, and Climate Action Reserve and UNFCCC (CDM) blocked automated access.

Where the source data is published
All six registers are free to read: jcm.go.jp (Third Party Entity list), nabcb.qci.org.in (validation and verification bodies), dakks.de (accredited bodies search and accreditation PDFs), japancredit.go.jp (審査機関), iucn-uk-peatlandprogramme.org and woodlandcarboncode.org.uk. URLs are in every row. ReqoData's work is reading them all on 2026-10-12, matching the same legal entity across registers, reading the 61 DAkkS register documents (34 accreditation annexes and 27 certificates of 33 bodies) and 13 NABCB scope pages to keep only project-level verifiers, and keeping the exact register wording beside each row.

Source data as of
NABCB accreditation records with their stated validity dates; DAkkS accreditation annexes with their stated validity dates; JCM Third Party Entity table, J-Credit 審査機関一覧, Peatland Code and Woodland Carbon Code pages (no list date shown); all read on 2026-10-12
Last verified is the date we fetched the source data and confirmed it was the latest version the publishers had released.
What this list adds to the free source data
- Six official registers that are normally checked one by one are joined into one row per organisation: the JCM Third-Party Entity table (177 active designations, every one quoted), NABCB's and DAkkS's ISO 14065 accreditation records, the J-Credit Scheme's registered verification bodies and the Peatland and Woodland Carbon Code pages. 8 organisations are matched across two or more registers (same legal entity only; group companies in different countries, such as TÜV SÜD South Asia and TÜV SÜD Industrie Service, stay separate rows).
- Accreditation-body records are filtered to project-level work with one rule: a body becomes a row only if its own published scope contains a project-level ISO 14064-2 area. NABCB: 13 GHG validation/verification body scope pages read, 10 list ISO 14064-2. DAkkS: the register's 61 active validation/verification entries are 27 accreditation certificates (cover sheets) and 34 annexes of 33 bodies; a certificate and its annex are one accreditation, the scope is read from the annex (the German, definitive version where DAkkS publishes one), and 12 bodies have the area 'auf Projektebene gemäß DIN EN ISO 14064-2:2020'. Every other body read is listed once in meta.excluded_candidates with that reason (its annex or scope page has no ISO 14064-2 project-level area), except Nippon Kaiji Kyokai General Incorporated Foundation (一般財団法人日本海事協会), which is a row through another register and whose accreditation cell says it has no project-level area.
- The JCM table's own marks are kept as counts per organisation (ISO 14065 accreditation, DOE of the CDM, DOE of the Article 6.4 mechanism): 12 rows have at least one designation marked 1 as a CDM DOE and 1 row has at least one marked 1 as an Article 6.4 DOE. NABCB scope pages name Verra VCS for 10 rows and Gold Standard for 1 row; NABCB's CORSIA line (1 row) is labelled as aviation emission monitoring report verification, not offset verification.
- Contact persons, e-mail addresses and phone numbers printed by the registers are left out on purpose; e-mail remarks are cut from addresses.
- Every row carries the register wording it relies on (evidence_quote); the build script re-fetches every source, re-checks every quote and the terms wording, and refuses to write the file if any check fails.
Limitations and what's not included
- Not a complete list of carbon-credit verifiers. Verra (VCS), Gold Standard, ACR, ART, Puro.earth, Isometric, Cercarbono, BioCarbon and ICAO (CORSIA) publish VVB lists, but their website terms forbid commercial reuse, copying, crawling or derivative works, so they are not used. The California Air Resources Board (CARB) publishes its accredited offset verification bodies, but its Conditions of Use ask other websites not to lift its information and not to attribute lifted information to CARB, so that list is not used either; verifiers accredited only by CARB are missing. Climate Action Reserve, UNFCCC (CDM and Article 6.4 DOE lists), ANAB, UKAS and SCC answered automated requests with HTTP 403 or a bot challenge. GCC, ONAC (Colombia), JAB (Japan), TAF (Taiwan), T-VER (Thailand) and CNCA (China CCER) show their lists only through JavaScript. Verifiers that appear only in those lists are missing.
- A row means a register used here lists the organisation; it does not mean approval by Verra, Gold Standard or any programme not named in the row. 'Verra VCS', 'Gold Standard' and 'GCC' in nabcb_accreditation are ISO 14065 accreditation scopes granted by NABCB, not approvals by those programmes. 'CORSIA emission monitoring report verification (aviation emissions, not offset verification)' (NABCB) and the DAkkS CORSIA area (verification of aeroplane operators' emission and cancellation reports) are not approvals to verify offset projects. DAkkS and NABCB accreditation covers the stated scope only.
- JCM table marks are counts of the value 1; the JCM page does not explain other values (such as 2), so they are counted but not interpreted. JCM sectoral scope numbers follow the JCM's own numbering, and the JCM rows of one organisation can differ by host country.
- Registers are as of their own dates: NABCB gives validity dates per body and DAkkS per accreditation annex (some annexes state a start date only); the JCM table, J-Credit list and UK code pages carry no list date, so they are as read on 2026-10-12. Suspended and withdrawn JCM designations are named but not counted.
- JCM 'until' dates in jcm_sectoral_scopes are copied as the JCM table writes them and can already be past on the read date; a designation still counts as active when it is not marked suspended or withdrawn. On 2026-10-12, 1 of the 177 counted designations has an 'until' date before that day: AENOR CONFÍA, S.A.U. TPE-CL-010 (Chile): validation and verification scopes 2, 4, 6 until 22 Apr 26.
- Country is given only where the stated address names it (39 of 45 rows). Websites are read from NABCB only (10 rows).
- Organisation data only: no people's names or contact details. Delivered as CSV; no API.

Columns in the CSV (16)
| Column | Description |
|---|---|
| organisation_name | Organisation as a register names it (one row per legal entity). Where one register names it in English and another in Japanese, both names are given; other spellings appear in the quotes. |
| address_stated | One office address exactly as a register states it (e-mail remarks and second offices cut off). 'not stated in sources used' if no register gives one. |
| country_stated | Country only where the stated address itself names it; 'not stated in sources used' otherwise (never inferred from a city, state or postcode). |
| website_stated | Website exactly as NABCB states it; 'not stated in sources used' otherwise (websites are read from NABCB only). |
| registers_listed | Registers used here that list the organisation for project-level validation/verification, separated by ' | ': JCM TPE, NABCB ISO 14065 project level, DAkkS ISO 14064-2 project level, J-Credit, Peatland Code, Woodland Carbon Code. |
| registers_count | Number of those registers (1-6). |
| jcm_tpe_designations | Active JCM Third-Party Entity designations (active here means the designation's 'Suspended / Withdrawn' cell in the JCM table is empty; the table has no 'active' status of its own) as 'host country (TPE number, designated DD Mon YY)', newest first, separated by ' | '; suspended or withdrawn designations are named after 'not counted:'. 'not listed' if none. |
| jcm_sectoral_scopes | JCM sectoral scope numbers for validation and for verification exactly as the JCM table states them (with the table's 'until' dates); distinct strings across active designations separated by ' | '. |
| jcm_table_marks | How many active JCM designations carry the value 1 in the table columns 'Accredited under ISO 14065', 'DOE of the CDM' and 'DOE of the Article 6.4 Mechanism'. Other values (such as 2) are not explained on the JCM page; they are counted, not interpreted. |
| nabcb_accreditation | NABCB ISO 14065 accreditation: certificate number, validity, the project-level ISO 14064-2 activity as written, and the offset-programme scheme scopes the page names (Verra VCS, Gold Standard, GCC). Where the page also lists CORSIA, it is shown separately as 'CORSIA emission monitoring report verification (aviation emissions, not offset verification)': NABCB's line is the verification of aeroplane operators' emission monitoring reports, not of offsets or credits. 'not listed' otherwise. |
| dakks_accreditation | DAkkS accreditation as one record per accreditation: the accreditation number (certificate '-00' and its annex '-01', ... are the same accreditation), the annex's 'valid since' date from the register and 'valid to' date from the annex, and whether the German (definitive) annex contains the project-level area under DIN EN ISO 14064-2:2020. 'not listed' otherwise. |
| j_credit_verification_body | J-Credit Scheme registered verification body (審査機関) with the methodology categories marked in its table (EN energy, IN industrial processes, AG agriculture, WA waste, FO forestry; provisional registrations flagged) and the corporate number (法人番号). 'not listed' otherwise. |
| uk_land_carbon_codes | What the Peatland Code and Woodland Carbon Code pages state about the organisation. 'not listed' otherwise. |
| source_url | Source URL(s) for the row, separated by ' | '. |
| evidence_quote | Exact wording relied on, each prefixed by the register name; several quotes separated by ' || '. Spreadsheet and table cells are given as 'column header: cell value' pairs joined with ' ; '. |
| last_verified | Date ReqoData re-fetched every source of the row and re-checked every quote. |
