ISO Assurance Routes

Supporting standards, correctly scoped

External standards help an assurance team read the evidence. The Buktika Tika Standard governs the claim.

The governing relationship

Tika governs. ISO supports.

The Tika Standard governs Buktika claims. Where appropriate, it is designed to be read alongside relevant international standards. This page explains how specific ISO standards relate to different Buktika evidence and assurance pathways.

Important: Listing a standard does not mean that the Tika Standard or Buktika is certified, registered, or accredited under it. No single ISO standard governs all Tika work, and a reference does not convert a Buktika claim into a carbon credit, biodiversity credit, statutory offset, or additional-gain assertion.

Route map

Different claims invoke different standards

Field and laboratory evidence

Used where a lane relies on measured soil, vegetation, or related field readings.

  • ISO 18400 series — soil sampling
  • ISO/IEC 17025 — competence of testing and calibration laboratories
  • Relevant ISO soil-quality methods where a specific measurement requires them

Spatial evidence and data quality

Used for polygon identification, remote evidence, metadata, and geospatial record quality.

  • ISO 19115 — geographic metadata
  • ISO 19157 — geographic data quality
  • ISO/TS 19159-1 — optical remote-sensing calibration and validation

Validation and verification

Used where a lane makes greenhouse-gas or other quantified assertions, principally in Eco Restoration. Eco Conservation condition claims do not depend on these standards.

  • ISO 14064-2 and ISO 14064-3 — project quantification, monitoring, validation, and verification
  • ISO 14065 — bodies validating and verifying environmental information
  • ISO/IEC 17029 — validation and verification bodies

Management and governance

Read as organisational control routes for Buktika as methodology owner.

  • ISO 9001 — quality management
  • ISO 14001 — environmental management
  • ISO 45001 — occupational health and safety
  • ISO 37301 — compliance management

Traceability and evidence integrity

Used for chain of custody, record security, and the privacy of personal and farm data.

  • ISO 22095 — chain of custody
  • ISO/IEC 27001 — information security management
  • ISO/IEC 27701 — privacy information management

Funding-source disclosure context

These standards govern a Funding Source's own reporting and finance. The Tika Standard neither operates nor certifies under them.

  • ISO 14097 — investment and financing activities related to climate change
  • ISO 14030 series — green debt instruments
Lane application

How the routes meet the four Tika lanes

Eco Conservation

Condition, non-regression, consent, boundary, spatial evidence, and refresh discipline. It does not inherit greenhouse-gas verification standards unless it separately makes a greenhouse-gas assertion.

Eco Restoration

Restoration evidence and technical acceptance, with ISO 14064-2/3 and related validation routes invoked only where greenhouse-gas assertions are made.

MDX Human Restoration

Consent, safeguarding, privacy, grievance, payroll or service records, and relevant quality and compliance controls.

EDU Education

Curriculum, attendance, assessment, trainer credentials, child-safety controls where relevant, and accreditation only where a formal qualification claim is made.

Assurance posture

Auditor-readable without overclaiming

The Tika Standard is designed as an auditor-readable umbrella standard, with each claim type routed to the correct evidence and assurance basis. It is designed to be independently reviewable and capable of accredited validation or verification where the claim type and accreditation scope allow.

The full, role-classified standards register is published in BKT 17010:2026 Section 19.6.
