CERTIFICATION-READY CARBON ACCOUNTING, ESG AND ISO
Carbon Accounting Certification Services for ESG, ISO and Carbon Credits
Carbon accounting certification services are most valuable when the data, evidence and claims are built before the auditor arrives. At Zero Emissions Hub we help organizations prepare certification-ready GHG inventories, ESG disclosures, ISO documentation, circular economy metrics and carbon credit files for independent verification, assurance and certification.
Our Specialized Certification Readiness Services
ISO 14064-1 – Carbon Accounting Certification & GHG Inventory Readiness
We help you define organizational and reporting boundaries, structure GHG inventory categories, select emission factors and build calculation files, procedures and evidence trails that support ISO 14064-1 verification, GHG Protocol reporting, CSRD readiness, investor requests and customer due diligence.
ESG Certification and Sustainability Assurance Preparation
We organize ESG information into an assurance-ready structure: topic ownership, evidence registers, KPI definitions, control checks, calculation logic and disclosure narratives that make sustainability claims easier to review, explain and defend during external assurance or certification work.
ISO 14067 – Product Carbon Footprint Certification Support
We prepare product carbon footprint studies for certification by defining functional or declared units, system boundaries, life cycle stages, supplier data rules, allocation choices and evidence packs aligned with ISO 14067, ISO 14040, ISO 14044 and product-level climate claims.
ISO 59020 – Circular Economy Certification and Circularity Measurement
We turn circular economy ambitions into measurable certification evidence by defining the system in focus, selecting circularity indicators, documenting data sources and preparing ISO 59020-aligned assessments that connect resource inflows, outflows, retained value and circular performance.
Carbon Credits Validation, Verification and Registry Evidence
For carbon credit projects, we support the documentation expected by validation and verification bodies: project description files, baseline logic, additionality evidence, monitoring plans, ownership records, data controls and registry-ready supporting documents for credible carbon reduction or removal claims.
ISO 14068-1 – Carbon Neutrality Claim and Offset Documentation
We prepare organizations and product teams for carbon neutrality claims by linking footprint quantification, reduction plans, residual emissions, offset selection, retirement evidence and transparent claim wording in line with ISO 14068-1 and recognised verification expectations.
