What is the primary objective of **ISO 14064**?

**ISO 14064 provides requirements and guidance for quantifying, reporting, and verifying greenhouse gas (GHG) emissions and removals.** The standard family comprises three parts: **ISO 14064-1:2018** for organizational-level inventories, **ISO 14064-2:2019** for project-level reductions/removals, and **ISO 14064-3:2019** for validation/verification. It enforces five principles—**relevance, completeness, consistency, transparency, accuracy**—to ensure credible, comparable GHG statements supporting regulatory reporting, investor disclosure, and carbon markets.

Who is legally or professionally required to comply with **ISO 14064**?

**No organizations are legally required to comply with ISO 14064, as it is a voluntary international standard.** It is professionally adopted by companies, governments, NGOs, and project developers needing credible GHG inventories for stakeholder demands, emissions trading, green finance, or procurement. Entities in regulated regimes (e.g., EU ETS, California SB-253) often use it for methodological rigor, especially where verified Scopes 1-3 data is expected.

Does **ISO 14064** require an external audit or third-party certification?

**ISO 14064 does not require external audit or third-party certification.** Parts 1 and 2 encourage but do not mandate independent validation/verification under **ISO 14064-3**, which specifies risk-based assurance (limited or reasonable levels). In practice, third-party verification by **ISO 14065**-compliant bodies enhances credibility for markets, regulators, and investors, evaluating boundaries, data quality, and principles conformity.

How often should an assessment for **ISO 14064** be performed?

**ISO 14064 assessments should be performed annually to maintain consistency and track performance against a selected base year.** Organizational inventories (Part 1) cover a defined reporting period, typically calendar or fiscal year, with base-year recalculations for significant structural changes (e.g., acquisitions). Project monitoring (Part 2) follows defined plans, while verification (Part 3) aligns with reporting cycles or stakeholder needs.

What are the consequences of non-compliance with **ISO 14064**?

**Non-compliance with ISO 14064 carries no direct penalties, as it is voluntary.** Indirect risks include rejected GHG claims in carbon markets, failed procurement qualifications, investor skepticism, or regulatory scrutiny in disclosure regimes expecting verifiable data. Poor inventories may lead to greenwashing accusations, restated reports, or lost access to climate finance due to unverifiable Scopes 1-3 emissions.

Can **ISO 14064** be mapped to other international frameworks?

**Yes, ISO 14064 aligns closely with the GHG Protocol Corporate Standard's principles and Scope classifications.** Its five principles mirror GHG Protocol requirements, enabling interoperable inventories. Part 1 supports organizational reporting; Part 2 complements project protocols; Part 3 facilitates assurance compatible with frameworks like CDP or SBTi, without prescribing cross-standard mappings.

What is the first step to begin implementing **ISO 14064**?

**The first step is defining organizational and operational boundaries per ISO 14064-1.** Select consolidation approach (**equity share, operational, or financial control**), identify emission sources/sinks across Scopes 1-3, and document relevance to ensure completeness. This executive governance decision sets the inventory scope, base year, and data needs for subsequent quantification and assurance.

What is the primary objective of **ISO 27017**?

**ISO 27017 provides cloud-specific implementation guidance for 37 ISO 27002 controls plus 7 additional cloud-focused controls (CLD.6.3.1, CLD.8.1.5, CLD.9.5.1, CLD.9.5.2, CLD.12.1.5, CLD.12.4.5, CLD.13.1.4).** Published in 2015, it addresses shared responsibilities between **cloud service providers (CSPs)** and **cloud service customers (CSCs)**, covering multi-tenancy segregation, virtual machine hardening, asset removal/return, administrative operations security, customer monitoring, and virtual network alignment.

Who is legally or professionally required to comply with **ISO 27017**?

**No organization is legally required to comply with ISO 27017, as it is a voluntary code of practice.** It is professionally recommended for **CSPs** and **CSCs** managing cloud risks in public, private, or hybrid environments across IaaS, PaaS, and SaaS models, particularly to demonstrate due diligence in procurement, regulatory audits, or customer contracts.

Does **ISO 27017** require an external audit or third-party certification?

**ISO 27017 does not support standalone third-party certification or require external audits.** Controls are implemented and assessed within an **ISO 27001** ISMS audit, where certification bodies evaluate cloud-specific guidance as an extension in the Statement of Applicability (SoA).

How often should an assessment for **ISO 27017** be performed?

**ISO 27017 assessments occur as part of annual ISO 27001 surveillance audits and triennial recertification.** Cloud controls must be continuously monitored via risk assessments, with re-evaluations triggered by significant changes like new services or incidents.

What are the consequences of non-compliance with **ISO 27017**?

**Non-compliance with ISO 27017 carries no direct legal penalties, as it is not mandatory.** Indirect risks include failed procurement RFPs, regulatory scrutiny for inadequate cloud risk management, audit nonconformities in ISO 27001 certifications, and heightened breach exposure from unaddressed multi-tenancy or shared responsibility gaps.

Can **ISO 27017** be mapped to other international frameworks?

**Yes, ISO 27017 controls map directly to ISO 27001/27002 Annex A domains and extend 37 ISO 27002 controls with cloud guidance.** The 7 CLD controls align with cloud risks in frameworks like NIST SP 800-53 via shared responsibility matrices, enabling unified ISMS coverage without duplicative efforts.

What is the first step to begin implementing **ISO 27017**?

**Conduct a cloud-specific risk assessment within your ISO 27001 ISMS to identify applicable controls.** Define scope for cloud services, document shared responsibilities (starting with CLD.6.3.1), and update the Statement of Applicability to include the 37 guided controls and 7 CLD additions.
