ISO 14064 Details
What It Is
ISO 14064 (Parts 1-3:2018/2019) is an international standard family for greenhouse gas (GHG) quantification, reporting, and assurance. It provides modular requirements for organizational inventories, project reductions/removals, and validation/verification using a principles-based approach emphasizing transparency and accuracy.
Key Components
- **Part 1Organizational GHG inventories covering Scopes 1-3 emissions/removals.
- **Part 2Project-level accounting with baselines, additionality, monitoring.
- **Part 3Risk-based validation/verification processes.
- Five core principles: relevance, completeness, consistency, transparency, accuracy.
- Third-party assurance statements (limited/reasonable levels), no formal certification.
Why Organizations Use It
- Enables regulatory compliance (e.g., CSRD, SB-253) and carbon market participation.
- Builds stakeholder trust via verifiable claims, mitigating greenwashing risks.
- Drives strategic insights for decarbonization, supply-chain management.
- Enhances investor confidence and competitive differentiation.
Implementation Overview
- Phased approach: governance, boundary-setting, data collection, reporting, verification.
- Suited for all organization sizes, especially complex supply chains/industries.
- Cross-functional teams; 6-12 months typical; requires data systems, training.
ISO 27018 Details
What It Is
ISO/IEC 27018 is an international code of practice extending ISO/IEC 27001 and ISO/IEC 27002 specifically for protecting personally identifiable information (PII) processed by public cloud service providers (CSPs) acting as PII processors. Published in editions from 2014, revised 2019 and 2025, its scope targets public cloud environments with multi-tenancy and cross-border risks. It uses a risk-based approach, adding ~25-30 privacy-specific controls to the general security framework.
Key Components
Key pillars include transparency, accountability, data minimization, and security safeguards across organizational, people, physical, and technological domains. Built on principles like consent, purpose limitation, accuracy, and breach notification, it integrates into ISO 27001's Information Security Management System (ISMS). Compliance is assessed during ISO 27001 audits via Statement of Applicability, without standalone certification.
Why Organizations Use It
CSPs leverage it for market differentiation, faster procurement, regulatory alignment (e.g., GDPR Article 28, HIPAA), reduced cyber insurance friction, and enhanced customer trust. It clarifies processor responsibilities, supports data subject rights, and minimizes legal risks.
Implementation Overview
Start with gap analysis against existing ISMS, integrate controls, update policies/contracts. Applicable to CSPs of all sizes globally; requires ISO 27001 prerequisite. Audits by accredited bodies involve documentation review and effectiveness testing, with annual surveillance. (178 words)
