ENERGY STAR Details
What It Is
ENERGY STAR is the U.S. EPA's voluntary labeling and benchmarking program for superior energy efficiency. It sets category-specific performance thresholds above federal minimums using standardized DOE test procedures, covering products, homes, commercial buildings, and industrial plants.
Key Components
- Performance thresholds (e.g., 15% above standards for appliances)
- Third-party certification via EPA-recognized labs and bodies
- Ongoing verification testing (5-20% annually)
- Portfolio Manager for building scores (75+ for certification)
- Brand governance with strict mark usage rules
Why Organizations Use It
Reduces energy costs ($500B saved since 1992), emissions (4B tons avoided), unlocks rebates/procurement advantages, enhances reputation (90% consumer recognition), and supports ESG goals. Voluntary yet de facto standard in many markets.
Implementation Overview
Phased approach: assess gaps, test/certify products or benchmark buildings, deploy with labeling compliance, maintain via verification. Applies to manufacturers, builders, owners across U.S./Canada; requires partnership agreement, annual reporting.
ISO 27018 Details
What It Is
ISO/IEC 27018:2025 is a code of practice that extends 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. It addresses cloud challenges like multi-tenancy and cross-border data flows using a risk-based approach within an Information Security Management System (ISMS).
Key Components
- ~25–30 additional privacy-specific controls layered on ISO 27001 Annex A
- Core principles: consent/choice, purpose limitation, data minimization, accuracy, transparency, accountability
- Assessed during ISO 27001 audits; no standalone certification
Why Organizations Use It
- Builds customer trust, accelerates procurement via Statement of Applicability
- Aligns with GDPR Article 28, HIPAA processor obligations
- Mitigates risks, improves cyber insurance, enables market differentiation for CSPs
Implementation Overview
- Gap analysis, integrate controls into existing ISMS
- Update policies, contracts, subprocessors transparency
- Suited for CSPs all sizes; third-party audits tied to ISO 27001 certification
