ENERGY STAR
U.S. voluntary program for energy-efficient products and buildings
ISO 22000
International standard for food safety management systems.
Quick Verdict
ENERGY STAR drives energy efficiency certification for products and buildings via third-party testing, while ISO 22000 ensures food safety through HACCP-integrated management systems. Companies adopt ENERGY STAR for cost savings and market edge; ISO 22000 for supply chain trust and compliance.

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 minimums for appliances, 75+ score for buildings)
- Third-party certification via EPA-recognized labs and bodies
- Post-market verification testing (5-20% annually)
- Portfolio Manager for benchmarking
- Strict brand governance with controlled marks Certification requires ongoing compliance and annual renewal for buildings.
Why Organizations Use It
Reduces energy costs ($500B saved since 1992), emissions (4B tons avoided), unlocks rebates/procurement advantages, enhances reputation (90% consumer recognition), supports ESG goals and regulatory benchmarking.
Implementation Overview
Phased approach: assess/gap analysis, design/testing/certification, deployment/marketing, ongoing verification. Applies to manufacturers, builders, building owners across sizes/industries, primarily U.S./Canada. Demands data governance, training, and continuous improvement.
ISO 22000 Details
What It Is
ISO 22000:2018 is the international standard for Food Safety Management Systems (FSMS). It provides a certifiable framework for organizations in the food chain to ensure safe products through systematic hazard control. Its risk-based approach integrates HACCP principles with management system discipline using the High-Level Structure (HLS).
Key Components
- **Clauses 4-10Context, leadership, planning, support, operation, evaluation, improvement.
- **Core elementsPRPs, hazard analysis, CCPs/OPRPs, traceability, communication, validation/verification.
- Built on Codex HACCP and two PDCA cycles (organizational and operational).
- Voluntary certification via accredited bodies.
Why Organizations Use It
- Meets regulatory/customer requirements; reduces recalls and risks.
- Enhances supply chain trust, market access (e.g., GFSI schemes).
- Drives efficiency, integration with ISO 9001/14001; builds resilience.
Implementation Overview
- Phased: gap analysis, PRPs/hazard plans, training, audits.
- Applies to all food chain organizations; scalable by size.
- Certification: stage 1/2 audits, annual surveillance.
