ISO 50001 Details
What It Is
ISO 50001:2018 is an international certification standard for Energy Management Systems (EnMS). It provides a systematic framework to improve energy performance—efficiency, use, and consumption—across organizations of any size or sector. Built on the Plan-Do-Check-Act (PDCA) cycle and Annex SL High-Level Structure, it ensures continual improvement through data-driven processes.
Key Components
- Core elements: energy policy, review, Significant Energy Uses (SEUs), EnPIs, EnBs, data collection plans, operational controls.
- Clauses 4-10 align with ISO 9001/14001 for integrated systems.
- Emphasizes risk/opportunity assessment, leadership accountability, audits, and demonstrable performance improvement.
- Optional third-party certification via ISO 50003.
Why Organizations Use It
- Reduces energy costs (4-20% savings), enhances resilience, supports GHG reductions.
- Meets regulatory expectations (e.g., EU directives), boosts ESG credibility.
- Manages supply risks, improves procurement, gains competitive edges in tenders.
Implementation Overview
- Phased: gap analysis, energy review, action plans, monitoring, audits.
- Applicable globally, scalable for SMEs to multinationals.
- Involves metering investment, training, cross-functional teams; certification optional but audit-based.
ISO 22000 Details
What It Is
ISO 22000:2018 is the international standard for Food Safety Management Systems (FSMS). It provides a certifiable framework integrating HACCP principles with management system rigor using the High Level Structure (HLS). Its primary purpose is to enable organizations across the food chain to control hazards, ensure safe products, and meet regulatory/customer requirements through risk-based thinking and dual PDCA cycles.
Key Components
- 10 clauses following HLS: context, leadership, planning, support, operation, evaluation, improvement.
- Core elements: PRPs, OPRPs, CCPs, hazard analysis, traceability, communication, validation/verification.
- Built on Codex HACCP and Annex SL for integration with ISO 9001/14001.
- Voluntary certification via accredited bodies with staged audits.
Why Organizations Use It
- Drives market access, supplier qualification, regulatory compliance.
- Reduces recalls, COPQ, enhances resilience.
- Builds stakeholder trust, competitive edge via GFSI alignment.
Implementation Overview
- Phased: gap analysis, PRPs/HACCP development, training, audits.
- Scalable for SMEs to multinationals in food chain sectors globally.
- Requires 3+ months operation pre-certification; annual surveillance.
