CAA
U.S. federal law regulating air emissions nationwide
ISO 22000
International standard for food safety management systems
Quick Verdict
CAA mandates US air quality compliance through emissions standards and permits for all industries, while ISO 22000 is a voluntary global FSMS certification for food chain organizations. Companies adopt CAA to avoid penalties; ISO 22000 for market access and trust.

CAA Details
What It Is
The Clean Air Act (CAA), codified at 42 U.S.C. §7401 et seq., is a U.S. federal statute establishing the national framework for air quality protection. It regulates emissions from stationary and mobile sources through cooperative federalism, where EPA sets ambient and technology-based standards, and states implement via enforceable plans and permits. Core approach combines health-based NAAQS with source-specific controls.
Key Components
- NAAQS for six criteria pollutants (primary/secondary standards).
- SIPs for attainment planning and infrastructure.
- Technology standards: NSPS, MACT/NESHAPs for stationary sources; Title II for mobiles.
- Title V operating permits consolidating requirements.
- Enforcement via penalties, sanctions, citizen suits; market-based Title IV-A trading. Compliance is mandatory for emitters, with EPA oversight.
Why Organizations Use It
Drives legal compliance to avoid multimillion penalties, enforcement actions. Mitigates nonattainment risks affecting operations/expansion. Enhances ESG via emission reductions; enables strategic permitting. Builds stakeholder trust through transparent reporting.
Implementation Overview
Phased: gap analysis, emissions inventory, permitting (Title V/NSR), install CEMS/controls, training. Applies to major sources/industries nationwide; varies by state SIPs. No central certification; audited via permits/SIPs.
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 hazard control and compliance. Its risk-based approach integrates HACCP principles with management system discipline using the High-Level Structure (HLS) and dual PDCA cycles.
Key Components
- **Clauses 4-10Context, leadership, planning, support, operation, evaluation, improvement.
- Core elements: PRPs, hazard analysis, CCPs/OPRPs, traceability, communication.
- Built on Codex HACCP and HLS for integration.
- Voluntary certification via accredited bodies.
Why Organizations Use It
- Meets regulatory/customer requirements; reduces risks like recalls.
- Enhances market access, supplier qualification, efficiency.
- Builds trust with stakeholders; supports GFSI schemes like FSSC 22000.
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. (178 words)
