RoHS
EU regulation restricting hazardous substances in electrical equipment
ISO 50001
International standard for energy management systems
Quick Verdict
RoHS restricts hazardous substances in EEE for EU market access, while ISO 50001 provides a voluntary framework for systematic energy performance improvement. Companies adopt RoHS for compliance and sales, ISO 50001 for cost savings and sustainability.
RoHS
Directive 2011/65/EU (RoHS 2)
Key Features
- Homogeneous material thresholds limit 10 hazardous substances to 0.1%
- Open-scope applies to all EEE unless explicitly excluded
- Time-limited exemptions managed via delegated directives
- Requires technical documentation and EU Declaration of Conformity
- Tiered verification using IEC 62321 testing standards
ISO 50001
ISO 50001:2018 Energy management systems
Key Features
- Demonstrable continual energy performance improvement via EnPIs/EnBs
- Annex SL structure enables integration with ISO 9001/14001
- Energy review identifies SEUs and improvement opportunities
- Mandatory energy data collection and monitoring plan
- Top management accountability and leadership requirements

RoHS Details
What It Is
Directive 2011/65/EU (RoHS 2) is an EU regulation restricting hazardous substances in electrical and electronic equipment (EEE). It protects human health and the environment by minimizing risks from EEE waste management, complementing the WEEE Directive. Scope is open: all EEE unless excluded. Core approach applies maximum concentration values (MCVs) to homogeneous materials.
Key Components
- 10 restricted substances: Pb, Cd, Hg, Cr(VI), PBB, PBDE, DEHP, BBP, DBP, DIBP.
- Thresholds: 0.1% by weight (Cd at 0.01%).
- Annex III/IV time-limited exemptions.
- Compliance model: self-declaration via EU Declaration of Conformity (DoC) and technical files per EN IEC 63000; CE marking where applicable.
Why Organizations Use It
- Mandatory for EU/EEA market access; non-compliance risks fines, recalls.
- Manages supply chain risks, enables recyclability.
- Ensures level playing field, supports ESG and circular economy.
- Builds stakeholder trust, avoids enforcement by Member States.
Implementation Overview
- Risk-based: supplier declarations, BoM analysis, IEC 62321 tiered testing (XRF screening, ICP-MS/GC-MS confirmation).
- Key activities: scoping, exemption tracking, technical files (10-year retention).
- Applies to manufacturers/importers of EEE; scales by portfolio complexity.
ISO 50001 Details
What It Is
ISO 50001:2018 is the international standard specifying requirements for Energy Management Systems (EnMS). It enables organizations to systematically improve energy performance—efficiency, use, and consumption—using the Plan-Do-Check-Act (PDCA) cycle and Annex SL high-level structure.
Key Components
- Clauses 4–10: context, leadership, planning (energy review, SEUs, EnPIs, EnBs), support, operation, evaluation, improvement.
- Formal energy data collection plan, monitoring, internal audits, management review.
- Built on continual improvement; certification optional via ISO 50003-accredited bodies.
Why Organizations Use It
- Achieve 4–20% energy/cost savings, GHG reductions.
- Meet regulatory expectations (e.g., EU EED), enhance ESG reporting.
- Mitigate supply risks, build resilience.
- Gain procurement advantages, stakeholder trust.
Implementation Overview
Phased approach: gap analysis, energy review, metering deployment, controls, audits. Scalable for all sizes/sectors; requires data infrastructure, training. Certification involves Stage 1/2 audits, surveillance.
Key Differences
| Aspect | RoHS | ISO 50001 |
|---|---|---|
| Scope | Hazardous substances in EEE materials | Energy management systems and performance |
| Industry | EEE manufacturers, global with regional variations | All sectors worldwide, any energy user |
| Nature | Mandatory EU directive for market access | Voluntary certification standard |
| Testing | XRF screening, lab analysis of materials | EnPI monitoring, internal audits, reviews |
| Penalties | Fines, recalls, market bans by Member States | No legal penalties, loss of certification |
