Why QAL Certification Matters

As environmental norms tighten globally and CPCB regulations get more rigorous in India, industries cannot afford inaccuracies in their emission data. Continuous Emission Monitoring Systems (CEMS) have become the industry standard for real-time pollutant tracking, but this data only holds legal weight when it’s QAL certified.

What is QAL?

QAL (Quality Assurance Level) is a regulatory benchmark defined under EN 14181, a European standard that governs the quality assurance of automated measurement systems used to assess emissions from industrial installations. It ensures:

  • Accurate pollutant measurements
  • Site-specific calibration accuracy
  • Ongoing reliability of your CEMS setup

EN 14181 was published by the European Committee for Standardization (CEN).

The History of QAL

The concept of QAL is driven by the need for high-quality, comparable emission data across EU nations.

  • First Global Adopter: Germany was the first country to implement QAL principles systematically, leveraging institutions like TÜV NORD and MCERTS for certification.
  • First in India: Among Indian companies, NTPC (National Thermal Power Corporation) was one of the earliest adopters of QAL-certified CEMS, driven by stricter emissions mandates and its commitment to ESG goals.

Breaking Down the QAL Levels

Here’s a simple distinction between QAL1, QAL2, and QAL3:

Without QAL? Big Risks.

  • Regulatory penalties from CPCB.
  • Inaccurate emission reporting leading to legal issues like Plant Shutdown
  • Failure to qualify for ESG benchmarks
  • Loss of green certifications & carbon monetization

Industries Where QAL is Critical

CPCB has categorized Industries into 17 categories, including below:

  • Power Plants
  • Cement & Steel
  • Refineries
  • Chemical Manufacturing
  • Waste-to-Energy Facilities
  • Environmental Audits & Reporting
