Pollution Prevention and Environmental Performance

Domain 7 tests whether you can distinguish real pollution prevention from end-of-pipe treatment, and whether you test performance improvement rather than promises.

Core rules

  • The hierarchy runs source reduction, then reuse, recycling and recovery, treatment, and disposal last.
  • ISO 14001 5.2 commits top management to protecting the environment, including preventing pollution; 6.1.2 and 8.1 turn that commitment into controls, and 9.1.1 requires monitored, evaluated environmental performance.
  • Recycling is not prevention. Sending a solvent to a reclaim still leaves the solvent in the process.
  • Under the EU Industrial Emissions Directive, BAT conclusions set the reference; in the US, permit limits and New Source Review shape the available options.
  • Useful performance metrics: energy and water per unit of output, waste per unit, VOC mass emitted, hazardous waste generated, non-compliance events.

Worked example

A coating line emits 40 tonnes of VOC per year. Option A is a thermal oxidizer with 98% destruction and high fuel cost. Option B is a switch to water-based coating, an 80% reduction at source with lower solvent purchase cost. Option B ranks higher in the hierarchy and usually in lifecycle cost, but it may affect product performance and needs validation. The auditor checks that options were evaluated, that the selected change is implemented, and that 9.1.1 indicators actually show the reduction - not merely that a project was announced.

Traps that cost marks

  • Labelling an oxidizer, scrubber, or landfill as pollution prevention.
  • Counting recycling as source reduction.
  • Ignoring energy and water while chasing visible waste streams.
  • Accepting a claimed reduction with no baseline or normalizing denominator.
  • Overlooking shifted impacts, such as higher energy use or a new waste stream created by the substitute.
