Greenhouse Gases

Organisation-level quantification and reporting

View at ISO.orgGap Analysis

ISO 14064-1:2018 specifies principles and requirements for designing, developing, managing and reporting an organisation-level greenhouse gas inventory. It covers organisational and reporting boundaries, the selection of a base year, quantification methods, information quality and GHG reporting. This page addresses Part 1 of the ISO 14064 family, not project-level accounting or independent verification.

Key Requirements

  • 1
    Set organisational boundaries using an explained consolidation approach
  • 2
    Define reporting boundaries and significant direct and indirect categories
  • 3
    Document activity data, emission factors, methods and assumptions
  • 4
    Establish and recalculate a base year when relevant changes are significant
  • 5
    Assess uncertainty, manage data quality and retain reproducible records
  • 6
    Report boundaries, exclusions, methods, results and changes transparently

Key Benefits

  • A structured organisation-level GHG inventory
  • Clearer reporting boundaries and category decisions
  • Better data quality and reproducibility
  • Transparent treatment of base-year changes
  • A sound basis for separate validation or verification
