Usage Guidance

  • The Greenhouse Gas Protocol (GHG Protocol) is the most widely used international accounting tool to understand, quantify, and manage greenhouse gas emissions. The GHG Protocol defines direct emissions as emissions from sources that are owned or controlled by the reporting entity.
  • The GHG Protocol also classifies direct emissions as "Scope 1". For more information on the GHG Protocol organizations can refer to:
    - Greenhouse Gas Protocol Standards
  • Direct GHG emissions are from sources that are owned or controlled by the reporting organization. For example, direct emissions related to combustion would arise from burning fuel for energy within the reporting organization's operational boundaries.
  • Organizations are also encouraged to report Greenhouse Gas Emissions Strategy (OI8237).
