How do you establish an effective emissions tracking baseline

Updated 9/9/2025

Establishing an effective emissions tracking baseline involves quantifying emissions from all relevant sources within an organization during a specific base year, ensuring that this baseline is accurate and comprehensive.

Why it matters

How to apply

  1. Select a Base Year:

    • Choose a year that reflects normal operational conditions without anomalies (e.g., major expansions, significant operational changes, or extraordinary events).
  2. Collect Comprehensive Data:

    • Gather data on emissions from all relevant sources:
      • Scope 1: Direct emissions from owned or controlled sources (e.g., fuel combustion).
      • Scope 2: Indirect emissions from the generation of purchased electricity, steam, heating, and cooling.
      • Scope 3: Other indirect emissions, such as those from the supply chain, waste disposal, and employee commuting.
  3. Use Established Protocols:

    • Follow frameworks like the GHG Protocol’s Corporate Standard or ISO 14064 to ensure consistency and accuracy in data collection and reporting.
  4. Ensure Data Accuracy and Completeness:

    • Verify the data through checks and audits to ensure it accurately reflects emissions for the selected base year.
  5. Document Assumptions and Methodologies:

    • Clearly document the methodologies used for calculations, data sources, and any assumptions made during the baseline establishment process.
  6. Review and Update Periodically:

    • Revisit the baseline regularly to account for changes in operations, organizational boundaries, and improvements in data collection methods.
