Carbon Intensity (CI) Summary Carbon Intensity (CI) measures how efficiently an organization, product, or investment portfolio generates economic value relative to its greenhouse gas emissions. Emissions are measured in tons of CO₂ equivalent (tCO₂e), used to assess environmental and sustainability performance. Formula (Text Format): CI = Total Emissions (tCO₂e) / Economic Output Total Emissions: Includes Scope 1, Scope 2, and optionally Scope 3 emissions. Economic Output: Can be Revenue, Total Assets, Invested Capital, or Production Volume. Applications: ESG reporting (TCFD, ISSB standards) Investment portfolio carbon risk assessment (PCAF standard) Corporate management and production efficiency analysis Example: If total emissions = 10,000 tCO₂e and revenue = $200 million: CI = 10,000 / 200 = 50 tCO₂e per $1M Revenue Lower CI indicates better carbon efficiency and stronger low-carbon performance. Consistent calculation standards are critical for industry benchmarking.
