New RAEL analysis of UC Berkeley's carbon footprint: 97% of emissions are indirect
RAEL, in collaboration with the UC Berkeley Office of Sustainabilty, has developed a new hybrid life cycle model to estimate of the carbon footprint of UC Berkeley. Total emissions are 424,000 metric tons for the year 2008.
Direct emissions (Scope 1) are only 3% of the University's total carbon footprint. Indirect emissions from purchased energy (Scope 2) account for 37% of the total, with 60% from other indirect sources (Scope 3). The official UC Berkeley greenhouse gas inventory includes roughly 50% of the total carbon footprint.
The goals of the new RAEL study are:
- to improve upon some of the shortcomings of UC Berkeley’s previous carbon footprint assessment for the year 2006,
- to provide an updated estimate of UC Berkeley’s carbon footprint for the years 2006, 2008 and 2009,
- to ensure the assessment is compliant with the newly proposed World Resources Institute standards for Scope 3 reporting,
- to suggest potential strategies for supply chain emission reductions,
- to produce a spreadsheet tool to facilitate annual monitoring of carbon footprint data in the future,
- to explore uncertainty in the model, and
- to suggest improvements for future carbon footprint assessments.
