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.
