Cool Block program

Description: The Cool Block program (previously piloted in the California cities of Los Angeles, Palo Alto, and San Francisco) engages teams of neighbors living on a block (or in an apartment building) to reduce their carbon footprint by selecting from 112 “action recipes,” e.g., using less hot water, making their homes and appliances more energy efficient, eating less meat, storing sufficient emergency food and water. The final Cool Block Pilot will continue to refine the program while building a strategy to eventually scale the program to 375 blocks over three years.

Goal: Cool Block program: Enroll residents in program to reduce CO2 in their neighborhoods

Measurement: Percent decline in CO2 produced per year per 1000 residents

Time to Implement: Experience in Palo Alto pilot: two years to engage 30+ blocks, achieve 30% carbon reduction per household on average
