What were some of the changes implemented? Chatterjee says that Palo Alto's chief of police looked at his department and zeroed in on the air conditioning in the Canine Unit. "He realized that if I could turn off the HVAC and put on fans, the dogs would see no change, but I would no longer have to be reliant on HVACs to cool that system." According to Chatterjee, because of Hara's improvements, the city of Palo Alto has seen between $600k-$800k in savings each year.
Chatterjee also talks about the idea of a tax on carbon, and what questions we should be asking ourselves before endorsing the idea. "The first is: is it actually a meaningful proxy for natural resources consumed? Secondly, what’s the emotional tie to it? And thirdly, whether it's feasible. Whether or not organizations should be able to deal with it."
