As Chief Sustainability Officer of Pacific Gas and Electric, Ezra Garrett carefully calculates ways the utilities provider can save its customers both economically and environmentally. Currently, PG&E’s water-conservation and energy-efficiency programs save Californians 1.3 billion gallons of water annually. Add that to a five-year plan to reduce the water used in PG&E’s buildings by 20%, and it means significant water retention for drought-strapped California. “Five years ago, corporate sustainability meant a focus on environmental issues relating to the way a company operates its business,” Garrett says. “The way that we define it now really spans the entirety of our efforts to provide safe, reliable, affordable service to our customers. It’s a focus on delivering our basic services, but doing that in a way that adds value to the communities that we serve and creates economic opportunities for our customers.”
