December 11, 2012 – These days, there’s a lot of discussion of carbon footprints. A new study by the Pacific Institute focuses on another footprint, that of water. The report, released Tuesday by the Oakland-based think tank, takes a look at the amount of water required to produce the goods Californians consume, whether it’s the food we eat or the things we buy; whether they are produced in state or imported from other states or foreign countries. California’s total water footprint is about 64 million acre-feet, or 20 trillion gallons of water, per year, according to the study. More than half of that is used to produce goods that are imported and consumed here.
