The concept of taxing sodas and other sugary beverages has gained traction recently across the United States and around the world. The World Health Organization officially recommended a tax on sugar sweetened beverages as a way to battle the obesity epidemic. In the US, multiple states and localities have looked to taxes on sugar sweetened beverages as a way to improve public health and increase revenue. In 2014, Berkeley, California became the first U.S. locality to enact such a tax. In 2016, similar taxes were enacted in Boulder, Colorado; Albany, Oakland, and San Francisco, California; Cook County, Illinois; and Philadelphia, Pennsylvania.
