The move is sure to reduce litter—but not necessarily planet-warming emissions.

Update, September 30, 2014: On Tuesday, Governor Jerry Brown signed SB270 into law, making California the first state to ban single-use plastic bags. The law is set to begin going into effect in July 2015.
Last month, California became the first state to pass a bill banning the ubiquitous disposable plastic bag. If signed into law, the measure will prohibit grocery and retail stores from providing single-use plastic bags and require them to charge at least 10 cents for paper bags, compostable bags, and reusable plastic bags. The bill, introduced by Sen. Alex Padilla (D-Los Angeles), will also provide funding for California-based plastic bag companies to develop sturdier, reusable options.
Worldwide, consumers use an estimated 1 trillion plastic bags each year—nearly 2 million a minute—with the use time of a typical bag just 12 minutes. Californians alone throw away 14 billion a year, creating 123,000 tons of waste and untold amounts of litter.
There is evidence that bag bans and taxes can cut down on some of this waste: Ireland’s 2002 tax cut bag usage between 75 and 90 percent. An analysis of bag use in Australia found that 72 percent of customers accepted single-use bags that were offered for free. When a nominal fee was charged, usage dropped to 27 percent (33 percent switched to reusable bags and 40 percent made do without).
