A soda tax or sugary drink tax is a tax designed to reduce consumption of drinks with added sugar. Drinks covered under a soda tax often include carbonated soft drinks, sports drinks, and energy drinks. The tax is a matter of substantial public debate in many countries, regions, and cities. Beverage producers such as Coca-Cola have generally opposed soda taxes. Advocates such as national medical associations and the World Health Organization promote the tax as an example of Pigovian taxation, aimed to discourage unhealthy diets and offset the growing costs (economic and social) of obesity. The main issues include whether: there is a health crisis that a soda tax can address; soda and sugary drinks contribute to health crises around the world; taxing soda can effectively reduce consumption; funding from a soda tax can meaningfully contribute to the economic health of a local government and help fund educational and health programs; a soda tax is regressive in that it may affect lower-income individuals to a greater extent; and whether a soda tax alone or a sugary-beverage tax is appropriate. Some of the cities in the United State that have adopted soda taxes include Seattle, San Francisco, Berkeley, Oakland, and Philadelphia. See the Wikipedia article on soda taxes for more basic background.
Dr Douglas Bettcher, Director of WHO’s Department for the Prevention of NCDs, said: “Consumption of free sugars, including products like sugary drinks, is a major factor in the global increase of people suffering from obesity and diabetes. If governments tax products like sugary drinks, they can reduce suffering and save lives. They can also cut healthcare costs and increase revenues to invest in health services.” The problem is sizable, as the WHO describes: “In 2014, more than 1 in 3 (39%) adults worldwide aged 18 years and older were overweight. Worldwide prevalence of obesity more than doubled between 1980 and 2014, with 11% of men and 15% of women (more than half a billion adults) being classified as obese. In addition, an estimated 42 million children aged under 5 years were overweight or obese in 2015, an increase of about 11 million during the past 15 years. Almost half (48%) of these children lived in Asia and 25% in Africa. The number of people living with diabetes has also been rising, from 108 million in 1980 to 422 million in 2014. The disease was directly responsible for 1.5 million deaths in 2012 alone.”
Dana Hunnes, senior dietitian at Ronald Reagan UCLA Medical Center: “They are really among the worst things we can drink. They are not only empty calories, but they also provide no beneficial nutrient intake whatsoever. If we drink 250 calories of soda, we may still eat the same amount in calories of food later. But if we eat 250 calories of food, we’ll probably eat 200 or 300 fewer calories later. The insulin response may in fact make us hungrier afterward.”
According to research from the UCLA Center for Health Policy Research and the California Center for Public Health Advocacy, adults who drink one soda or more per day are 27% more likely to be obese.
“Proponents of soda taxes often reference the success of cigarette taxes in decreasing cigarette use. However, cigarettes and soda differ in a number of ways. First, cigarette taxes increase prices significantly, a tactic that may be unjustifiable for soft drinks given that, unlike cigarette use, moderate soda consumption is considered safe. Second, the many available soda substitutes may render soda taxes ineffective, in that consumers will replace highly-taxed beverages with low-tax alternatives with the same health consequences.” According to a 2012 Cornell University study, soda taxes prompted many consumers to switch to beer, and another study suggests that consumers may replace soda with other high-calorie alternatives.
“Sugar-sweetened soft drinks are disproportionately consumed by the poor and people of color, making accusations of â€œnanny stateâ€ elitism impossible for proponents to avoid. Providing grist to critics, billionaire Michael Bloomberg â€” the former New York City mayor already known for his widely mocked attempt to ban â€œBig Gulpsâ€ in the Big Apple â€” contributed more than half a million dollars into Berkeleyâ€™s local soda tax election. Kenney decided to put a new spin on the soda surcharge when he proposed it in Philadelphia. Rather than pitching it as a way to ‘nudge’ the poor into drinking less soda, Kenney linked the tax to a popular progressive measure: universal pre-kindergarten.”
A 2016 report in the American Journal of Public Health found that low-income Berkeley neighborhoods slashed sugar-sweetened beverage consumption by more than one-fifth after the Northern California city enacted the nation’s first soda tax. Berkeley voters in 2014 levied a penny-per-ounce tax on soda and other sugary drinks to try to curb consumption and stem the rising tide of diabetes and obesity. After the tax took effect in March 2015, residents of two low-income neighborhoods reported drinking 21 percent less of all sugar-sweetened beverages and 26 percent less soda than they had the year before. The World Health Organization has also found: “Taxation of certain foods and drinks, particularly those high in saturated fats, trans fat, free sugars and/or salt appears promising, with existing evidence clearly showing that increases in the prices of such products reduces their consumption.”
Dana Hunnes, a senior dietitian at Ronald Reagan UCLA Medical Center: “We know that education has mostly failed. Educating people to drink fewer sugar-sweetened beverages only works to a point. After that, taxation on an unhealthy product — along with putting those taxes toward public health programs — would help far more.”
“It might not be popular. But it’s working. Latin America’s largest Coca-Cola bottler, Coca-Cola Femsa, yesterday reported weak Mexican sales volumes, which slipped 2.8% during the quarter excluding the impact of mergers and acquisitions, as a new excise tax on soda ate into consumer demand for sugary drinks. Rival Arca Continental reported a similar sales slip in Mexico, as did Pepsi bottler Organizacion Cultiba. While soda makers might grumble, the decline of Mexican soda sales is rather good news.”
“A Cornell-University of Iowa analysis of a soda tax passed last fall by voters in Berkeley, California, the first such city ordinance in the country, found the measure so far has fizzled, raising retail prices for high-calorie sugary drinks by less than half the amount expected. The law, which took effect this March, imposes a penny-per-ounce tax on distributors of sugar-sweetened beverages, such as soft drinks, energy drinks and presweetened teas. Distributors pay 20 cents per 20-ounce bottle of Coke, for instance. Tax proponents expected the extra cost to result in higher prices for shoppers, which would discourage soda consumption. To date, however, consumers have been largely spared from higher prices, researchers found. On average, prices for beverages covered under the law rose by less than half of the tax amount. For Coke and Pepsi, only 22 percent of the tax was passed on to consumers. The findings, by economists John Cawley of Cornell and David Frisvold of the University of Iowa, appear in the National Bureau of Economic Research working paper, “The Incidence of Taxes on Sugar-Sweetened Beverages: The Case of Berkeley, California,” published Aug. 17. “In light of the predictions of the proponents of the tax, as well as in light of the previous research, we expected to see the tax fully passed through to consumers,” said Cawley, professor of policy analysis and management and of economics in Cornell’s College of Human Ecology. “In contrast, we find that less than half, and in some cases, only a quarter of it is. This is important because the point of the tax was to make sugar-sweetened beverages more expensive so consumers would buy, and drink, less of them.” So-called “sin taxes” are designed to improve public health by discouraging people from purchasing unhealthy products. Smoking rates, for instance, have plummeted in the United States in recent decades partly due to federal, state and local taxes that have driven up cigarette costs. Berkeley officials hoped that the soda tax would raise prices and lead residents to avoid energy-dense sugar-sweetened beverages, considered a culprit for high rates of obesity and chronic disease. “The reason for this surprising result could be related to the fact that it’s a city tax and therefore store owners have to be concerned about the ability of consumers to shop at stores outside of Berkeley,” Cawley said. “Concerns about cross-border shopping could contribute to a low pass-through of the tax.””
