Public health lessons from the soda taxes enacted in France in 2012 and modified in 2018

Abstract

Abstract Background In 2016, the WHO officially recommended sugar-sweetened beverage (SSB) taxation as a strategy to reduce consumption, stimulate product reformulation and generate revenues for health-related programmes. This recommendation was based on a number of studies and experiments amongst them the 2012 French SSB tax that was redesigned in 2018. In this presentation, we summarize the lessons learnt from the soda taxes in France and offer insights on their potential public health benefits. Methods Our rationale is structured according to the interdisciplinary perspective of the Soda-Tax research consortium (2019-2023), addressing: (1) the soda tax policy change process; (2) the impact on price and purchases; (3) the consumer receptiveness to the tax and; (4) its legal framework and potential application to other foods/nutrients. Results Our overview of evidence highlights that the process leading to the enactment of the 2012 tax was initially based on a public health justification that was later set aside in favour of budgetary concerns. The tax, whose rate was flat and low and whose scope was extended to artificially-sweetened drinks containing no added sugar, generated modest effects on SSB consumption. Yet, it was ground breaking and offered an opportunity to appreciate its equity, to document its acceptance through a population-based survey and its legal viability. Six years later, the new tax comes closer to international recommendations: it is framed within the scope of public health action, focuses on SSBs and its rate is indexed to the quantity of added sugar in the drink. Conclusions The Soda-Tax project will study the degree of policy learning that may have contributed to the evolution of the 2018 tax, as well as the conditions of its implementation, administratively more complex than the previous one. It will also explore the social acceptability of this new tax and the extent to which it results in higher SSB prices, lower consumption and changes in the market. Key messages The design of the 2012 French soda tax was not optimal for public health, but it set a precedent. The 2018 soda tax, closer to international recommendations, deserves further investigation.
