Irish Universities Urge Government to Increase Sugar Tax Amid Stalled Progress

Researchers from four Irish universities are urging the government to increase Ireland’s sugar tax, citing a need for stronger measures to combat rising obesity and encourage further sugar reduction by manufacturers. This appeal follows new figures showing the Sugar-Sweetened Drinks Tax (SSDT) revenue remained at €30.5 million in both 2024 and 2025, suggesting stalled progress.

The current tax rates, introduced in 2018, levy about five cent on a 330ml can for drinks with 5-7.99g of sugar per 100ml, and eight cent for those with 8g or more. While these rates initially prompted major brands like Pepsi and Fanta to reformulate products below the taxable threshold, researchers argue the incentive for further reduction has weakened. They propose Ireland adopt the UK model, which will gradually lower the tax threshold over the next decade.

Dr. Frank Houghton of the Technological University of the Shannon (TUS), who led the study published in the Irish Medical Journal, stated the levy was effective but needs to go further to encourage additional reformulation. The researchers also advocate for ring-fencing the tax revenue for obesity prevention programs, treatment services, and community food initiatives. Over 115 countries have implemented sugar taxes, with estimates indicating about 60% of Irish adults and 20% of children are overweight or obese.
