In 2022, Aarhus Municipality in Denmark introduced an internal climate tax on its procurement of food items with high CO2 emissions. The tax targets beef, lamb and ready meals containing meat, as well as juice and sugar-sweetened beverages, which together account for one-third of the municipality’s food-related CO2 emissions. Initially, the tax was set at DKK 850 per emitted tonne of CO2. By 2023, it had been increased to DKK 1,000 per tonne and it is planned to reach DKK 1,500 by 2030. This progressive tax is applied during the procurement process to incentivise more sustainable purchasing practices.
