Dairy farmers in Denmark will have to pay an annual tax of 672 krone (around £75) per cow due to the planet-heating emissions they generate.
It is the world's first carbon emissions tax on agriculture, and while it has been broadly welcomed by Denmark's dairy industry, the move has angered some farmers.
The country's coalition government agreed on the tax this week, with new levies on livestock due to start in 2030.
Denmark is a major dairy and pork exporter, and agriculture is the country’s biggest source of emissions.
