From 2030, farmers in Denmark will have to pay a tax for their animals’ farts.
This is because cow, sheep and pig burps and farts produce a greenhouse gas called methane, which contribute to global warming and climate change.
The “flatulence tax” means farmers will have to pay 300 kroner (£34) per tonne of methane that their animals produce in a bid to drive down Denmark’s emissions.
This has been decided after months of debate between the country’s major political parties, Danish farmers, trade unions and environmental groups.
It is called The Green Tripartite agreement.
