Denmark has proposed a new tax on livestock farmers to reduce the country's greenhouse gas emissions. The tax, which is set to go into effect in 2030, will require farmers to pay for the methane emitted by their cows, sheep, and pigs. This move comes as the country aims to slash its GHG emissions by 70% by 2030. However, the proposal includes an income tax deduction and investment in green initiatives to support the industry's transition. The methane produced by ruminant animals such as cows and sheep through their digestive process is a potent greenhouse gas, contributing to global warming.
