Denmark is introducing a world-first tax on farmers, with each cow generating a annual fee of 100 euros, as part of efforts to reduce greenhouse gas emissions. The tax, agreed upon by the government, farmers, and unions, will rise from 40 euros per tonne of CO2 in 2030 to 100 euros in 2035. Initially, farmers will receive a 60% tax reduction, resulting in an annual cost of 100 euros per cow in 2035, up from 16 euros without the reduction. This measure, expected to be mirrored across the EU, replaces New Zealand's abandoned similar policy.
