Denmark has become the first country to introduce a tax on methane emissions from cattle and pigs, with the tax set to be implemented from 2030 as part of a commitment to achieve carbon neutrality by 2045. The initial tax rate will be 40.2 euros per ton of CO2 equivalent, rising to 100 euros by 2035. Despite the tax, farmers are expected to see a reduction in their costs, with the actual cost per ton of CO2 equivalent dropping to 16 euros in 2030 and 40 euros by 2035 due to offsetting tax breaks. This move is part of a wider agreement aimed at promoting sustainable agriculture, which was reached in late June.
