COPENHAGEN: Denmark, which last year introduced a pioneering carbon tax on livestock farming, on Wednesday announced an agreement to cut nitrogen emissions from agriculture and curb water pollution. The Scandinavian country prides itself on being a leader in tackling global warming but waste from farming has stifled marine ecosystems. The deal aims to reduce nitrogen emissions by 9,600 tons a year using a quota system. “From 2027, farmers will receive an emissions quota based on the necessary reduction of nitrogen emissions in their catchment area,” the government announced in a statement.
