Agriculture is one of the largest sources of greenhouse gas emissions in Denmark, accounting for approximately 11–12 million tonnes of CO2-equivalent annually, or roughly one-third of Denmark's total domestic emissions (which were approximately 33–35 million tonnes CO2-eq in 2023). This makes Danish agriculture proportionally one of the most emission-intensive agricultural sectors in the EU. The primary sources are: methane from livestock (particularly cattle), nitrous oxide from fertiliser application and manure management, and CO2 from drained peatlands/wetlands (formerly the largest single agricultural emission source). Denmark's intensive agricultural sector — which produces far more food than the country consumes (Denmark is a major exporter of pork, dairy, and grain) — has faced increasing pressure under the EU's climate framework to reduce emissions. In 2024, Denmark became the first country in the world to impose a direct tax on agricultural greenhouse gas emissions (effective 2030), with a rate of DKK 300 per tonne of CO2-equivalent rising to DKK 750 by 2035.
