Fertilizer use is responsible for approximately 5% of total global greenhouse gas emissions. Emissions occur both during manufacturing (energy-intensive industrial processes) and field application (biological conversion of nitrogen to N₂O). The Fertilizer Emissions Calculator quantifies both sources.
Nitrous oxide (N₂O) is approximately 265 times more potent than CO₂ over 100 years. The IPCC estimates that 1% of applied nitrogen is converted directly to N₂O. Additionally, fertilizer manufacturing — particularly for urea and ammonium nitrate — requires significant energy from natural gas, adding to the total carbon cost.
Direct N₂O: N applied × 0.01 × 44/28 × 265 (GWP). Manufacturing CO₂: N × type factor + P₂O₅ × 0.6 + K₂O × 0.4. Manufacturing factors (kg CO₂e/kg N): Urea: 3.3, Ammonium Nitrate: 7.1, UAN: 4.7, Organic: 0.5.
Field N₂O typically accounts for 40–60% of total fertilizer emissions. Switching from ammonium nitrate to urea can halve manufacturing emissions. Using organic amendments has the lowest production footprint but may require larger quantities.
