Study: Fertiliser use threatens global climate goals as nitrous oxide emissions soar

Emissions of nitrous oxide (N2O) – a greenhouse gas 300 times more potent than carbon dioxide – have risen by 20 per cent from pre-industrial levels, with agriculture responsible for the lion’s share of the increase, researchers from Auburn University in Alabama found.

“The dominant driver of the increase in atmospheric nitrous oxide comes from agriculture, and the growing demand for food and feed for animals will further increase global nitrous oxide emissions,” Tian said. “There is a conflict between the way we are feeding people and stabilising the climate.”

The study reveals that the regions contributing the most to global N2O emissions are East Asia, South Asia, Africa and South America, with emissions from synthetic fertilisers dominating releases in China, India and the US……
