New Method for Measuring N2O Emissions Can Help Address Food Security, Emissions Challenges

Researchers at Australia’s QUT have found a much more accurate means of measuring agricultural emissions of nitrous oxide (N2O) , a potent greenhouse gas that’s a significant contributor to total GHG emissions. Based on “groundbreaking data” on N2O emissions from a QUT colleague, QUT Institute for Future Environments Smart Futures Fellow Professor Richard Conant’s new statistical approach improves global N2O emissions estimates by as much as 65%.
