The Global Nitrous Oxide Assessment shines a spotlight on a critical but often overlooked climate threat. Nitrous oxide, a potent greenhouse gas and a top ozone-depleting substance. Nitrous Oxide is mostly emitted from synthetic fertilisers and manure in agriculture.    Rising faster than expected, its emissions threaten both our climate and ozone layer. The report highlights actionable steps to cut emissions by over 40%, with deeper reductions achievable through transformations in food systems and society.    As part of the essential nitrogen cycle, nitrous oxide plays a crucial role in our global food system but demands urgent attention for sustainable solutions.
