TLDR
In this paper, the ozone depletion potential-weighted anthropogenic emissions of N2O with those of other ozone-depleting substances were compared, and it was shown that N 2O emission currently is the single most important ozone-destroying emission and is expected to remain the largest throughout the 21st century.Abstract:
By comparing the ozone depletion potential-weighted anthropogenic emissions of N2O with those of other ozone-depleting substances, we show that N2O emission currently is the single most important ozone-depleting emission and is expected to remain the largest throughout the 21st century. N2O is unregulated by the Montreal Protocol. Limiting future N2O emissions would enhance the recovery of the ozone layer from its depleted state and would also reduce the anthropogenic forcing of the climate system, representing a win-win for both ozone and climate.read more

Site-specific 15N isotopic signatures of abiotically produced N2O
Jannis Heil,Jannis Heil,Benjamin Wolf,Nicolas Brüggemann,Lukas Emmenegger,Béla Tuzson,Harry Vereecken,Joachim Mohn +7 more
TL;DR: In this paper, the authors investigated the site preference (SP) of N2O produced by different abiotic reactions in a laboratory study and presented the first continuous analysis of δ18O in n2O.

Spatially explicit estimates of N2O emissions from croplands suggest climate mitigation opportunities from improved fertilizer management

TL;DR: This work applies a super-linear emissions response model to crop-specific, spatially explicit synthetic N fertilizer and manure N inputs to provide subnational accounting of global N2 O emissions from croplands, and estimates high-resolution N application data are critical to support accurate N 2 O emissions estimates.

TL;DR: The adoption of more sophisticated technologies in landfill sites (e.g. landfill gas flaring), waste-to-energy, as well as higher recycling rates, would enhance waste management in the region and mitigate environmental impacts.

Biochar increases nitrogen retention and lowers greenhouse gas emissions when added to composting poultry litter
Eunice Agyarko-Mintah,Annette Cowie,Bhupinder Pal Singh,Stephen Joseph,Lukas Van Zwieten,Alan Cowie,Steven Harden,Robert Smillie +7 more
TL;DR: The results support the co-composting of biochar to lower net emissions of GHGs while increasing N retention (and fertiliser N value) in the mature compost.

Seasonal and diurnal variability of N2O emissions from a full-scale municipal wastewater treatment plant.
Matthijs R.J. Daelman,Matthijs R.J. Daelman,Ellen M. van Voorthuizen,Udo van Dongen,Eveline Volcke,Mark C.M. van Loosdrecht +5 more
TL;DR: The diurnal Trend of the emission coincided with the diurnal trend of the nitrite and nitrate concentrations in the tank, suggesting that suboptimal oxygen concentrations may induce the production of nitrous oxide during both nitrification and denitrification.
