A national research effort is aiming to cut nitrous oxide (N2O) emissions from nitrogen fertilizer, a major source of greenhouse gases in Canadian agriculture.

The Canadian Nitrous Oxide Network (canN2Onet) is a collaborative 4-year research project led by N2O experts, including six universities, one college and one polytechnic. These institutions include Lethbridge Polytechnic, Olds College, University of Saskatchewan, University of B.C. and the University of Guelph. The University of Guelph is the lead in research for the nitrogen fertilizer project.

This research project was established in 2024 by Guelph professor Claudia Wagner-Riddle and was federally funded with $7.9 million from the National Sciences and Engineering Research Council of Canada (NSERC).
