A framework to assess the effect of N management on yield and GHG emissions. The framework was applied to Australian rainfed wheat systems. Opportunities exist for enhancing yield while reducing GHG emissions. Improved N management could increase yield by 76% and reduce GHG emissions. This N management can be specified according to local soil and climate variables.
