IMPORTANT NOTE: Please find an updated version of this dataset at https://doi.org/10.17863/CAM.86735

The dataset is the Matlab code used for the analysis in the paper "How to feed the global population with less greenhouse gas emissions from nitrogen fertilisers?". There are five folders.

1. In the 'Current status and BAU folder', please run Whole.m to obtain the current statues of GHG emissions from nitrogen fertilisers in 2019.
2. In the Uncertainty folder, run All.m to estimate the uncertainty of GHG emissions from synthetic nitrogen fertilizers.
3. In the folder called 2050, three files named as whole_process_*** correspond to different scenarios.
4. In the Uncertainty folder, run GHG_Emissions_Consumption_Regional_demand.m to obtain the 95% confidence interval.
5. In the manure folder, run whole.m to estimate the GHG emissions from manure in world regions..
