Definition (source: OECD): From the online data portal FAOSTAT maintained by the Statistics Division of the Food and Agriculture Organization of the United Nations (FAO) : 'Nutrient nitrogen' is defined as total nitrogen (N) from all fertilizer products. The 'Fertilizers by Nutrient' domain contains information on agricultural use, production, and trade of chemical and mineral fertilizers, in tonnes of nutrient, for the three main plant nutrients: nitrogen (N), phosphorus (expressed as P2O5) and potassium (expressed as K2O). The main data source for production and agricultural use is the FAOSTAT Fertilizers questionnaire, complemented with national publications when available. Agricultural use of fertilizers refers to the use for crops, livestock, forestry, fisheries and aquaculture, excluding use for animal feed. Industrial uses are excluded, to the extent allowed by data availability. Tonnes of nutrient nitrogen are calculated using conversion factors applied to volumes of nitrogenous fertilizers.

Definition (source: Our World in Data): A dataset describing the global warming response to national emissions CO2, CH4 and N2O from fossil and land use sources during 1851-2024. National CO2 emissions data are collated from the Global Carbon Project (Andrew and Peters, 2025; Friedlingstein et al., 2025). National CH4 and N2O emissions data are collated from PRIMAP-hist (HISTTP) (Gütschow et al., 2024). We construct a time series of cumulative CO2-equivalent emissions for each country, gas, and emissions source (fossil or land use). Emissions of CH4 and N2O emissions are related to cumulative CO2-equivalent emissions using the Global Warming Potential (GWP*) approach, with best-estimates of the coefficients taken from the IPCC AR6 (Forster et al., 2021). Warming in response to cumulative CO2-equivalent emissions is estimated using the transient climate response to cumulative carbon emissions (TCRE) approach, with best-estimate value of TCRE taken from the IPCC AR6 (Forster et al., 2021, Canadell et al., 2021). 'Warming' is specifically the change in global mean surface temperature (GMST). The data files provide emissions, cumulative emissions and the GMST response by country, gas (CO2, CH4, N2O or 3-GHG total) and source (fossil emissions, land use emissions or the total).
