Definition (source: Our World in Data): Annual nitrous oxide emissions including land use. Measured in tonnes of carbon dioxide-equivalents over a 100-year timescale.

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).

Definition (source: The World Bank): Total population counts all residents regardless of legal status or citizenship. Values are midyear estimates.

Definition (source: The World Bank): Gross domestic product at purchaser's prices: the sum of gross value added by all resident producers in the economy plus any product taxes, minus subsidies not included in the value of the products. Data are in current U.S. dollars.

Definition (source: The World Bank): Gross domestic product divided by midyear population. Data are in current U.S. dollars.

Definition (source: iN-Net Policy Database): Count of nitrogen-related public policies and regulations enacted in each country in a given year, per the iN-Net policy database. Records whose date could not be parsed to a specific year are excluded here but are included in the "All Years" total.

Definition (source: The World Bank): Agriculture, forestry, and fishing corresponds to ISIC divisions 1-3 and includes forestry, hunting, and fishing, as well as cultivation of crops and livestock production. Value added is the net output of a sector after adding up all outputs and subtracting intermediate inputs, expressed as a share of GDP.

Definition (source: Our World in Data): Total land area used for cultivation of crops, in hectares. Distinct from cropland_area_pct, which expresses the same land use as a share of total land area.
