Global Farm-Gate Nitrous Oxide Emissions Inventory 1961-2019

1961 to 2019 data from the FAOSTAT Emissions Totals domain provides estimates of nitrous oxide (N2O) emissions from agricultural and forest land activities, computed using IPCC Tier 1 guidelines. The dataset offers country-level and global coverage, with some projections to 2030 and 2050, and is maintained by the FAO. It quantifies emissions in kilotonnes and CO2 equivalents using AR5 global warming potentials.

Use Cases

• Analyze trends in N2O emissions by country from 1961 to 2019 to identify major contributors and reduction progress.
• Model future N2O emission scenarios for 2030 and 2050 using historical data and IPCC projection methodologies.
• Calculate aggregate CO2 equivalent emissions by applying AR5 global warming potentials to the N2O kilotonne data.
• Compare emission intensities across different crop and livestock activity categories within the agricultural sector.

Strengths

• 59-year time series (1961-2019) enabling long-term trend analysis.
• Global country-level coverage for comparative international studies.
• Data computed using standardized IPCC Tier 1 methodology ensuring consistency.

Limitations

• Projections to 2030 and 2050 are only available for some emission categories, not all.
• Tier 1 methodology is less detailed than higher-tier approaches, potentially affecting granular accuracy.
• The most recent complete data year is 2019, which may not reflect very recent changes.
