Nitrous Oxide Emissions

Ask a Question

  • This resource includes an interactive map and graphs that show the total nitrous oxide emissions for countries throughout the world, starting from 1990. 
  • Nitrous oxide (N₂O) emissions are measured in tonnes of carbon dioxide equivalents (CO2e) based on a 100-year global warming potential value. 
Teaching Tips


  • The interactive provides three different ways for students to explore data (chart, map, table).
  • Students may choose to view datasets for various geographic locations and time periods.
  • Related research and data are linked.
  • The site explains how the data was collected.
Additional Prerequisites
  • Learners need to be familiar with the concept of gas emissions.
  • Educators would need time to get familiar with this interactive media and decide on how to implement it with the learners.
  • Can be used as a practical application of the uses of line graphs learned in Statistics and Mathematics.
  • There are other related interactive maps for sources of emissions.
  • Useful for creating awareness about one or more of the Sustainable Development Goals (SDGs).
Scientist Notes

This resource outlines Global N2O emissions aggregated from selected countries. Ideally, Global warming potentials for N2O was calculated within a period of 100 years was taken into account to get the sum of CO2 equivalent expressed in tonnes. This resource is recommended for teaching.
