Annual Total CO2 Emissions by World Region

Ask a Question

  • This interactive chart and table display the annual total CO2 emissions by world region beginning in 1750.
Teaching Tips


  • This interactive resource provides two different ways for students to explore data (chart and table). Within these formats, students can focus on specific datasets of their choosing.
  • Students may choose to view datasets for the world or by region.
  • The resource includes links to additional related graphs for students to explore.
  • The Sources tab explains how the data was collected.

Additional Prerequisites

  • There are multiple layers of data to explore and navigate. Teachers should familiarize themselves with the various capabilities of the interactive and notice the various ways to add and remove datasets to the table and chart.
  • Students can click the "play" arrow below the chart or table to see how the data has changed over time.
  • Because the interactive provides so many options for viewing the data, students may need clear instructions as to which dataset to explore.


  • This interactive could be used in a geography class as students explore the data in conjunction with reviewing parts of the world.
  • As part of a science history lesson, this interactive could be used to explore the technological advancements that may have led to the increase in CO2 levels in some areas.
  • This interactive resource lends itself to exploring ratios and percentages, so it could be used during math lessons.

Scientist Notes

Tonnes of CO2 have been normalized and quantified with a conversion factor of 3.664. Global emissions have been statistically estimated with a rule of thumb to check the discrepancies in national emissions. These checks (methods) have ensured the quality of the datasets and the resource is valid for teaching.
