How Much Have We Polluted? is an interactive heat map that displays the per capita and yearly total of CO2 emissions for individual countries. The map contains data dating back to 1960. Move the time slider to the heat map change. You can use the map to compare the emissions of two countries year-by-year.
Applications for Education
How Much Have We Polluted? is obviously a good way for students to see comparisons of emissions from different countries. Simply moving the time slider shows how much emissions have increased over time. After they compare the emissions from two or more countries, ask your students to investigate the causes of the differences in per capita CO2 emissions between countries.
