We have now added data on CO₂ emissions per capita from fossil fuels going back to 1820 (or close to the start of the industrial use of fossil fuels). We have also added data on total emissions for the same country. A new example graph shows per capita CO₂ emissions on the Y axis and total emissions as the size of each bubble. This graph is available here.
