How have global emissions of carbon dioxide (CO2) changed over time?

In this chart we see the growth of global emissions from the mid-18th century through to today.

We see that prior to the Industrial Revolution, emissions were very low. Growth in emissions was still relatively slow until the mid-20th century. In 1950 the world emitted 6 billion tonnes of CO2

By 1990 this had almost quadrupled, reaching more than 22 billion tonnes

Emissions have continued to grow rapidly; we now emit over 34 billion tonnes each year

Emissions growth has slowed over the last few years, but they have yet to reach their peak
