This interactive chart shows the year-on-year growth rate of CO2 emissions.
A positive figure in a given year indicates that emissions were higher than the previous year. A negative figure indicates they were lower than the year before. For example, a change of 1.5% indicates that global emissions were 1.5% higher than the previous year [–1.5% would mean they were 1.5% lower].
This measure allows us to see firstly where emissions are rising, and where they are falling; and secondly the rate at which emissions are changing – whether the growth in emissions are slowing down or accelerating.
