All statistics shown are the most recent available as of late 2020, and the most recent year varies with dataset. The IEA’s dataset more thoroughly accounts for biofuels, but lags behind BP’s by a year.
Carbon intensity described here is that of total energy supply, which is the quantity of carbon emitted per unit of energy from all fuels, both combustible and non-combustible.
World carbon intensity had been declining since the 1960s, until year 2000, and didn’t return to this level until year 2016. Humanity made no progress to decarbonise the world energy system during this 16 year period, and the rate of decarbonisation since has been roughly the same as that during 1990-2000.
Carbon intensity values of world economies in 2019 are shown in the upper row of charts below, in red. The dotted line is world average. Changes relative to 1999 (two decades prior) are shown in the bottom row, in blue, with the dotted line denoting no change.
- BP does not fully account for biofuels, and these may not be carbon-neutral, as explained at https://www.worldenergydata.org/biofuels/
- Biofuels on this website are the summation of solid and liquid biofuels, and therefore Geothermal, Biofuels and Other equals the summation of BP’s data for ‘Geo, Biomass and Other’ and ‘Biofuels’.
