The bar chart compares the distribution of carbon emissions generated from three types of fossil fuels – gas, oil, and coal – in the UK between 1990 and 2010.
Overall, a significant increase could be observed in the emissions from gas, while the figures for remaining fuel types decreased. Notably, coal and oil were the dominant categories in the earlier years, but gas became the prime source of emissions by the end of the period.
Looking at the details, in 1990, coal was the most significant source of carbon emissions, accounting for nearly 300 million tons, while oil represented around 270 million tonnes during the same period. Then, the figures for coal and oil dipped to about 270 and 240 million tonnes, respectively, in 1995. Thereafter, both sources saw further declines, reaching roughly equal levels of 250 million tonnes in 2000, before closing the period at their lowest points: approximately 190 million tonnes for coal and 210 million tonnes for oil.
As for gas emissions, they began the period at their lowest point of roughly 220 million tonnes and followed a considerable upward trend, reaching around 320 million tonnes – a highest figure in the entire dataset.
