The bar chart given illustrates how much carbon dioxide has been released into the environment from burning gas, oil, and coal in the UK over the period from 1990 to 2010, measured in million tons.
Overall, carbon emissions from all three types of fossil fuel remained largely stable, without a temporary change in 1995. Carbon footprint from burning coal holds the largest category throughout the period, while gas was consistently the lowest.
In 1990, coal was the most significant polluter among the three types of fossil fuel, emitting approximately 315 million tons. The carbon emissions released by burning oil was the second largest contributor, producing roughly 270 million tons. In contrast, gas was the least polluting resource, stood at around 220 million tons, which was 100 million tons lower than the most polluting.
In 1995, all three categories showed the different statistic with the other. Gas emissions temporarily increased to approximately 320 million tons before returning 220 million tons in 2000 and remaining at this level thereafter. Conversely, the carbon emissions released from burning coal fell sharply to about 190 million tons in 1995. Meanwhile, oil emissions declined slightly to roughly 315 million tons before rutuning to approximately 270 million tons for 2000.
