The graph illustrates how many tons of carbon emitted by three different sources of fossil fuel in the United Kingdom, between 1990 and 2010.
Overall, Coal remained the primary source of carbon emissions throughout. Moreover, Gas and Oil after slight fluctuations saw stability until the end of the period.
In 1990, carbon emissions from Coal were the highest, at over 300 million tons, followed by Oil with approximately 275 million tons of carbon emitted. Gas had the lowest number of carbon emissions of all, at around 200 million tons. However, in 1995, Gas rose to more than 250 million tons of carbon released, whereas the figures for Coal and Oil both experienced a minor decline.
From 2000 onward, the trend reversed once again. After an initial drop, emissions from Coal rebounded to over 300 million tons, maintaining its position as the leading source of emissions in the later ten years. Oil saw an upward trend to around 275 million tons of carbon released in 2000, before holding steadily until 2010. Meanwhile, Gas lost its rank as the second largest source of carbon emissions, dropping to roughly 200 million tons in 2000 and remaining at this level for the rest of the period.
