The graph illustrates the amount of carbon that is emitted from three distinct types of fossil fuel- including gas, oil and coal in the UK, over a 20-year period between 1990 and 2010.
Overall, it is evident that the level of carbon emissions from coal and oil increased, while the figure for gas decreased initially. However, each fuel contributed to emit carbon continuously without any fluctuation during 2000-2010, showing these features remained stable in that period.
To begin with, the highest amount of carbon emitted from coal, which accounted at around 310 million ton. This figure decreased marginally to 280 in 1995. Similarly, the amount of carbon emission from oil also saw a downward trend, dropping from approximately 270-240 million ton. By contrast, although 220 million ton carbon emitted due to using gas, this figure increased slightly to 270 five years later.
However, in 2000, all of fossil fuels recorded the opposite trend. In that period, the level of carbon emission from gas decreased to around 220 million ton, showing the lowest figure compared to others. But, oil and coal were highly responsible to emit carbon, at roughly 270 and 320 million ton, which was higher than before. After then, carbon emission from each fuel witnessed constant figure from 2000-2010.
