The bar chart illustrates the number of emissions generated from three fossil fuels in Britain from 1990 to 2010.
Overall, the chart showed an upward trend in the number of tons in gas emissions, in contrast, the number of tons in coal emissions experienced a downward tendency throughout the given period. Besides, oil emissions had some fluctuations in the quantity.
As it is shown in the charts, gas generated more than 200M tons of emissions in 1990, then the number of emissions gradually rose during the period of 20 years from 1990 to 2010 and reached its peak at approximately 325M tons in 2010. On the other hand, the quantity of coal emissions was at its highest point of about 310M tons in 1990 and rapidly dropped throughout the given period. In 2010, the chart of coal emissions hit a low point of about 190M tons, which is less than the number of gas emissions.
It is worth noticing that the quantity of oil emissions fluctuated over a 20-year period. The number of emissions coming from oil started at about 275M tons in 1990, then decreased to around 240M tons in 1995 and rose to about 260M tons in 2000. However, the chart then witnessed a surprising fall over a 10-year period, declining from 260M tons in 2000 to below 200M tons in 2010.
