The number of emissions produced in Britain between 1990 and 2010 from three fossil fuels is depicted in the bar chart.
Overall, the graph indicated an increase in the quantity of petrol emissions; however, over the course of the time period, the quantity of coal emissions exhibited a negative tendency. ‘ jji9In addition, there were variations in the amount of oil emissions.
It can be seen that gas produced more than 200 million tonnes of emissions in 1990. Over the next 20 years, emissions increased gradually and peaked in 2010 at almost 330 million tonnes. Conversely, the amount of coal emissions peaked in 1990 at over 310 million tonnes and then significantly decreased over the course of that time. The coal emissions graph peaked in 2010 at 190 million tonnes, which is less than the total amount of petrol emissions.
It is noteworthy that within a 20-year period, there were variations in the amount of oil emissions. Oil-related emissions peaked in 1990 at over 275 million tonnes, declined to approximately 240 million tonnes in 1995, and then increased to roughly 260 million tonnes in 2000. But during the next ten years, the chart saw an unexpected decline, going from 260 million tonnes in 2000 to less than 200 million tonnes in 2010.
