The bar chart illustrates how much carbon emissions were released from gas, oil and coal in the UK throughout a 20-year period starting from 1990.
Overall, there was an increase in the amount of greenhouse gas emitted from burning gas, while the oil and the coal witnessed a downward trend. In addition, at the beginning of the period examined, coal was burned and released the most carbon emissions, but the reverse was true in the final year.
In 1990, the quantity of carbon emissions from coal started at just over 300 million tons, after which it experienced a slight decline to around 270 million tons but still remained the highest position after 5 years. This figure continued to steadily decrease and reached its bottom at just under 200 million tons in 2010. Similarly, the amount of greenhouse gas produced from oil was roughly 265 million tons in the first year, followed by a gradual drop to just under 200 million tons in 2010, despite an insignificant rise in 2000.
By contrast, approximately 220 million tons of carbon emissions were generated by using gas in the UK, with a subsequent dramatic growth to exactly 300 million tons after a decade. In the last 10 years, this figure then kept rising by 10 million tons every five years and peaked at 320 million tons in 2010.
