The bar chart depicts various emission sources (coal, oil, gas) of greenhouse gas, from 1990 to 2010 in the United Kingdom.
Overall, while gas increased, oil and coal underwent decrease over the period.
Between 1990 and 1995, carbon emission from gas rose gradually at around 225 and 275 million tons respectively. By 2000, it continued to rise slightly from approximately 275 to 290 million tons of carbon emission from gas. From 2005 and 2010, carbon emission from this kind of fossil fuel still went up moderately at 290 and 350 billion kg respectively.
Between 1990 and 2000, the number of million tons produced by carbon emission from oil fluctuated from 275 to nearly 250, and decade after 2000, it started to fall gradually from just around 260 to 200 billion kg. On the other hand, carbon emission from coal underwent a slight decrease over the period, starting with 310 billion kg and ending with 200 million tons.
