The supplied diagram depicts data about the volume of a wide range of emission sources of greenhouse gas between 1990 and 2010 in the UK. On the whole, both gas and coal sectors exhibited opposing trends; the former grew progressively each year, whereas the latter contracted annually. Furthermore, there was a fluctuation in the amount of oil.
Focusing on the period from 1990 to 1995, the amount of coal was predominantly higher than that of gas and oil. With the coal and oil having reached peaks of almost 300 and 260 million tons in 1990, the amounts then began to fall sharply, to 270 and 240 million tons in 1995, respectively. The amount of gas, on the other hand, experienced a rough increase from about 210 to 260 million tons.
By contrast, between 2000 and 2010, the figure for gas was dominat, whereas coal had the lowest rates. The amount of gas extended its growth from about 300 to around 350 million tons, contrasting sharply with the figure for coal, which saw a further decline from 250 to nearly 200 million tons. Finally, the figure for the oil decreased minimally from around 240 to 220 million tons throughout the period between 2000 and 2010.
