The bar chart compares the amount of greenhouse gas emissions caused by oil, coal and gas in the UK between 1990 and 2010.
Overall, the proportion of carbon emission produced by gas was higher throughout the period, except for the very beginning in 1990, when coal dominated. While the amounts of outputs resulting from both oil and coal declined, the reverse was true for gas.
Considering the proportion of carbon emissions produced by gas first, it climbed from about 225 million tons in 1990 to 275 million tons in 1995. After that, the number of CO2 emissions caused by gas increased steadily starting with 275 million tons in 1995 and reaching 300 million tons in 2005. Following a sharp rise in 2010, the gas emissions reached their peak with approximately 330 million tons.
Focusing on coal and oil emission sources, there is a decrease in the number of carbon releases due to oil in 1995 (from 275 to 250 million tons), which is followed by a rise in 2000, reaching 270 million tons. Starting from 2000 carbon emission caused by oil decreases consistently, showing 210 million tons in 2010. The outputs of carbon stemming from coal exhibited a sharp decline throughout the period, beginning at 315 million tons in 1990 and hitting 175 million tons in 2010.
