The bar chart illustrates how much three different kind of greenhouse gases (including gas, oil and coal) were released in the United Kingdom over a 20-year period starting from 1990.
Looking at the chart, it is clear that there was an upward trend in the amount of gas emission was generated, while the opposite was true for coal emission. In addition, gas discharge registered the highest data for most of the period, which peaked in 2010.
In 1990, the amount of coal release was more than 300 tons, considerably higher than the figure for gas and oil emissions, which stood at nearly 200 and 250 tons respectively. Over the following 10 years, the amount of gas discharge witnessed a significant growth to about 300 tons while the release of coal fuel drop gradually down to 250 tons. In contrast, the quantity of oil emission remained unchanged after experienced a slight decline to 240 tons.
From 2000 to 2010, the production of gas fuel continue to rose drastically and reached a peak at about 320 tons, making it became the largest greenhouse gas was generated. Meanwhile, there was a steadily fall in the figure for oil and coal emissions which bottomed at around 210 and 190 tons respectively in the final year.
