The bar chart compares the level of carbon emissions from three different kinds of fossil fuel in the United Kingdom between 1990 and 2010.
In general, carbon emissions from all three types of fuel remained relatively unchanged throughout the period, with a temporary fluctuation in 1995. In addition, coal consistently recorded the highest level of emissions, followed by oil, while gas remained the lowest contributor.
In 1990, coal was the significant polluter among three types, emitting around 330 million tons. Oil followed as the second-largest contributor, standing at approximately 270 million tons. By contrast, the figure for gas exhibited the least pollution which was only roughly 220 million tons.
In 1995, the gas increased temporarily to about 270 million tons moving to the second but then returned to 220 in 15 following years. Conversely, the figure for oil dropped to under 250 million tons being the least polluting before recovering to around 270 in 2000 onward. Ultimately, despite falling to about 280 million tons, coal was still the largest pollution which would rebound to over 300 and stay constant throughout the period.
