The grouped bar chart illustrates the carbon emission levels from three types of fossil fuels, including gas, oil, and coal, in the United Kingdom between 1990 and 2010, measured in millions of tons.
Overall, carbon emissions from gas, oil, and coal in the UK remained relatively stable between 1990 and 2010, with the exception of a noticeable fluctuation in 1995. While gas emissions increased significantly that year, oil and coal emissions declined before returning to the original levels by 2000 and remaining constant thereafter.
In 1990, gas emissions were at 220 million tons, while coal emissions were the highest at 315 million tons, followed by oil at 270 million tons. By 1995, gas emissions had surged to 270 million tons, whereas oil and coal emissions both declined by approximately 30 million tons, dropping to 240 and 280 million tons respectively.
By 2000, the trends reversed: oil and coal emissions returned to their initial levels of 270 and 315 million tons, respectively, and remained stable until 2010. Meanwhile, gas emissions plummeted back to 220 million tons, matching their 1990 level and maintaining this figure through to 2010.
