The given bar chart compares the amount of carbon emissions produced by six countries from 1975 to 2005.
Overall, the amount of carbon dioxide in the USA, China, Canada, and India increased, with the USA showing the highest amount throughout the span, whereas the reverse was true for Germany and the United Kingdom. Notably, Canada’s carbon emissions production was the lowest despite the rise.
The USA and China dominated the carbon dioxide production. In 1975, 1,200,000 metric tonnes were produced in the USA, a figure that then rose substantially to 1,600,000 in 2005, consolidating its leading position. A similar trajectory was seen in the production of carbon emissions in China where the figure experienced a steep growth, going up from about 300,000 metric tonnes in 1975 to just above 1,400,000 by 2005.
There were modest increases in the amount of carbon outputs in India and Canada, but with less intensiveness than in the USA and China. In 1975, both India and Canada amounted to an identical amount of about 100,000. Afterwards, the growth accelerated, with the output reaching just under 200,000 in Canada and about 300000 in India.
By contrast, the carbon footprint in the UK and Germany decreased slightly over the period. Starting at merely over 200,000 metric tonnes in 1975, the figure for Germany, after levelling off at this point for the next 15 years, declined to exactly 200,000, whereas the amount of carbon emissions in the UK underwent a marginal fall from just under 200,000 in 1975 to about 160,000 metric tonnes by 1990; thereafter, it staged a slight recovery, closing the period with about 1,700,000 metric tonnes.
