The bar chart illustrates the changes in carbon dioxide emissions across six countries over the period from 1975 to 2005 at 15-year intervals, with figures expressed in thousands of metric tonnes.
Overall, it is evident that the USA and China saw a clear upward trend in carbon emissions, with China experiencing a sharp increase, while Germany and the United Kingdom experienced a slight decline. Canada and India rose on average, with India experiencing a significant growth.
In 1975, The USA’s carbon emissions stood at 1.2 million tonnes. Then, it rose moderately to around 1.3 million tonnes in 1990, before reaching a peak of 1.6 million by 2013. Similarly, China started with approximately 300 thousand tonnes . Subsequently, this figure experienced a rapid rise from 1990 to 2005, beginning with 700 thousand and finishing with roughly 1.5 million tonnes, respectively. However, India’s emissions were lower compared to others at less than 200 thousand in 1975, followed by a gradual climb to around 300 thousand.
On the other hand, human-generated carbon emissions in Germany were relatively stable at over 200 thousand in 1975, falling to 200 thousand at the conclusion of the period. The United Kingdom fluctuated between 180 and 200 thousand tonnes. Canada’s emissions increased steadily from around 150 thousand in 1975 to approximately 180 thousand by 2013.
