The bar graph below shows the amount of carbon emissions in different countries during three different years

The graph illustrates the number of carbon emissions produced by six different countries throughout the world in 1975, 1990, and 2005.
In General, The two largest contributors to carbon emissions were USA and China.
The USA consumed the largest proportion of carbon for all three years, showing an increase from marginally over 1.200.000 thousand metric tonnes in 1975 to just under 1.600.000 thousand metric tonnes in 2005. China's level of carbon emissions more than doubled from about 300.000 thousand metric tonnes in 1975 to over 600.000 thousand metric tonnes in 1990, before more than doubling again to approximately 1,6 million thousand metric tonnes in 2005.
In contrast, Germany's carbon emissions reduces slightly from 250.000 thousand metric tonnes in 1975 and 1990 to roughly 200.000 in 2005. The only other country to reduce emissions was the United Kingdom between 1975 approximately 180.000 and 2005 about 170.000 thousand. Canada's level increased slightly each year to match the UK's in 2005. Carbon emissions in India jumped from about 80.000 thousand in 1975 to 380.000 thousand in 2005.
