The graph below contains information about carbon dioxide emission in East and West between 1988 and 2006

The graph illustrates carbon dioxide emissions in West and East, measured in millions of tons of carbon from 1988 to 2006 in 3 yearly intervals.

Overall, it is clearly that there was a significant increase in the quantity of emission in both areas over the eighteen years.

If we look at details, the largest quantity emission both in 1988 and 2006 was in West (4000 and about 4800 million tons, respectively), while the lowest both in the same time was in East (about 1900 and 4000 million tons, respectively). The amount of emission in the former area remained relatively stable from 1994 to 2003, rising to almost 4500 million of tons before growing slightly to a peak of about 4800 million level in the last 3 years of the period.

Moreover, in the latter area, after being constant at about 1800 million of tons during first 3 years, there was a fluctuation at 2000 million level. It is also interesting to note that this increased sharply to 4000 million tons of carbon over the next 9 years.
