The line graph compares information about the amount of CO2 emissions per individual in Singapore, China, Thailand and Vietnam over a 35-year period.
It is evident that the average Carbon emissions per person in all four countries showed an upward trend throughout the given duration. And also notable that the figure for Singapore was significant higher than those in the other countries.
The personal CO2 emission rate in Singapore stood at around 11 in the first year, after which it fluctuated slightly and peaked at about 14 in 1990. The figure then fell twofold to approximately 7 in 2005 before increasing exponentially and bounced back to the initial figure in the final year.
In contrast, the amount of Carbon emissions per capita in China and Thailand were similar (around 1) in 1975 then climbed gradually during the next 20 years. The amount then remain unchanged until 2000 before growing steadily in the last year. Despite the slight growth from 1995 to 2010, Vietnam’s per capita Carbon emissions remained almost stable in previous years and hovered around 1.
