The line graph below illustrate CO2 release in metric tonnes per capita, between 1975 and 2010 in four different countries.
Overall, it can be observed that Singapour produced the large number of carbon dioxide in those years. While other three countries such as Vietnam, China, and Thailand realesed the smaller number of CO2.
Singapour reduced their chemical emissions from 11 to 7.5 metric tonnes per capita from 1975 to 2005. But in 2010 amount of CO2 that realeses to atmosphere, increased to previous 11 metric tonnes. Also another country which increased their emissions is China. China realesed just under 2 metric tonnes per capita in 1975. However, in 2010 the degree increased to about 5.9 metric tonnes per capita.
Thailand also increased the level of emissions such as China, from 1 in 1975 to just about 4 metric tonnes in 2010. The Vietnam is the lowest one. The degree of emission raised from also 1 to 2 metric tonnes in 35 years.
