Question 1
a)
Producer countries of CO2 emission in 2009 and 2013
In 2009, the fifteen countries co2 emission was high at 20500 metric tons while in 2013
the emission of CO2 was at25740 metric tons. In 2009 and 2013 china was the leading
country in emission of CO2 followed closely by United States and the country with the
least emission volume was Australia (Roberts, et al., 2019).

Analysis of CO2 Emission, Welding Time, and Inflation Rate in Australia_1
The percentage of CO2 broken down by the producer countries in 2009 was 44% as
presented by the blue color on the pie chart while the maroon color represent the
percentage 56% of CO2 broken down in 2013.
c)
From the two graphical techniques that is the bar graph on Producer countries of CO2
emission in 2009 and 2013 and the pie chart on Total percentage of CO2 emission in
2009 and 2013 it is observed that both techniques shows that it is in 2013 that the
emission of CO2 was high compared to 2009.Observation made on the bar graph on
Producer countries of CO2 emission in 2009 and 2013 is that china and United states
are the leading emitting countries of CO2.
