The bar charts compare the proportion of greenhouse gas emissions worldwide in 2002 and prediction for 2030 and the chart illustrates global carbon dioxide emissions forecast among five sector in billions of tons.
Overall, the most striking feature is that OECD accounted for the highest figure while the reverse was true for transition economies over the period given. In terms of bar chart, industry stood as a leading sector while waste combustion and other sector accounted for the least throughout the year.
Starting with pie charts, OECD recorded the biggest proportion with 52% which was significantly higher than that of transition economies and developing countries, with just 38% and 10% in 2002. Additionally, the difference between developing countries and transition economies were significantly, with respective figures of 48% and 43% respectively prediction for 2030. Whereas the figure for transition economies also accounted for the least with 9% greenhouse gas emissions the forecast 2030.
Tuning to bar chart, industry demonstrate a biggest contribution for both 2002 and prediction for 2030, with just 6 billions tons and almost 11 billions tons. It is evident that the figure for wade conbution and other sector was similar but negligible, with just nearly 2 billions tons and almost 1 billions tons over the period given. Transportation constituted at around 7 billions tons in 2002 and representing 2 billions tons forecast for 2030. Finally, the amount of carbon dioxide emission for consumer showed considerable difference over the year, with just 9 billions tons compared to 4 billions tons.
