The pie charts illustrate data the percentage of three categories – OECD, transition economies, and developing in 2002 and 2030, while the bar provides details on the proportion of carbon dioxide emissions according to five different departments in the same time.
Overall, both OECD, and transition economies experienced downward trends, albeit to varying degrees over the 28-year period, whereas the reverse was true for developing countries, which saw a significant rise. By comparison, worldwide carbon dioxide emissions by all five sectors recorded an upward trend, although transportation, consumer, and industry, which grew considerably with different extends in 2002 and 2030.
Looking at the pie charts, OECD made up the highest figure in green gas emissions (52%). By 2030, this figure, however, will predict to drop profoundly to 43%. Similarly, the figure for transition economies will be able to decrease modestly from 10% in 2002 to 9% in 2030. Conversely, in can be seen that developing countries which might undergo a substantial growth to 48% at the end of the period.
Regarding the bar graph, both waste computation and other sectors registered the same level around 1 billion tons in 2002. However, while the former sector will have witnessed a modest rise to approximately 1.2 billion tons, the latter will be about 1.5 billion tons by 2030. In contrast, although three categories – transportation, consumer, and industry – recorded different levels, with figures standing at 2, 3.5, and 6.5 billion tons, respectively, they all will have seen a profound rise, almost doubled or more until 2030
