The pie chart, combining with the bar chart, illustrates the landscape of emissions around the world, which is estimated from 2002 to 2030. Overall, there are three significant factors in terms of gas emissions and five sectors in carbon dioxide creation affected to the given data in this period.
In detail, 2002, the most significant propotion holds for OECD at almost half of the pie. While both transition economies and developing countries emitted with the figure of 38% and 10% respectively. But this trend stands almost the same in the year of 2030, when OECD seems to be reduced 5%, leaving developing countries rises almost double of the former loses. Transition economies is expected to have slight drop with the percentage of 1%.
In terms of Carbon Dioxide, Industry held the largest figure with 6 billion tons and said to be skyrocket to 10 billion tons, followed by consumer around 4 billion tons in the year of 2002, are projected to be double its emissions. Transportation, the third largest categories, with the initial figure of approximately 2 billion tons, could potentially triple its load by the year of 2030. Both waste and other sectors, in 2002, are no different from the figure at 2030.
