The two pie charts illustrate greenhouse gas emissions worldwide in 2002 and the forecast for 2030, and the bar graph depicts carbon dioxide emissions around the globe.
Overall, more than half proportion of greenhouse gas was emitted by OECD in 2002, and it is estimated that it will decline by 2030. Whereas industry produced a high amount of carbon dioxide in 2002, and it is estimated that it will grew by 2030.
In 2002, 52% of greenhouse gas was emitted by OECD, 38% by developing countries, and only 10% by transition economies. However, it is estimated that in 2030, developing countries Will accouts for 48%, 43% for OECD, and 9% for transition economies.
In 2002, industries produced almost 6.2 billion tons carbon dioxide, whereas it is estimated that it will reach to around 11 by 2030. Similarly, consumers consisted of about 4 billion tons in 2002, and it is predicted that it will climb to 9 billion tons. Also, tansportation, waste combustion, and other sectors, produced relatively low amount of carbon than industries and consumers over the entire period.
