The pie graphs show greenhouse gas emissions worldwide in 2002 and the forecast for 2030. The column chart shows carbon dioxide emissions around the world.

Question

The pie charts give the information about gas emissions worldwide in the past 2002 and compare to future data in 2030, while the column chart illustrates the amount of carbon footprint by sectors, namely waste contribution, transportation, consumer, industry in the same period. 

In general, it can be seen that the proportion of emissions in developing countries tends to increase remarkably, which is projected to become the biggest slice of total. Moreover,  industry will be responsible for the highest amount of CO2 emissions.

According to the pie charts, the largest share of emissions in 2002 was OECD at 52%, but it is estimated to have lost its lead to developing countries with 48%, along with the projected figures in 2030. In spite of the rising trend of developing countries, over the period of prediction, the opposite will be true for countries with transition economics declining by 1% and OECD dropping from 52% down to 43%. 

Looking at the bar chart in more detail, industry will continue to be the major producer of carbon footprint with more than 10 billion tons for this sector. Consumer, becoming the second highest sector, is likely to two-fold increase from less than 4 billion to over 8 billion tons. The period will witness  a significant rise in transportation, growing to 6 billion, triple the amount in 2002, making it become the third largest producer. By comparison, waste contribution and other sectors are on the list as well, but produce a smaller amount of emissions.
