Annual Greenhouse Emissions by Sector

This pie chart represents the annual greenhouse emissions by sector. It is clear from the graph that there are many sectors that contribute on the greenhouse gases. For example, the sector of residential, commercial and other sources emit 10.3% of greenhouse gases per year. The same quantity is almost emitted by using the land and burning the biomass. Then, the waste disposal and treatment add only 4.3% for the greenhouse gases. However, as be can seen from the graph, the power stations are the main sector of the greenhouse gases, they contribute by 21.3% per year. In addition, the industrial processes, the transportation and the agricultural emit 16.8%, 14% and 12.5%, respectively. Finally, 11.3% of this emission is from the fossil fuels. Therefore, the greenhouse gases are contributed from different sectors with different percentages.
