If we have a look at this Pie Chart which is about  Annual Greenhouse Emissions by Sector,  you will notice that the waste disposal and treatment in particular is only slightly more than four percent, while the land use and biomass burning, Residential, commercial and other sources rose steadily around 10% ,then an  insignificant  increase of the percent of Fossil fuel retrieval, processing and distribution, also we can observe the Agricultural byproducts increased slightly around one and a half percent,then the same moderate rise of  the percent of  the transportation fuels , followed by a significant take off of the percent of emissions from industrial processes which  is around three percent, then as can be seen from the chart that the percent of the power station is increased  dramatically .      

                                                                                                                                      Which is due to the industrial facility for generation of electric power as we all know.

Thank you.
