Carbon Dioxide

Carbon dioxide plays an important role in causing global warming, because it’s the major outcome of pollution in general. Mainly these carbon dioxide emissions occurre as an upshot of burning materials especially fossil fuels. There are many sources of carbon dioxide such as trucks. About 13% of U.S carbon dioxide emissions come from trucks used mostly for commercial purposes. Also we can mention airplanes emissions. The UN's Intergovernmental Panel on climate Change estimates that aviation causes 3.5 percent of global warming, and that the figure could rise to 15 percent by 2050. The last source I would like to write about is carbon dioxide emissions from buildings.Buildings structure account for about 12% of carbon dioxide emissions.
