Sources of Greenhouse Gas Emissions Presentation 10:24 video

This nearly wordless pdf uses graphics to show the sources of greenhouse gas emissions, as identified by the United States Environmental Protection Agency. When the EPA uses broad economic systems to classify GHG emissions, they have found some surprising things. The four categories of Infrastructure, Use of Appliances and Devices, Personal Transportation, and Heating and Cooling all totaled contribute 58% of the nation's greenhouse gas emissions.  

The single largest contributor, however, is Materials-what we know of as the "stuff of life."  

Slides 1-19 explain with pictures these facts.  Slides 20-38 then explain--with graphics--why "stuff" generates so many GHG emissions. What you'll discover may surprise you!
