Nearly two years ago, I wrote that transportation was “the leading contiributor to greenhouse gases (GHGs) in the country, according to a report by the U.S. Department of Energy (DOE), and… the fastest growing contributor.”

Now, in other terms and looking at additional factors, NASA has determined that automobiles are the largest net contributor to climate change pollution.

In other words, when you take into account the climate change (or global warming) gases automobiles emit as well as gases they emit that have a cooling effect, automobiles are the largest contributor to climate change, followed by 2) burning of household biofuels (i.e. wood and animal dung) and 3) raising livestock.
