This is the first in a series of articles, that will examine point source greenhouse gas (GHG) emissions, in the United States (US), as well as the development of Renewable Energy to mitigate these emissions. This article looks at the history of regulating point source GHG, in the US, from Direct Emitters such as power utilities, industry and farms. In the past few years the US has made significant progress towards this goal, by having the Environmental Protection Agency's (EPA) develop the Greenhouse Gas Reporting Program (GHGRP).
