Would a cap and trade system to curb greenhouse gases, like that being offered by Senators John Warner and Joseph Lieberman, adversely impact the US economy? It certainly would, at least according to a new study by the National Association of Manufacturers. Comments spokesperson Laura Narvaiz: “The conclusions of our report indicate that the legislation would reduce our Gross Domestic Product by at least $151 billion, eliminate 1.2 million jobs, reduce household income by nearly $3,000 per year, increase electricity prices by around 30% and gasoline prices somewhere between 20 and 69%, and all this by 2020. This global warming legislation is hardly pain free to our economy.”
