Broken down by household, each household is likely to pay an average of $83 extra each year in energy costs over that time period. Rolling back pollution standards stops people from adopting cleaner, more fuel efficient technologies. Automakers might meet those requirements by developing more efficient chassis, cleaner-burning engines, or designing and selling more electric vehicles. Repealing the greenhouse gas standards could lead to as many as 700 pollution-related premature deaths per year, the analysis finds. It also assumes lower gas prices and only takes into account two and a half years of fuel savings, Baldwin points out.
