Conversely, although nuclear energy accounts for less than 10 percent of the GHG
emission reduction potentials across all scenarios, it has received some 50 percent of the
total public investment in energy technology R&D.
Requires the EPA Administrator to: (1) identify those classes or categories of new nonroad vehicles or engines that contribute significantly to the
total GHG
emissions from such vehicles and that provide the greatest
potential for significant and cost - effective
reduction of such
emissions; and (2) promulgate standards applicable to GHG
emissions from these engines or vehicles by December 31, 2012; and (3) promulgate standards applicable to GHG
emissions for other classes and categories of vehicles and engines as the EPA Administrator determines appropriate.
