Correspondence issued by the Government Accountability Office with an abstract that begins "Older electricity generating units—those that began operating in or before 1978—provided 45 percent of electricity from fossil fuel units in 2010 but produced a disproportionate share of emissions, both in aggregate and per unit of electricity generated. Overall, in 2010 older units contributed 75 percent of sulfur dioxide emissions, 64 percent of nitrogen oxides emissions, and 54 percent of carbon dioxide emissions from fossil fuel units. For each unit of electricity generated, older units collectively emitted about 3.6 times as much sulfur dioxide, 2.1 times as much nitrogen oxides, and 1.3 times as much carbon dioxide as newer units. The difference in emissions between older units and their newer counterparts may be attributed to a number of factors. First, 93 percent of the electricity produced by older fossil fuel units in 2010 was generated by coal-fired units. Compared with natural gas units, coal-fired units produced over 90 times as much sulfur dioxide, twice as much carbon dioxide and over five times as much nitrogen oxides per unit of electricity, largely because coal contains more sulfur and carbon than natural gas. Second, fewer older units have installed emissions controls, …

Testimony issued by the Government Accountability Office with an abstract that begins "GAO’s recent work highlights the types of challenges facing the Department of Defense (DOD) as it strives to attain audit readiness and reengineer its business processes and systems. The urgency in addressing these challenges has been increased by the goals of an auditable DOD Statement of Budgetary Resources (SBR) by the end of fiscal year 2014 and a complete set of auditable financial statements by the end of fiscal year 2017. For example, GAO’s 2011 reporting highlights difficulties the DOD components experienced in attempting to achieve an auditable SBR. These include:"
