A letter report issued by the Government Accountability Office with an abstract that begins "Coal power plants generate about half of the United States' electricity and are expected to remain a key energy source. Coal power plants also account for about one-third of the nation's emissions of carbon dioxide (CO2 ), the primary greenhouse gas that experts believe contributes to climate change. Current regulatory efforts and proposed legislation that seek to reduce CO2 emissions could affect coal power plants. Two key technologies show potential for reducing CO2 emissions: (1) carbon capture and storage (CCS), which involves capturing and storing CO2 in geologic formations, and (2) plant efficiency improvements that allow plants to use less coal. The Department of Energy (DOE) plays a key role in accelerating the commercial availability of these technologies and devoted more than $600 million to them in fiscal year 2009. Congress asked GAO to examine (1) the maturity of these technologies; (2) their potential for commercial use, and any challenges to their use; and (3) possible implications of deploying these technologies. To conduct this work, GAO reviewed reports and interviewed stakeholders with expertise in coal technologies."

Testimony issued by the Government Accountability Office with an abstract that begins "Federal entities--agencies, corporations, and others--are growing users of credit and debit cards, as both "merchants" (receiving payments) and purchasers. Federal entities, like other merchants that accept cards, incur fees--called merchant discount fees--to process card transactions. For Visa and MasterCard transactions, a large portion of these fees-- referred to as interchange fees--goes to the card-issuing banks. This statement addresses (1) the amounts of revenue that federal entities have collected using credit and debit cards and the costs of such acceptance, (2) these entities' efforts to reduce their interchange fee costs, including negotiations, and (3) the extent to which card network rules affect these entities and other card accepters' ability to reduce interchange fee costs. The information for this statement was drawn from Credit and Debit Cards: Federal Entities Are Taking Actions to Limit Their Interchange Fees, but Additional Revenue Collection Cost Savings May Exist (GAO-08-558) and Credit Cards: Rising Interchange Fees Have Increased Costs for Merchants, but Options for Reducing Fees Pose Challenges (GAO-10-45). GAO analyzed data on accepting and using cards from the Department of the Treasury (Treasury), Amtrak, the Postal Service, and General Services Administration (GSA); and …

Testimony issued by the Government Accountability Office with an abstract that begins "Pervasive and sustained cyber attacks continue to pose a potentially devastating threat to the systems and operations of the federal government. In recent testimony, the Director of National Intelligence highlighted that many nation states, terrorist networks, and organized criminal groups have the capability to target elements of the United States information infrastructure for intelligence collection, intellectual property theft, or disruption. In July 2009, press accounts reported attacks on Web sites operated by major government agencies. The ever-increasing dependence of federal agencies on information systems to carry out essential, everyday operations can make them vulnerable to an array of cyber-based risks. Thus it is increasingly important that the federal government carry out a concerted effort to safeguard its systems and the information they contain. GAO is providing a statement describing (1) cyber threats to federal information systems and cyber-based critical infrastructures, (2) control deficiencies that make federal systems vulnerable to those threats, and (3) opportunities that exist for improving federal cybersecurity. In preparing this statement, GAO relied on its previously published work in this area."

A letter report issued by the Government Accountability Office with an abstract that begins "The American Recovery and Reinvestment Act of 2009 (Recovery Act) provided the General Services Administration (GSA) with $5.55 billion to invest in federal buildings and promote economic recovery. This funding includes $4.5 billion to convert buildings to high-performance green buildings (HPGB), which seek to reduce energy and water use, among other goals. GAO was asked to address the (1) steps GSA has taken to implement the program and make its Recovery Act projects transparent to the public, (2) extent to which GSA's Recovery Act projects are helping the agency convert buildings to HPGB and addressing federal energy and water conservation requirements and goals, and (3) extent to which GSA has identified potential risks to its Recovery Act program and developed strategies to mitigate those risks. GAO reviewed GSA documents and relevant laws and executive orders, and interviewed GSA officials at headquarters and staff for 12 projects, which varied in type, size, and location."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2006, Congress passed the Haitian Hemispheric Opportunity through Partnership Encouragement Act (HOPE), giving preferential access to U.S. imports of Haitian apparel. In 2008, Congress amended HOPE (now HOPE II), expanding existing trade preference provisions and creating new ones, including the Earned Import Allowance Program (EIAP). Under the EIAP, for every 3-square- meter equivalents (SME) of U.S. or other qualifying fabric a firm imports into Haiti, it earns a credit to export 1 SME of apparel produced in Haiti to the United States, duty-free, regardless of the fabric source. The Haiti Economic Lift Program (HELP) Act of 2010 amended the EIAP, reducing the qualifying fabric requirement from 3 to 2. HOPE II also mandated GAO to review the effectiveness of the EIAP and to look for potential improvements. GAO examined (1) the extent to which the program has been used, (2) how U.S. government agencies implemented it, and (3) how might the program be improved. To address these questions GAO reviewed data from the Department of Commerce's Office of Textiles and Apparel (OTEXA); interviewed U.S. agency officials, Haitian and Dominican apparel producers, U.S. apparel buyers, and …

Testimony issued by the Government Accountability Office with an abstract that begins "On April 20, 2010, an explosion at the mobile offshore drilling unit Deepwater Horizon resulted in a massive oil spill in the Gulf of Mexico. The spill's total cost is unknown, but may result in considerable costs to the private sector, as well as federal, state, and local governments. The Oil Pollution Act of 1990 (OPA) set up a system that places the liability--up to specified limits--on the responsible party. The Oil Spill Liability Trust Fund (Fund), administered by the Coast Guard, pays for costs not paid for by the responsible party. GAO previously reported on the Fund and factors driving the cost of oil spills and is beginning work on the April 2010 spill. This testimony focuses on (1) how oil spills are paid for, (2) the factors that affect major oil spill costs, and (3) implications of major oil spill costs for the Fund. It is largely based on GAO's 2007 report, for which GAO analyzed oil spill cost data and reviewed documentation on the Fund's balance and vessels' limits of liability. To update the report, GAO obtained information from and interviewed Coast Guard officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Deteriorating financial conditions and declining mail volume have reinforced the need for the U.S. Postal Service (USPS) to increase operational efficiency and reduce expenses in its mail processing network. This network consists of interdependent functions in nearly 600 facilities. USPS developed several initiatives to reduce costs and increase efficiency; however, moving forward on some initiatives has been challenging because of the complexities involved in consolidating operations. In response to a conference report directive, GAO assessed (1) the overall status and results of USPS's efforts to realign its mail processing network and (2) the extent to which USPS has consistently followed its guidance and applied these criteria in reviewing Area Mail Processing (AMP) proposals for consolidation since the beginning of fiscal year 2009. To conduct this assessment, GAO reviewed USPS's Network Plan, area mail processing consolidation guidance and proposals as well as other documents; compared USPS's actions related to consolidation of area mail processing facilities with its guidance, and interviewed officials from USPS, the USPS Office of Inspector General, and employee organizations. GAO provided USPS with a draft of this report for comment. In response, USPS provided …
