Climate Change Science: High Quality Greenhouse Gas Emissions Data are a Cornerstone of Programs to Address Climate Change
GAO-09-423T: Published: Feb 24, 2009. Publicly Released: Feb 24, 2009.
Elevated levels of greenhouse gases in the atmosphere and the resulting effects on the earth's climate could have significant impacts in the United States and internationally. Potential impacts include a change in sea levels, ecosystems, and ice cover. The United States Congress is considering proposals to limit greenhouse gas emissions using market-based mechanisms that would place a price on emi...
Clean Air Act: Historical Information on EPA's Process for Reviewing California Waiver Requests and Making Waiver Determinations
GAO-09-249R: Published: Jan 16, 2009. Publicly Released: Feb 17, 2009.
Emissions from mobile sources, such as automobiles and trucks, contribute to air quality degradation and can threaten public health and the environment. Under the Clean Air Act, the Environmental Protection Agency (EPA) regulates these emissions. The act generally allows one set of federal standards for new motor vehicle emissions and pre-empts states from adopting or enforcing their own standards...
Aviation and the Environment: Initial Voluntary Airport Low Emissions Program Projects Reduce Emissions, and FAA Plans to Assess the Program's Overall Performance as Participation Increases
GAO-09-37: Published: Nov 7, 2008. Publicly Released: Nov 7, 2008.
In 2003, Congress established a program to reduce airport ground emissions at commercial service airports in areas failing to meet or maintain air quality standards. The Federal Aviation Administration (FAA) administers the Voluntary Airport Low Emissions (VALE) Program and oversees the program's two sources of funding: Airport Improvement Program (AIP) federal grants or Passenger Facility Charges...
Environmental Enforcement: EPA Needs to Improve the Accuracy and Transparency of Measures Used to Report on Program Effectiveness
GAO-08-1111R: Published: Sep 18, 2008. Publicly Released: Oct 21, 2008.
As part of its mission to protect human health and the environment, the Environmental Protection Agency's (EPA) enforcement office maintains civil and criminal enforcement programs to help enforce the requirements of major federal environmental laws such as the Clean Air Act and the Clean Water Act. EPA's civil and criminal enforcement programs work with the Department of Justice (DOJ), and in som...
Green Affordable Housing: HUD Has Made Progress in Promoting Green Building, but Expanding Efforts Could Help Reduce Energy Costs and Benefit Tenants
GAO-09-46: Published: Oct 7, 2008. Publicly Released: Oct 7, 2008.
Rising energy prices and concerns about the environment have fueled interest in "green building"--resource-efficient construction and maintenance practices that reduce adverse impacts on the natural environment. The Department of Housing and Urban Development (HUD), spends an estimated $5 billion on energy costs annually in its affordable housing programs and has recently taken steps to reduce its...
Climate Change: Federal Actions Will Greatly Affect the Viability of Carbon Capture and Storage As a Key Mitigation Option
GAO-08-1080: Published: Sep 30, 2008. Publicly Released: Sep 30, 2008.
Key scientific assessments have underscored the urgency of reducing emissions of carbon dioxide (CO2) to address climate change. Many have cited carbon capture and storage (CCS) as an essential technology because it has the potential to greatly reduce CO2 emissions from power plants while allowing for projected increases in electricity demand. CCS involves capturing CO2 from a power plant's emissi...
Recent Actions by the Chesapeake Bay Program Are Positive Steps Toward More Effectively Guiding the Restoration Effort, but Additional Steps Are Needed
GAO-08-1131R: Published: Aug 28, 2008. Publicly Released: Sep 26, 2008.
Since 1983, the states of Maryland, Pennsylvania, and Virginia; the District of Columbia; the Chesapeake Bay Commission; and the Environmental Protection Agency (EPA) have partnered to protect and restore the deteriorated Chesapeake Bay ecosystem. The partners established the Chesapeake Bay Program (Bay Program) to manage and coordinate a variety of restoration activities and in their most recent...
Concentrated Animal Feeding Operations: EPA Needs More Information and a Clearly Defined Strategy to Protect Air and Water Quality
GAO-08-1177T: Published: Sep 24, 2008. Publicly Released: Sep 24, 2008.
Concentrated animal feeding operations (CAFO) are large livestock and poultry operations that raise animals in a confined situation. CAFOs may improve the efficiency of animal production, but the large amounts of manure they produce can, if improperly managed, degrade air and water quality. The Environmental Protection Agency (EPA) regulates CAFOs and requires CAFOs that discharge certain pollutan...
Wildlife Refuges: Changes in Funding, Staffing, and Other Factors Create Concerns about Future Sustainability
GAO-08-797: Published: Sep 22, 2008. Publicly Released: Sep 24, 2008.
The National Wildlife Refuge System, which is administered by the Fish and Wildlife Service in the Department of the Interior, comprises 585 refuges on more than 96 million acres of land and water that preserve habitat for waterfowl and other migratory birds, threatened and endangered species, and other wildlife. Refuges also provide wildlife-related activities such as hunting and fishing to nearl...
