Aviation and Climate Change: Aircraft Emissions Expected to Grow, but Technological and Operational Improvements and Government Policies Can Help Control Emissions
GAO-09-554: Published: Jun 8, 2009. Publicly Released: Jun 8, 2009.
Aircraft emit greenhouse gases and other emissions, contributing to increasing concentrations of such gases in the atmosphere. Many scientists and the Intergovernmental Panel on Climate Change (IPCC)--a United Nations organization that assesses scientific, technical, and economic information on climate change--believe these gases may negatively affect the earth's climate. Given forecasts of growth...
Climate Change: Observations on Federal Efforts to Adapt to a Changing Climate
GAO-09-534T: Published: Mar 25, 2009. Publicly Released: Mar 25, 2009.
Changes in the climate attributable to increased concentrations of greenhouse gases may have significant environmental and economic impacts in the United States. For example, climate change could threaten coastal areas with rising sea levels, alter agricultural productivity, and increase the intensity and frequency of floods and storms. Federal, state, and local agencies are tasked with a wide arr...
Environmental Protection Agency: Major Management Challenges
GAO-09-434: Published: Mar 4, 2009. Publicly Released: Mar 4, 2009.
The Environmental Protection Agency's (EPA) overarching mission is to protect human health and the environment by implementing and enforcing environmental laws intended to improve the quality of the nation's air and water and to protect its land. EPA's policies and programs affect virtually all segments of the economy, society, and government. As such, it operates in a highly complex and controver...
Chemical Regulation: Options for Enhancing the Effectiveness of the Toxic Substances Control Act
GAO-09-428T: Published: Feb 26, 2009. Publicly Released: Feb 26, 2009.
Congress passed the Toxic Substances Control Act (TSCA) in 1976, authorizing the Environmental Protection Agency (EPA) to obtain information on the risks of industrial chemicals and to control those that EPA determines pose an unreasonable risk. However, EPA does not have sufficient chemical assessment information to determine whether it should establish controls to limit public exposure to many c...
Hardrock Mining: Information on Types of State Royalties, Number of Abandoned Mines, and Financial Assurances on BLM Land
GAO-09-429T: Published: Feb 26, 2009. Publicly Released: Feb 26, 2009.
The General Mining Act of 1872 helped open the West by allowing individuals to obtain exclusive rights to mine billions of dollars worth of gold, silver, and other hardrock (locatable) minerals from federal lands without having to pay a federal royalty. However, western states charge royalties so that they share in the proceeds from various hardrock minerals extracted from their lands. For years,...
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...
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...
Concentrated Animal Feeding Operations: EPA Needs More Information and a Clearly Defined Strategy to Protect Air and Water Quality from Pollutants of Concern
GAO-08-944: Published: Sep 4, 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 can improve the efficiency of animal production but large amounts of manure produce can, if not properly managed, degrade air and water quality. The Environmental Protection Agency (EPA) is responsible for regulating CAFOs and requires CAFOs that discharge cert...
Electronic Waste: EPA Needs to Better Control Harmful U.S. Exports through Stronger Enforcement and More Comprehensive Regulation
GAO-08-1044: Published: Aug 28, 2008. Publicly Released: Sep 17, 2008.
Increasingly, U.S. consumers are recycling their old electronics to prevent the environmental harm that can come from disposal. Concerns have grown, however, that some U.S. companies are exporting these items to developing countries, where unsafe recycling practices can cause health and environmental problems. Items with cathode-ray tubes (CRT) are particularly harmful because they can contain 4 p...
