The Deepwater Horizon Oil Spill: Coastal Wetland and Wildlife Impacts and Response
The explosion of the Deepwater Horizon drilling rig in the Gulf of Mexico on April 20, 2010, and the resulting oil spill began a cascade of effects on the coastal areas of the Gulf and on the wealth of species that inhabit those areas. This report addresses the importance of wetlands in general, the ecology of the coastal wetlands in the Gulf, impacts of oil spills on wetland habitats, response options, the implications of hurricane season for the spill's impacts, and cleanup and recovery issues. The emphasis is on the nearshore environment, although a few species found in deeper waters will be mentioned. In addition, some lessons from past spills such as the Exxon Valdez in Alaska will be discussed, along with issues that may arise as response and recovery transition to restoration of the Gulf.
Energy Efficiency and Renewable Energy Legislation in the 109th Congress
This report reviews the status of energy efficiency and renewable energy legislation introduced during the 109th Congress. Action in the second session has focused on appropriations bills; the first session focused on omnibus energy policy bill H.R. 6, H.R. 3, and several appropriations bills. For each bill listed in this report, a brief description and a summary of action are given, including references to committee hearings and reports. Also, a selected list of hearings on renewable energy is included. This report supplements the tracking of issues that appear in CRS Issue Brief IB10020 and CRS Issue Brief IB10041.
Energy's Water Demand: Trends, Vulnerabilities, and Management
The nation's energy choices embody many tradeoffs. Water use is one of those tradeoffs. The energy choices before Congress represent vastly different demands on domestic freshwater. The energy sector's water consumption is projected to rise 50% from 2005 to 2030. This rising water demand derives from both an increase in the amount of energy demanded and shifts to more water-intense energy sources and technologies. This report discusses this issue as well as related issues that may arise for the 112th Congress.
Global Climate Change
This report discusses different perspectives used to consider issues related to the global climate change and issues related to the 1992 U.N. Framework Convention on Climate Change and the 1997 Kyoto Agreement.
Global Climate Change and Wildlife
Recently projected climate changes could have widespread effects on wildlife species. These effects might be positive or negative, depending on the species. Some effects might include extinction, range shifts, mismatches in phenology (timing of pollination, flowering, etc.), and population changes. If the effects of climate change are widespread, there is uncertainty on how wildlife will adapt. Some suggest that evolution and migration will enable species to adapt, whereas others contend that adaptation will be minimal because of limited habitat, and changes in climate that may occur may rapidly than adaptation can respond.
Global Climate Change: Market-Based Strategies to Reduce Greenhouse Gases
This report discusses global climate change and the possibility that human activities are releasing gases, including carbon dioxide (CO2), at rates that could affect global climate change.
Global Climate Change: Status of Negotiations
In December 2007, the parties to the United Nations Framework Convention on Climate Change (UNFCCC) held their 13th annual meeting in Bali, Indonesia, and began the process of working toward an agreement/treaty that would succeed the Kyoto Protocol to the UNFCCC when it expires in 2012. The Protocol includes a mandate for a reduction of greenhouse gas (GHG) emissions by 30 developed/industrialized nations to an average of some 5% below their 1990 levels over the commitment period 2008-2012. The broad array of these issues, briefly discussed in this report, has been described by some as comprising perhaps the most complex negotiations ever undertaken internationally.
Global Climate Change: The Kyoto Protocol
Negotiations on the Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC) was completed on December 11, 1997, committing the industrialized nations to specified, legally binding reductions in emissions of six “greenhouse gases.” The Protocol entered into force on February 16, 2005, and its emissions reduction requirements are binding on the 35 industrialized countries that have ratified it; the United States disengaged from the Protocol in 2001 and has not ratified it.
Global Climate Change: The Role for Energy Efficiency
This report reviews the role of energy efficiency in federal policies to curb CO2 emissions. In particular, it discusses targets for CO2 reductions, projected energy efficiency impacts, strategies for measuring impacts, and legislative proposals that would affect support for energy efficiency programs.
Global Climate Change: U.S. Greenhouse Gas Emissions - Status, Trends, and Projections
According to the summary, this report reviews U.S. emissions of greenhouse gases in the contexts both of domestic policy and of international obligations and proposals.
International Climate Change: A Negotiations Side-by-Side
This report discusses various cooperative international efforts to address the issue of global climate change. The two major international agreements discussed in a side-by-side comparison are the 1997 Kyoto Protocol and the 2010 Copenhagen Accord. The report discusses how many observers are hoping that initiatives carried out under the Copenhagen Accord may help bridge divides between the various tracks and economic groupings established under the Kyoto Protocol.
Litigation Seeking to Establish Climate Change Impacts as a Common Law Nuisance
This report discusses recent legislative initiatives seeking to establish climate change impacts as a common law nuisance. The report explains what private and public nuisances are, the issues faced by policymakers when litigating a climate-change/nuisance suit, and also discusses five climate-chance/nuisance suits that are now or formerly active, as a basis of comparison. The report also explores arguments of those both for and against addressing the complex issue of climate change through common law suits.
Renewable Fuel Standard (RFS): Overview and Issues
This report focuses on the mandated minimum usage requirements - referred to as the Renewable Fuel Standard (RFS) - whereby a minimum volume of biofuels is to be used in the national transportation fuel supply each year. It describes the general nature of the biofuels RFS and its implementation, and outlines some of the emerging issues related to the sustainability of the continued growth in U.S. biofuels production needed to fulfill the expanding RFS mandate, as well as the emergence of potential unintended consequences of this rapid expansion. This report does not address the broader public policy issue of how best to support U.S. energy policy.
Seafood Safety: Background and Issues
Although seafood consumption can contribute to a healthy diet, some fish and shellfish can cause foodborne illnesses or contain environmental contaminants. This report discusses whether current food safety programs are sufficiently protecting consumers, and if not, what changes should be considered.
