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 believe these gases may negatively affect the earthżs climate. Given forecasts of growth in aviation emissions, some govżts. are taking steps to reduce emissions. This report reviews: (1) estimates of aviationżs current and future contribution to greenhouse gas and other emissions that may affect climate change; (2) existing and potential technological and operational improvements that can reduce airc

Elevated levels of greenhouse gases in the atmosphere and the resulting effects on the earth's climate could have significant impacts in the U.S. and internationally. The U.S. Congress is considering proposals to limit greenhouse gas emissions using market-based mechanisms that would place a price on emissions. A greenhouse gas mitigation program requires an understanding of the emissions sources of 6 major greenhouse gases -- carbon dioxide, methane, nitrous oxide, and several synthetic gases. This testimony focuses on: (1) the importance of quality data on emissions in the context of a progr

Presents a glossary of terms related to the subject of biomass energy -- the combustion of renewable organic matter for the production of fuel, energy, or steam for the generation of electricity, mechanical power, or industrial process heat. Tables include temperature conversion, physical constants applying to the individual gases encountered most frequently in fuel gases, and optimum yarding distances and slope percent of logging systems. Illustrated.

Human activities are yielding rising atmospheric concentrations of greenhouse gases and other gases and particulates and are also greatly altering the Earthżs land cover. These activities, if allowed to continue unabated, will have extensive, highly uncertain, but potentially serious and costly impacts on regional climates and ocean conditions throughout the world. Here is an overview of the current understanding of the impacts of climate change in the U.S., emphasizing the wide range of uncertainty about the magnitude and timing of those impacts and the implications of that uncertainty for t

Discussions about reducing greenhouse gases (GC) often focus on limiting the use of fossil fuels to generate electricity or power cars and trucks, yet a variety of other actions ż incl. disposing of waste in different ways, changing methods of farming, and lessening deforestation ż could also reduce the concentration of GC in the atmosphere. Although experience with offsets is not extensive, evidence suggests that they can significantly lower the economic cost of a cap-and-trade program, even after accounting for the costs of steps taken to increase confidence that offsets represent true inc

Research on climate change has identified a wide array of sources that emit greenhouse gases (GHGs). Among the 6 gases that have been the primary focus of concern, methane is the second-most abundant, accounting for approximately 8% of total U.S. GHG emissions in 2008. Methane is emitted from a number of sources. The most significant are agriculture (both animal digestive systems and manure management); landfills; oil and gas production, refining, and distribution; and coal mining. This report discusses alternatives for addressing methane capture, sources of methane, opportunities and challeng
