Ocean Acidification

Ocean Acidification

Date: July 2, 2009
Creator: Buck, Eugene H. & Folger, Peter
Description: With increasing concentrations of carbon dioxide (CO2) in the atmosphere, the extent of effects on the ocean and marine resources is an increasing concern. One aspect of this issue is the ongoing process whereby seawater becomes acidified (i.e., ocean acidification) as more CO2 dissolves in it, causing hydrogen ion concentration in seawater to increase. While not yet fully understood, the ecological and economic consequences of ocean acidification could be substantial. Congress is beginning to focus attention on better understanding ocean acidification and determining how this concern might be addressed.

Carbon Capture and Sequestration (CCS)

Carbon Capture and Sequestration (CCS)

Date: June 19, 2009
Creator: Folger, Peter
Description: Carbon capture and sequestration (or storage) - known as CCS - has attracted interest as a measure for mitigating global climate change because large amounts of carbon dioxide (CO2) emitted from fossil fuel use in the United States are potentially available to be captured and stored underground or prevented from reaching the atmosphere. Congressional interest has grown in CCS as part of legislative strategies to address climate change. The large and rapid influx of funding for industrial-scale CCS projects may accelerate development and deployment of CO2 capture technologies.

Estimates of Carbon Mitigation Potential from Agricultural and Forestry Activities

Estimates of Carbon Mitigation Potential from Agricultural and Forestry Activities

Date: February 20, 2009
Creator: Johnson, Renee; Gorte, Ross W.; Yacobucci, Brent D. & Schnepf, Randy
Description: The report is organized into three parts. The first provides a brief overview of the role of the agriculture and forestry sectors within the broader climate change debate, describing available estimates of current GHG emissions and carbon sequestration in the farm and forestry sectors. The second describes available data and information on the potential for carbon storage (tonnage) by type of farming and forestry activity, and presents available estimates of the carbon sequestration potential in these sectors. The final part discusses some of the limitations of available estimates of GHG mitigation potential in the agriculture and forestry sectors, focusing on recent policy and market changes and other types of modeling uncertainties that could limit the accuracy of available mitigation projections.

Climate Change: The Role of the U.S. Agriculture Sector and Congressional Action

Climate Change: The Role of the U.S. Agriculture Sector and Congressional Action

Date: June 19, 2009
Creator: Johnson, Renée
Description: The debate in Congress over whether and how to address possible future climate change is intensifying. Often, the role of the U.S. agriculture sector is invoked in this debate. Agriculture is a source of greenhouse gas (GHG) emissions, which many scientists agree are contributing to observed climate change. Congress is considering a range of climate change policy options, including GHG emission reduction programs that would either mandate or authorize a cap-and-trade program to reduce GHG emissions. This report discusses this issue in detail, i.e., how the agricultural industry affects GHG emissions and efforts currently underway to combat these negative effects, but it does not address the potential effects of global climate change on U.S. agricultural production.

Estimates of Carbon Mitigation Potential from Agricultural and Forestry Activities

Estimates of Carbon Mitigation Potential from Agricultural and Forestry Activities

Date: June 19, 2009
Creator: Johnson, Renée; Gorte, Ross W.; Yacobucci, Brent D. & Schnepf, Randy
Description: Numerous theoretical and empirical studies estimate the greenhouse gas (GHG) mitigation potential of farm and forestry activities, and suggest that the potential for carbon uptake in agricultural soils and forest lands is much greater than current rates. Following a discussion of the estimated current emissions and carbon sequestration by the agricultural and forestry sectors, this report presents a brief overview of the available estimates from USDA and EPA carbon mitigation studies, and then discusses some of the limitations of the available data and modeling results. This report is organized into four parts, including a brief overview of the agriculture and forestry sectors within the broader climate change debate, as well as various data and information on potential for carbon storage and mitigation from farming and forestry activities.

Cars and Climate: What Can EPA Do to Control Greenhouse Gases from Mobile Sources?

Cars and Climate: What Can EPA Do to Control Greenhouse Gases from Mobile Sources?

Date: April 20, 2009
Creator: McCarthy, James E.
Description: This report discusses legislation being considered by congress to reduce the greenhouse gas (GHG) emissions that contribute to climate change. It discusses the EPA's authority under Title II and provides information regarding the mobile sources that might be regulated under this authority. Among these sources, motor vehicles (passenger cars and light trucks, including SUVs) are assumed to be the most likely initial targets for regulation, both because a petition addressing these sources began EPA's consideration of the endangerment issue, and because these are the most significant GHG emission sources among those covered by Title II.
