The Role of Offsets in a Greenhouse Gas Emissions Cap-and-Trade Program: Potential Benefits and Concerns

Description: This report discusses offsets in relation to a greenhouse gas emissions cap-and-trade program. The first section of this report provides an overview of offsets by discussing different types of offset projects and describing how the offsets would likely be used in an emission reduction program. The next section discusses the supply of offsets that might be available in an emission trading program. The subsequent sections examine the potential offset benefits and the potential concerns associated with offsets.

U.S. Greenhouse Gas Emissions: Recent Trends and Factors

Description: A question for policy makers is whether U.S. GHG emissions will remain at current levels, decrease to meet the President's 2020 and 2025 goals, or increase to former (or even higher) levels. Multiple factors, including socioeconomics, technology, and climate policies, may impact GHG emission levels. The first section of this report provides current levels and recent trends in U.S. GHG emissions. The second section takes a closer look at some of the key factors that influence emission levels. The third section discusses the challenges in making GHG emission projections by comparing observed emissions with pre-observed emission estimates.

Global Climate Change: Reducing Greenhouse Gases - How Much from What Baseline?

Description: This report discusses the ways to reduce emissions of six greenhouses gases after the Kyoto meeting on Global Climate Change. Projecting the reductions that would be required if the U.S. were to ratify the treaty is difficult. While emissions of CO are fairly well established and account for 2 about 85% of total carbon equivalent emissions, emissions of the other gases, especially N O, are more uncertain.

Biochar: Examination of an Emerging Concept to Mitigate Climate Change

Description: Biochar is a charcoal produced under high temperatures using crop residues, animal manure, or any type of organic waste material. Depending on the feedstock, biochar may look similar to potting soil or to a charred substance. The combined production and use of biochar is considered a carbon-negative process, meaning that it removes carbon from the atmosphere. This report briefly describes biochar, its potential advantages and disadvantages, legislative support, and research and development activities underway in the United States.
