Biochar: Examination of an Emerging Concept to Mitigate Climate Change

Biochar: Examination of an Emerging Concept to Mitigate Climate Change

Date: May 24, 2010
Creator: Bracmort, Kelsi S.
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.

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

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

Date: November 24, 2014
Creator: Ramseur, Jonathan L.
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.
