Carbon Dioxide Removal


Biochar

Biochar is a substance created when organic material like agricultural waste is burned in the absence of oxygen. That process, called pyrolysis, creates a carbon-rich product that is stable or biologically recalcitrant. By transforming biomass into biochar, the carbon in the plant material is locked up instead of being released into the atmosphere when the biomass is burned or biodegraded in soil. Biochar is added to soil to sequester carbon dioxide in the soil.

Climate Change Mitigation and Adaptation Policy Options: Reducing Australia’s Dependence on Coal, Natural Gas, and Other Nonrenewable Energy Resources

2011
Scholarly Work
Michael Jeffery
This article explores the role of industry in enabling Australia to move toward a less carbon intensive economy, with a closer look at industry's role in carbon capture and storage, afforestation and reforestation, and biochar technologies.

Assessing Greenhouse Gas Mitigation Opportunities and Implementation Strategies for Agricultural Land Management in the United States

2011
Scholarly Work
Lydia P. Olander, Alison J. Eagle, Justin S. Baker, Karen Haugen-Kozyra, Brian C. Murray, Alexandra Kravchenko, Lucy R. Henry, Robert B. Jackson
Provides a roadmap and resource for programs and initiatives that are designing protocols, metrics, or incentives to engage farmers and ranchers in large-scale efforts to enhance GHG mitigation on working agricultural land in the United States.

IPCC Expert Meeting on Geoengineering

2011
Scientific Report
Intergovernmental Panel on Climate Change (IPCC)
This meeting report summarizes discussions of three Working Groups to the IPCC's Fifth Assessment Report (AR5) on geoengineering, including carbon dioxide removal.

Adjusting Carbon Management Policies to Encourage Renewable, Net-Negative Projects Such as Biochar Sequestration

2010
Scholarly Work
Darrel Fruth, Joseph Ponzi
This article considers the present legal challenges to adjust carbon management policies, specifically carbon crediting schemes, for biochar as a carbon sequestration technique.

Evaluation of the Opportunities for Generating Carbon Offsets from Soil Sequestration of Biochar

2010
Scholarly Work
Steven De Gryze, Michael Cullen , Leslie Durschinger
This paper aims to provide a comprehensive review of the issues involved in generating carbon offsets from the production and incorporation of biochar into soil, with a focus on the use of biochar in the United States.

The Regulation of Geoengineering: Fifth Report of Session 2009–10

2010
Scientific Report
House of Commons Science and Technology Committee
This report, written in collaboration with the U.S. House of Representatives Science and Technology Committee, examines the need for the regulation of geoengineering activities and provides an outlines of future regulatory arrangements.

A Coordinated Strategy Could Focus Federal Geoengineering Research and Inform Governance Efforts

2010
Scientific Report
United States Government Accountability Office
This report examines the state of geoengineering science, federal involvement in geoengineering, the extent to which federal laws and international agreements apply to geoengineering, and any governance challenges around geoengineering activities.

Biochar and Waste Law: A Comparative Analysis

2009
Scholarly Work
Caroline Van de bergh
This article provides a comparative analyses whether biochar is waste in the EU and the US and whether the pyrolysis treatment, transportation and storage of biochar may be exempted from the regulatory burden placed on the classification of waste.

Biochar – One Way Forward for Soil Carbon in Offset Mechanisms in Africa?

2009
Scholarly Work
Thea Whitman , Johannes Lehmann
This paper explores how small-scale biochar systems with net emission reductions may hold a key for Africa to engage with the international offset mechanisms and open the door to soil carbon sequestration projects.

H.R.3748 – Water Efficiency via Carbon Harvesting and Restoration (WECHAR) Act of 2009

2009
Proposed Legislation
This bill sets up a joint Department of Interior and USDA loan guarantee program to commercialize biochar production units that produce net-negative carbon emissions.
